LOW SODIUM MARGARINE SPREAD ENRICHED WITH PROBIOTICS

RELATED APPLICATIONS

[0001] This application claims benefit of U.S. Patent Application No. 12/970,862, filed on December 16, 2010, which is hereby incorporated by reference herein in its entirety.

FIELD

[0002] Provided herein are shelf stable low sodium compositions comprising a probiotic bacterium. The compositions have reduced levels of trans fats. Also provided are methods of preparing such compositions and use thereof.

BACKGROUND

[0003] A variety of relatively hard fat compositions, e.g., margarine, spreads, shortening, and frying fat, are formed from seed oils and vegetable oils. For example, plastic fat compositions such as margarine and low-fat spreads typically comprise an emulsion of an oil phase (typically including a liquid oil and a hard fat, which usually has been hardened by hydrogenation) with an aqueous phase, together with various emulsifiers, stabilizers, preservatives, and flavoring agents.

[0004] As a process of hydrogenation, unsaturated fatty acids can be converted from their natural cis configuration to their trans isomer form. Recent studies have indicated that trans-fatty acids may impact cardiovascular health more negatively than saturated fatty acids do. In part due to this recent research, consumers are becoming attentive to the trans-fatty acid content of their diets and many consumers are beginning to prefer products with lower trans-fatty acid content.

[0005] As reported in the literature, a diet consistent with high sodium intake augments the risk of cardiac, vascular, renal and cerebral diseases. It is therefore desired that the margarine compositions contain low sodium.

[0006] With the increasing interest from consumers in a healthy diet, it is also becoming important to provide different food products which comprise probiotics, such as bacteria, where the products have good longevity of the probiotics.

[0007] Thus, there is a need in the art to provide shelf stable low sodium reduced trans fat margarine compositions that comprise probiotics in amounts desirable for health benefits to the consumer but which do not comprise unacceptable, or health endangering, amounts of undesirable pathogens or spoilage yeasts or moulds. SUMMARY

[0008] In certain embodiments, provided herein are shelf stable compositions comprising a reduced trans base oil, an unhydrogenated oil, water, a low sodium sea salt and probiotics. In certain embodiments, the compositions provided herein have a shelf life of up to 6-8 weeks or more. In certain embodiments, the compositions further comprise additives, including, but not limited to emulsifiers, preservatives, flavoring agents, and coloring agents. In certain

embodiments, the compositions are margarine compositions.

[0009] In one embodiment, provided herein are methods for producing a shelf stable margarine composition comprising a reduced trans base oil, an unhydrogenated oil, water, a low sodium sea salt and probiotics.

[0010] In certain embodiments, the method of preparation comprises the step of providing a composition comprising a reduced trans fat base oil, an unhydrogenated oil, water, low sodium sea salt and one or more additives, mixing the composition, cooling the composition, adding a probiotic, and mixing the composition again.

[0011] In certain embodiments, the margarine compositions provided herein have lower levels of saturated fats and trans fats, and sodium. In certain embodiment, the margarine compositions provided herein are used in bakery products, e.g., cookies, cakes, pie crusts, breads and other products in place of conventional margarines.

[0012] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive.

Methods of Preparation

[0055] In certain embodiments, provided herein are methods of preparing the low sodium shelf stable margarine compositions comprising probiotics. In certain embodiments, the methods of preparation comprise the steps of mixing a reduced trans base oil, an unhydrogenated oil, water, a low sodium sea salt, and one or more additives to obtain an admixture, cooling the admixture, and mixing a probiotic to provide the margarine composition. During the first mixing step, the composition is brought to a molten state such that the admixture becomes homogenized. The order of adding the ingredients and heating the ingredients can be changed as required by a particular process. The ingredients can be added at ambient temperature, or at a higher temperature, depending on the particular system used, and it is intended that the claims appended hereto shall not be limited by the order of the heating and mixing steps. The molten

homogeneous composition is cooled, in one embodiment, with agitation, to promote a crystal structure that imparts the desired physical properties to the margarine. A heat exchanger, in one embodiment, a scraped surface heat exchanger, can provide the desired cooling with agitation.

[0056] In certain embodiments, the probiotic is added after the cooling step and prior to the second mixing step such that the composition is cool enough for the probiotic to survive and the probiotic is mixed thoroughly prior to the packaging of the composition. In certain

embodiments, the probiotic is added to the oil phase before blending with the water phase. In certain embodiments, the probiotic is added to the oil/water blend. In certain embodiments, the probiotic is added to the water phase prior to blending with the oil phase.

[0057] In certain embodiments, the probiotic is incorporated at a temperature ranging from about 90°F -120°F or about from 108°F -114°F. In certain embodiments, the probiotc is incorporated at a temperature of about 90, 95, 100, 105, 108, 110, 115 or 120°F.

[0058] In certain embodiments, a pin mixer is used to mix the probiotic. In certain embodiments, the probiotic is added prior to mixing with the pin mixer. The final composition is cooled in, for example a crystallizer. An exemplary flow diagram showing various steps in the method is provided in Figure 1.

[0059] The mixing of a reduced trans base oil, a vegetable oil, water, a low sodium sea salt, and one or more additives can be accomplished using techniques known in the art. In certain embodiments, the admixture can be then subjected to agitation by means of a scraped-surface heat exchanger known in the art of margarine manufacture. In certain embodiments, processing conditions within the scraped-surface heat exchanger can be adjusted to further promote the desired margarine properties. The scraper blades prevent any build-up on the cylinder of crystals and other large particulates that can reduce thermal exchange and increase run time. A number of different operating parameters in the scraped-surface heat exchanger can be modified in order to optimize the one or more properties of the margarine (e.g., hardness, melting). For example, the speed of the scraping blades, the pumping speed through the scraped surface heat exchanger, and the exit temperature from the heat exchanger can be modified to optimize the hardness of the margarine.

Beta- Carotene 0.002%

Water 38.12%

Low Sodium Sea Salt 1.00%

Sodium Benzoate 0.10%

Lactic Acid 0.05%

Artificial Butter Flavor 0.069%

[0063] In Example 1, reduced trans base oil, unhydrogenated oil, hard fat and emulsifier were charged in a churn tank and blended together. A solution of water, low sodium sea salt, sodium benzoate and lactic acid was added to the churn tank followed by addition of additives. The blend was transferred to a holding tank and cooled by passing through a crystallizer to obtain a soft spread margarine formulation.

Example 2: Initial stability study

[0064] An initial proof of concept stability study was conducted using the feasibility formulation of soft spread. Three 600 g batches of the soft spread were melted and 0.2% bifidum bacteria were added to each batch at a temperature of 110°F. Each batch was allowed to mix via a magnetic stir bar for 2-3 minutes and then crystallized in the ice cream maker. All samples were put into the freezer (-20°F) overnight and then put into their respective temperature environments, which were 40°F, 70°F and 85°F. Samples were pulled every 2 weeks up to duration of 10 weeks.

[0065] The data observed from the initial stability study is shown in Table 2 and Figure 2.

*HoBi = HOWARU® bifidobacterium (Danisco - Copenhagen, Denmark)

[0066] The data showed that the bifidobacterium survived within the soft spread during the ten weeks. The recommended amount of bifidobacterium that are to be present in order to convey health benefits to the consumer are 1 billion per serving size. The stability data shown in Table 2 and in Figure 2 display that the probiotics are stable and provide the recommended amount up to 8 week period. The samples that were stored at 70°F and 85°F were not successful in sustaining the necessary amount needed to pass on healthful benefits to the consumer.

Example 3: Temperature Tolerance Test

[0067] Four 200g batches of soft spread were melted and 0.2% bifidum bacteria was added once the samples reached their respective temperature. The temperatures analyzed were 90°F, 98.6°F, 110°F, and 120°F. The samples were then crystallized via an ice maker and placed in the freezer overnight. Samples were sent for bifido bacterium enumeration the next day.

[0068] The data in Table 3 shows that the bacteria incorporated at temperatures ranging from 90°F -120°F remain fairly stable if crystallized immediately after mixing for 2 minutes.

[0069] The calculations of product inoculation were based off of approximated colony forming units present per gram; however due to the batch to batch variability of the probiotics the colony forming units may be higher at any given sampling. The approximate inoculation colony forming unit count at 0.20% usage was 600 million; the average colony forming units seen at a 0.20%> usage level based upon time zero data from various studies conducted was 828.2 million.

Example 4: Processing Temperature Test

[0070] Six 600g batches of soft spread were melted and had bifidum bacteria added once the samples reached their respective temperatures of either 110°F or 120°F. The samples were held at those temperatures while mixing and approximately lOOg of each batch were pulled and crystallized via the ice cream maker at time zero, ½ hour, 2 hours, and 4 hours. The samples were stored in the freezer overnight and then sent for bifidobacterium enumeration the next day.

[0071] The data provided in tables 4-1, 4-2, and 4-3 show the survival rate of

bifidobacterium when processed at both 110°F and 120°F for an extended amount of time.

[0072] Table 4-1 provides data using bifidobacterium at a 0.15%. The bacteria have a higher survival rate at 110°F, at 120°F, a low survival rate was observed.

Table 4-1 : Processing temperature data using 0.15% bacterium

[0073] Table 4-2 provides data for the processing temperature at 110°F, with an increased amount of bifidobacterium (0.25%) in order to compensate for any loss during processing as well as to maintain the recommended intake amount of at least 1 billion per serving. The data show that the bacterium withstands the recommended amount up to the 2 hours.

1/2 Hour 1,400,000,000 186.67%

2 Hour 1,200,000,000 160.00%

[0074] Due to the excellent survival rates of the 0.25% usage level of bacterium, the amount was decreased to 0.2%> to ensure not to over inoculate the product. Table 4-3 provides data using 0.20% of bacterium. The data follows the overall trend of gradual decline in bacterium present when held at 110°F for up to 4 hours. However a sharp decline was observed in the 4th hour pull. Without being bound to any particular theory, it is believed that the decline was due to an increase in temperature past 110°F. Since the study was conducted lab scale, magnetic stir bars were used which were not able to keep the complete blend product moving to avoid the setting up of product which in turn required additional heat to be applied to re -melt. This issue was not observed with the oil phase and aqueous phases

Table 4-3: Processing temperature data using 0.20% bacterium

[0075] The data has shown in tables 4-1, 4-2, and 4-3 indicates that the bacteria can withstand the temperature of 110°F for extended time periods.

Example 5: Phase Incorporation Stability Study

[0076] A phase incorporation stability was conducted in which three 500g batches of soft spread were prepared and 0.2% bifidum bacteria incorporated at different phases. The different phases consisted of i) bifidobacterium added once the oil and aqueous phases were combined prior to votation, ii) bifidobacterium added in the oil phase, and iii) bifidobacterium added in the aqueous phase. The complete blend samples were crystallized after the addition of

bifidobacterium and then placed in the 40°F environment. Samples were pulled every 2 weeks up to the 8th week.

[0077] The data shown in table 5 represent the shelf life stability of the bacterium when the bacterium was added at different stages of production. The complete blend represents the bacterium being added as the final ingredient to the soft spread; the other two incorporations phases represent the bacterium being added either at the oil or aqueous phase.

Table 5: Phase Incorporation Stability Study Data using 0.2% bacterium.

[0078] The data show that the bacterium is more stable upon being added in the oil phase; however other data from other tests have shown that addition of bacterium in the complete blend is also stable. Thus incorporation of bacterium in either the oil phase or complete blend is acceptable.

Example 6: Pilot Plant Run Stability Study

[0079] A pilot batch of soft spread was produced were the probiotic was added as the final ingredient. The bifidobacterium were added to the product once the oil and water phases were combined at a 0.2%> usage level. Samples were pulled from 15 lb cubes every 2 weeks up to the 10th week.

[0080] The optimal processing temperature was found to be 110°F; the optimum range was 108°F to 114°F. Additionally, mixing of the product required enough agitation to keep the product moving so that it does not set up. The free-wheeling speed of the agitators used via pilot plant trial were 1,530 rpm with a 4" mixed flow impeller and 715 rpm with a 8" 4 blade hydro foil impeller. The rpm's noted did not include the resistance given by the product. Example 7: Application Survival Study

[0081] The functionality of the Bifidobacteria was tested upon being spread onto a warm surface such as toast, bagels, and English muffins. The three different brands of the most commonly used toasters that were used to prepare the samples were Kitchen aid KMTT200®, Proctor-Silex®, and Oster Counterforms 6335®. The temperature of the toast, bagels, and English muffins were observed 4 times for each application time interval; and the temperature was observed for three different toasters. This allowed us to identify the average temperature of the food item at a given time interval. The time intervals that were observed were time zero, 30 seconds, 1, 2, and 5 minutes. The soft spread was then be spread onto the food items at there appropriate time interval which represents a given temperature. Each sample had 7g of spread applied to the food item. The samples were then placed in the freezer and submitted for bifidobacterium enumeration.

[0082] The application survival study data shown below in tables 6-1, 6-2, and 6-3 represents the survival rate of bacterium in the spread upon typical consumer use.

Table 6-1 : Application Survival Study using Oster Counterforms 6335® toaster.

Table 6-2: Application Survival Study using Kitchen aid KMTT200® toaster.

Table 6-3 : Application Survival Study using Proctor-Silex® toaster

[0083] The overall trend observed showed that the bacterium had a higher survival rate upon allowing the food item to cool briefly prior to spread application. The outliers present within the tables may be attributed to laboratory error.

[0084] The data shown in tables 6-4, 6-5, and 6-6 represent the average temperature of the food item as its respective time interval.

Table 6-4: Average Temperatures of Food Items using Oster Counterforms 6335® toaster.

Table 6-5: Average Temperatures of Food Items using Kitchen aid KMTT200® toaster

Table 6-6: Average Temperatures of Food Items using Proctor-Silex® toaster

[0085] The data shown in tables 6-1 through 6-6 provide a direct correlation between the increase in survival rate based upon a typical temperature of a given food item.

Example 7: Environmental Stress

[0086] Approximately 150 grams of soft spread was dispensed into twelve 4 oz plastic containers. Six containers each were placed at 70°F and 85°F in order to simulate a consumer leaving the soft spread out of a refrigerated environment for up to 6 hours. Samples were pulled at the following timeframes: ½, 1, 1 ½, 2, 4, and 6 hours. The samples were submitted for bifidobacterium enumeration to observe the survival of probiotics when in a stressed environment such as ambient or slightly above ambient temperatures.

[0087] Table 7-1 provides data for probiotics in each sample.

Table 7-1 : Environmental stress stability of soft spread with probiotics added as final ingredient at a 0.2% usage level.

[0088] Data in Table 7-1 shows that the probiotics in the soft spread are stable and can withstand the environmental stress of being left out of the 40°F environment thus being able to continue to provide the healthful benefit to the consumer.

Example 8: Sensory (Triangle) Panel

[0089] A hot triangle panel was conducted comparing the soft spread to the soft spread with probiotics added. The triangle panel was conducted using freshly prepared biscuits; only the tops were used in the panel to avoid any browning off-notes that may be present from the bottom of the biscuit. The biscuit tops had 7g of spread applied to them. At a significance level of 95%, the soft spread with probiotics did not have a significant difference from the soft spread without probiotics.

Example 9: Pilot Plant Final Ingredient Stability Study

[0090] The bifido bacteria were added to the product once the oil and water phases were combined at a 0.2%> usage level. Samples were pulled from 15 lb cubes every 2 weeks up to the 10th week.

[0091] The stability data is provided in table 9-1. Table 9-1 : Stability of soft spread with probiotics added as final ingredient at a 0.2% usage level

[0092] The stability data shown above in table 9-1 and in figure 3 display that the probiotics are stable when incorporated as the final ingredient and provide the recommended amount of probiotics needed to convey health benefits up to the 6 week period.

Example 10: Pilot Plant Phase Incorporation Stability Study

[0093] The data observed from the initial stability study showed that the bifidobacterium survive within the soft spread during ten weeks of storage at 40°F. To investigate the possible advantages and disadvantages of incorporating probiotics at different phases during processing a pilot plant batch was produced in which probiotics were added in the oil and water phase.

[0094] The stability data is shown below in table 10-1.

Table 10-1 : Stability of soft spread with probiotics added in oil & water phases at a 0.2% usage level.

[0095] The stability data shown in table 10-1 and in figure 4 display that the probiotics are more stable when incorporated in the water phase and provide the recommended amount of probiotics needed to convey health benefits up to the 14 week period.
