TECHNICAL FIELD

Embodiments generally relate to a coated particle, methods of preparing a coated particle, and methods of using a coated particle. More particularly, embodiments relate to a coated particle for a comestible product to provide a relatively reduced carbohydrate content.

BACKGROUND

There has been a recent focus to reduce carbohydrate content, such as sugar content, in comestible products to deliver relatively healthier products to consumers. Some conventional strategies include substituting sugars with ingredients such as polyols and high-intensity sweeteners. Compositions to reduce sugar content in fat-based food products might, however, increase an amount of fat to provide suitable flow characteristics at the expense of desirable dietary fat content. Moreover, few technologies modify the physical structure of sugar at a basic level so that it delivers more sweetness per gram of the sugar. Those that do, such as DouxMatok (Petah-Tikva, Israel), involve the coating of inert silica nanoparticles having a high surface area with sucrose molecules to form a product via hydrogen bonding. Flavor compounds in food ingredients might, however, result in complex and unpredictable flavor profiles such that solutions to address defects with additives might not be applicable to many food particles.

Carbohydrate content in some compositions to reduce sugar content might also be high relative to other components. For example, a sugar component in a mixture might be over 67% by weight of the mixture. In addition, and despite a high relative amount of carbohydrate content, flavor (e.g., short lasting sweetness, too sweet, etc.) and/or texture profiles (e.g., sticky, chalky, etc.) of a composition might nonetheless be unsuitable owing to flavor characteristics (e.g., bihemess, sweetness, etc.) or other properties (e.g., fat content, etc.) of ingredients. Moreover, methods used to make some compositions that reduce carbohydrate content might experience a failure owing to the physical characteristics of ingredients. There is, therefore, considerable room for improvement to provide a coated particle for a comestible product. BRIEF SUMMARY

Embodiments include a coated composition that includes a coated particle. The coated particle may include a food particle coated by a carbohydrate, wherein the coated particle has an average particle size from about 10 pm to about 250 pm, and wherein the coated particle has a surface area fraction of the carbohydrate that is greater than an average weight fraction of the carbohydrate. The average particle size of the food particles may be, for example, less than about 25 pm. The coated particle may have a substantially non-spherical and irregular shape.

Some exemplary embodiments may include food particles including a mixture of cocoa and a protein. The protein may be, for example, whey protein, soy protein, rice protein, and/or fava bean protein. The protein may be a protein concentrate or a protein isolate. In one example, the protein is at least 90% pure whey protein isolate. In a further example, the protein is milk protein from a non-fat dried milk. In exemplary embodiments, a cocoa nonfat to protein weight ratio is about 3 or greater. For example, a cocoa nonfat to whey protein weight ratio may be about 18.4, a cocoa nonfat to soy protein weight ratio may be about 8.7, a cocoa nonfat to rice protein weight ratio may be about 9.3, and a cocoa nonfat to fava bean protein weight ratio may be about 9.3.

Some exemplary embodiments may include sugar as the carbohydrate. In one example, the coated particles are carbohydrate-coated rice starch particles (e.g., sugar-coated rice starch particles) in a white chocolate composition. In another example, the carbohydrate includes sucrose, which may be at least 25% by weight of the carbohydrate. In a further example, the carbohydrate is sugar mixed with 20 dextrose equivalent (DE) com syrup solids (CSS), maltodextrin, Fibersol-2, maltodextrin, soluble fiber, hydrocolloids, cellulose derivatives, starch hydrolysates, and/or pregelatinized starch. The weight ratio of the food particles to the carbohydrate may be from about 1 : 1 to about 4: 1. The surface area fraction of the carbohydrate may be from about 30% to about 80%.

Embodiments include a method of forming a coated composition. In exemplary embodiments, the method includes combining a food particle and a carbohydrate to form a spray-drying mixture. In one example, the food particle and the carbohydrate may be combined in water to form a slurry mixture. In exemplary embodiments, the method includes selecting the food particle to have a predetermined average particle size and refining the food particle when the food particle does not have the predetermined average particle size. In one example, the food particle is selected to have an average particle size of less than about 25 pm. In another example, at least one of two or more types of food particles may be independently refined to have an average particle size of, e.g., less than about 25 pm when the food particle includes two or more types of food particles. In a further example, a slurry mixture may be refined to provide a refined mixture with particles having an average particle size of, e.g., less than about 25 pm. In exemplary embodiments, the method includes spray drying the mixture to form a coated composition including a plurality of coated particles.

Some exemplary embodiments may include preparing a comestible product using a coated particle. Some exemplary embodiments may include preparing a beverage product using a mixture of a bitter component (e.g., cocoa) and a protein. In exemplary embodiments, a bitter drink may be prepared by, e.g., first leaching out color and flavor (e.g., using water) from a vegetable and then combining extract solids with a water-dispersible protein. A mixture of exudate and protein may optionally be spray-dried with a carbohydrate to form a reduced calorie sweeter drink that advantageously also has relatively reduced bitterness. Among advantages of certain exemplary embodiments are, therefore, a masking of the bitterness of a food particle, a sugar-coated particle substantially free of non-food ingredients, a sugar-coated particle substantially free of non-sugar sweeteners, an improved texture or mouth feel of the food particle, and/or an increased sweetness per gram of sugar in a sugar-coated particle.

DESCRIPTION OF EMBODIMENTS

Referring to FIG. 1, a method 10 to form a coated composition 12 including carbohydrate-coated particles 14 is shown according to an embodiment. A machine may implement one or more aspects of the method 10 automatically. For example, an aspect of the method 10 may be implemented by a set of logic instructions stored in a machine- or computer- readable storage medium such as random access memory (RAM), read only memory (ROM), programmable ROM (PROM), firmware, flash memory, 3DXP memory, etc., in configurable logic such as, for example, programmable logic arrays (PLAs), field programmable gate arrays (FPGAs), complex programmable logic devices (CPLDs), or any combination thereof. For example, computer program code to carry out operations shown in the method 16 may be written in any combination of one or more programming languages, including an object oriented programming language such as JAVA, SMALLTALK, C++ or the like and conventional procedural programming languages, such as the“C” programming language or similar programming languages. Additionally, logic instructions might include assembler instructions, instruction set architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, state-setting data, configuration data for integrated circuitry, state information that personalizes electronic circuitry and/or other structural components that are native to hardware (e.g., host processor, central processing unit/CPU, microcontroller, etc.).

The method 10 includes combining a carbohydrate 16 and food particles 18 to form the carbohydrate-coated particles 14. Any coating process may be used to coat food particles with a carbohydrate. For instance, a coated particle may be produced using a Wurster coater (Freund-Vector Corporation, Marian, IA, USA) or similar processing equipment, which coats particles by suspending the particles in air while causing a coating material to build-up on the exterior of the particle. Particle coating can also be achieved using a Granurex (Freund-Vector Corporation) or similar processing equipment, which coats a particle that is fluidized by movement in a circular track. One coating process includes a spray drying process. In exemplary embodiments, sugar is combined with food particles in water to form a solution or a suspension that is spray-dried to form sugar-coated particles. Notably, coating food particles with sugar increases the surface area of the sugar per gram relative to pure sugar of a similar particle size to deliver more sweetness per gram of sugar. In some embodiments, sugar masks the bitterness or off-taste of food particles, such as in the case of cocoa powder or certain protein food particles. In the illustrated example, the method 10 also optionally includes using the coated composition 12 as a comestible product 20 or as an ingredient that is combined with one or more other ingredients to form the comestible product 20. In one example, the comestible product 20 is a confectionery product (e.g., chocolate, paste, filling, etc.).

In exemplary embodiments, carbohydrate-coated particles are free or substantially free of non-food ingredients. In addition, carbohydrate-coated particles can incorporate flavors and flavor modifiers (e.g., bitter blockers, high potency sweeteners, etc.). Carbohydrate-coated particles may also be free or substantially free of water or may have a water activity of up to 0.6, above which microbial contamination concerns may limit the carbohydrate-coated particles from being a ready-to-eat ingredient. In exemplary embodiments, carbohydrate- coated particles have moisture content less than about 10%, alternatively less than about 5%, by weight of the total weight of a coated composition (e.g., per weight of spray-dried particles). Carbohydrate-coated particles may also have an average particle size selected for a specific application or use.

The average particle size of carbohydrate-coated particles may be selected by, for example, adjusting a nozzle of a two-fluid pneumatic atomizing nozzle in a spray-drying apparatus when a spray drying coating process is used to form spray-dried carbohydrate-coated particles. Atomizing devices for spray drying include, for example, rotary discs, pneumatic nozzles, hydraulic nozzles, sonic nozzles, and variations thereof. In exemplary embodiments, an average particle size of carbohydrate-coated particles may be from about 10 micrometers (pm) to about 250 pm, alternatively from about 10 pm to about 200 pm, alternatively from about 10 pm to about 180 pm, alternatively from about 10 pm to about 150 pm, alternatively from about 10 pm to about 125 pm, alternatively from about 10 pm to about 100 pm, alternatively from about 10 pm to about 50 pm, alternatively from about 20 pm to about 40 pm, alternatively about 40 pm, alternatively about 30 pm, alternatively about 20 pm, alternatively about 10 pm. Carbohydrate-coated particles may also have a substantially non- spherical and irregular shape. For example, the shape of carbohydrate-coated particles may be less than 50% spherical and/or more than 50% irregular, alternatively more than 80% irregular.

Food particles may include, but are not limited to, cocoa powder, carob powder, dietary fiber, protein, milk protein isolate, whey protein isolate, casein protein isolate, vegetable protein, vegetable protein isolate, vegetable protein concentrate, vegetable powder, vegetable extracts, protein concentrates, protein isolates, vegetable fiber, insoluble dietary fiber, soluble dietary fiber, a starch, a modified starch, a starch derivative, a hydrocolloid, etc. Food particles may be water-soluble or insoluble in water. Soluble non-sugar ingredients, such as, for example, starches, derivatives of starches, related carbohydrates, related polysaccharides, other food polymers and hydrolysates, such as, for example, proteins, that are amenable to spray drying and are dispersible in water may serve as suitable food particles for carbohydrate-coated particles formed by spray drying. Food particles may be free or substantially free of sugar and/or free or substantially free of any sweetener. For example, food particles might have sugar content less than about 10%, alternatively less than about 5%, alternatively less than about 1%, by weight of the total weight of the food particles.

In exemplary embodiments, food particles may be very small with a high surface area and act as a carrier for sugar. In exemplary embodiments, an average particle size of food particles is about 50 pm or less, alternatively about 40 pm or less, alternatively about 30 pm or less, alternatively about 20 pm or less, alternatively about 10 pm or less, alternatively about 5 pm or less. The food particles may be, for example, rice starch. In exemplary embodiments, carbohydrate-coated rice starch particles may be suitable for relatively sweet comestible products such as white chocolate. Additionally, the food particles may include a mixture of cocoa and a protein. In exemplary embodiments, the protein is whey protein, soy protein, rice protein, fava bean protein, and/or milk protein. The protein may be isolates or concentrates of proteins. In one example, a cocoa nonfat to protein weight ratio is about 3 or greater. In exemplary embodiments, a cocoa nonfat to whey protein weight ratio is about 18.4, a cocoa nonfat to soy protein weight ratio is about 8.7, a cocoa nonfat to rice protein weight ratio is about 9.3, and a cocoa nonfat to fava bean protein weight ratio is about 9.3. In one beverage example, a bitter drink may be prepared by first leaching out color and flavor (e.g., using water) from a vegetable and then making a combination of extract solids with a water-dispersible protein. A weight ratio of extract solids to protein may be, for example, at least 3. In exemplary embodiments, the vegetable is cocoa. In exemplary embodiments, the protein is derived from whey, soy, rice, and fava bean. In exemplary embodiments, the protein may be isolates or concentrates of proteins.

Material used to coat food particles may be a carbohydrate (e.g., C _x (H20) _y , where x may be a number different than y). In exemplary embodiments, a carbohydrate has a glass transition temperature (T _g ) greater than 60 degrees Celsius (°C) dry. For example, a sugar may have a T _g above room temperature. Examples of carbohydrates include but are not limited to sucrose, lactose, maltose, trehalose, com syrup solids of 40 Dextrose Equivalents (DE) or less, maltodextrins, resistant maltodextrins, Fibersol-2, soluble fibers, hydrocolloids, cellulose derivatives, pregelatinized starch, etc. Thus, in one example, a process for making coated particles includes spray drying a suspension containing an insoluble particle and a film-forming carbohydrate. In exemplary embodiments, carbohydrate-coated particles include food particles and sugar. A sugar may be any monosaccharide or disaccharide. In some embodiments, a sugar is sucrose, maltose, or trehalose. In some embodiments, a sugar is a monosaccharide stabilized by maltodextrin. In some embodiments, a sugar is a sugar polyol, which may be used alone when, for example, its T _g exceeds room temperature. A sugar polyol may include, for example, isomalt, lactitol, lactitol hydrates, maltitol, high maltitol syrup, inulin hydrolysates, etc. In addition, sugar polyols having a T _g less than room temperature may be used when in the presence of, for example, maltodextrin, hydrogenated starch hydrolysates, and so on. Sugars therefore include, for example, sucrose, maltose, trehalose, lactitol, isomalt, a disaccharide, an alcohol of a disaccharide, a dextrose-maltodextrin mixture, a fructose- maltodextrin mixture, a sorbitol-maltodextrin mixture, a xylitol-maltodextrin mixture, an erythritol-maltodextrin mixture, a monosaccharide-maltodextrin mixture, an alcohol of a monosaccharide-maltodextrin mixture, and so on. The physical structure of sugar may be modified by embedding food particles inside a sugar matrix to form sugar-coated particles.

Notably, a carbohydrate covers exterior surfaces of coated particles in an unexpected amount given an average weight fraction of the carbohydrate in the coated particles. For example, a surface area fraction of carbohydrate (e.g., weight fraction of carbohydrate at the particle surface, percentage of particle surface covered by carbohydrate) is greater than an average weight fraction of the carbohydrate in the coated particles. In embodiments of sugar- coated particles that are 50/50 by weight sugar (e.g., in a particle of a weight ratio of 1 : 1 - nonsugar: sugar), sugar is present on food particle exterior surfaces in a proportion of about 66% or greater of the food particle exterior surfaces area despite being 50% by weight of the sugar-coated particles. In another example where sugar-coated particles are 75/25 by weight sugar (e.g., 3: 1 nonsugar: sugar weight ratio), sugar is present on food particle exterior surfaces in a proportion of about 33% or greater of the food particle exterior surface area despite being 25% by weight of the sugar-coated particles. Sugar-coated particles surprisingly deliver more sweetness per gram of sugar-coated particle than a mixture of sugar and nonsugar of the same weight ratio and are advantageous for inclusion into comestible products. Also notably, a weight ratio of food particles to carbohydrate may be about even and more preferably favors the food particles. For example, food particle(s) and carbohydrate(s) may be combined at a weight ratio of about 1 : 1 to about 4: 1, alternatively about 1: 1 to about 3: 1, alternatively about 1: 1, alternatively about 2: 1, alternatively about 3: 1. However, an average weight fraction of a carbohydrate in coated particles may be 67% or less such as, for example, in a 1:2 weight ratio of food particle(s) and carbohydrate(s).

Accordingly, an advantageous effect of sugar-coated particles is to increase a perception of sweetness by changing a sweetness profile when, for example, a coating material is sucrose and a food particle is bland, soluble in water, and without flavor (e.g., a whey protein isolate, WPI). Additionally, there may be a rapid initial rise in sweetness of a sweetness profile that then lingers to result in the perception of greater sweetness when a sugar-coated food particle is compared to the same weight ratio of a simple mixture of nonsugar and sugar. Meanwhile, an advantage of a spray drying process to form coated particles is that it is possible to mill insoluble particles in the presence of water to an average particle size desirable for coated particles. By contrast, traditional methods would require reducing these particles in the presence of fat using a roll refiner or in the presence of very high air pressure using a jet mill. An example of such a mill is the Boston Shearmill (Admix, Inc., Londonderry, New Hampshire, USA), which is capable of reducing insoluble soft particles down to less than 5 pm.

In one example, a reduced sugar confectionery product with reduced calories may be formed from carbohydrate-coated particles. Also, use of carbohydrate-coated particles might not increase fat content of a confectionery product relative to a conventional confectionery product. Conventionally any attempt to replace sugar results in a fat-based confectionery product that contains more fat to allow it to flow, which is required for manufacturing and for the perception of a smooth and a pleasing mouth feel of the confectionery product. By coating a particle, the particle becomes smooth and results in a fat-based confectionery product that does not require more fat than one with crystalline sugar. An advantage of sugar in a fat-based confectionery product is its density of 1.54 grams per milliliter (g/mL). When incorporated in a fat-based confectionery product at 50% of the total weight of the confectionery product, for example, it takes up less volume than other non-fat ingredients resulting in a fluidity that requires less fat than other non-fat ingredients. By coating a particle, the coated particle has a relatively smooth surface that allows it to flow past its neighbor and has a relatively lower density resulting in no extra fat for suitable flow or mouth feel. Carbohydrate-coated particles may, therefore, be incorporated into any low-moisture food systems. In exemplary embodiments, low-moisture food systems are fat-based. Examples of applications for carbohydrate-coated particles include, but are not limited to, chocolates, fat-based cremes, confectionery nut butter pastes, and so on. Aspects of embodiments are further described in the context of the following examples that are presented by way of illustration, not of limitation. Moreover, it should be understood that a machine may implement one or more aspects of the following method(s), and that one or more steps of the following example method(s) may be combined, omitted, bypassed, re arranged, and/or flow in any order. Moreover, any or all steps of the following example method(s) may be manually implemented (e.g., with human intervention, etc.).

Example 1: Spray-dried WPI particle formation.

A control solution was formed by first weighing WPI. The WPI was Hilmar™ 9000 whey protein isolate (Hilmar Cheese Company, Hilmar, CA). Deionized water was weighed and the WPI was added to the water a tablespoon at a time with mixing by a Silverson L4RT high shear mixer (Silverson Machines, Inc., East Longmeadow, MA) until the powder was fully incorporated into the water to minimize foaming, thereby forming a 7.5% by weight control solution of WPI. The WPI dissolved in the water in the sense that the WPI dispersed in the water without forming a sediment. The control solution was refrigerated for about 45 minutes (min) prior to spray drying to minimize the potential for bacterial growth.

The control solution was then spray-dried with a Buchi mini spray dryer B-290 (Buchi Corporation, New Castle, DE). The inlet temperature was set to 160 °C (320 degrees Fahrenheit (°F)), which provided an outlet temperature of at least 95 °C (203 °F) before solution was pumped into spray dryer and 70 ° C-90° C (158 ° F-194 ° F) while the solution was drying in the spray dryer. The control solution was placed in an ice bath and the supply tube was inserted into the control solution. A fine white powder of the spray-dried food particles was formed in the collection jar of the spray dryer. FIG. 2 shows scanning electron microscope (SEM) images 22 including an SEM image 22a of spray-dried WPI food particles.

Example 2: Sugar-coated WPI particle formation.

Food particles of WPI were coated with sucrose using a lab spray dryer unit. A spray drying solution was formed by first separately weighing and then mixing together the sucrose and WPI. The sucrose was baker’s special sugar (ASR Group, West Palm Beach, FL, USA) having an average crystal size of about 250 pm, although sucrose having other crystal sizes may alternatively be used, as the sugar is dissolved. Confectioner’s sugar is preferably avoided, as the sucrose is diluted by starch. The WPI was Hilmar™ 9000 whey protein isolate. Deionized water was weighed, and the powder mixture was added to the water a tablespoon at a time with mixing by a Silverson L4RT high shear mixer (Silverson Machines, Inc., East Longmeadow, MA) until the powder mixture was fully incorporated to minimize foaming, thereby forming a 1 : 1 by weight spray-drying solution of 7.5 wt% sucrose and 7.5 wt% WPI. The spray-drying solution was refrigerated for about 45 minutes prior to spray drying to minimize the potential for bacterial growth.

The spray drying solution was then spray-dried with a Buchi mini spray dryer B-290 (Buchi Corporation, New Castle, DE). The inlet temperature was set to 160 °C (320 °F), which provided an outlet temperature of at least 95 °C (203 °F). The spray-drying solution was placed in an ice bath and the supply tube was inserted into the spray-drying solution. A fine white powder of the sugar-coated particles was formed in the collection jar of the spray dryer when the outlet temperature of the spray dryer was 70° C-90 ° C (158 ° F-194 ° F). FIG. 2 shows an SEM image 22b of spray-dried sugar-coated WPI food particles.

Example 3: Sugar-coated WPI particle characterization.

The spray-dried sugar-coated WPI particles were characterized to determine their particle size distribution, their surface content of sugar, and their relative taste characteristics.

FIG. 3 shows a graph 24 of particle size distribution of a sample of the spray-dried sugar-coated WPI particles. A Horiba LA-960 (Kyoto, Japan) particle size analyzer outfitted with diode light source was used to determine the particle size distribution by laser diffraction. The Horiba was first charged with a medium-chain length triglyceride (Neobee ^® M-5, Stepan Company, Northfield, IL). The oil was circulated through the cell and the response was set to blank. The spray-dried material was slowly added until the target concentration-response of 70%-80% transmittance was reached. The particle size distribution was then measured while circulating the suspension through the measurement cell. The mean sugar-coated WPI particle size was measured to be 10.53 pm.

Dynamic vapor sorption (DVS) is a gravimetric technique that measures the rate and amount of moisture absorption by a sample. A DVS Advantage (Surface Measurement Systems, Allentown, PA) instrument was used to estimate the surface composition of the sugar- coated WPI particles by measuring the moisture absorption properties of the surface of a particle. The DVS instrument is constructed with a sample holder on one side of a fulcrum and a counterbalance on the other side. The counterbalance weight was selected so that after the sample was added to the sample holder, the net mass between the sample holder and counterweight was less than 50 milligrams (mg). Table 1 shows the results from these measurements. Table 1: DVS Measurement Results

Approximately 60 mg of test material was placed on a previously tared sample holder. The balance was programmed to dry the sample in 200 mL per minute (mL/m) air flow controlled at 0.1% relative humidity (RH) at 25 °C (77 °F) for 6 hours (h). After the drying, during a linear perturbation, the humidity was linearly increased to 15% relative humidity (RH) over a two-hour period of time and then decreased linearly back to 0.1% RH over the subsequent two-hour period of time. The net weight was calculated by subtracting the weight of the sample at the end of the drying from the maximum weight of the sample during the linear perturbation. The specific uptake was calculated by dividing the net weight divided by the sample weight at the end of drying.

The amorphous sugar (sucrose) was created using a table-top cotton candy machine (Cotton Candy Maker, Waring Pro, East Windsor, NJ). Approximately 10 mL of baker's special sugar was added to the center of the hollow spinning disk. The cotton candy machine was turned on, causing the spinning disk to start spinning and to be heated underneath. In about five minutes, the machine formed cotton candy by forming small strands coming out of the spinning disk which immediately cooled and collected in the bowl around the spinning disk as amorphous sugar. Approximately 60 mg of cotton candy was immediately collected and placed in the DVS sample holder, which was placed into the DVS for analysis by the gravimetric technique.

The specific uptake for crystalline sugar was observed to be zero. The specific uptake for WPI was 0.0390 and for amorphous sugar was 0.0031, indicating that the method differentiated between WPI, amorphous sucrose and crystalline sucrose. The specific uptake for the spray-dried sucrose-WPI blends would then have only a portion of the exterior composed of each chemical entity. The ratio of each chemical entity on the surface was estimated as a linear combination of the specific uptake response of each chemical entity. The linear estimate then was the estimate for the proportion of each chemical entity on the spray- dried particle surface.

Table 1 shows that the effective amount of sugar at the surface of a spray-dried sugar- coated WPI particle was greater than the average amount of sugar in the spray-dried sugar- coated WPI particle. Despite being only 50% by weight sucrose, a 1 : 1 spray-dried sugar-coated WPI particle was determined to have a surface that was about 2/3 sucrose. Despite being only 25% by weight sucrose, a 1 :3 spray-dried WPI sugar-coated particle was determined to have a surface that was about 1/3 sucrose. Since the perceived sweetness of a particle is presumably a function of the amount of sugar at the surface of the particle, these spray-dried sugar-coated WPI particles would be expected to taste sweeter than a physical mixture of WPI powder and 10X powdered sugar at the same weight ratio of WPI to sucrose.

Sensory taste tests were conducted to evaluate the sweetness intensity and the level of long-lasting sweetness of the spray-dried sugar-coated WPI particles in comparison to a corresponding 1: 1 by weight blend of 10X powdered sugar and spray-dried WPI. Four out of five human taste testers identified the spray-dried sugar-coated WPI particles as being sweeter and having a longer-lasting sweetness than a 1: 1 by weight blend of 10X powdered sugar and spray-dried WPI. The 1 : 1 by weight blend of 10X powdered sugar and spray-dried WPI had a delayed sweetness that tapered off more quickly than the spray-dried sugar-coated WPI particles, which had a sweetness that was detected immediately by the human taste testers. The human testers did not report a clumping of the powder in the mouth.

Example 4: Measurement by surface composition.

ADVS instrument (Surface Measurement Systems, Allentown, PA, USA) was operated at 25 °C. A 50 pm- 100 pm sample was spread onto an aluminum foil pan 1.0 centimeter (cm) in diameter (made from heavy duty aluminum foil of 1.5 cm diameter) and supported on a 0.4 g wire holder. The sample was first dried at 0. l%RH for 18 h (w;), followed by humidification at 15% RH for 6 h (w _e ). Surface adsorption was calculated as follows:

(w; - w _e )/ w _e ~ MCdb(l5%RH)

(1)

where MCdb(l5%RH) is the dry basis moisture content at 15% relative humidity. Table 2 shows the results from these measurements. Table 2: Surface Adsorption Results

Example 5: SEM of particles and interior characterizations.

A powder is encased in an adhesive of epoxy with hardener (5.0 g Epoxy with 0.6 g hardener). The adhesive is used to coat the bottom of a BEEM® (Better Equipment For Electron Microscopy, Inc., Pennsylvania, USA) embedding capsule. Powder is added to the capsule and the capsule backfilled with adhesive and allowed to cure for 24 h. The capsule is cut by a razor blade and then thin layer cut using a microtome (Leica RM 2245, Wetzlar, Germany). The cut layer with particles are identified by a change in color to that of the brown powder. The samples are attached to a stub with adhesive tape and placed into the SEM chamber. The SEM chamber is set nominally to 80 Pascals and the sample imaged at varying magnifications. If powder is not observed in imaged slice, additional slices are generated and imaged.

FIG. 4 shows a group of SEM images 26 including an SEM image 26a of spray-dried cocoa powder 35, an SEM image 26b of spray-dried cocoa powder 35/sucrose/Fibersol-2, and an SEM image 26c of spray-dried Fibersol-2. FIG. 5 shows a group of SEM images 28 including an SEM image 28a of spray-dried cocoa powder 35 and an SEM image 28b of spray-dried cocoa powder 35/lactose (2: 1). FIG. 6 shows a group of SEM images 30 including an SEM image 30a of nonspray-dried rice starch and an SEM image 30b of spray-dried rice starch- sucrose (dry weight ratio of 2: 1 of rice starch to sucrose). Notably, cocoa has a darker image in SEM than sucrose or Fibersol-2 and sucrose. The spray-dried cocoa/sucrose/fibersol-2 is not spherical but actually has a rather uneven surface and the interior is filled with cocoa. This uneven surface is also observed with spray-dried cocoa and lactose. Meanwhile, spray-dried Fibersol-2 is quite spherical and hollow. The nonspray-dried rice starch shows particles that have cross-section distances of around 5 pm and they are loosely spread over the image. By contrast, the spray-dried mixture of rice starch and sucrose displays clumps that range from 5 pm to 25 pm in cross-sectional distance.

Example 6: Glass transition of the powder.

About 10 mg-l5 mg of powder is added to a T-zero pan, compacted to the bottom and sealed with a T-zero hermetic lid (TA Instruments, New Castle, Delaware, USA). The sample is then scanned at 5 °C/min from 25 °C to 100 °C. The glass transition is observed as a step change in heat flow at the inflexion point using Trios software (TA Instruments).

Example 7: Particle size distribution.

A Horiba particle size analyzer (LA-960, Edison, NJ, USA) was operated using Neobee 895 oil (Stepan Specialty Products LLC, Northfield, Illinois, USA) as the continuous phase. The Neobee oil was used once and discarded. The instrument was operated without sonication adding the amount needed to obtain a 80%-90% obscuration. The circular and agitator speeds were each set at speed one to prevent agglomeration of particles during measurement. The data was analyzed according to particle volume and the 50-percentile by volume reported.

Example 8: Observing particles under optical microscope.

A sample of powder was spread onto microscopic slide and a drop of oil was added to the powder. The two were mixed together and then a portion was smeared on a clean portion of the slide. A cover slip was placed over the sample. The sample was examined under 100 and 200 power of magnification using bright light using a binocular light transmission microscope (BX53, Olympus Corporation of the Americas Headquarters, Center Valley, Pennsylvania, USA). The image was collected using an Olympus DP26 digital camera and the image recorded using CellSens (Olympus Corporation).

cleaner, cap size, tip size, cap gap, and cleaning needle size. By turning the nozzle cap ½- revolution, it brought the opening of the annular air flush with the opening for the liquid. This facilitated a narrower plume of spray, which increased particle size and resulted in more spherical particles.

Table 4: Spray Drying Conditions

Table 5 shows the operating conditions of inlet temperature, outlet temperature, and vacuum pressure.

Table 5: Operating Conditions

Coated particles were characterized. Table 6 shows the glass transition, particle size, surface adsorption, and surface area coverage fraction for coated particles from a carbohydrate.

Table 6: Characterization of Sugar-Coated Particles

Optical microscopy images in mineral oil and lecithin showed a dark interior and a smooth exterior. Cross-sectional SEM images showed a darker interior with a lighter exterior. When suspended in 30% cocoa butter, the 2: 1 cocoa powder/lactose composition was flowable, but the 3: 1 cocoa powder/lactose composition was relatively pasty indicating that additional fat might be needed in order for it to be processed into a chocolate bar (when a bar is desired). The oral texture of the spray-dried particles dispersed in solidified cocoa butter sought to address whether the cocoa powder which was evident on the surface of the spray-dried particle was also impacting on the particle as it dispersed in the mouth.

When the cocoa was not evident on the surface, the particles were observed to clump leading to a lumpy mouth feel. By contrast, an 82% cacao chocolate made with crystalline sugar does not clump and has a smooth melt down. At 2: 1 and 3: 1 formulations in Table 6, there was progressively less clumping. This was surprising considering that WPI-sucrose was not reported to clump in the mouth in Examples 2 and 3 when 67%-70% of the surface was sucrose, midway between the lactose coverage of 2: 1 and 3: 1 formulation in Table 6 of 83% and 39%, respectively. Clumping, therefore, may be addressed at least in part by having carbohydrate (e.g., sugar) cover from about 30% to about 80% of the surface of a particle (e.g., on about 30% to about 80% of an exterior-facing surface of a food particle). Clumping may also be addressed by having an identity (e.g., structural property, functional property, etc.) of the reminder of a coated particle be more similar to that in a particle such as WPI. Notably, the flavor of the spray-dried powders containing cocoa were quite bitter.

Example 10: Biterness from spray-dried cocoa.

Two suspensions of lactose and cocoa powder were prepared in water. Table 7 shows the measurements of various formulations tested and manufacturing conditions tested.

Table 7: Measurements of Lactose and Cocoa Suspensions and Manufacturing Tested

The spray dryer set-points and operating conditions were the same as in Example 9. Powders were then tasted directly. Spray-dried powders were ranked in bitterness from greatest to least as follows: 10.1, 10.2, 10.3 and 10.4. Both high shear mixing and time of spray drying contributed to the bitterness of the spray-dried powder.

Example 11 : Spray drying compared with roller refining.

Spray drying set-up was the same as in Example 9. Table 8 shows the operating conditions of inlet temperature, outlet temperature, and vacuum pressure.

Table 8: Operating Conditions

Table 9 shows the formulation of the feed suspension including cocoa powder (with sub-composition), sugar, maltodextrin, and water.

Table 9: Formulation of Feed Suspension

Table 10 shows a characterization of a spray-dried finished powder compared to a roll refined mass.

Table 10: Comparison of Spray Dried Coated Particles and Roll Refined Mass

The same composition was roll refined to 20 pm. Refined crumb was dispersed into mineral oil and dropped into jaw of a Fowler Micrometer (Japan) and tightened to maximum torque. Table 11 shows the formulation of the roll refined composition.

Table 11: Formulation of Roll Refined Composition

Chocolates were prepared from the roll refined composition (Table 11) and the spray- dried composition (Table 9). Table 12 shows a comparison of the formulations and flow properties of the spray-dried composition and the roll refined composition.

Table 12: Comparison of Spray Dried Composition and Roll Refined Composition

Example 12: Sprav drying rice protein with sugar.

Table 13 shows the formulation of the feed suspension including rice protein, sugar, and water.

Table 13: Formulation of Feed Suspension Including Rice Protein

Table 14 shows the spray drying conditions of inlet air temperature, feed liquid pump, atomizing air flow (Q-flow), nozzle cleaner, cap size, tip size, cap gap, and cleaning needle size.

Table 14: Spray Drying Conditions

The particle size distribution of the rice protein received was 325 mesh and consisted of 84% protein, 0.8% fat and less than 5% moisture. The Q-flow and nozzle cleaner cycles were chosen to keep the suspension from clogging the spray dryer atomizing nozzle. Fine particles with an average particle size of 20 pm were produced.

Example 13: Preparation of 1000 ppm stock solution of Stevia.

Stevia stock solution was prepared as follows. 100 mg of Purefruit Plus natural sweetener system (monk fruit extract & Stevia extract), obtained from Tate & Lyle (London, United Kingdom), was dissolved in lOOg deionized water to prepare 1000 ppm stock solution.

Example 14: Preparation of 1000 ppm stock solution of ClearTaste.

ClearTaste stock solution was prepared as follows. 200 mg ClearTaste powder (MycoTechnology Inc., Aurora, Colorado, USA) was added to 200 g deionized water to prepare 1000 ppm stock solution.

Example 15: Spray drying cocoa, lactose, and flavor modifiers.

Table 15 shows the formulation of the feed suspension including cocoa, lactose, and flavor modifiers Stevia and ClearTaste. The slurry batch included water preheated to 73°C. Table 15: Formulation of Feed Suspension Including Flavor Modifiers

The spray dryer set-points were as follows: inlet temperature l60°C; aspirator 100%; pump 30%; nozzle Cleaner 2-second interval. Table 16 shows measurements for the spray- dried formulations with flavor modifiers.

Table 16: Measurements For Formulations Including Flavor Modifiers

These formulations were tasted in chocolates and in powders. Tasters reported overwhelming bitterness and did not observe sweetness or cacao in the samples. The samples were also chalky.

Example 16: Spray drying debittered cocoa.

Debittered cocoa had an average particle size of 70 pm. A 30% solids slurry was prepared (40 g debittered cocoa powder, 20 g lactose, 140 g water). After the spray dryer was set up (same as in Example 9), the beaker is placed on a hot plate (70 °C) and the feed tube was inserted into the slurry. However, the slurry could not flow through the feed tube. 40 g of water was added to the slurry to decrease the solid content to 25%. Flow appeared to improve at the very beginning, but it did not last long and the slurry ultimately failed to flow through the nozzle system. The pressure built up and the feed tube connected to the inlet popped off several times. More water was added to dilute the slurry to 10%, but flow remained unimproved. The nozzle tip was changed to 2.0 mm (maximum available size) and the tube was cleaned but flow remained unimproved. Notably, expected atomization was not observed. Thus, the nozzle was clogged and prevented atomization of the slurry. The debittered cocoa did not change in particle size when dispersed in water. Even if the debittered cocoa could have been spray dried, the particles would have been too gritty for an acceptable chocolate without further particle size reduction.

Example 17: Creating a coated particle from a coarse insoluble pea protein.

The Silverson L4R bench laboratory mixer with the vertically slotted head (intended for disintegration of vegetable matter) (part no. 7250-HS0001) was used to break up particles below 20 pm as measured in Example 11. This was accomplished by mixing the slurry for 3 min. The slurry was composed of 2: 1 pea protein/lactose of 35% solids in water. The slurry, once ground to less than 20 pm, was then spray dried through the spray drier configured as described in Example 9. Surprisingly, this process solved the problem of a clogged spray dryer nozzle encountered in Example 16.

Other wet mills, such as Boston Shearmill (Admix, Inc., Londonderry, New Hampshire, USA) can be used to break up vegetable matter to less than 20 pm. This is surprisingly effective given the difficulty of breaking up vegetable matter when it is dry.

Example 18 Spray drying refined debittered cocoa.

A 35% solids slurry was prepared (solids being 2: 1 : 1 of debittered cocoa/sucrose/Fibersol 2). The slurry was processed in the Silverson Mixer to break up the debittered cocoa as in Example 17. Spray drying conditions in Example 9 were used. A chocolate was made with this spray-dried powder designated SDP-18. It was composed of 16% liquor (54% fat), 18.7% cocoa butter, 0.3% lecithin and the 65.0% SDP-18. Tasters reported that it was sweet, fruity, but not cacao or bitter flavor. A lack of cacao flavor was surprising given that liquor usually delivers a strong flavor. The lack of bitterness was as expected from the debittered cocoa. Example 19: Sprav drying cocoa 35 and WPI.

A 35% solids slurry was prepared (195:35:42:25:3 of water/cocoa 35/sucrose/Fibersol- 2/WPI). WPI was a typical whey protein isolate (90% protein). The slurry was spray dried according to the conditions in Example 9, producing SDP-19 with about 3.7% fat, 29.7% cocoa nonfat and 2.6% whey protein. A chocolate made was composed of 28.9% liquor (54% fat), 8.8% cocoa butter, 5.4% milkfat, 0.3% lecithin, 0.015% vanillin and 56.6% SPD-19, resulting in a chocolate with 32.1% fat. Tasters judged the chocolate as sweet, bitter, cacao, and mouth drying. This was unexpected since the bitterness of spray-dried cocoa 35 was overwhelming in Example 15, so much that it prevented the perception of any other flavor like sweet or cacao. Thus, a relatively small amount of WPI results in a sample with a desirable cacao-bitter-sweet flavor profile. The sample is not chalky, which was surprising given that SDP-l5’s (made with lactose as the sugar) were observed to be chalky. The cocoa nonfat to whey protein ratio in the SDP-l 9 was about 11.4 and in the chocolate was about 18.4 (including the cocoa nonfat in the liquor).

Example 20: Oat fiber and pea fiber

A 35% solids slurry was made using oat fiber (solids 2: 1: 1 oat fiber/sucrose/Fibersol- 2). At this solid level and after mixing using the Silverson mixer, the slurry was too viscous to pump. After dilution to 22% solids, the slurry remained too viscous to pump. This mixture could not be spray dried. The same was tried with pea fiber (Roquette Pea Fiber I50M, Roquette America Inc., Geneva, IL, USA)) and was also found too viscous to pump. Microscope images showed the pea fiber to have a length to cross-sectional ratio of around 20. This was unexpected, as spray drying with sugar was tested to address viscous nature of fiber.

Example 21 : Rice starch.

A sample of RTE rice starch (Remy B7, Beneo Gmbh, Mannheim, Germany) was made into a 40% solids slurry (solids 5:3:2 rice starch/Fibersol-2/sucrose). Rice starch was shown to have a cross section of 4 pm-7 pm and appeared roughly spherical (FIG. 30a). The slurry was spray dried (per Example 9). SDP-21 particles included multiple starch granules and had an average size of 16 pm (FIG. 30b). Surprisingly, if the slurry were 15% slurry and of the same solids ratio, a resulting composition designated SDP-2lb had a larger average particle size of 20 pm. A white chocolate was made with SDP-21 including 30.0% cocoa butter, 0.24% lecithin, 0.01% PGPR, 0.03% vanillin, 17.75% NFDM, 52% SDP-21. The viscosity was 3000 cP at 20 rpm with a yield stress of 5.2 dyn/cm ² . Tasters indicated it was sweet and pleasant and surprisingly lacked the raw starch flavor as would normally be expected for a white chocolate containing 25% starch. Example 22: 2000 ppm Stevia in cocoa 35 and lactose.

A 35% solids slurry was created (solids 2: 1 cocoa 35/lactose) with 2000 ppm Stevia and 80 ppm bitter blocker (same source as in Example 15). The slurry was spray-dried according to the conditions in Example 9. The SDP-22 was tasted as a powder and there was no indication of sweetness from Stevia. Rather, the bitterness of the cocoa completely overwhelmed perception. This was unexpected since 2000 ppm Stevia is about 5-10 times more concentrated than in Example 15 and these results indicated that Stevia could not improve the flavor. The ratio of cocoa 35 to lactose was not considered to impact the perception of bitterness, so that in regards to bitterness a ratio of 2: 1 was considered equivalent to 1: 1.

Example 23: Non-fat dried milk cocoa 35. sucrose com syrup solids and Stevia.

A 35% solids slurry was created (solids 50:9.1:20.9:20 cocoa 35/NFDM/sucrose/20 DE CSS) creating SDP-23. SDP-23 contained 44.5% cocoa nonfat and 3.5% milk protein with a ratio of cocoa nonfat to milk protein of 12.7. This was made up into a sweet chocolate including 61.8% SDP-23, 4.4% NFDM, 16% liquor, 2% AMF, 15.5% cocoa butter, 0.3% lecithin. This chocolate had 34.8% cocoa nonfat and 3.8% milk protein resulting in a ratio of cocoa nonfat to milk protein of 9.2. Tasters considered the SDP-23-sweet chocolate to be cocoa, sweet, slight bitter, pleasant and mouth drying. A reference chocolate was made without spray drying but of the same components in the same proportion. Surprisingly, the reference chocolate was considered sweeter, with more cacao flavor. The chocolate made with SDP-23 was noted to clump up in the mouth, which likely interfered with the perception of flavors. When 100 ppm Stevia was added to SDP-23 chocolate the tasters considered that it tasted as sweet as the reference chocolate. Surprisingly, milk protein was capable of reducing the bitterness of cocoa to a point where other flavors, such cocoa and sweet, could be perceived. The cocoa nonfat to protein ratio for SDP-19 chocolate was 18.4 compared to 9.2 for SDP-23 chocolate. This was unexpected because milk protein is predominantly casein (around 83%) and casein micelles are larger with less surface area than globular whey protein.

Example 24: Spray dry high protein nut milk with cocoa sucrose and M040 maltodextrin

A slurry was made wherein the water was wholly provided by Silk® (Danone North America, White Plains, NY, USA) high protein nut milk. The nut milk had 10 g of protein, 8 g of fat, and 3 g of carbohydrate in 240-mL. Using a Silverson L4RT high shear mixer, 30 g of cocoa 35, 20 g of crystalline sucrose, and 10 g of M040 Maltodextrin (Grain Processing Corporation, Muscatine, IA, USA) was added to 140 mL of nut milk. After spray drying according to Example 9, the resulting spray-dried particle, SDP-24, contained 37.0% cocoa nonfat and 8.1% protein, resulting in a cocoa nonfat to protein ratio of 4.6. According to the ingredient listing, the nut milk contained filtered almond water, filtered cashew water, pea protein, high oleic canola oil and the remainder of the ingredients were less than 2%. Most of the protein was likely provided by added pea protein. Tasters considered that SDP-24 tasted of cacao, sweet, and slightly bitter, and was considered a pleasant chocolate flavor, if not a bit different from typical milk chocolates. When this particle was first made via spray drying, it was not realized at the time that this composition resulted in a reduction of the bitterness of the cocoa. In revisiting this sample after observations in Example 15, it was surprising how pleasant the flavor was in contrast to that of Example 15.

Example 25: Slurries of cocoa 35 with different vegan and dairy milks.

In order to screen proteins with cocoa, different milk and vegan milks were purchased and combined with cocoa. This was chosen so that all of the water in the mixture was provided by the milk and it was based on a milk formula of 8 g of protein in 240 mL. The general formula was 20 g cocoa and 80 g milks. Table 17 shows the taste response for various slurry formulations including milks.

Table 17: Taste Response for Slurry Formulation Including Milks

From the tasting results, protein appeared to interact with cocoa bitter flavorants and prevented their perception. Soy protein reacted with the cacao to effectively reduce bitterness, but milk protein was not nearly as effective. Since WPI was quite effective, casein does not appear to be nearly as effective in addressing bitterness from cocoa in the slurry prior to spray drying. This observation was surprising considering that NFDM in SDP-23 was observed to decrease bitterness of cocoa and provide a pleasant flavor. Surprisingly, Silk high protein nut milk was less effective at reducing bitterness in a slurry than in SDP-24.

Example 26: Slurries of pea rice lentil and fava-bean proteins with cocoa.

Slurries of four different proteins were evaluated for their impact on the perception of cocoa 35 flavor in water. Table 18 shows the taste response for various slurry formulations including proteins. In table 18, (*) indicates wet grinding using Silverson L4RT mixer for 3 m at 8000 rpm with a slotted mixing head and (†) indicates wet grinding using Silverson L4RT mixer for 3 m at 8000 rpm with an emulsion mixing head.

Table 18: Taste Response for Slurry Formulation Including Proteins

Rice protein isolate and fava bean protein concentrate were effective in reducing bitterness and astringency of cocoa while allowing the perception of cacao. Surprisingly, pea protein was not effective in the slurry in reducing cocoa bitterness, but according to Example 24, pea protein in SDP-24 was effective in reducing bitterness of cocoa. An application may include a process wherein a finely divided cocoa is leached of flavors and colors in a fashion similar to tea, and the resultant exudate is very bitter. This bitterness can be reduced substantially by adding proteins to the resultant exudate such as soy protein, rice protein, fava bean protein, or WPI resulting in a palatable and/or refreshing drink.

Example 27 Example Food Particle.

One function of a coated particle is to replace sugar in fat-based systems while minimally increasing the fat content. Clumping in the mouth might be observed when a surface contains more than 66%-7l% sugar. When sugar was 66%-7l% of the surface (with WPI), however, the coated particle delivered a flavor of sweeter than a similar composition chocolate made solely by roll refining. In another example, a 2: 1 cocoa to lactose formulation had 83% of the cocoa surface covered by lactose while with a 3: 1 cocoa to lactose formulation had 39% of the cocoa surface covered by lactose wherein clumping was progressively less but not eliminated. This indicates that a coated particle more like WPI and less like cocoa may prevent clumping during mastication in the mouth.

Meanwhile, a coated particle containing cocoa 35 as the core might have overwhelming bitterness. When choice of protein and its ratio with cocoa nonfat is sufficient (cocoa nonfat to protein ratio of at least 3), then the bitterness and astringency of cocoa was reduced to acceptable levels allowing the perception of sweet and cacao flavors. For instance, bitterness and astringency was reduced when the ratio of cocoa nonfat to WPI in chocolate was 18.4, when the ratio of cocoa nonfat to soy protein was 8.7, when the ratio of cocoa nonfat to rice protein was 9.3, when the ratio of cocoa nonfat to fava bean protein was 9.3, when the ratio of cocoa nonfat to Silk® high protein milk protein is 4.6, and when cocoa nonfat to NFDM protein is 9.2. The protein portion of the milks and extracts, and not the fat portion, reduced bitterness. A chalky texture might also be observed in a coated particle with lactose as the coating agent. The low solubility of lactose lent to its texture perception of chalky. When the coating agent was instead sugar with 20 DE CSS, maltodextrin or Fibersol-2, the coated particle did not taste chalky.

Accordingly, a coated particle may have about 66% to about 70% of sugars on a particle surface, preferably greater than about 30% and less than about 100%, preferably less than about 83%, which can be achieved partly when the core is insoluble such as cocoa or completely dispersible with a large, easily dispersible molecule such as whey protein. To control bitterness and astringency when cocoa is used as the core, the cocoa nonfat to protein ratio is preferably greater than 3, more preferably greater than 5, and most preferably greater than 7. A preferred choice of protein is a storage protein or a globular protein compared to largely insoluble proteins for water dispersions. In spray-dried particles, additionally milk protein with a mixture of globular and micellar proteins and pea protein, which is largely insoluble, are useful in reducing bitterness and can be used in fat-based confections. Globular proteins such as soy protein, rice protein, whey protein and fava bean protein might be preferable. Milk protein (at 1/10 ^th the weight of cocoa nonfat) might not be as effective as preferred proteins but can reduce the bitterness and astringency such that sweetness and cacao can be perceived. The off-flavors from proteins should be minimal, and proteins should taste bland. To spray dry powders, it might be preferable to reduce particle size to under 20 pm. Wet grinding prior to spray drying accomplishes this size reduction. Finally, sugar might be replaced with rice starch and produce an acceptable tasting, less sweet white chocolate. This addresses a problem with white paste (e.g., too sweet taste).

Notably, bitter compounds in cocoa include three groups. The first group is the methyl xanthans or alkaloids, such as theobromine, caffeine and 2,5-diketopiperazines. The second group is phenols (for instance, epicatechin and catechin) and procyanidins (DP 2-10). The third group is polyphenols, g-aminobutyric acid, polyphenol glycosides, and polyphenols amino acid conjugates. Thus, solutions to address bitterness in other bitter compounds might not necessarily work in cocoa. Table 19 shows a summary of examples for coated particles.

Table 19: Examples for Coated Particles (Spray Dried Particles, SDP)

Turning now to FIG. 7, a method 32 to form a coated composition including carbohydrate-coated particles is shown according to an embodiment. An aspect of the method 32 may include one or more aspects of the method(s) discussed above. For example, one or more aspects of the method 32 may include one or more aspects of the method 10 (FIG. 1), already discussed, or one or more aspects of the Examples 1-27, already discussed. In addition, one or more aspects of the method 32 may be automatically and/or manually implemented.

Block 34 combines a food particle and a carbohydrate to form a spray-drying mixture. A solvent, such as water, may be used to generate a slurry mixture. In one example, the water is potable water (e.g., deionized water, treated water, water that is safe to drink, etc.). In another example, the water is from a beverage (e.g., milk, a juice such as orange juice, etc.). Block 36 refines at least the food particle when the food particle does not have a predetermined average particle size. The predetermined size may be, for example, less than about 25 pm. When the food particle includes a combination of two or more types of food particles (e.g., cocoa powder and protein powder), block 36 may independently refine at least one of the two or more types of food particles to have the predetermined average particle size. Block 36 may also refine the mixture. Block 36 may further select one or more individual ingredients to have the predetermined average particle size and/or refine ingredients together, individually, or combinations thereof. Block 40 spray-dries to form the coated composition including spray- dried carbohydrate-coated particles. In one example, block 40 spray-dries a slurry mixture when the food parti cle(s) and/or ingredients have the predetermined average particle size.
