TECHNICAL FIELD

[0002] The present invention relates to a nutrient delivery system for providing a nutritional formula and use of the same.

BACKGROUND

[0003] Not all infants are in a position to receive human breast milk. It is therefore desirable to provide nutritional compositions, such as synthetic infant formulas, that can produce nutritional benefits in infants. Typical infant formulas are provided as packaged bulk powders, which a user must reconstitute by measuring out a specified amount of powder and adding it to an appropriate volume of liquid with shaking. This can lead to inconsistent amounts of both powder and liquid being used, and can lead to significant air being introduced into the formula when it is shaken. Furthermore, an infant formula is typically heated prior to consumption by the infant. However, heating infant formula through traditional methods can lead to deactivation of essential nutrients and vitamins. In addition, constant temperature monitoring is required to ensure that the infant formula is at the ideal temperature for easy consumption by the infant, leading to potential delays in providing an infant with formula in a timely manner.

[0004] To address the above concerns, it would be beneficial to provide nutritional compositions in an inexpensive and convenient manner, with all of the desirable nutrient deliverables at a proper temperature, and yet to provide the parent or caretaker a decrease in time for preparation. One such system is a single-serving pod system that could provide single bottle infant formulas in minutes with the proper nutrients for the infant, at the proper temperature. Issues related to proper reconstitution of the powder, lack of appropriate mixing in the pod, ensuring water safety, and minimizing or eliminating growth of microorganisms are challenges for current single -use pod systems for any type of liquid deliverable such as coffee or other nutrient formulations. Another issue is the expense and environmental impact of these single- serving pod systems.

[0005] Accordingly, there is a need for a single use pod system for providing nutritional compositions, such as infant formulas, which addresses the issues outlined above.

DETAILED DESCRIPTION

[0039] The present invention relates to a nutrient delivery system. The nutrient delivery system comprises a pod and a nutritional powder located within the pod. The pod includes a lid and together the lid and nutritional powder define therebetween a headspace of the pod. The headspace may include less than about 10% oxygen, thereby preventing oxidation of the nutritional powder and the presence of undesirable flavors, odors, and textures in a nutritional formula provided by the nutrient delivery system. In particular, the nutrient delivery system provides the nutritional formula when a fluid such as water is introduced into the pod to form a mixture of the fluid and nutritional powder and this mixture is expelled from the pod as the nutritional formula.

[0040] The nutritional powder includes protein. The protein may bind a mineral, for example, such as, but not limited to, zinc and iron, such that upon ingestion of the nutritional formula by the subject, the mineral is delivered to the subject. The protein may also lend the nutritional formula improved digestibility relative to a nutritional formula that does not contain the protein in the amounts as described below. In particular, digestibility may be improved when the protein has a degree of hydrolysis of about 0 to about 60. A degree of hydrolysis of about 0 to about 60 may also increase the solubility of the protein in the nutritional formula, which in turn, may increase the emulsion capacity of and mineral delivery by the nutritional formula. This degree of hydrolysis of about 0 to about 60 may not introduce detrimental features into the nutritional formula such as compromised sensory quality and decreased protein functionality.

[0041] Additionally, the protein may be a source of one or more isoflavones, one or more phytosterols, one or more polyphenols, or any combination thereof. The one or more isoflavones may provide antioxidant activity, cholesterol lowering activity, radical scavenging, and/or cytoprotection. The one or more phytosterols may reduce serum or plasma total cholesterol and/or low density lipoprotein (LDL) levels in the subject after ingestion and digestion of the nutritional formula by the subject. The one or more phytosterols may exhibit one or more antitumor properties in the subject after ingestion and digestion of the nutritional formula.

[0042] An additional source of the one or more isoflavones, the one or more phytosterols, and the one or more polyphenols may be a fat such as oil and thus, the nutritional powder may also include oil as described below in more detail.

[0068] "Total protein" and "total amount of protein" are used interchangeably in connection with the amount of protein in a protein system or a particular nutritional composition to mean all the protein in that system or composition.

[0069] To the extent that the terms "includes," "including," "contains," or "containing" are used herein, they are intended to be inclusive in a manner similar to the term "comprising" as that term is interpreted when employed as a transitional word in a claim. Furthermore, to the extent that the term "or" is employed (e.g., A or B) it is intended to mean "A or B or both." When the applicants intend to indicate "only A or B but not both" then the term "only A or B but not both" will be employed. Thus, use of the term "or" herein is the inclusive, and not the exclusive use. Also, to the extent that the terms "in" or "into" are used herein, they are intended to additionally mean "on" or "onto."

[0070] All percentages, parts and ratios as used herein are by weight of the total product, unless specified otherwise.

2. Nutrient Delivery System

[0077] Provided herein is a nutrient delivery system. This system includes a nutritional powder, and the system provides a nutritional formula for consumption. This nutritional formula may be ingested by an infant and thus, provides the infant nutrients needed for proper

development and growth. The nutritional formula may also be ingested by a toddler or child, for proper delivery of nutrients for continued development and growth. The nutritional formula may also be ingested by an adult, as a nutritional supplement. The system also includes a pod, which contains the nutritional powder. The nutritional powder may be contained in the pod such that a headspace in the pod includes a maximum of about 10% O ₂ (i.e., less than or equal to about 10% O ₂ ), thereby reducing oxidation of the nutritional powder or formula and preventing the development of undesirable flavors, smells, and textures. Prior to ingestion of the nutritional formula, water is introduced into the pod to form a mixture of the water and the nutritional powder, ultimately providing the nutritional formula. The temperature of the water may be about 5°C to 60 °C, e.g., about 25°C to about 50 °C, to allow reconstitution of the nutritional powder to provide the nutritional formula. For example, the temperature of the water may be about 5 °C, 6°C , 7 °C, 8 °C, 9 °C, 10°C, 11 °C, 12 °C, 13 °C, 14 °C, 15 °C, 16°C, 17 °C, 18 °C, 19 °C, 20 °C, 21°C , 22 °C, 23 °C, 24°C , 25 °C, 26 °C, 27 °C, 28 °C, 29°C, 30°C , 31 °C, 32 °C, 33 °C, 34°C , 35°C , 36 °C, 37 °C, 38 °C, 39 °C, 40°C, 41 °C , 42 °C, 43 °C, 44 °C, 45 °C, 46°C, 47 °C, 48°C , 49 °C, 50°C, 51 °C , 52 °C, 53 °C, 54 °C, 55 °C, 56°C, 57°C , 58 °C, 59 °C, or 60 °C. The resulting nutritional formula is then discharged from the pod into a container suitable for facilitating consumption of the nutritional formula by an individual (e.g., infant, toddler, child or adult). a. Nutritional Powder

[0078] The nutrient delivery system may comprise a nutritional powder that is within a pod and delivers a nutritional formula. The nutritional powder includes compounds that affect the overall physical characteristics of the nutritional formula. The nutritional powder is sealed in the pod and is measured in an amount that provides the optimal nutritional formula when used in the nutrient delivery system. The physical characteristics that are important for the overall function of the nutritional powder include powder reconstitution characteristics (e.g., wettability), viscosity, foaming, emulsion stability, amino acid profile, mineral delivery, antioxidant capacity, shelf-life stability, odor, flavor, and digestibility.

[0079] The nutritional powder includes protein as described below in more detail. The protein may bind a mineral, for example, such as, but not limited to, zinc and iron, such that upon ingestion of the nutritional formula, which is described below in more detail, by the subject, the mineral is delivered to the subject. The protein may also lend the nutritional formula improved digestibility relative to a nutritional formula that does not contain the protein in the amounts described below. In particular, digestibility may be improved when the protein has a degree of hydrolysis of about 0 to about 60. A degree of hydrolysis of about 0 to about 60 may also increase the solubility of the protein in the nutritional formula, which in turn, may increase the emulsion capacity of and mineral delivery by the nutritional formula. This degree of hydrolysis of about 0 to about 60 may not introduce detrimental features into the nutritional formula such as compromised sensory quality and decreased protein functionality.

[0080] Additionally, as described below in more detail, the protein may be a source of one or more isoflavones, one or more phytosterols, one or more polyphenols, or any combination thereof. The one or more isoflavones may provide antioxidant activity, cholesterol lowering activity, radical scavenging, and/or cytoprotection. The one or more phyto sterols may reduce serum or plasma total cholesterol and/or low density lipoprotein (LDL) levels in the subject after ingestion and digestion of the nutritional formula by the subject. The one or more phytosterols may exhibit one or more anti-tumor properties in the subject after ingestion and digestion of the nutritional formula.

[0081] As described below in more detail, an additional source of the one or more

isoflavones, the one or more phytosterols, and the one or more polyphenols may be a fat such as oil and thus, the nutritional powder may also include oil as described below in more detail.

(1) Size and Shape

[0082] The nutritional powder may comprise a particle size distribution of about 1 μm to about 1000 μm. The particle size of the nutritional powder is a significant factor determining the wettability and flow properties of the nutritional formula. The nutritional powder mean particle size may be measured by particle size analysis techniques that include, but are not limited to, laser diffraction, sieve separation analysis and image analysis (e.g., using a microscopic method such as light microscopy or scanning electron microscopy). The nutritional powder mean particle size may be from about 1 μm to about 1000 μm, about 10 μm to about 700 μm, about 20 μm to about 600 urn, about 30 μm to about 500 μm, about 40 μm to about 400 μm, about 30 μm to about 300 μm, about 60 μm to about 200 μm, about 80 μm to about 200 μm, or about 100 μm to about 190 μm. The nutritional powder mean particle size may be about 1 μm, S μm, 10 μm, 20 μm, 30 μm, 40 μm, 50 μm, 60 μm, 70 μm, 80 μm, 90 μm, 100 μm, 110 μm, 120 μm, 130 μm, 140 μm, 150 μm, 160 μm, 170 μm, 180 μm, 190 μm, 200 μm, 225 μm, 250 μm, 275 μm, 300 μm, 325 μm, 350 μm, 375 μm, 400 μm, 425 μm, 450 μm, 475 μm, 500 μm, 525 μm, 550 μm, 575 μm, 600 μm, 625 μm, 650 μm, 675 μm, 700 μm, 725 μm, 750 μm, 775 urn, 800 μm, 825 μm, 850 μm, 875 μm, 900 μm, 925 μm, 950 μm, 975 μm, or 1000 μm.

[0083] The nutritional powder may comprise particles of variable shapes. The shape of the particles differs from size of the particles by describing the external boundaries and surface of the particles. The shape and size of the nutritional composition particles can be used together to better characterize the nutritional powder. The shape of the nutritional powder is important in determining the wettability and flow properties of the formula. The nutritional powder particle shape and/or distribution of particle shapes may be determined by laser diffraction, and image analysis (e.g., using a microscopic method such as light microscopy or scanning electron microscopy). For example, size shape and morphology may be ascertained using a Malvern Morphologi G3, or other similar equipment used within the art. Using the above techniques it may be possible to determine statistical numbers for surface roughness, solidity and/or ruggedness. The aspect ratio (length divided by width), circularity, convexity, elongation, high sensitivity (HS) circularity, solidity fiber elongation, and fiber straightness can also be determined. The shape of the nutritional powder may be, but is not limited to, sphere, cube, plate, flake, rod or thread, or any combination thereof. In some embodiments, the nutritional powder may include irregularly shaped particles.

[0084] The nutritional powder may comprise particles of an aspect ratio of about 0.1 to about 1.0. The aspect ratio is a value which can aid in the analyzing the particle shapes comprised within the nutritional powder. The aspect ratio of the nutritional powder particles can affect the wettability and flow properties of the formula. The nutritional powder particle aspect ratio may be determined by laser diffraction, and image analysis. For example, particle aspect ratio may be ascertained using a Malvern Morphologi G3, or other similar equipment used within the art. The particles of the nutritional powder may have an aspect ratio of about 0.01, 0.03, 0.05, 0.07, 0.09, 0.11, 0.13, 0.15, 0.17, 0.19, 0.21, 0.23, 0.25, 0.27, 0.29, 0.31, 0.33, 0.35, 0.37, 0.39, 0.41, 0.43, 0.45, 0.47, 0.49, 0.51, 0.53, 0.55, 0.57, 0.59, 0.61, 0.63, 0.65, 0.67, 0.69, 0.71, 0.73, 0.75, 0.77, 0.79, 0.81, 0.83, 0.85, 0.87, 0.89, 0.91, 0.93, 0.95, 0.97, 0.99, or 1.

(3) Surface Area

[0087] The nutritional powder may comprise particles with a surface of about 0.02 m ² /g to about 3.0 m ² /g. The surface area of the particles within the nutritional powder is dependent on the size, shape and porosity of said particles, and is important in determining properties of the nutritional formula, such as dispersibility and rate of reconstitution. The particle porosity of the nutritional powder may be examined by the intrusion of a non-wetting liquid (e.g., mercury) at high pressure into the powder through the use of a porosimeter. The pore size can be determined based on the external pressure needed to force the liquid into a pore against the opposing force of the liquid's surface tension. The particles of the nutritional powder may have a surface area of about 0.02 m ² /g, 0.04 m ² /g, 0.06 m ² /g, 0.08 m ² /g, 0.10 m ² /g, 0.15 m ² /g, 0.20 m ² /g, 0.25 m ² /g, 0.30 m ² /g, 0.35 m ² /g, 0.40 m ² /g, 0.45 m ² /g, 0.50 m ² /g, 0.55 m ² /g, 0.60 m ² /g, 0.65 m ² /g, 0.70 m ² /g, 0.75 m ² /g, 0.80 m ² /g, 0.85 m ² /g, 0.90 m ² /g, 0.95 m ² /g, 1.0 m ² /g, 1.05 m ² /g, 1.1 m ² /g, 1.15 m ² /g, 1.2 m ² /g, 1.25 m ² /g, 1.3 m ² /g, 1.35 m ² /g, 1.4 m ² /g, 1.45 m ² /g, 1.5 m ² /g, 1.55 m ² /g, 1.6 m ² /g, 1.65 m ² /g, 1.7 m ² /g, 1.75 m ² /g, 1.8 m ² /g, 1.85 m ² /g, 1.9 m ² /g, 1.95 m ² /g, 2.0 m ² /g, 2.05 m ² /g, 2.1 m ² /g, 2.15 m ² /g, 2.2 m ² /g, 2.25 m ² /g, 2.3 m ² /g, 2.35 m ² /g, 2.4 m ² /g, 2.45 m ² /g, 2.5 m ² /g, 2.55 m ² /g, 2.6 m ² /g, 2.65 m ² /g, 2.7 m ² /g, 2.75 m ² /g, 2.8 m ² /g, 2.85 m ² /g, 2.9 m ² /g, 2.95 m ² /g, or 3.0 m ² /g.

[0088] The nutritional powder may comprise a glass transition temperature of about 30 °C to about 90 °C. The glass transition temperature of the nutritional powder describes the

liquification of said powder. Upon heating, the amorphous domain in a material will change from a glassy state to a rubbery state, while the crystalline domain will liquefy from a solid to a liquid. Glass transition analysis is useful as a comparison for a new product at standard moisture range. The glass transition temperature of a nutritional powder may be investigated via

Differential Scanning Calorimetry. The glass transition temperature of the nutritional powder may be about 30 °C, 31 °C, 32 °C, 33 °C, 34 °C, 35 °C, 36 °C, 37 °C, 38 °C, 39 °C, 40 °C, 41 °C, 42 °C, 43 °C, 44 °C, 45 °C, 46 °C, 47 °C, 48 °C, 49 °C, 50 °C, 51 °C, 52 °C, 53 °C, 54 °C, 55 °C, 56 °C, 57 °C, 58 °C, 59 °C, 60 °C, 61 °C, 62 °C, 63 °C, 64 °C, 65 °C, 66 °C, 67 °C, 68 °C, 69 °C, 70 °C, 71 °C, 72 °C, 73 °C, 74 °C, 75 °C, 76 °C, 77 °C, 78 °C, 79 °C, 80 °C, 81 °C, 82 °C, 83 °C, 84 °C, 85 °C, 86 °C, 87 °C, 88 °C, 89 °C, or 90 °C.

The melting temperature of the nutritional powder may be about 40 °C, 41 °C, 42 °C, 43 °C, 44 °C, 45 °C, 46 °C, 47 °C, 48 °C, 49 °C, 50 °C, 51 °C, 52 °C, 53 °C, 54 °C, 55 °C, 56 °C, 57 °C, 58 °C, 59 °C, 60 °C, 61 °C, 62 °C, 63 °C, 64 °C, 65 °C, 66 °C, 67 °C, 68 °C, 69 °C, 70 °C, 71 °C, 72 °C, 73 °C, 74 °C, 75 °C, 76 °C, 77 °C, 78 °C, 79 °C, 80 °C, 81 °C, 82 °C, 83 °C, 84 °C, 85 °C, 86 °C, 87 °C, 88 °C, 89 °C, 90 °C, 91 °C, 92 °C, 93 °C, 94 °C, 95 °C, 96 °C, 97 °C, 98 °C, 99 °C, or 100 °C.

(5) Flowability

[0090] The nutritional powder may comprise a flow factor of about 1 to about 10. The flowability of the nutritional powder is important in determining flow properties of the nutritional formula, such as rate of reconstitution and dispersibility. The flowability of the nutritional powder is a function of the nutritional powder particle characteristics, as well as the compounds within the powder, and is a measurement of the cohesion property of the nutritional powder. Flowability may be measured by a Brookfield powder flow tester, and is reported as a value of the flow factor and flow index. Flow factor is defined as the ratio of major principal consolidating stress (y-axis) to unconfined failure strength (x-axis) to 10 kPa to x-axis. Flow index is the inverse of flow factor. The flow factor of the nutritional powder may be about 1 to 10 or 1 to 8; for example, the flow factor may be about 1 , 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 5, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7, 5.8, 5.9, 6, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8, 6.9, 7, 7.1, 7.2, 7.3, 7.4, 7.5, 7.6, 7.7, 7.8, 7.9, 8, 8.1, 8.2, 8.3, 8.4, 8.5, 8.6, 8.7, 8.8, 8.9, 9, 9.1, 9.2, 9.3, 9.4, 9.5, 9.6, 9.7, 9.8, 9.9, or 10.

(6) Particle Porosity

[0091] The nutritional powder may comprise a particle porosity of about 5% to about 80%. The porosity of nutritional powder particles is important in determining the wettability and flow properties of the composition. The porosity of the nutritional powder particles may be measured by determining the volume of the open pores and interstitial void divided by the envelope powder volume, providing values in units of percent (from 0 - 100%). For example, the porosity of the nutritional powder particles may be about 5 to 80%, about 10% to about 80%, about 15% to about 80%, about 20% to about 80%, about 25% to about 80%, about 30% to about 80%, about 35%) to about 80%, or about 40% to about 75%. The porosity of the nutritional powder particles may be about 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, or 80%.

(7) Wettability

[0092] The nutritional powder may comprise a wettability of about 1 second to about 180 seconds, or about 1 second to about 30 seconds. The wettability of the nutritional powder is important on the overall flow performance of the nutritional formula through the nutrient delivery system. The wettability of the nutritional powder may be measured indirectly by adding a powder to the surface of water in a container (e.g., a beaker) and recording the time it takes for the powder to fall below the surface. The wettability may be about 1 second to about 20 seconds, or about 2 seconds to about 10 seconds. For example, the wettability may be about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, or 120 seconds.

(8) Free Fat

[0093] The nutritional powder may comprise free fat of about 0.1 g/100g powder to about 12 g/100g powder. High levels of free fat in the nutritional powder can be detrimental to the flowability of the powder, and potentially lead to difficulties in providing the nutritional formula. The free fat within the nutritional powder may be determined by performing a hexane (or other suitable non-polar solvents, for example, petroleum ether) extraction, followed by filtration (e.g., Whatman No. 41 filter paper) of the solvent extract (to remove suspended powder particles), drying oven evaporation of the solvent from the filtrate (e.g., at 60 fo°rC 2 hours) and weighing of the non- volatile residue (i.e., the extracted free fat) from the filtrate. The nutritional powder may comprise a free fat of about 0.1 g/100g powder, 0.3 g/100g powder, 0.5 g/100g powder, 0.7 g/100g powder, 0.9 g/100g powder, 1.1 g/100g powder, 1.3 g/100g powder, 1.5 g/100g powder, 1.7 g/100g powder, 1.9 g/100g powder, 2.1 g/100g powder, 2.3 g/100g powder, 2.5 g/100g powder, 2.7 g/100g powder, 2.9 g/100g powder, 3.1 g/100g powder, 3.3 g/100g powder, 3.5 g/100g powder, 3.7 g/100g powder, 3.9 g/100g powder, 4.1 g/100g powder, 4.3 g/100g powder, 4.5 g/100g powder, 4.7 g/100g powder, 4.9 g/100g powder, 5.1 g/100g powder, 5.3 g/100g powder, 5.5 g/100g powder, 5.7 g/100g powder, 5.9 g/100g powder, 6.1 g/100g powder, 6.3 g/100g powder, 6.5 g/100g powder, 6.7 g/100g powder, 6.9 g/100g powder, 7.1 g/100g powder, 7.3 g/100g powder, 7.5 g/100g powder, 7.7 g/100g powder, 7.9 g/100g powder, 8.1 g/100g powder, 8.3 g/100g powder, 8.5 g/100g powder, 8.7 g/100g powder, 8.9 g/100g powder, 9.1 g/100g powder, 9.3 g/100g powder, 9.5 g/100g powder, 9.7 g/100g powder, 9.9 g/100g powder, 10.1 g/100g powder, 10.3 g/100g powder, 10.5 g/100g powder, 10.7 g/100g powder, 10.9 g/100g powder, 11.1 g/100g powder, 11.3 g/100g powder, 11.5 g/100g powder, 11.7 g/100g powder, 11.9 g/100g powder, 12.1 g/100g powder, 12.3 g/100g powder, 12.5 g/100g powder, 12.7 g/100g powder, 12.9 g/100g powder, 13.1 g/100g powder, 13.3 g/100g powder, 13.5 g/100g powder, 13.7 g/100g powder, 13.9 g/100g powder, 14.1 g/100g powder, 14.3 g/100g powder, 14.5 g/100g powder, 14.7 g/100g powder, 14.9 g/100g powder, or 15 g/100g powder.

(9) Reconstitution

[0094] The nutritional powder may comprise a percent of reconstitution of about 75% to about 100%. The percent of reconstitution is important in determining the flow characteristics of the formula through the nutrient delivery system. The percent of reconstitution of the nutritional powder is dependent on properties of the nutritional powder such as, powder particle size, porosity and shape. The percent of reconstitution of the nutritional powder may be examined by measuring the percentage of the nutritional powder that is reconstituted when contacted by the liquid (e.g., does not remain in the pod following contact with the liquid, but is incorporated into the nutritional formula). The percent of reconstitution may be about 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100%.

[0095] The nutritional powder may be reconstituted in an amount of time from about 10 seconds to about 5 minutes. The reconstitution time is the time it takes for the 75% to 100% of the powder to be reconstituted to provide the nutritional formula, by the nutrient delivery system as described above. The reconstitution time is important in determining the flow characteristics of the formula through the nutrient delivery system. The reconstitution time is dependent on properties of the nutritional powder such as, powder particle size, porosity and shape. The reconstitution time may be determined by examining aliquots of the nutritional formula as it is produced by the nutrient delivery system (e.g., at intervals of time such as about every 5 seconds or about every 10 seconds), and calculating the total solids delivered over time using the interval samples. The reconstitution time may be about 10 seconds, 15 seconds, 20 seconds, 25 seconds, 30 seconds, 35 seconds, 40 seconds, 45 seconds, 50 seconds, 55 seconds, 1 minute, 1.5 minutes, 2 minutes, 2.5 minutes, 3 minutes, 3.5 minutes, 4 minutes, 4.5 minutes, 5 minutes, 5.5 minutes, 6 minutes, 6.5 minutes, 7 minutes, 7.5 minutes, 8 minutes, 8.5 minutes, 9 minutes, 9.5 minutes, or 10 minutes.

[00109] The protein may bind a mineral, for example, but not limited to, zinc and iron.

Accordingly, the protein may facilitate delivery of the mineral to the subject upon formation and subsequent ingestion of the nutritional formula by the subject. The protein may be present in the nutritional powder in any amount that allows the subject to make effective use of the mineral (e.g., zinc and iron) upon ingestion and digestion of the nutritional formula, which is described below in more detail. Effective use may include, but is not limited to, promoting uptake of the mineral by the subject.

[00110] In some embodiments, the protein may a protein that binds iron (e.g., pea protein), a protein that binds zinc (e.g., rice protein), or a combination of the protein that binds iron (e.g., pea protein) and the protein that binds zinc (e.g., rice protein). The protein may be pea protein, and thus, promotes the uptake of iron by the subject upon ingestion and digestion of the nutritional formula, which is described below in more detail, by the subject. The protein may be pea protein, and thus, facilitates delivery of iron to the subject upon formation and subsequent ingestion of the nutritional formula by the subject. The protein may be rice protein, and thus, promotes the uptake of zinc by the subject upon ingestion and digestion of the nutritional formula by the subject. The protein may be rice protein, and thus, facilitates delivery of zinc to the subject upon formation and subsequent ingestion of the nutritional formula by the subject. The protein may be a combination of pea protein and rice protein, and thus, promotes the uptake of iron and zinc by the subject upon ingestion and digestion of the nutritional formula by the subject. The protein may be a combination of pea protein and rice protein, and thus, facilitates delivery of iron and zinc to the subject upon formation and subsequent ingestion of the nutritional formula by the subject.

[00111] The protein may be a source of the one or more isoflavones, the one or more phytosterols, the one or more polyphenols, or any combination thereof. The one or more isoflavones, the one or more phytosterols, and the one or more polyphenols are described below in more detail.

[00112] The protein may also be a source of amino acids. The protein may be a source of essential amino acids. The protein may be a complete source of essential amino acids. The protein may be a source of amino acids such that essential amino acids do not need to be added individually to the nutritional powder. The protein may meet all of the requirements of the Food and Agriculture Organization (FAO), the Food and Nutrition Board (FNB), and/or the World Health Organization (WHO) in connection with the minimum amounts of indispensable amino acids for the subject. The protein may further be a source of one or more free amino acids that are antioxidants (e.g., tryptophan, cysteine, cystine, lysine, lysine acetate, histidine, tyrosine, valine, leucine, isoleucine, methionine, norleucine, phenylalanine, arginine, threonine, glutamic acid, proline, ornithine, aspartic acid, and serine).

[00113] The protein may be in the form of a hydrolysate, an isolate, a concentrate, or any combination thereof. In some embodiments, the protein may not be hydro lyzed (i.e., the protein is intact). In other embodiments, the protein may be hydrolyzed, for example, partially hydrolyzed. In still other embodiments, the protein may be a combination of intact protein (i.e., not hydrolyzed) and partially hydrolyzed protein.

[00114] As described in more detail below, modification (e.g., hydrolysis) of the protein may increase the solubility of the protein in the nutritional formula. The emulsion capacity of, the digestibility of, and the mineral delivery by the nutritional formula may increase with protein solubility. However, with increased hydrolysis, protein functionality and/or sensory qualities of the nutritional powder and/or nutritional formula are diminished, and therefore, as described in more detail below, a balance may be struck between these favorable and unfavorable features when hydrolyzing the protein.

(a) Pea Protein

[00115] The nutritional powder may include pea protein. The pea protein may be a source of amino acids such that essential amino acids do not need to be added individually to the nutritional powder. The pea protein may be intact pea protein or may be provided in a partially hydrolyzed form as described above. The pea protein may bind iron, thereby facilitating delivery of iron to the subject upon formation and subsequent ingestion of the nutritional formula. The pea protein may bind about 1 mg to about 200 mg iron per gram of pea protein such that the nutritional formula, which is described below in more detail, may deliver about 1 mg/100 kcal to about 5 mg/100 kcal iron to the subject.

[00116] In some embodiments, the pea protein may bind about 0.1 mg to about 200.0 mg, about 0.2 mg to about 200.0 mg, about 0.3 mg to about 200.0 mg, about 0.4 mg to about 200.0 mg, about 0.5 mg to

[00120] The pea protein may be derived from Pisum sativum. In other embodiments, the pea protein may be derived from other species of pea, including, but not limited to, green peas and field peas.

[00121] The pea protein may be in the form of a pea protein concentrate (PPC) or a pea protein isolate (PPI). PPC refers to concentrated pea protein sources containing 60 weight percent (wt. %) to 90 wt. % pea protein. PPI refers to a PPC which contains 80 wt. % to 90% pea protein.

[00122] One example of a suitable intact pea protein concentrate that may be included in the nutritional powder is the pea protein isolate based upon Pisum sativum available from Roquette Freres, Lestrem, France, and sold under the name NUTRALYS®F85F. This pea protein isolate has about 83 wt. % intact pea protein. Another example of an intact pea protein that may be included in the nutritional powder is the intact pea protein based on Pisum sativum available from Cosucra Groupe Warcoing of Warcoing, Belgium.

(b) Rice Protein

[00123] The nutritional powder may include rice protein. The rice protein may be intact rice protein or may be provided in a partially hydrolyzed form as described above. The rice protein may bind zinc, thereby facilitating delivery of zinc to the subject upon formation and subsequent ingestion of the nutritional formula. The rice protein may bind about 1 mg to about 170 mg zinc per gram of rice protein such that the nutritional formula may deliver about 0.5 mg/100 kcal to about 5 mg/100 kcal zinc to the subject.

[00124] In some embodiments, the rice protein may bind about 0.1 mg to about 200.0 mg, about 0.2 mg to about 200.0 mg, about 0.3 mg to about 200.0 mg, about 0.4 mg to about 200.0 mg, about 0.5 mg to

[00128] The rice protein may be derived from Asian rice (Oryza sativa), African rice (Oryza glabemma), or the combination thereof. The rice protein may be in the white rice form, the brown rice form, or the combination thereof. White rice is rice in which the hull, bran, and germ have all been removed from the rice. Brown rice, which is also known as "hulled" or "unmilled" rice, is whole grain rice, i.e., rice in which the hull has been removed, but the bran and germ have not been removed from the rice.

[00129] Brown rice protein may be in the form of brown rice protein concentrate, brown rice protein isolate, or the combination thereof. Commercial sources of brown rice protein that may be used in the nutritional powder may include, but are not limited to, the following

manufacturers: Nutribiotic, Jarrow Formulas, Vitacost, Sunwarrier, Axiom Foods, and AIDP.

[00130] In some embodiments, a source of intact brown rice protein that may be used in the nutritional powder is the brown rice protein powders sold under the name ORYZATEIN™ by Axiom Foods, Inc. of Los Angeles, California and distributed by Prinova, USA of Carol Stream, Illinois.

[00131] White rice protein, like brown rice protein, may be in the form of a protein

concentrate, a protein isolate, or the combination thereof. A commercial source of white rice protein concentrate and white rice protein isolate includes, but is not limited to, the white rice protein products sold under the name Gabioten by Shanghai Freemen Chemicals Company, LLC. of Shanghai, China.

(c) Potato Protein

[00132] The nutritional powder may include potato protein. The potato protein may be intact potato protein or may be provided in a partially hydrolyzed form as described above.

[00133] The potato protein may be in the form of a concentrate, an isolate, or the combination thereof. The potato protein may be in the form of a concentrate or isolate that contains 80% to 95% protein and available from Solanic, which is a subsidiary of AVEBE of Veedam, The Netherlands.

(d) Soy Protein

[00134] The nutritional powder may include soy protein. The soy protein may be intact soy protein or may be provided in a partially hydrolyzed form as described above.

[00135] The soy protein may be in the form of a concentrate, an isolate, or the combination thereof. A soy protein concentrate (SPC) refers to products which are basically soybean without the water soluble carbohydrates and which contain about 60 wt.% to about 90 wt.% or more soy protein. In some embodiments, the SPC contains about 60 wt.% to about 85 wt.% soy protein or about 70 wt. % to about 80 wt.% soy protein. A soy protein isolate (SPI) refers to a type of SPC that contains about 85 wt.% to about 90 wt.% soy protein. SPI is the most refined form of soy protein.

[00136] Commercial sources of soy protein include, but are not limited to, The Solae Company of St. Louis, Mo., USA, and the Arthur Daniels Midland Company of Decatur, Illinois, USA.

(e) Hemp Protein

[00137] The nutritional powder may include hemp protein. The hemp protein may be intact hemp protein or may be provided in a partially hydrolyzed form as described above.

[00138] The hemp protein may be in the form of a concentrate, an isolate, or the combination thereof. The hemp protein may be in the form of a concentrate or isolate.

(f) Protein Modification

[00139] The protein contained in the nutritional powder may be modified, for example, hydrolyzed. The protein may be partially hydrolyzed.

[00140] The degree of hydrolysis is the extent to which peptide bonds are broken by a hydrolysis chemical or enzymatic reaction. To quantify the partially hydrolyzed protein component of the nutritional powder, the degree of protein hydrolysis is determined by quantifying the amino nitrogen to total nitrogen ratio (AN/TN) of the protein component of the selected nutritional powder. The amino nitrogen component is quantified by USP titration methods for determining amino nitrogen content, while the total nitrogen component is determined by the Tecator® Kjeldahl method. Accordingly, another way of referring to the extent of hydro lyzation in hydrolyzed protein is by degree of hydrolysis (DH). A DH value of, for example, 30 refers to protein in which 30% of the total protein is hydrolyzed.

[00141] In some embodiments, the protein may have a degree of hydrolysis (DH) of about 0 to about 60, about 1 to about 60, about 2 to about 60, about 3 to about 60, about 4 to about 60, about 5 to about 60, about 6 to about 60, about 7 to about 60, about 8 to about 60, about 9 to about 60, about 10 to about 60, about 15 to about 60, about 20 to about 60, about 25 to about 60, about 30 to about 60, about 35 to about 60, about 40 to about 60, about 45 to about 60, about 50 to about 60, about 55 to about 60, about 0 to about 55, about 0 to about 50, about 0 to about 45, about 0 to about 40, about 0 to about 35, about 0 to about 30, about 0 to about 25, about 0 to about 20, about 0 to about 15, about 0 to about 10, about 0 to about 9, about 0 to about 8, about 0 to about 7, about 0 to about 6, about 0 to about 5, about 1 to about 55, about 2 to about 50, about 3 to about 45, about 4 to about 40, about 5 to about 35, about 6 to about 30, about 7 to about 25, about 8 to about 20, about 9 to about 15, or about 0, about 1, about 2, about 3, about 4, about 5, about 6, about 7, about 8, about 9, about 10, about 11, about 12, about 13, about 14, about 15, about 16, about 17, about 18, about 19, about 20, about 21, about 22, about 23, about 24, about 25, about 26, about 27, about 28, about 29, about 30, about 31, about 32, about 33, about 34, about 35, about 36, about 37, about 38, about 39, about 40, about 41, about 42, about 43, about 44, about 45, about 46, about 47, about 48, about 49, about 50, about 51, about 52, about 53, about 54, about 55, about 56, about 57, about 58, about 59, or about 60.

[00142] In some embodiments, the protein may be substantially free of any protein that has a degree of hydrolysis of 61 or more. In other embodiments, the partially hydro lyzed protein may be protein having a degree of hydrolysis (DH) of less than about 61, less than about 60, less than about 55, less than about 50, less than about 45, less than about 40, less than about 35, less than about 30, less than about 25, less than about 20, less than about 15, less than about 10, or less than about 5. In other embodiments, the partially hydro lyzed protein may be protein having a degree of hydrolysis of less than about 61, 60, 59, 58, 57, 56, 55, 54, 53, 52, 51, 50, 49, 48, 47, 46, 45, 44, 43, 42, 41, 40, 39, 38, 37, 36, 35, 34, 33, 32, 31, 30, 29, 28, 27, 26, 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1.

[00143] Hydrolysis of the protein that is contained within the nutritional powder may increase the solubility of the protein in the nutritional formula. Soluble protein is protein that does not precipitate (i.e., resides in the supernatant) when a 2% (w/w) suspension of the total protein in water is centrifuged at 31,000 x g at 20 degrees Celsius for sixty minutes. In some embodiments, protein solubility may increase as DH increases.

[00144] The following favorable features of the protein may increase with solubility: emulsion capacity, digestibility, and mineral delivery. In turn, the following unfavorable features of the protein may increase with the degree of hydrolysis: compromised sensory quality (i.e., deteriorating sensory attributes, which are described below in more detail) and poor protein functionality. Accordingly, a balance may exist between solubility and degree of hydrolysis of the protein with regards to increasing favorable features of the protein and decreasing unfavorable features of the protein.

[00145] In some embodiments, when the protein has been modified to have a relatively high solubility and a relatively low degree of hydrolysis, an acceptable balance may be struck between the favorable (e.g., emulsion capacity, digestibility, and mineral delivery) and unfavorable (e.g., compromised sensory quality and poor functionality) features of the protein. This balance may be represented by the value R, which is a ratio of soluble protein (expressed as % of total protein) to the degree of hydrolysis ("DH," expressed as %). In some embodiments, a value of R greater than about 10, greater than about 12, or greater than about 15 may provide an acceptable balance between favorable and unfavorable features of the protein. In other embodiments, the protein may be modified such that R is between about 10 and about 30, about 12 and about 25, or about 15 and about 20. In still other embodiments, the protein may be modified such that R is about 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30.

[00146] The protein may be hydrolyzed enzymatically. The enzyme may be, but is not limited to, plant proteases (e.g., bromelain, papain), animal proteases (e.g., pancreatin, trypsin), and bacterial proteases (e.g., pronase E). Hydrolysis may be controlled, for example, through temperature, time, pH, and enzyme/substrate ratio to yield the desired value of R. The soluble protein concentration and the degree of hydrolysis may be measured by any suitable method, including the chromatographic method (as described in Food. Chem., 125 [2011] 1041-1050, the entire disclosure of which is incorporated herein by reference).

(b) Fat or Oil

[00147] The nutritional powder may also include the fat, which may be in the form of oil.

[00182] The container body is molded or otherwise constructed of a food-safe plastic material, such as polypropylene or polyethylene. The lid can be made of a polymer film, metal foil, or any other material suitable for affixing to the flange. At least one of the lid and the container body is configured to receive an injector or similar device through which water, air, or other fluids may be introduced to facilitate mixing and reconstitution within the enclosed volume. The introduced fluid(s) may be pre-filtered or alternatively pass through a filtration unit disposed within the container. An outlet member integrally formed as part of or movably coupled to the container body is positioned for dispensing from the pod, with the assistance of the introduced fluid(s), a nutritional product incorporating the powder or liquid concentrate. The dispensed product volume can range from approximately 5 mL to approximately 1000 mL, for example from approximately 20 mL to approximately 750 mL, from approximately 50 mL to approximately 500 mL, and is preferably between approximately 70 mL and approximately 250 mL. For example, the dispensed product volume may be approximately 5 mL, 10 mL, 15 mL, 20 mL, 25 mL, 30 mL, 35 mL, 40 mL, 45 mL, 50 mL, 55 mL, 60 mL, 65 mL, 70 mL, 75 mL, 80 mL, 85 mL, 90 mL, 95 mL, 100 mL, 105 mL, 110 mL, 115 mL, 120 mL, 125 mL, 130 mL, 135 mL, 140 mL, 145 mL, 150 mL, 155 mL, 160 mL, 165 mL, 170 mL, 175 mL, 180 mL, 185 mL, 190 mL, 195 mL, 200 mL, 205 mL, 210 mL, 215 mL, 220 mL, 225 mL, 230 mL, 235 mL, 240 mL, 245 mL, 250 mL, 255 mL, 260 mL, 265 mL, 270 mL, 275 mL, 280 mL, 290 mL, 300 mL, 305 mL, 310 mL, 315 mL, 320 mL, 325 mL, 330 mL, 335 mL, 340 mL, 345 mL, 350 mL, 355 mL, 360 mL, 365 mL, 370 mL, 375 mL, 380 mL, 385 mL, 390 mL, 395 mL, 400 mL, 405 mL, 410 mL, 415 mL, 420 mL, 425 mL, 430 mL, 435 mL, 440 mL, 445 mL, 450 mL, 455 mL, 460 mL, 465 mL, 470 mL, 475 mL, 480 mL, 490 mL, 500 mL, 505 mL, 510 mL, 515 mL, 520 mL, 525 mL, 530 mL, 535 mL, 540 mL, 545 mL, 550 mL, 555 mL, 560 mL, 565 mL, 570 mL, 575 mL, 580 mL, 585 mL, 590 mL, 595 mL, 600 mL, 605 mL, 610 mL, 615 mL, 620 mL, 625 mL, 630 mL, 635 mL, 640 mL, 645 mL, 650 mL, 655 mL, 660 mL, 665 mL, 670 mL, 675 mL, 680 mL, 690 mL, 700 mL, 705 mL, 710 mL, 715 mL, 720 mL, 725 mL, 730 mL, 735 mL, 740 mL, 745 mL, 750 mL, 755 mL, 760 mL, 765 mL, 770 mL, 775 mL, 780 mL, 785 mL, 790 mL, 795 mL, 800 mL, 805 mL, 810 mL, 815 mL, 820 mL, 825 mL, 830 mL, 835 mL, 840 mL, 845 mL, 850 mL, 855 mL, 860 mL, 865 mL, 870 mL, 875 mL, 880 mL, 890 mL, 900 mL, 905 mL, 910 mL, 915 mL, 920 mL, 925 mL, 930 mL, 935 mL, 940 mL, 945 mL, 950 mL, 955 mL, 960 mL, 965 mL, 970 mL, 975 mL, 980 mL, 985 mL, 990 mL, 995 mL, or 1000 mL. The temperature of the dispensed nutritional product is product dependent and can range from approximately 5° C to approximately 60°C, or from approximately 25°C to about 50 °C. For example, the

temperature may be approximately 5°C , 6 °C, 7 °C, 8 °C, 9 °C, 10 °C, 11 °C, 12 °C, 13 °C, 14 °C, 15°C , 16 °C, 17 °C, 18 °C, 19 °C, 20 °C, 21 °C, 22 °C, 23 °C, 24°C , 25 °C, 26 °C, 27 °C, 28°C , 29°C , 30 °C, 31 °C, 32 °C, 33 °C, 34°C, 35°C , 36 °C, 37 °C, 38 °C, 39 °C, 40°C, 41 °C, 42°C , 43 °C, 44°C, 45°C , 46 °C, 47 °C, 48 °C, 49 °C, 50°C, 51 °C , 52 °C, 53 °C, 54 °C, 55°C , 56°C , 57 °C, 58 °C, 59 °C, or 60°C . c. Nutritional Formula

[00183] As discussed above, the nutrient delivery system may comprise a nutritional powder that is within a pod. The nutrient delivery system delivers water at a particular temperature to the nutritional powder within the pod, and provides a nutritional formula. The nutritional formula is delivered from the pod to a receptacle such as a cup or baby bottle. The physical characteristics that are important for the overall function of the nutritional formula include the powder reconstitution characteristics (e.g., wettability), viscosity, foaming, emulsion stability, amino acid profile, mineral delivery, antioxidant capacity, shelf-life stability, odor, flavor, and digestibility.

[00184] The nutritional powder, as described above, includes protein. The protein may bind a mineral, for example, such as, but not limited to, zinc and iron, such that upon ingestion of the nutritional formula by the subject, the mineral is delivered to the subject. The protein may also lend the nutritional formula improved digestibility relative to a nutritional formula that does not contain the protein in the amounts described above. In particular, digestibility may be improved when the protein has a degree of hydrolysis of about 0 to about 60. A degree of hydrolysis of about 0 to about 60 may also increase the solubility of the protein in the nutritional formula, which in turn, may increase the emulsion capacity of and mineral delivery by the nutritional formula. This degree of hydrolysis of about 0 to about 60 may not introduce detrimental features into the nutritional formula such as compromised sensory quality and decreased protein functionality.

[00185] Additionally, as described above in more detail, the protein may be a source of one or more isoflavones, one or more phytosterols, one or more polyphenols, or any combination thereof. The one or more isoflavones may provide antioxidant activity, cholesterol lowering activity, radical scavenging, and/or cytoprotection. The one or more phytosterols may reduce serum or plasma total cholesterol and/or low density lipoprotein (LDL) levels in the subject after ingestion and digestion of the nutritional formula by the subject. The one or more phytosterols may exhibit one or more anti-tumor properties in the subject after ingestion and digestion of the nutritional formula.

[00186] As described above in more detail, an additional source of the one or more

isoflavones, the one or more phytosterols, and the one or more polyphenols may be a fat such as oil and thus, the nutritional powder may also include oil as described above in more detail.

(1) Viscosity

[00187] The nutritional formula may comprise a viscosity of about 0.8 to about 30 cPs.

Viscosity is the measurement of resistance to gradual deformation by shear or tensile stress. The nutritional formula's viscosity may be dependent on the components that are comprised within the nutritional composition. The viscosity of the nutritional formula is important on the overall flow performance of the nutritional formula through the nutrient delivery system. The viscosity of the nutritional formula may be measured by a rheometer, which may be used to measure how a liquid, slurry, or suspension flows in response to applied forces. The rheometer may be a shear/rotational rheometer or an extensional rheometer. The shear/rotational rheometer may be a pipe/capillary rheometer, cone and plate rheometer, or linear shear rheometer. The extensional rheometer may be an acoustic rheometer, falling plate rheometer, or capillary/contraction flow rheometer. The viscosity of the nutritional formula may be about 0.8 to 30 cPs, about 0.8 to 10 cPs, about 1 to 9 cPs, or about 2 to 6 cPs. The viscosity of the nutritional formula may be less than lcPs, less than 2 cPs, less than 3 cPs, less than 4 cPs, less than 5 cPs, less than 6 cPs, less than 7 cPs, less than 8 cPs, less than 9 cPs, less than 10 cPs, less than 11 cPs, less than 12 cPs, less than 13 cPs, less than 14 cPs, less than 15 cPs, less than 16 cPs, less than 17 cPs, less than 18 cPs, less than 19 cPs, less than 20 cPs, less than 21 cPs, less than 22 cPs, less than 23 cPs, less than 24 cPs, less than 25 cPs, less than 26 cPs, less than 27 cPs, less than 28 cPs, less than 29 cPs, less than 30 cps, about 0.8 cPs, about 0.9 cPs, about 1 cPs, about 2 cPs, about 3 cPs, about 4 cPs, about 5 cPs, about 6 cPs, about 7 cPs, about 8 cPs, about 9 cPs, about 10 cPs, about 11 cPs, about 12 cPs, about 13 cPs, about 14 cPs, about 15 cPs, about 16 cPs, about 17 cPs, about 18 cPs, about 19 cPs, about 20 cPs, about 21 cPs, about 22 cPs, about 23 cPs, about 24 cPs, about 25 cPs, about 26 cPs, about 27 cPs, about 28 cPs, about 29 cPs, or about 30 cPs.

(2) Density

[00188] [0084] The nutritional formula may comprise a density between about 0.90 g/cm ³ and about 1.2 g/cm ³ . The density of the nutritional formula is a function of the amount of entrapped air is present within the formula, among other factor, such as the compounds within the nutritional formula. The density of the nutritional formula is important in determining the flow characteristics of the formula, as well as well as side-effects associated with consumption of the formula (e.g., gassiness). The density of the nutritional formula may be about0.90 g/cm ³ , 0.91 g/cm ³ , 0.92 g/cm ³ , 0.93 g/cm ³ , 0.94 g/cm ³ , 0.95 g/cm ³ , 0.96 g/cm ³ , 0.97 g/cm ³ , 0.98 g/cm ³ , 0.99 g/cm ³ , 1.00 g/cm ³ , 1.01 g/cm ³ , 1.02 g/cm ³ , 1.03 g/cm ³ , 1.04 g/cm ³ , 1.05 g/cm ³ , 1.06 g/cm ³ , 1.07 g/cm ³ , 1.08 g/cm ³ , 1.09 g/cm ³ , 1.10 g/cm ³ , 1.11 g/cm ³ , 1.12 g/cm ³ , 1.13 g/cm ³ , 1.14 g/cm ³ , 1.15 g/cm ³ , 1.16 g/cm ³ , 1.17 g/cm ³ , 1.18 g/cm ³ , 1.19 g/cm ³ , or 1.20 g/cm ³ .

The Hunter Lab "b" value of the nutritional formula may be about 1.00, 2.00, 3.00, 4.00, 5.00, 6.00, 7.00, 8.00, 9.00, 10.00, 11.00, 12.00, 13.00, 13.10, 13.20, 13.30, 13.31, 13.32, 13.33, 13.34, 13.35, 13.36, 13.37, 13.38, 13.39, 13.40, 13.41, 13.42, 13.43, 13.44, 13.45, 13.46, 13.47, 13.48, 13.49, 13.50, 13.51, 13.52, 13.53, 13.54, 13.55, 13.56, 13.57, 13.58, 13.59, 13.60, 13.61, 13.62, 13.63, 13.64, 13.65, 13.66, 13.67, 13.68, 13.69, 13.70, 13.71, 13.72, 13.73, 13.74, 13.75, 13.76, 13.77, 13.78, 13.79, 13.80, 13.81, 13.82, 13.83, 13.84, 13.85, 13.86, 13.87, 13.88, 13.89, 13.90, 13.91, 13.92, 13.93, 13.94, 13.95, 13.96, 13.97, 13.98, 13.99, 14.00, 15.00, 16.00, 17.00, 18.00, 19.00, 20.00, 25.00, or 30.00.

(4) Caloric Density

[00192] The nutritional formula produced by the nutrient delivery system may comprise a caloric density of about 65 kcal/240 mL to about 800 kcal/240mL. The nutritional formula, as discussed herein, provides a method to easily and effectively control caloric intake to an individual (e.g., infant). The ability to tightly control caloric intake is important because different individuals have different caloric needs. The nutritional formula produced by the nutrient delivery system may comprise a caloric density of about 65 kcal/240 mL, 70 kcal/240 mL, 75 kcal/240 mL, 80 kcal/240 mL, 85 kcal/240 mL, 90 kcal/240 mL, 95 kcal/240 mL, 100 kcal/240 mL, 105 kcal/240 mL, 110 kcal/240

kcal/240 mL, 130 kcal/240 mL, 135 kcal/240

kcal/240 mL, 155 kcal/240 mL, 160 kcal/240 mL, 165 kcal/240 mL, 170 kcal/240 mL, 175 kcal/240 mL, 180 kcal/240 mL, 185 kcal/240 mL, 190 kcal/240 mL, 195 kcal/240 mL, 200 kcal/240 mL, 205 kcal/240 mL, 210 kcal/240 mL, 215 kcal/240 mL, 220 kcal/240 mL, 225 kcal/240 mL, 230 kcal/240 mL, 235 kcal/240 mL, 240 kcal/240 mL, 245 kcal/240 mL, 250 kcal/240 mL, 255 kcal/240 mL, 260 kcal/240 mL, 265 kcal/240 mL, 270 kcal/240 mL, 275 kcal/240 mL, 280 kcal/240 mL, 285 kcal/240 mL, 290 kcal/240 mL, 295 kcal/240 mL, 300 kcal/240 mL, 305 kcal/240 mL, 310 kcal/240 mL, 315 kcal/240 mL, 320 kcal/240 mL, 325 kcal/240 mL, 330 kcal/240 mL, 335 kcal/240 mL, 340 kcal/240 mL, 345 kcal/240 mL, 350 kcal/240 mL, 355 kcal/240 mL, 360 kcal/240 mL, 365 kcal/240 mL, 370 kcal/240 mL, 375 kcal/240 mL, 380 kcal/240 mL, 385 kcal/240 mL, 390 kcal/240 mL, 395 kcal/240 mL, 400 kcal/240 mL, 405 kcal/240 mL, 410 kcal/240 mL, 415 kcal/240 mL, 420 kcal/240 mL, 425 kcal/240 mL, 430 kcal/240 mL, 435 kcal/240 mL, 440 kcal/240 mL, 445 kcal/240 mL, 450 kcal/240 mL, 455 kcal/240 mL, 460 kcal/240 mL, 465 kcal/240 mL, 470 kcal/240 mL, 475 kcal/240 mL, 480 kcal/240 mL, 485 kcal/240 mL, 490 kcal/240 mL, 495 kcal/240 mL, 500 kcal/240 mL, 550 kcal/240 mL, 600 kcal/240 mL, 650 kcal/240 mL, 700 kcal/240 mL, 750 kcal/240 mL, or 800 kcal/240 mL.

(5) Dispersibility

[00193] The nutritional formula may comprise a qualitative dispersibility of about 1 to about 4. Dispersibility is way of determining the degree of firmness and solubility of particles within a product. Dispersibility is important in determining flow characteristics of the nutritional formula. Dispersibility is measured as how well the product will pass through the nipple of an infant bottle. For example, in a qualitative assay, an 8 ounce bottle may be prepared and shaken for 10 seconds. The product is then passed through an 80 mesh sieve and scored based on the number of remaining particles. The nutritional formula may comprise a dispersibility of about 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, or 4.0. In a quantitative assay, the product is passed through an 80 mesh sieve as described above, and the total number of particles present on the sieve is measured using a mm stick and /or ruler. The size of the particles are then stratified into groups consisting of less than 1 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm and greater than 5 mm.

(6) Foaming

[00194] The nutritional formula may comprise a foaming volume of about 1 mL to about 70 mL, about 1 mL to about 30 mL, or about 1 mL to about 20 mL. Foaming of the nutritional formula can be attributed to the presence of entrapped air after the nutrient delivery system provides the nutritional formula, which is dependent on at least the compounds within the nutritional powder. Decreased foaming is a desired property of the nutritional formula because excess foam may increase potential side-effects that can be associated with consumption of the nutritional formula (e.g., gassiness, bloating, etc.). The foaming volume of the nutritional formula may be measured by a graduated cylinder after being provided by the nutrient delivery system. Additionally the foaming value may be measured at variable time points after initial addition to the graduated cylinder (e.g., 1 minute, 2 minutes, 3 minutes, 4 minutes, 5 minutes, 10 minutes, 15 minutes, or 30 minutes after the nutritional formula has been added to the

graduated). The foaming volume may be about 1 mL, 2 mL, 3 mL, 4 mL, 5 mL, 6 mL, 7 mL, 8 mL, 9 mL, 10 mL, 11 mL, 12 mL, 13 mL, 14 mL, 15 mL, 16 mL, 17 mL, 18 mL, 19 mL, 20 mL, 21 mL, 22 mL, 23 mL, 24 mL, 25 mL, 26 mL, 27 mL, 28 mL, 29 mL, 30 mL, 31 mL, 32 mL, 33 mL, 34 mL, 35 mL, 36 mL, 37 mL, 38 mL, 39 mL, 40 mL, 41 mL, 42 mL, 43 mL, 44 mL, 45 mL, 46 mL, 47 mL, 48 mL, 49 mL, 50 mL, 51 mL, 52 mL, 53 mL, 54 mL, 55 mL, 56 mL, 57 mL, 58 mL, 59 mL, 60 mL, 61 mL, 62 mL, 63 mL, 64 mL, 65 mL, 66 mL, 67 mL, 68 mL, 69 mL, or 70 mL.

[00195] The nutritional formula may comprise a foaming ratio of about 1 to about 15. The foaming ratio of the nutritional formula is investigated by measuring the volume of foam within a graduated cylinder after being provided by the nutrient delivery system and at variable time points after initial addition to the graduated cylinder (e.g., 1 minute, 2 minutes, 3 minutes, 4 minutes, 5 minutes, 10 minutes, 15 minutes, or 30 minutes after the nutritional formula has been added to the graduated cylinder). The ratio of foaming level at time 0 and the variable time points are then measured for the sample. The foaming ratio of the nutritional formula may be about 1.0, 1.2, 1.4, 1.6, 1.8, 2.0, 2.2, 2.4, 2.6, 2.8, 3.0, 3.2, 3.4, 3.6, 3.8, 4.0, 4.2, 4.4, 4.6, 4.8, 5.0, 5.2, 5.4, 5.6, 5.8, 6.0, 6.2, 6.4, 6.6, 6.8, 7.0, 7.2, 7.4, 7.6, 7.8, 8.0, 8.2, 8.4, 8.6, 8.8, 9.0, 9.2, 9.4, 9.6, 9.8, 10, 10.2, 10.4, 10.6, 10.8, 11, 11.2, 11.4, 11.6, 11.8, 12, 12.2, 12.4, 12.6, 12.8, 13, 13.2, 13.4, 13.6, 13.8, 14, 14.2, 14.4, 14.6, 14.8, or 15. d. Special Properties

[00196] The nutrient delivery system comprises the nutritional powder and provides the nutritional formula as described above. The nutritional powder and the nutritional formula may be assayed for various properties for quality assurance. One such property is sensory

information, including smell and taste. Another such property is browning, which can provide an unpleasant appearance and which can decrease the value of a nutritional composition.

Additional properties are protein digestibility of the nutritional formula and an amount of soluble protein in the nutritional powder.

(1) Sensory Analysis

[00197] Sensory tests provide useful information because they relate to the consumer acceptance of the food based on smell and taste. The method is very sensitive and provides information on flavor stability. All samples are evaluated by a trained taste panel to determine bitterness, sweetness, and fishiness of the samples. The sensory analysis is performed using a scale of 0 to 7, with 7 being the strongest sensation/flavor and 0 being the lowest. As such, lower values indicate less bitterness, sweetness and fishiness. The nutritional powder and nutritional formula may be evaluated at various time intervals. The nutritional powder and nutritional formula may also be evaluated for a beany off note.

[00198] The nutritional powder may have a bitterness score of less than 7, less than 6.5, less than 6, less than 5.5, less than 5, less than 4.5, less than 4, less than 3.5, less than 3, less than 2.5, less than 2, less than 1.5, less than 1, or less than 0.5.

[00204] The one or more isoflavones described above may lend a beany off note to the nutritional powder and/or the nutritional formula. (2) Browning

[00205] The nutritional powder, and the nutritional formula provided by the nutrient delivery system, include a hydrolyzed protein and a masking agent. In some embodiments, the inclusion of a hydrolyzed protein and certain masking agents such as reducing sugars can lead to browning. Browning is the process of becoming brown, especially referring to food. Browning of the nutritional powder of the present invention is undesirable. Browning has an economic cost, causing deterioration of the value of products in the market of food. The nutritional powder and nutritional formulation may therefore include a compound that may inhibit browning, or may include ratios of components that are selected to minimize browning. Examples of methods used to inhibit browning include, but are not limited to, substituting a non-reducing sugar (e.g., sucrose) for a reducing sugar (e.g., lactose), substituting a low DE maltodextrin (e.g., Maltrin 40) for a high DE maltodextrin (e.g., Maltrin 200), substituting a low DH protein ingredient (e.g., DH 10%) for a high DH protein ingredient (e.g., DH 30%), decreasing the concentration of free amino acids, by decreasing the concentration of protein-bound lysine, lowering the pH, substituting sodium ascorbate for ascorbic acid, and/or substituting an iron amino acid chelate for ferrous sulfate.

[00206] Foods can turn brown through either enzymatic or non-enzymatic processes.

Enzymatic browning is a chemical process, involving polyphenol oxidase, catechol oxidase, and other enzymes that create melanins and benzoquinone from natural phenols, resulting in a brown color. In general, enzymatic browning requires exposure to oxygen, for example the browning that occurs when an apple is cut.

[00207] Non-enzymatic browning is a chemical process that produces a brown color in foods without the activity of enzymes. The two main forms of nonenzymatic browning are

caramelization and the Maillard reaction. The Maillard reaction is a chemical reaction between an amino acid and a reducing sugar, usually requiring the addition of heat. The sugar interacts with the amino acid, producing a variety of odors and flavors. When protein hydro lysates are the protein source it is preferable to avoid conditions which could lead to the formation of excessive Maillard browning products.

[00208] The Maillard reaction is affected by the concentration of the initial reactant species, pH, water content, and presence of substances such as humectants and bisulfite. Some physical factors, such as processing and storage temperature, atmospheric oxygen, and packaging during storage can also affect the Maillard reaction in foods. The deleterious effects of nonenzymatic browning include: decreased nutritional value from protein loss, off-flavor development, undesirable color, decreased solubility, texture changes, destruction of vitamins, and increased acidity.

[00209] The rate of deterioration of nutritional powders and/or formulations containing hydrolyzed proteins may be determined under accelerated storage conditions through the use of the Arrhenius equation with extrapolation. The accelerated shelf life testing (ASLT) data may be compared with Maillard browning occurring under normal storage conditions (21°C, 35% RH). The rate of deterioration by browning of the nutritional powder and/or nutritional formula samples may be compared with changes in microbiological, physicochemical, and sensory quality during storage to establish the keeping quality of the nutritional powders and nutritional formulas.

[00210] Microbiological and physicochemical changes of the nutritional powder and nutritional formula are determined, in part, by the color change of the nutritional powder and nutritional formula. Determination and quantification of the color change of the nutritional powder may be achieved with Hunter Laboratory values L* (lightness-darkness parameter), a* (redness-greenness parameter), and b* (yellowness-blueness parameter). In particular, L* and a* have been shown to provide optimal sensitivity for detecting changes in samples containing hydrolyzed proteins.

[00211] The nutritional powder and nutritional formula may comprise Hunter Lab "L", "a", and "b" values. The Hunter Lab "L", "a", and "b" values of the nutritional powder can be measured by a spectrophotometer, which allows quantitative measurement of the reflection or transmission properties of the formula as a function of wavelength. The Hunter Lab "L", "a", and "b" values of the nutritional powder may be the values as disclosed below for the nutritional formula.

(3) Protein Digestibility

[00212] The nutritional powder, and the nutritional formula provided by the nutrient delivery system, include a hydrolyzed protein. In some embodiments, the extent of protein hydrolysis can be determined by performing selected analyses after an in vitro gastrointestinal digestion. For example, a nutritional formula can be treated with one or more digestive enzymes (e.g., pepsin, pancreatin amylase, pancreatin protease and/or pancreatin lipase). The digested formula can be centrifuged (e.g., using high-speed centrifugation), and the supernatant analyzed for its molecular weight profile using HPLC. The pellet can be tested for any insoluble proteins, using acid hydrolysis followed by an analysis of the amino acid profile.

[00213] The analysis may indicate that the nutritional formula includes a protein median molecular weight of about 700 Da to about 1100 Da. For example, the protein median molecular weight in the nutritional formula may be about 700 Da, 710 Da, 720 Da, 730 Da, 740 Da, 750 Da, 760 Da, 770 Da, 780 Da, 790 Da, 800 Da, 810 Da, 820 Da, 830 Da, 840 Da, 850 Da, 860 Da, 870 Da, 880 Da, 890 Da, 900 Da, 910 Da, 920 Da, 930 Da, 940 Da, 950 Da, 960 Da, 970 Da, 980 Da, 990 Da, 1000 Da, 1010 Da, 1020 Da, 1030 Da, 1040 Da, 1050 Da, 1060 Da, 1070 Da, 1080 Da, 1090 Da, or 1100 Da.

[00214] The analysis may indicate that the nutritional formula includes proteins having a molecular weight of greater than 5000 Da, as a percentage of total protein, of about 3% to about 10%. For example, the percentage of proteins having a molecular weight of greater than 5000 Da may be about 3.0%, 3.1%, 3.2%, 3.3%, 3.4%, 3.5%, 3.6%, 3.7%, 3.8%, 3.9%, 4.0%, 4.1%, 4.2%, 4.3%, 4.4%, 4.5%, 4.6%, 4.7%, 4.8%, 4.9%, 5.0%, 5.1%, 5.2%, 5.3%, 5.4%, 5.5%, 5.6%, 5.7%, 5.8%, 5.9%, 6.0%, 6.1%, 6.2%, 6.3%, 6.4%, 6.5%, 6.6%, 6.7%, 6.8%, 6.9%, 7.0%, 7.1%, 7.2%, 7.3%, 7.4%, 7.5%, 7.6%, 7.7%, 7.8%, 7.9%, 8.0%, 8.1%, 8.2%, 8.3%, 8.4%, 8.5%, 8.6%, 8.7%, 8.8%, 8.9%, 9.0%, 9.1%, 9.2%, 9.3%, 9.4%, 9.5%, 9.6%, 9.7%, 9.8%, 9.9%, or 10% as a percentage of total protein.

[00215] The analysis may indicate that the nutritional formula includes insoluble protein in an amount of about 1 mg/L to about 600 mg/L. For example, the nutritional formula many include insoluble proteins in an amount of about 1 mg/L, 2 mg/L, 3 mg/L, 4 mg/L, 5 mg/L, 6 mg/L, 7 mg/L, 8 mg/L, 9 mg/L, 10 mg/L, 20 mg/L, 30 mg/L, 40 mg/L, 50 mg/L, 60 mg/L, 70 mg/L, 80 mg/L, 90 mg/L, 100 mg/L, 110 mg/L, 120 mg/L, 130 mg/L, 140 mg/L, 150 mg/L, 160 mg/L, 170 mg/L, 180 mg/L, 190 mg/L, 200 mg/L, 210 mg/L, 220 mg/L, 230 mg/L, 240 mg/L, 250 mg/L, 260 mg/L, 270 mg/L, 280 mg/L, 290 mg/L, 300 mg/L, 310 mg/L, 320 mg/L, 330 mg/L, 340 mg/L, 350 mg/L, 360 mg/L, 370 mg/L, 380 mg/L, 390 mg/L, 400 mg/L, 410 mg/L, 420 mg/L, 430 mg/L, 440 mg/L, 450 mg/L, 460 mg/L, 470 mg/L, 480 mg/L, 490 mg/L, 500 mg/L, 510 mg/L, 520 mg/L, 530 mg/L, 540 mg/L, 550 mg/L, 560 mg/L, 570 mg/L, 580 mg/L, 590 mg/L, or 600 mg/L. (4) Soluble Protein

[00216] The nutritional powder, and the nutritional formula provided by the nutrient delivery system, include a hydrolyzed protein. The amount of soluble protein in the nutritional powder can be determined by performing an HPLC analysis of centrifugation supernatants. For example, powders can be reconstituted at a standard dilution and centrifuged, before and after dilution with a buffer. The preparations can then be syringe-filtered and then protein content determined using HPLC.

[00217] The analysis may indicate that the nutritional powder includes soluble protein, as a percentage of total protein, in an amount of about 20% to about 80%. For example, the nutritional powder may include soluble protein in an amount of about 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, or 80%.

3. Use of the Nutrient Delivery System

[00218] The nutrient delivery system, as described above, provides the nutritional formula. The present invention is also directed to a method of producing the nutritional formula. The method may include providing the pod and the nutritional powder described above. The nutritional powder may be positioned within the pod such that the nutritional powder is fully enclosed by the bottom wall, side wall, and lid of the pod. Accordingly, the nutritional powder and the lid may define therebetween the headspace of the pod. As described above, the headspace may include less than about 10% O ₂ .

[00219] The method also includes introducing the fluid into the pod to produce the nutritional formula. Introducing may include the lid receiving the injector or similar device as described above, through which the fluid is delivered into the pod. The fluid may include water.

Additionally, the fluid may be introduced into the pod at a suitable temperature, such as a temperature described herein.

[00220] The method may further include expelling the nutritional formula fr om the pod.

Expelling may include passing the nutritional formula through the outlet port of the pod and into a container (e.g., bottle, glass, and so forth) from which the subject consumes the nutritional formula.

[00221] In some embodiments, the contents of the pod (i.e., the nutritional powder) are intended to be processed (i.e., reconstituted into a liquid product suitable for oral consumption by a subject) within seconds after a hermetic seal of the pod is broken to allow liquid to flow therein, the content to flow therefrom, or a combination thereof. In such embodiments, the pod will typically be a single-use, disposable container. In other embodiments, the pod is sealable or re-sealable and is capable of re-use. In certain embodiments where the pod is sealable or re- sealable, the contents of the pod (i.e., the nutritional powder) may be stored for a short time (typically hours or days) by the consumer prior to reconstituting into a liquid product and the pod may or may not be hermetically sealed at any point.

[00222] In some embodiments, any delay between the time the hermetic seal of the pod is disrupted and the initiation time is less than 1 second. In other embodiments, any delay between the time the hermetic seal of the pod is disrupted and the initiation time is less than 2 seconds. In other embodiments, any delay between the time the hermetic seal of the pod is disrupted and the initiation time is less than 3 seconds. In other embodiments, any delay between the time the hermetic seal of the pod is disrupted and the initiation time is less than 4 seconds. In other embodiments, any delay between the time the hermetic seal of the pod is disrupted and the initiation time is less than 5 seconds. In other embodiments, any delay between the time the hermetic seal of the pod is disrupted and the initiation time is within the range of 1 second to 10 seconds. In some embodiments, a delay between the time the hermetic seal of the pod is disrupted and the initiation time is within the range of 1 second to 30 seconds.

[00223] In these embodiments, a subject desirably consumes at least one serving of the infant formula per day, and in some embodiments, may consume two, three, or even more servings per day. Each serving is desirably administered as a single undivided dose, although the serving may also be divided into two or more partial or divided servings to be taken at two or more times during the day. The methods of the present disclosure include continuous day after day administration, as well as periodic or limited administration, although continuous day after day administration is generally desirable. 4. Method of Manufacturing the Nutritional Powder

[00224] The nutritional powders may be prepared by any known or otherwise effective technique suitable for making and formulating nutritional powders, variations of which may depend upon variables such as the selected ingredient combination, packaging and container selection, and so forth. Such techniques and variations are described in the nutritional art or are otherwise well known to those skilled in the nutritional art.

[00225] Methods of manufacturing nutritional powders typically involve the initial formation of an aqueous slurry containing carbohydrates, proteins, lipids, stabilizers or other formulation aids, vitamins, minerals, or combinations thereof. The slurry is emulsified, pasteurized, homogenized, and cooled. Various other solutions, mixtures, or other materials may be added to the resulting emulsion before, during, or after further processing. The resulting mixture is then heated and dried into powder form, which may be accomplished by spray drying or other heat- treating methods of forming solid particulates in a powder matrix. Other essential or optional materials may also be added to the powder by dry blending, agglomerating, or otherwise combining the added material to the forming or just formed solid particulates.

[00226] If dry blending is used as part of the formulation process, the type and amount of dry blended carbohydrates in a nutritional powder may be analyzed. Analysis may be performed using a microscope, by preparing a microscope slide with a sample of the powder and placing the slide under a standard stereoscopic microscope. The different types of particles are visually analyzed in terms of shape, size, color, and transparency, and measurements are recorded. Each different powder particle and test is extracted using infrared vibrational spectroscopy to confirm its identity.

[00227] Alternatively or as a complement to the above-described method, analysis may be done by static image analysis by testing a sample of the powder using an image analysis sensor (e.g., Malvern Morphologi G3). The analyzer provides a quantitative characterization of the different powder shapes and sizes.

[00228] Alternatively or as a complement to the above-listed methods, analysis may be done by via Differential Scanning Calorimetry (DSC). A sample of powder is evaluated using a Differential Scanning Calorimeter (e.g., TA Instruments' Q200). The analyzer provides a heat flow thermogram, which can differentiate 100% spray dried powders from partially or 100% dry blended powders from glass transition peaks. [00229] The quantitative measurements from the static image analysis and DSC can be correlated to the different powder particles identified microscopically to calculate the type and amount of dry blended carbohydrates in the powder.

[00230] In one embodiment, a suitable manufacturing process may include the preparation of at least three separate slurries: a protein-in-fat (PIF) slurry, a carbohydrate- mineral (CHO-MIN) slurry, and a protein-in- water (PIW) slurry. The PIF slurry may be formed by heating and mixing the oil (e.g., canola oil, corn oil, soy oil, coconut oil, high oleic safflower oil) and then adding an emulsifier (e.g., lecithin), fat soluble vitamins, and a portion of the total protein (e.g., intact pea protein concentrate, milk protein concentrate, whey protein concentrate, nonfat milk) with continued heat and agitation. The CHO-MIN slurry may be formed by adding with heated agitation to water: minerals (e.g., potassium citrate, dipotassium phosphate, sodium citrate), trace and ultra trace minerals (TM/UTM premix), thickening or suspending agent. The resulting CHO-MIN slurry may be held for 10 minutes with continued heat and agitation before adding additional minerals (e.g., potassium chloride, magnesium carbonate, potassium iodide), and/or carbohydrates (e.g., HMOs, lactose, fructooligosaccharide, sucrose, corn syrup). The PIW slurry may then be formed by mixing with heat and agitation of the remaining protein, if any.

[00231] The resulting slurries are then blended together with heated agitation and the pH may be adjusted to the desired range, such as, from 6.6 to 7.5 (including 6.6 to 7), after which the nutritional emulsion is subjected to high-temperature short-time ("HTST") processing (i.e., about 165°F (74°C) for about 16 seconds) or an ultra high temperature (UHT) processing step (i.e., about 292°F (144°C) for about 5 seconds). The nutritional emulsion is heat treated, emulsified, homogenized, and cooled during the HTST or UHT process. Water soluble vitamins and ascorbic acid are added (if applicable), the pH is again adjusted (if necessary). The batch is evaporated, heat treated and spray dried. After drying, the powder may be transported to storage hoppers. The base powder may be dry blended with the remaining ingredients to form the nutritional powder. The nutritional powder is then packaged in appropriate containers (i.e., pods, packages containing one or more pods, or kits containing one or more pods) for distribution. Those of skill in the art will understand that standard intermediate manufacturing steps, such as bulk storage, packing in large bags or drums, transport to other locations, etc., may be

incorporated as part of this process. [00232] In some embodiments, the nutritional emulsion is dried to form a nutritional powder using any methods known in the art. By way of example, nutritional powders can be

manufactured by preparing at least two slurries, which are then mixed, heat treated, standardized, heat treated a second time, evaporated to remove water, and spray dried or dry blended to form a reconstitutable nutritional powder.

[00233] One exemplary method of preparing a spray dried nutritional powder suitable for use in the nutritional powder pods disclosed herein comprises forming and homogenizing an aqueous slurry or liquid comprising predigested fat, and optionally protein, carbohydrate, and other sources of fat, and then spray drying the slurry or liquid to produce a spray dried nutritional powder. The method may further comprise the step of spray drying, dry mixing, or otherwise adding additional nutritional ingredients, including any one or more of the ingredients described herein, to the spray dried nutritional powder.

[00234] Generally, when the nutritional powder for use in the nutritional powder pod is a spray dried nutritional powder or a dry blended nutritional powder, it may be prepared by any suitable known techniques. For example, the spray drying may include any spray drying technique that is suitable for use in the production of nutritional powders. Many different spray drying methods and techniques are known for use in the nutrition field, all of which are suitable for use in the manufacture of the spray dried nutritional powders herein. Following drying, the finished powder may be packaged into nutritional powder pods.

[00235] In other embodiments, the preparation of the nutritional powder comprises an extruded powder. Milling can also be included as a step in preparing the nutritional powder.

[00236] In some embodiments, the ingredients of the nutritional powder may be extruded as part of the process of making the nutritional powder. In certain embodiments, the ingredients are incorporated in the extruder hopper in the form of a dry feed or powder premix. The dry nutritional ingredients enter the extruder just after the point of entry of water. In certain embodiments, the water comprises from about 1% to about 80% by weight of the total weight of the water and dry ingredients. The amount of water added to the nutritional composition may be adjusted within the aforementioned ranges based on the desired physical properties of the extrudate. In certain embodiments, the nutritional ingredients may be premixed with water to form a thick emulsion, which is then fed into the extruder hopper in the form of a viscous liquid or sludge. The term "extrudate" refers to all or a portion of a nutritional composition that exits an extruder.

[00237] In some embodiments, the extruder used to produce the nutritional powder or

extrudate operates in a continuous format. Generally, any extruder known for use in food

processing may be utilized. In certain embodiments, extrusion is performed via a screw

extruder. Said screw extruder may be a twin screw extruder or a single screw extruder. The

extruder screws may consist of shear elements, mixing elements, conveying elements, kneading elements, emulsifying elements, disc elements, or a combination of the above in any

interchangeable order. The barrels of the extruder may be steam heated or electrically heated. In certain embodiments, extrusion takes place at a temperature between about 20 to about 99 °C, from about 30 °C to about 150°C, or from about 70 to°C about 100 . In certain

embodiments, the ingredients are processed in the extruder for about 5 seconds to about 240

seconds or for about 30 seconds to about 180 seconds.

[00238] In some embodiments disclosed herein, the extrudate is dried following extrusion so as to remove most or all of the water contained therein. In such embodiments, any conventional

drying methods may be used to remove the desired amount of water from the nutritional powder.

For example, the nutritional powder extrudate may be dried using a vacuum, convective hot air, a tray dryer, infrared, or any combination of the above. In some embodiments, the nutritional

powder extrudate may be further ground or milled to a desired particle size following drying. In some embodiments, additional protein and carbohydrate ingredients may be added to the final nutritional powder in the form of dry ingredients or a dry blend.

[00239] In some embodiments, in order to increase or enhance the particle porosity of the

nutritional powder, a pressurized gas may be introduced into the nutritional emulsion at a

suitable time during the manufacturing process. This pressurized gas may dissolve into the

nutritional emulsion during the blending stages if these stages are similarly conducted under

pressure. During the spray-drying or extrusion stages, though, the pressure may be reduced,

allowing the depressurized gas to bubble out of the particles of nutritional powder that are being formed at this stage. The exiting gas bubbles may leave a greater number of open pores or

expanded open pores in the nutritional powder particles.

[00240] In some embodiments, after the nutritional powder is packaged into the pod, the pod is sealed and then stored under ambient conditions or under refrigeration for up to 36 months or longer, more typically from about 6 months to about 24 months. In some embodiments, a package is provided containing a plurality of nutritional powder pods. In some embodiments, a package containing a plurality of nutritional powder pods is prepared and stored.

[00241] The present invention has multiple aspects, illustrated by the following non-limiting examples.

5. Examples

[00242] The compositions used for the following examples are illustrated in Table 3.

Composition 1 is further described in Table 4a, while Composition 4 is described in Table 4b.

Example 1

Characterization of the Nutritional Powder

[00243] The nutritional powder described above was evaluated with regards to the size, surface area and shape of the particles comprising the powder, the porosity, thermal properties, bulk density, flowability, free fat content, and the wettability of the powder.

[00244] Particle Size and Shape. A study was conducted to evaluate the size of the nutritional powder particles, as well as their shape. Following the production of the nutritional powder, samples of said powder were collected and analyzed using laser diffraction. From this analysis, the particle size of the nutritional powder was provided as a distribution of the average particle size. Results are summarized in Table 5.

[00245] The size and shape of the particles may further be examined via image analysis, for example, confocal microscopy and transmission electron microscopy. The particle shape and morphology are also assessed for aspect ratio via the aforementioned techniques. For example, the Malvern Morphologi G3 can be used to measure the size and shape of particles by the technique of static image analysis. There are three essential stages in the measurement process; sample preparation and dispersion (this step is critical to getting good results); spatial separation of individual particles and agglomerates. The Morphologi G3 has an integrated dry powder disperser which makes preparing dry powder samples easy and reproducible. The applied dispersion energy can be precisely controlled, enabling the measurement process to be optimized for a range of material types. Dispersion is achieved without explosively shocking the particles, avoiding damage to fragile particles while ensuring strongly agglomerated materials are dispersed. Effective dispersion of fibers can also be achieved. The instrument captures images of individual particles by scanning the sample underneath the microscope optics, while keeping the particles in focus. The instrument can illuminate the sample from below or above, while accurately controlling the light levels. Additionally, polarizing optics can be used to study birefringent materials.

[00246] In summary, these studies determined the size and shape of the nutritional powder particles, which in turn, provides information regarding the wettability and flow properties of the nutritional formula described above. These results demonstrate particle size(s) and shape(s) that provide improved wettability and flow properties relative to a nutritional powder that does not have the same particle size and shape as the nutritional powder disclosed herein.

[00247] Particle Surface Area. In addition to the above examination of the size and shape of the nutritional powder particles, the surface area of the nutritional powder particles is investigated. Samples of the nutritional powder are analyzed via image analysis, for example, confocal microscopy and transmission electron microscopy to yield surface are of said particles. Alternatively, the surface area of the nutritional powder particles may be analyzed according to a Brunauer-Emmett-Teller (BET) multilayer gas adsorption method. In accordance with such methods, "adsorption" is the accumulation of atoms or molecules on the surface of a material. This adsorption is usually described through isotherms, as in, the amount of adsorbate on the adsorbent as a function of its pressure at constant temperature. This accumulation process creates a film of the adsorbate (the molecules or atoms being accumulated) on the surface of the adsorbent. Thus, the BET theory aims to explain the physical adsorption of gas molecules on a solid surface, and serves as the basis for an analysis technique or the measurement of the surface area of a material. Exemplary BET methods include, but are not limited, to those similar to or according to ISO-9277 (Determination of the specific surface area of solid by gas adsorption- BET method). The BET method may be performed on a surface area and porosity analyzer using Krypton (Micromeretics TriStar II 3020).

[00248] In summary, these studies determine the surface area of the nutritional powder particles, which provides information regarding the wettability and flowability of the nutritional powder. It is expected that these results demonstrate a particle surface area that provides improved wettability and flowability relative to a nutritional powder that does not have the same particle surface area as the nutritional powder disclosed herein.

[00249] Thermal Properties. Studies were performed to investigate the thermal properties of the nutritional powder. Samples of the nutritional powder were transferred to a differential scanning calorimeter and examined for thermal properties over a temperature range of 0°C to 120°C . The results are provided in Table 6.

[00250] In summary, these studies determined the thermal properties of the nutritional powder, such as the glass transition temperature and melting temperature, which are useful as a comparison for a new product at a standard moisture range.

[00251] Porosity. A study is conducted to examine the porosity of the particles comprised within the nutritional powder. Following the production of the nutritional powder, a sample is analyzed via a non-wetting based method on a porosimeter. Specifically, the method involves the intrusion of a non-wetting liquid (e.g., mercury) at high pressure into the powder. The pore size is based on the external pressure needed to force the liquid into a pore against the opposing force of the liquid's surface tension. The volume of the open pores and interstitial void are then divided by the envelope powder volume. Values for porosity can be provided in units of % (i.e. from 0- 100%). Measurement of skim milk powder provides values of 40-75%. One exemplary spray dried infant formula may produce a value of about 57%.

[00252] In summary, these studies determine the porosity of the nutritional powder, which in turn, provides information regarding the wettability and flow properties of the nutritional powder and formula. It is expected that these results demonstrate a porosity that provides improved wettability and flow properties relative to a nutritional powder that does not have the same porosity as the nutritional powder disclosed herein.

[00253] Wettability. The wettability of the nutritional powder was also examined. Wettability is defined as the period of time required for 1 teaspoon of powder to settle below the surface of water contained in a glass beaker. Wettability is designed to indirectly measure a powder's hydration characteristics. For example, a small amount of powder is dispersed on the surface of a small beaker of water. Particles which absorb water poorly will remain on top of the water for longer periods of time.

[00254] The method is as follows: 100 mL of tap water was added at the appropriate temperature to a glass beaker. The timing device was zeroed. One level teaspoon (~ 2.0 grams) of powder was scooped. Holding the scoop over the center top of the beaker, the scoop was turned over and the powder was dropped into the tap water and the timer was started. When all the powder had sunk below the water surface, the timer was stopped. Time was recorded in seconds.

[00255] The wettability data indicates improved overall flow performance of the nutritional formula. The results are provided in Table 7.

[00256] Flowability. A study is conducted to evaluate the flowability of the nutritional powder. After the nutritional powder is produced, a sample is transferred to a Brookfield powder flow tester. This instrument provides a flow factor and flow index of the nutritional powder sample.

[00257] Alternatively, the flowability index can be calculated by dividing the vibrated bulk density (VBD) by the loose bulk density (LBD), which were determined as described below. These results are summarized in Table 8.

[00258] Bulk Density. A study was conducted to investigate the density of the nutritional powder. Samples of the nutritional powder were measured for their bulk densities by specifically examining both loose bulk density and vibrated bulk density. The study was conducted as follows: a calibrated vibrated bulk density cylinder was obtained. The bottom section was labeled with the cylinder's volume. The tare weight of the bottom section of the cylinder was recorded. The top on the cylinder was placed and filled to near overflowing with the sample to be analyzed. A powder funnel may be used to simplify this task. While holding the cylinder over a waste can, the top section was removed. A spatula or the top section of the cylinder was used to strike off the excess sample so that it was smooth and flush with the top of the bottom section. A dry cloth was used to remove any powder clinging to the outside of the bottom section. The bottom section (Gross weight) was weighed.

[00259] The vibrated bulk density was calculated by following the sample preparation described in the loose bulk density. Then the cylinder was placed on the vibrated bulk density apparatus making sure it rested against the stop pins. The cylinder was clamped into place. The timer was set and preset for repeatable one minute cycles. This ensured a similar vibration cycle for all samples. After making sure that the vibrator apparatus was set at an amplitude of 5, the vibration cycle was started. When completed, the cylinder was unclamped and removed. While holding it over a waste can, the top section was removed. A spatula or the top section of the cylinder was used to strike off the excess sample so that it was smooth and flush with the top of the bottom section. A dry cloth was used to remove any powder clinging to the outside of the bottom section. The bottom section was weighed.

[00260] In summary, both loose and vibrated bulk densities provided information on the nutritional powder, and may be important in the reconstitution of said powder. These results demonstrate powder bulk densities that provide improved wettability and reconstitution characteristics relative to a nutritional powder that does not have the same bulk density as the nutritional powder disclosed herein. The results are provided in Table 9.

[00261] Free Fat Content. A study was performed to analyze the free fat content of the nutritional powder. The determination of fat free content was performed by stirring 2.00 g of nutritional powder in 80 mL of hexane (or another non-polar solvent such as petroleum ether) for 10 minutes, filtering the suspension through Whatman No. 41 paper into a tared beaker, evaporating the solvent at 80 °C, and measuring the non-volatile residue gravimetrically.

[00262] These results demonstrate a fat free content that provides improved flowability relative to a nutritional powder that does not have the same fat free content as the nutritional powder disclosed herein. The results are provided in Table 10.

[00263] Reconstitution. Generally, a nutritional powder reconstitution test was used to evaluate how thoroughly the nutritional powder was reconstituted under the operating conditions of a nutrient delivery system, and to determine a corresponding reconstitution rate.

[00264] Generally, according to this test, same size portions (e.g., portions of 2-5 g samples) were taken from the same batch of the nutritional powder to be tested. These portions were weighed both before and after drying (various type of drying can be utilized as long as each portion was dried using the same drying method, e.g., conventional drying techniques such as convection or IR can be utilized) to determine the initial moisture content of each portion (i.e., the weight lost to drying). The average initial moisture content (by weight) was determined by averaging the results from the multiple portions.

[00265] The weight of a resealable nutritional powder pod was measured both with and without a test sample of the nutritional powder enclosed therein to determine the initial weight of the sample of nutritional powder within the pod. Example amounts of the test samples of the nutritional powder were in the range from 2-150 grams.

[00266] The test system was configured to accommodate and operate under the operating conditions of a nutrient delivery system, as follows. The pressure within the pod, as well as the temperature of the water that contacts the nutritional powder and the amount of water flowing through the pod were controlled and measurable. For this test, the pod containing the test sample of the nutritional powder was inserted into the test system, and the system was set to deliver a certain amount of water (e.g., about 25-500 mL) at a certain temperature (e.g., in the range of 5- 50° C) under a certain pressure (e.g., 0.5-15 bar, or approximately 7-217 psia) into and through the pod. Under this test, the ratio of powder weight (grams) to water weight (grams) (where the density of water was taken to be 1 g/mL) was lower than 1 : 1 (e.g., 1 :1.1, 1 : 1.2, 1 : 1.3, 1 :2, 1 :3, 1 :5, etc.). In other words, relatively less powder (in grams) was used as compared to the amount (in grams) of water. A sufficiently large collection bottle was placed under the dispenser of the test system to receive the homogeneous liquid product output. The test system was started, and the homogeneous liquid product was collected in the collection bottle. It was intended that the test system may be a working nutrient delivery system operating under the above-specified conditions or a model system configured to simulate a nutrient delivery system and operating under the above-specified conditions.

[00267] Rate of Reconstitution: The rate of reconstitution is determined using the general test method and system described above, except that once the test system is started, aliquots are taken from the collection bottle or sample cups every 5 seconds until the product is fully dispensed. The total weight of reconstituted solids for each aliquot is determined in the same manner described above. The rate of reconstitution is determined by plotting, for each aliquot of liquid product collected, the weight of total reconstituted solids versus the collection time, thereby resulting in a "gram/ml●second" value.

[00268] In another embodiment, the reconstitution rate is determined by first turning on the microwave to warm up for 45 5 minutes. Funnel and tubing are set-up on the pod exit port of the nutrient delivery system, and 12 sample cups were labeled 1-12 accordingly. The nutrient delivery system is started at a water flow rate of 15 mL/second, and collection of the nutritional formula samples commenced as soon as formula entered the cup and is collected for 5 seconds. After 5 seconds, the tubing extending from the exit port is moved to the next cup (e.g., sample cup 2). This is continued until all of the nutritional formula had been dispensed fr om the nutrient delivery system.

[00269] Following completion of the nutrient delivery system run, an empty sample cup is tared, and each sample is weighed and recorded. Sample pads are placed in a microwave balance, and are tared (e.g., wait until the screen shows 0). A sample cup is taken and stirred for 5 seconds with a clean, unused syringe. Next, the syringe is filled with the sample and dispensed back into the cup. The syringe is filled again, and filled to a volume of 2 mL, except for samples 1-4, which are filled with 1 mL of sample. Next, the sample pads are removed from the microwave, and on the fuzzy side of one of the pads, sample is dispensed slowly from the syringe in a circular motion onto the center of the pad and moving outward. The other pad is placed on top of the aforementioned pad (fuzzy side down), and the two pads are pressed together. The pads are placed back into the microwave onto the balance, the microwave door closed, and the start button pressed to begin the process, which beeps and starts printing upon completion of the test. The percentage of total solids is recorded, and this is done for each sample. [00270] All of the sample weights (g) are added up together to get the total weight. The sample weight is multiplied by the total solids (%) to get the sample total solids (g). Next, the sample solid total is multiplied by 1000 to convert the sample total solids to milligrams. Finally, the sample solids total (mg) is divided by the total weight (g) by the sample time (sec) to get the total solids (mg) per total weight (g) per sample time (sec). The results are provided in Table 1 1.

[00271] Reconstituted Yield: The total solids in the final liquid product is measured using any standard drying technique (e.g., via a forced air oven or microwave drying technique) to remove the water from the final liquid product.

[00272] Next, the theoretical total solids content is determined according to the calculation below using an assumption that 100% of nutritional powder from the pod is delivered in the final liquid product.

[00273] Theoretical total solids = (total initial weight in grams of the powder sample in the model pod - average initial moisture in grams) / (water delivered in grams + total initial weight in grams of the powder sample in the model pod).

[00274] Finally, the reconstituted yield, which is the amount of reconstituted powder in the final liquid product is determined by dividing the final liquid product total solids by the theoretical solids (i.e., reconstituted yield = final liquid product total solids / theoretical total solids). The reconstituted yield is reported as a number (e.g., 0.XX or as a percentage, e.g., XX%).

[00275] In another embodiment, reconstitution yield was determined by running the nutrient delivery system with a water flow rate of 120 mL over 5 seconds and allowing the pod to remain within the system. One large sample cup was labeled with the run number, and a collection beaker or funnel was placed under the exit valve with the tubing set-up. Next, the accumulator was filled with approximately 120 mL of water and the nutrient delivery system was run again, with the original pod remaining within. The rinse water sample was collected within the sample cup. Similar to above in the reconstitution rate analysis, an empty sample cup was tared on a balance, and the rinse water sample weighed. In addition and like recited above, the steps used to determine total solids via microwave/pad analysis were used for the rinse water sample;

however, 5 ml of sample was used relative to the smaller volumes listed above.

[00276] Then the percentage of total solids of the rinse water was multiplied by the grams of rinse water to get the grams of total solids of the rinse water. Next, the grams of total solids of the rinse water were divided by the percentage of total solids of the powder to get the grams of powder remaining in the pod. The grams of powder remaining in the pod were divided by the grams of powder put into the pod to get the ratio of powder remaining in the pod relative to powder put in the pod. Finally, the ratio of powder remaining in the pod relative to powder put in the pod was subtracted from 1 and multiplied by 100 to get the percentage of powder reconstituted. The results are provided in Table 12.

[00277] Spectral Properties. A study is conducted to evaluate the spectral properties of the nutritional powder. The spectral characterization is assessed by transferring a sample of the nutritional powder to a spectrophotometer and measuring the Hunter L, a and b values. These values are dependent on the wettability, emulsion stability, and emulsion homogeneity of the nutritional formula, and indicate the lightness and color-opponent dimension of the nutritional formula.

[00278] Determination of Soluble Protein. A study was performed to analyze the soluble protein content of the nutritional powder as a percent of total protein. The soluble protein content was analyzed by reconstituting the powders at a standard dilution, and then centrifuging before and after dilution in a buffer such as 0.05M KH ₂ P0 ₄ , pH 2.9, or such as 0.05M NaH ₂ P0 ₄ , 0.15M NaCl, pH 7.5. The preparations were then syringe-filtered through a 0.45 μm membrane prior to protein determination by reversed phase HPLC or by size exclusion HPLC. The soluble protein concentrations were reported as a percentage of total protein. The results of these studies are shown in Table 13.

Example 2

Characterization of the Nutritional Formula

[00279] The nutritional formula described above was evaluated with regards to foaming, gas entrapment/entrainment or density, viscosity, spectral properties, dispersibility and emulsion stability.

[00280] Dispersibility. A study was conducted to investigate the dispersibility of the nutritional formula. Following the production of the nutritional formula by a mechanical shaker, a sample was removed from and immediately poured through an 80 mesh screen. The receiving flask was filled approximately ¼ full with tap water to dislodge any particles that may remain in the flask, and poured through the screen. The screen was not rinsed with tap water. The particles remaining on the screen were rated using scaled photographs. If one lump that is 0.5 inch or greater remains on the screen, repeat the test. Each sample was tested in duplicate, and the average reported as the final result. Because the precision of the method is limited by the capability of the subjective rating, duplicate measurement was required. Results are presented in Table 14.

[00281] In an additional experiment, the dispersibility of the nutritional formula was measured by the "80 Mesh Determination of Infant Formulas," which describes the firmness and solubility of particles from the gel, sediment, and creaming within a product. This evaluation attempts to identify what product defects may lead to a clogged nipple.

[00282] This experiment employed either a 3" U.S. Standard 80 mesh sieve, a 5" U.S. Standard 80 mesh sieve, or a 8" U.S. Standard 80 mesh sieve. The 5"or 8" sieve was used for samples in containers 11 oz. or greater. The 3" sieve was used for samples in containers 8 oz. or smaller.

[00283] A flow of tap water was adjusted to a temperature of 110°F. The sieve was held over the sink and the sample (nutritional formula) was poured through the sieve. The sample container was then filled with water to rinse and poured through the sieve again. The water flow was fanned with an empty hand and the sieve rinsed for 20 seconds for samples that were a concentrated liquid, and rinsed for 3 seconds for sample that were ready-to-feed samples. The remaining particles on the screen were given a value of 1-6 using the following scale: 1 - No particles; 2 - First evidence of very small particles to a slight amount of small particles with a maximum size of approximately 1.0 mm; 3 - Slight amount of small particles with a few moderate size particles; 4 - Moderate amount of medium sized particles with a moderate amount of small particles; 5 - A heavy amount of varying sized particles covering most of the sieve screen; 6 - An excessive amount of any sized particles which cover the entire sieve screen and may plug the screen openings.

[00284] In another embodiment, the dispersibility of the nutritional formula was measured using a mesh sieve. For example, the nutritional formula was provided by the nutrient delivery system and poured through an 8 inch, 80 mesh sieve. Next, 100 mL of slightly warm water was added to the sample container and gently swirled. The residual rinse was also passed through the 80 mesh sieve, ensuring that the pour was distributed thoroughly over the area of the sieve. The total number of particles present on the sieve were measured using a mm stick and /or ruler. The size of the particles was stratified into groups consisting of less than 1 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm and greater than 5mm.

[00285] In another embodiment, dispersibility of the nutritional formula may be assessed after the nutritional powder is reconstituted via hand shaking. First, a tape was placed along a bench and/or table, which was used to mark the distance of the shake. The amount of powder was weighed to provide approximately an 8 oz serving, and the water bath was set to approximately 105 °F to 110 °F. An amount of 210 mL of heated water was placed into an Avent baby bottle, and the preweighed powder was placed into the baby bottle. The baby bottle was capped, and the Metronome application was set to 242. Next, the baby bottle was held horizontally beside one end of the tape, a stop watch was started, and the baby bottle vigorously moved back and forth horizontally along the distance of the tape for 10 seconds. This distance and time roughly corresponds to a 40 count by Metronome beat. After this period of bottle shaking, the bottle cap was immediately removed and the contents poured through an 80 mesh sieve. The baby bottle was rinsed slightly, in order to remove any foam or clumps, and the rinse fluid poured through an 80 mesh sieve. Similar to above, the number and size of particles covering the surface of the sieve were measured and recorded. The size of the particles was stratified into groups consisting of less than 1 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm and greater than 5 mm.

[00286] The dispersibility indicates an improved flow formula relative to a nutritional formula lacking one or more of the components in the amounts described above. The results are provided in Table 15.

[00287] Foaming. A study was conducted to evaluate the foaming of the nutritional formula described above. As the nutrient delivery system provides the nutritional formula at a water flow rate of 5 mL/second, the nutritional formula was captured within a graduated cylinder. The total volume of foam and liquid (mL) in the cylinder was measured at 0 minutes, 15 minutes and 30 minutes after being dispensed from the nutrient delivery system. Foaming is indicated by a number of different parameters, such as: total foam volume measured at the aforementioned listed intervals, and foaming ratio of the initial volume divided by the volume at the variable time points listed above. The foam ratio describes the foam dissipation over a variable time interval for a sample.

[00288] In another embodiment, the foaming procedure was performed by providing the nutritional formula from the nutrient delivery system, and immediately pouring the nutritional formula slowly down the side of a slightly tilted 250 mL graduated cylinder. Near the end of the pour, the container used to capture the nutritional formula was swirled and any remaining foam was transferred into the 250 mL graduated cylinder. The cylinder was set upright to determine where the layer of foam begins and ends. A flashlight may be used if necessary. The divisions on the cylinder that encompass the foam layer were counted and recorded, which was referred to as the initial time point. The foam layer was observed again at 15 minutes and 30 minutes, and the amount of foam at each time point was recorded in the manner as described above. It should be noted that as the foam dissipates there may be pockets of foam and/or bubbles clinging to the side of the cylinder. Only foam that was dense and was part of the bulk layer was counted towards the foam volume.

[00289] In another embodiment, foaming procedure was performed by providing the nutritional formula by reconstituting the nutritional powder via hand shaking. First, a tape was placed along a bench and/or table, which was used to mark the distance of the shake. The amount of powder was weighed to provide an 8 oz serving, and the water bath was set to approximately 105 °F to 110 °F. An amount of 210 mL of heated water was placed into an Avent baby bottle, and the preweighed powder was placed into the baby bottle. The baby bottle was capped, and the Metronome application was set to 242. Next, the baby bottle was held horizontally beside one end of the tape, a stop watch was started, and the baby bottle vigorously moved back and forth horizontally along the distance of the tape for 10 seconds. This distance and time roughly corresponds to a 40 count by Metronome beat. After this period of bottle shaking, the bottle cap was immediately removed and the contents were immediately poured slowly down the side of a slightly tilted 250 mL graduated cylinder. Near the end of the pour, the container used to capture the nutritional formula was swirled and any remaining foam was transferred into the 250 mL graduated cylinder. The cylinder was set upright to determine where the layer of foam begins and ends. A flashlight may be used if necessary. The divisions on the cylinder that encompass the foam layer were counted and recorded, which was referred to as the initial time point. The foam layer was observed again at 15 minutes and 30 minutes, and the amount of foam at each time point was recorded in the manner as described above. It should be noted that as the foam dissipates there may be pockets of foam and/or bubbles clinging to the side of the cylinder. Only foam that was dense and was part of the bulk layer was counted towards the foam volume.

[00290] The nutritional formula displays reduced foaming relative to a nutritional formula lacking one or more of the components in the amounts described above. This reduced foaming, in turn, provides a decrease in negative side effects associated with foaming, e.g., gassiness, thereby providing an improved overall quality in the experience of consuming the nutritional formula described herein. The results are provided in Tables 16 and 17.

[00291] Gas Entrapment/Density. A study was conducted to evaluate and compare the density of the nutritional formula. Specifically, once the nutritional formula was prepared using a mechanical shaker, and the density was assessed using an automated density meter (Mettler Toledo DE51). The results are presented in Tables 16 and 17.

[00292] In some embodiments, in order to determine if entrapped air is responsible for any difference in formula density (relative to a nutritional formula lacking one or more of the components in the amounts described above), a subset of samples may be transferred to a Buchner flask, with a stir bar, and sealed with a rubber stopper. The samples are placed under vacuum (~25 in. Hg) for approximately 2 hours to remove air from product. Density

measurements, as described above, are then repeated for degassed samples. Alternatively, samples may be degassed via centrifugation.

[00293] In another embodiment, entrapped/entrained air was measured using a PAPEC

Squeezer. A compression piston full was removed to the end of a sample tube, and rotated one revolution. The sample, which was prepared using the nutrient delivery system using a water flow rate of 5 mL/second, was poured into the tube and the tube filled up to the beginning of the threaded area at the top of the tube, which was approximately 240 mL. The screw on the cap was replaced, and the bleed valve was confirmed to be open (e.g., arrows are pointing up and down). Next, the tube was slightly tilted with the brass bleed valve at the top, and the compression piston turned clockwise to dispel the air pocket. When bubbles appeared out of the bleed valve, the bleed valve was stopped and closed (e.g., arrows are horizontal). The compression piston was rotated clockwise, while counting the turns (e.g., 1 turn = 360°) and fraction of turns, until the fluid rises to the back score mark on the pressure indicating tube. The number of turns was recorded, including the fraction of turns. Finally, the percentage of entrained air was calculated using the following formula:

[00294] Entrapped/Entrained Air = (total turns including fraction of turns) - 0.5 * 2.2 (1)

[00295] The entrained air measurements provide information regarding the flow characteristics of the nutritional formula as well as information regarding any side effects that may be associated with consumption of the nutritional formula. The nutritional formula has an air entrainment that promotes positive side effects and negates negative side effects arising from the consumption of nutritional formulas that lack one or more of the components in the amounts described above.

[00296] Viscosity. A study is conducted to investigate the viscosity of the nutritional formula. The nutritional formula is provided by a mechanical shaker. The viscosity is assessed by transferring a sample of the nutritional formula to a rheometer and measuring the viscosity of said formula.

[00297] In summary, the viscosity provides information regarding the overall flow

performance of the nutritional formula. The measured viscosity indicates an improved flow performance of the nutritional formula relative to a nutritional formula lacking one or more of the components in the amounts described above.

[00298] Spectral Properties. A study is conducted to evaluate the spectral properties of the nutritional formula. Once the nutritional formula is provided by a mechanical shaker, the spectral properties are assessed by transferring a sample of the nutritional formula to a spectrophotometer and measuring the Hunter L, a and b values. These values are dependent on the wettability, emulsion stability, and emulsion homogeneity of the nutritional formula, and indicate the lightness and color-opponent dimension of the nutritional formula.

[00299] The Hunter L, a, and b values of the nutritional formula are improved relative to a nutritional formula lacking one or more of the components in the amounts described above.

[00300] Emulsion stability. A study is conducted to evaluate the stability of the emulsions within the nutritional formula. The nutritional formula is provided by a mechanical shaker, hand shaking, or a nutrient delivery system.

[00301] Specifically, the nutritional formula is analyzed for emulsion size using laser diffraction, wherein a refractive index of 1.462 is used for the dispersed phase and 1.332 is used for the continuous phase (water). Emulsion particle size within the nutritional formula is provided as a distribution of the average particle size. Particle size of the emulsion is measured at variable time points post production of the nutritional formula.

[00302] It is expected that the nutritional formula exhibits an improved emulsion stability relative to a nutritional formula lacking one or more of the components in the amounts described above. [00303] Digestible Protein. A study was conducted to evaluate the digestibility of the proteins, by determining protein digestion indicators after a gastrointestinal digestion procedure. The digestion indicators were evaluated by first adjusting the pH of a nutritional formula (e.g., about 40 mL) to pH 4.5 using an acid (e.g., HC1). To this solution was added USP pepsin (e.g., 1.00 mL of a 56 mg/mL solution), and the mixture was stirred at room temperature for about one hour. Then a solution of USP pancreatin amylase/protease and USP pancreatin lipase (e.g., 4.00 mL of 6.94 mg/mL solutions in water) was added, and the mixture was stirred at room

temperature for about two hours. The digests were then centrifuged (e.g., at about 31,000 x g, at about 20 °C, for about 4 hours). The supernatant was then analyzed by HPLC to determine its molecular weight profile. The pellet was tested for insoluble protein using acid hydrolysis and amino acid profile analysis. The digestible protein, as a percentage of total protein, was determined, in which the digested protein was the protein in the supernatant (i.e., not in the centrifugation pellet). Specifically, digestible protein (% of total proteins) = [(total protein - insoluble protein)/total protein] x 100%. Additionally, the total protein was 10.6g per 100g of nutritional powder. The results of these studies are shown in Tables 18 and 19.

[00304] Iron Solubility. A study is conducted to evaluate the soluble iron in the nutritional formula. Specifically, a colorimetric determination of iron in the supernatant obtained after simulated gastric (i.e., pepsin) and intestinal (i.e., pancreatin) digestions is performed.

[00305] For the simulated digestions, the pH of a nutritional formula (e.g., about 40 mL) is adjusted to pH 4.5 using an acid (e.g., HC1) or the nutritional formula may be diluted in USP simulated gastric fluid. To this suspension is added USP pepsin (e.g., 1.00 mL of a 56 mg/mL solution), and the mixture is stirred at room temperature for about one hour. Then the pH is adjusted to 7.5 with 0.5M NaHCO ₃ , a solution of USP pancreatin amylase/protease and USP pancreatin lipase (e.g., 4.00 mL of 6.94 mg/mL solutions in water) is added, and the mixture is stirred at room temperature for about two hours. The digests are then centrifuged (e.g., at about 31,000 x g, at about 20 °C, for about 4 hours).

[00306] The supernatant iron is then determined by colorimetric assay using a complexing agent sold under the name FERROZINE. A 2 ml aliquot of the supernatant is pipetted into a 1- dram vial and to this is added 1.00 ml freshly prepared Test Buffer (i.e., 0.60 M Na acetate, pH4.5, containing hydroxylamine hydrochloride at 8.0% (w/v). A 2.00 ml aliquot of a reagent blank supernatant is diluted in the same manner in order to quantify the soluble iron contribution from reagents.

[00307] Additionally, a series of iron standard solutions are prepared in Milli-Q Plus water from a ferrous sulfate heptahydrate reference material. A 1.00 ml aliquot of each iron standard solution is pipetted into a respective 1-dram vial, and to each vial, 1.00 ml test buffer is added.

[00308] Into each 1-dram vial, that is the sample digest, digest reagent blank, Milli-Q Plus water blank, and iron standard solutions, 50 μl of freshly prepared colorimetric solution (at 0.85%, w/v) of the complexing agent sold under the name FERROZINE (i.e., 8.5 mg of 3-(2- pyridyl)-5,6-diphenyl-l,2,4-triazine-4', 4"-disulfonic acid, monosodium salt, dissolved in 1.00 ml of Test Buffer) is added. Thirty minutes after addition of the colorimetric solution, the visible light absorbance at 562 nm, vs. Milli-Q Plus water, is measured with a spectrophotometer. A calibration curve of absorbance v. iron concentration is plotted and the iron concentration in the sample digest is calculated (after subtraction of the reagent blank absorbance contribution) by linear regression from the calibration curve. The iron concentration determined for the sample digest is the soluble iron concentration. [00309] It is expected that the nutritional formula exhibits an improved iron solubility relative to a nutritional formula lacking one or more of the components in the amounts described above.

[00310] Zinc Solubility. A study is conducted to evaluate the soluble zinc in the nutritional formula. Specifically, determination of zinc in the supernatant obtained after simulated gastric (i.e., pepsin) and intestinal (i.e., pancreatin) digestions is performed.

[00311] For the simulated digestions, the pH of a nutritional formula (e.g., about 40 mL) is adjusted to pH 4.5 using an acid (e.g., HC1) or the nutritional formula may be diluted in USP simulated gastric fluid. To this suspension is added USP pepsin (e.g., 1.00 mL of a 56 mg/mL solution), and the mixture is stirred at room temperature for about one hour. Then the pH is adjusted to 7.5 with 0.5M NaHC0 ₃ , a solution of USP pancreatin amylase/protease and USP pancreatin lipase (e.g., 4.00 mL of 6.94 mg/mL solutions in water) is added, and the mixture is stirred at room temperature for about two hours. The digests are then centrifuged (e.g., at about 31,000 x g, at about 20 °C, for about 4 hours).

[00312] The supernatant zinc is then determined by Atomic Absorption (AA) Spectroscopy or by Inductively Coupled Plasma (ICP) Spectroscopy. An aliquot of a reagent blank supernatant is also prepared in order to quantify the soluble zinc concentration from reagents. Additionally, a series of zinc standard solutions are prepared.

[00313] A calibration curve is plotted using the measurements from the zinc standard solutions and the zinc concentration in the sample digest is calculated by linear regression from the calibration curve. The zinc concentration determined for the sample digest is the soluble zinc concentration.

[00314] It is expected that the nutritional formula exhibits an improved zinc solubility relative to a nutritional formula lacking one or more of the components in the amounts described above.
