TECHNICAL FIELD

This invention relates to soy-based cheese, and more particularly to a soy-based cheese containing microbial cultures or acid.

BACKGROUND

Cheese making has relied on dairy milks as the major ingredient for more than 4000 years. Dairy cheese is usually made from curds formed from dairy milk. Dairy milks can readily be made to form curds suitable for making cheese by contacting the dairy milk with rennet (an aspartic protease which cleaves kappa-casein) at mildly acidic pH. Some cheeses, e.g., cream cheese, cottage cheese and paneer, are made without rennet. In the absence of rennet, dairy cheese may be induced to curdle with acid (e.g., lemon juice, vinegar, etc.) or a combination of heat and acid. Acid coagulation can also occur naturally from starter culture fermentation. The strength of the curds depends on the type of coagulation. Most commercially produced cheeses use some type of rennet (animal, vegetable or microbial-derived) in their production. Commodity cheeses or "processed cheeses" such as bulk cheddar, food-service mozzarella pizza and "cheese products," or "cheese foods" such as American cheese, American singles, Velveeta, and Cheese Whiz are typically produced from dairy-derived ingredients and other additives using industrial processes that little resemble traditional cheese making. A variety of non- dairy cheese analogs are available that contain soy products (e.g., soy milk powder, soy protein, or soy flour), oils, and various thickeners. However, the taste and texture of such products does not match that of dairy-based cheeses, and the amount of protein per serving is typically a third of that found in their dairy counterparts. Thus, there is a need in the art for an improved method and system for producing non-dairy cheeses.

SUMMARY

DETAILED DESCRIPTION

In general, this document provides methods and materials for producing meltable soy-based cheeses, i.e., the soy-based cheeses are able to become liquefied with heating. Broadly, the document provides methods for making soy based cheeses by incubating soy milk with one or more microbial strains (e.g., bacterial, yeast or mold strains) or acids, and optionally, a sugar (e.g., glucose or other sugar), one or more proteins (e.g., one or more isolated proteins, a protein isolate such as soy protein isolate, or the soluble portion of soy flour or soy protein isolate (referred to as the soluble protein pellet)) and/or flavor enhancers such as yeast extract or calcium pyruvate, for a sufficient period of time to obtain the desired H, which can range from about 4.5 to 6.4 (e.g., pH 5.4 to 5.7, 5.5 to 5.6, or 5.8 to 6.2). The length of the incubation period may vary depending on the temperature in which the soy milk and cultures are maintained. For example, the soy milk, microbial cultures, and optional ingredients can be incubated at temperatures ranging from room temperature (e.g., approximately 25°C) up to about 40°C (e.g., 25°C- 37°C or 25°C-40°C). It will be appreciated that the incubation time may vary depending on the size of the batch, amount of inoculum, and culture temperature.

Once the desired pH is reached, the resulting mixture of curds and whey (i.e., the liquid remaining after curdling) can be processed (e.g., by high speed shearing or blending to integrate the flavors, resulting in a soy based cheese with a mellower flavor) and one or more additional ingredients (e.g., oil, low methylester, amidated pectin such as pectin NH, and optional salts, starches, gums, coloring agents, sugars, flavorings, antioxidants, amino acids, quinoa, pyruvic acid or a salt form thereof, preservative, coconut milk, coconut cream, yeast extract, a dried yeast, protein, lecithin, a flour, a fiber, or cellulose) can be added. For example, the oil, salt, pectin, and coloring agent can be added to the blended mixture and the mixture heated to a temperature of about 60°C to about 100°C (e.g., at least 65°C, at least 70°C, at least 80°C, at least 85°C, at least 90°C, 60°C to 80°C, 65°C to 85°C, 70°C to 90°C, 75°C to 99°C, 80°C to 100°C, or 85°C to 100°C). One or more sugars and one or more flavorings then can be added to produce the soy-based cheese. Cheese molds can be used to form the soy-based cheese to the desired shape.

In some embodiments, the curds and whey can be separated and the individual components processed. For example, the curds and whey can be separated by draining the whey from the curd. For example, the mixture of curds and whey can be heated (e.g., 70°C to 90°C, 75°C, 80°C, or 85°C) to aid the separation of the curd from the whey and to reduce the number of viable microorganisms. The curds and whey can be combined in various ratios ranging from 50:50 curd:whey to 80:20 curd:whey (e.g., 60% curd : 40% whey; 65%> curd : 35%> whey; 70%> curd: 30%> whey, or 75%> curd : 25%> whey). In some embodiments, the curd may be combined with water instead of whey. A low methylester, amidated (LMA) pectin, an oil, and one or more optional ingredients (e.g., a salt, a starch, sugar, coloring agent, and/or a preservative such as sorbic acid) can be added to the curd: whey combination and the resulting mixture cooked to a temperature between 60°C and 100°C (e.g., at least 65°C, at least 70°C, at least 80°C, at least 85°C, at least 90°C, 60°C to 80°C, 65°C to 85°C, 70°C to 90°C, 75°C to 99°C, 80°C to 100°C, or 85°C to 100°C) with blending. One or more flavorings can be added to the cooked mixture then blended to obtain the soy-based cheese. Cheese molds can be used to form the soy-based cheese to the desired shape.

As described herein, the color, texture, and/or flavor of the soy-based cheese is similar to American process cheese and has similar melting characteristics and gooeyness, as well as a similar dairy character (e.g., buttery, cheesy, and milky). The soy-based cheese can be sliced, grated or cubed, and used, for example, to create grilled soy-cheese sandwiches, soy-cheese sauce (e.g., for macaroni and cheese), nachos, and/or soy-cheese burgers.

In some embodiments, soy protein isolate is used as the optional protein source when making the soy-based cheese. Soy protein isolate refers to the proteins extracted from defatted soy flour and is commercially available from many sources. In some embodiments, insoluble material (e.g., insoluble proteins or other insoluble material) is removed from soy flour or soy protein isolate, and the remaining soluble portion of the soy flour or soy protein isolate is used to prepare the soy-based cheese replica.

Removing the insoluble material before making the soy-based cheese replica improves the appearance (including both color and texture) as well as improves the mouth-feel of the soy-based cheese.

In embodiments in which the optional proteins are used in making the soy-based cheese, the protein content can be similar or more than that of a dairy based American cheese single. In some embodiments, the soy-based cheese can have a protein content that is similar or more than that of a dairy based American cheese (e.g., a block of dairy based American cheese or a dairy based American cheese single), and can have a carbohydrate content and/or a fat content that is similar or less than that of a dairy based American cheese (e.g., a block of dairy based American cheese or a dairy based American cheese single). For example, a soy-based cheese can have a protein content that is similar or higher than that of a dairy based American cheese, with a fat content that is less than that of a dairy based American cheese and a carbohydrate content that is similar to that of a dairy based American cheese. For example, a soy-based cheese can have a protein content that is similar or higher than that of a dairy based American cheese, with a carbohydrate content that is less than that of a dairy based American cheese and a fat content that is similar to that of a dairy based American cheese. For example, a soy-based cheese can have a protein content that is similar or higher than that of a dairy based American cheese, with a carbohydrate content and a fat content that is less than that of a dairy based American cheese. Typically, a dairy based cheese has a protein content of 18%, a carbohydrate content of 8%, and a fat content of 23%. For example, a soy-based cheese can have a protein content between 10%> and 20%> such as 10% and 19%, 10% to 15%, 15% to 20%, 15% to 19%, 15%, 16%, 17%, 18%, 19%, or 20%. For example, the soy-based cheese can have a carbohydrate content between 4% and 8% (e.g., 4% to 7%, 5% to 6%, 4%, 5%, 6%, or 7%). For example, the soy-based cheese can have a fat content between 16%> and 23% (e.g., 16%> to 18%, 19% to 22%, or 20% to 22%).

The invention will be further described in the following examples, which do not limit the scope of the invention described in the claims.

EXAMPLES

EXAMPLE 1

A meltable soy-based cheese was prepared using the following ingredients:

a) soy milk composed of soybeans and water (no other additives)

b) glucose

c) bacterial cultures: strains Streptococcus thermophilus (ST) (as TA61 , a commercial mix) and Staphlococcus x losus (SX)

d) I . MA pectin (pectin NH)

e) potato starch

f) salt g) canola oil

h) fructose

i) annatto

j) natural flavor

One liter of soy m lk (SunOpta organic soy base) was heated to 30°C in a clean sanitized container, and glucose was added to 50 mM (0.9%) along with cultures of SX and ST (each at a starting cell density of 1.25 x 10 7 cfu/ml). The mixture was incubated until a pH of 5.5 +/- 0.1 was reached. The incubation typically takes 3-6 hours to reach the target pB. (At this point, the coagulated soy milk can be placed on ice and refrigerated for up to 24 hours, before proceeding. pH may drop a few tenths of a percent during this time.) The mixture was transferred to a food processor and sheared/blended for 3 minutes, then pectin NH at 3.2%, potato starch (Eliane 100) at 0.4%, salt at 1.4%, canola oil at 14%, and annatto at 0.08% (or as needed to achieve desired orange color) was added and the mixture blended again in the food processor for an additional 2 minutes. After blending, the mixture was transferred to a pot and boiled for about 2 minutes per each 200 ml volume. This step allows the pectin NB to dissolve and also acts as a "kill step" to reduce the inoculated bacterial count. The pot was removed from the heat, and 0.09% fructose and 0.18% glucose (for added sweetness) was whisked into the mixture. At this point, due to evaporation during boiling, the volume of the mixture is about 70% of the starting volume. The mixture was transferred to a food processor and cooled to about 70°C, and then coconut cream at 10%, butanoic acid in oil at 0.01 %, 2,3 butanedione in oil at 0.0003%), gamma- undecalactone in oil at 0.00003%, and acetoin in water at 0.015% was added and the mixture blended for an additional minute to incorporate flavors into the mixture. Other combinations of natural flavors and/or artificial also can be used to flavor the cheese. The blended mixture was poured into cheese molds, and immediately covered with a plastic lid or wrap. The molds were refrigerated overnight to several days then removed. Once removed from the molds, the soy-based cheese can be sliced, grated or cubed, and used, for example, to create grilled soy-cheese sandwiches, soy-cheese sauce, and/or soy-cheese burgers. As shown in FIG. 1, the soy-based cheese is meltable (325°F x 5 minutes). EXAMPLE 2

A soy-based cheese was prepared using the following ingredients:

a) soy milk, composed of soybeans and water (no other additives)

h) glucose

c) bacterial cultures: strains ST (as TA61, a commercial mix) and SX

d) LMA pectin (pectin NH)

e) potato starch

f) salt

g) canola oil

h) fructose

i) annatto

j) natural and artificial flavors

k) sorbic acid (or other preservative):

Fifteen (15) liters (L) of soy milk (SunOpta organic soy base) was heated to 30°C in two clean sanitized pots of 7.5 L each, in a heated water bath, and glucose was added to 50 mM (0.9%) along with cultures of SX and ST (each at a starting cel l density of 1.25 x 10 ' cfu/ml). The mixture was incubated until a pH of 5.5 +/- 0.1 was reached. The incubation typically takes 3-6 hours to reach the target pH. Once the desired pH was reached, the pots were transferred to a double boiler set-up, and heated until the soy-milk mixture reached 75°C. After holding at 75° C for one minute, the pots were removed from the heat source. The heating serves as a "kill step" (allowing us to maintain the mix ture in the refrigerator for at least one week) and aids in the separation of curd from whey. The mixture was transferred to cheese-drainmg bags, and the curd was allowed to separate from the whey until a 70:30 curd: whey ratio was achieved. The 70:30 curd/whey mixture can be stored covered in the refrigerator for up to one week.

A 10-lb (4, 5 -kg) cooker run was performed by blending the curd/whey mixture at -75%, pectin NH at 3.2%, potato starch (E!iane 100) at 0.4%, salt at 1.4%, canola oil at 14%, annatto at 0.08% or as needed to achieve desired orange color, glucose at 0.18%, fructose at 0.09%, and sorbic acid at 0.2% (optional, as a preservative) in a mixer (alternatively a food processor) until well-blended and smooth. The blending step can be up to 30 minutes in length. The entire mixture was transferred to a pre-heated steam- cleaned chamber of a 10-pound cheese cooker and the temperature brought up to 180°C by steam injection, with continuous mixing. The mixture was cooked for 4 minutes. The steam was turned off and flavors were added as follows (at the final concentrations shown): butanoic acid in oil at 0.01%, 5,6 decenoic acid in oil at 0.005%, and acetoin in water at 0.015%. The butanoic acid and 5,6 decenoic acid were added together in a 5 -mi volume of canola oil, and the acetoin is in 11.2 ml of water. The cooker was run for an additional minute without steam injection. Note that the steam injection contributes an additional ~5% water (or about 225 ml per 4.5-kg batch) to the mixture.

The cooked soy-cheese mixture was decanted and transferred to a mixer (e.g., KitchenAid), and sheared/blended at high speed for 5 minutes. This post-cooking blending step helps prevent syneresis of oil. The blended mixture was poured into cheese molds, and immediate!)' covered with a plastic lid or wrap. The molds were refrigerated overnight to several days, then removed. FIG. 2 contains a photograph of the soy- based cheese. Once removed from the molds, the soy-based cheese can be sliced, grated or cubed, and used, for example, to create grilled soy-cheese sandwiches, soy-cheese sauce, and/or soy-cheese burgers.

EXAMPLE 3

A soy-based cheese was prepared using the ingredients in Example 1 , with the following additions: calcium pyruvate, yeast extract, Earth Balance buttery spread, glycine, and mixed tocopherols. The presence of calcium pyruvate contributes to a milder, less sour cheese replica. Yeast extract promotes bacterial strain growth and contributes some savory flavor to the cheese replica. Glycine may reduce sourness in the soy cheese.

The soy cheese was prepared as described in Example 1 , with the calcium pyruvate (~pH 2) added to 10 mM final concentration and yeast extract added at 0.5%, at the same time the cultures were added. After the mixture reached the desired pH, the pectin NH at 3.2%, potato starch (Eliane 100) at 0.4%, salt at 1.3%, canola oil at 7%, and annatto at 0.2% (or as needed to achieve desired orange color), glucose at 10 mM, and glycine at 5 mM was added. After pulsing 10 times to mix in a mini-chopper, the mixture was blended for 1 minute, then transferred to a pot. The mixture was boiled for 2 minutes, and then the following ingredients were added: Earth Balance buttery spread at 7% and mixed tocopherols at 0.5% (0.75 mg in canola oil per 150 ml mixture). The mixture was whisked until blended and smooth, and then immediately poured into cheese molds, and covered in plastic wrap and refrigerated overnight. The soy-based cheeses were un-molded and transferred to plastic containers and wrapped in plastic wrap (FIG. 3) and returned to the refrigerator until used. The cheeses were smooth and shiny when unwrapped, and had a dairy cheesy aroma. The cheese replicas were sliced (FIG. 4), and shredded in a Cuisinart (FIG. 5).

EXAMPLE 4

A meltable plant-based soy-based cheese was prepared using the following ingredients:

a) soy milk, composed of soybeans and water (no other additives)

b) soy protein isolate (Supro XT 219D, Solae)

c) glucose

d) bacterial cultures: strains Streptococcus therrnophilus (ST) (as TA61 , a commercial mix) and Staphlococcus xylosus (SX)

e) LMA pectin (pectin NH)

f) potato starch

g) salt

h) coconut oil

i) coconut cream

j ) guar gum

k) fructose

1) annatto

m) natural flavors Soy milk (SunOpta organic soy base) was heated to 30°C in a clean sanitized container. Soy protein isolate (Supro XT 219D) was added at 15%, glucose was added to 50 mM (0.9%), and cultures of SX and ST were each added at a starting cell density of approximately 1.25 x 10 ' efu/rni. The mixture was incubated until a pH of approximately 5.6 was reached. The incubation typically takes 3-6 hours to reach the target pH. (At this point, the coagulated soy milk can be placed on ice and refrigerated for up to 24 hours, before proceeding. pH may drop a few tenths of a percent during this time.) The mixture was transferred to a food processor and sheared/blended for 1 minute, then coconut cream (Kara, 5%), coconut oil (Shay and Co., 15%) and annatto (0.1 - 0.2%) were added, and the mixture was pulsed to thoroughly blend. Next, Pectin NH at 3.2%, potato starch (Eiiane 100) at 0.4%, salt at 1.4%, guar gum at 0.3%, glucose at 0.2% and fructose at 0.1% were added and the mixture blended again in the food processor for an additional 2 minutes. (Note: guar gum also may be pre-hydrated in water prior to blending.) After blending, the mixture was transferred to a pot and boiled for about 2 minutes per each 200 mi volume, to achieve an approximate weight loss of 15% due to water evaporation. This step allows the pectin to dissolve and also acts as a "kill step" to reduce the inoculated bacterial count. The pot was removed from the heat, and its contents were transferred to a mixer. Flavors were added: butanoic acid in oil at 0.01%, 2,3 butanedione in oil at 0.0003%, gamma-undecalactone in oil at 0.00003%, and acetoin in water at 0.015%, and the mixture blended for 30 seconds to incorporate these flavors into the mixture. The blended mixture was poured into cheese molds, and immediately covered with plastic wrap. The molds were refrigerated overnight to several days. Once removed from the molds, the soy-based cheese can be sliced, grated or cubed, and used, for example, to create grilled soy-cheese sandwiches, soy-cheese sauce, and/or soy- cheese burgers. The protein content of the soy-based cheese (analysis by Silliker) was about 15 - 16%. Soy-based cheese prepared with added soy-protein isolate and guar gum has a more cohesive and gooey melt than otherwise comparable soy-based cheese prepared without added soy protein isolate or guar gum. FIG. 6 provides a representative photograph of a grilled cheese prepared with the soy based cheese of this example. EXAMPLE 5

A meltable plant-based soy-based, cheese with a protein content that matches that of dairy American cheese was prepared using the following ingredients:

a) soy milk, composed of soybeans and water (no other additives)

b) soy protein isolate (Supro XT 219D, Solae)

c) glucose

d) bacterial cultures: strains Streptococcus thertnophilus (ST) (as T.A61, a commercial mix) and Staphlococc s xylosus (SX)

e) LMA pectin (pectin NH)

f) salt

g) coconut oil

h) earsoSa oil

i) coconut milk

j) guar gum

k) sucrose

1) annatto

m) natural and/ or artificial flavors

Soy milk (SunQpta organic soy base) was heated to 30°C in a clean sanitized container. Soy protein isolate (Supro XT 219D) was added at 23%, glucose was added to 50 mM (0.9%), and cultures of SX and ST were each added at a starting cell density of approximately .1.25 x 10 7 cfu/ml. The mixture was incubated until a pH of approximately 6.2 was reached. The incubation typically takes 3-4 hours to reach the target pH. The mixture was transfen'ed to a food processor. The following ingredients were added, and the mixture was sheared/blended for 3 minutes: coconut milk (5%), coconut oil (14%), canola oil (4%), pectin NH (3.2%), salt (.1.4%), guar gum (0.01%), and sucrose (0.9%). After blending, the mixture was transferred to a pan set atop a pot of boiling water and heated until the mixture reached 80°C, and achieved an approximate weight loss of 4% ± 1% due to water evaporation. This step allows the pectin to dissolve and also acts as a "kill step" to reduce the inoculated bacterial count. (If moisture loss exceeds 5%, water may be added back to the mixture to achieve a final moisture loss of about 4%. ) The pot was removed from the heat, and its contents were transferred to a mixer. Flavors were added, followed by annatto (67% solution at 0.1%) and the mixture was blended for 3 minutes. The blended mixture was poured into cheese molds, and immediately covered with plastic wrap. The molds were refrigerated overnight to several days. O ce removed from the molds, the soy-based cheese can be sliced, grated or cubed, and used, for example, to create grilled soy-cheese sandwiches, soy-cheese sauce, and/or soy-cheese burgers. The protein content of the soy-based cheese is comparable to that of a dairy- based American cheese, Kraft American singles, but with slightly lower fat (and no cholesterol) and carbohydrates (see Table 1, nutritional analysis by Silliker Inc. for the daiiy based cheese).

1) natural flavors

Soy milk (SunOpta organic soy base) was heated to 30°C in a clean sanitized container. Glucose was added to 50 mM (0.9%), and cultures of ST and SX were each added at a starting cell density of approximate!)' 1.25 x 10' cfu/ml. The mixture was incubated until a pH of approximately 5.5 was reached. The mixture was transferred to a food processor. The following ingredients were added, and the mixture was

sheared/blended for 2 minutes: coconut cream (10%), coconut oil (16.4%), Pectin NH (3.2%), potato starch (Eliane 100) (0.4%), salt (1.4%), guar gum (0.1%), and annatto (0.2% of a 67% solution in water). After blending, the mixture was transferred to a pot and boiled for about 2 minutes per each 200 ml volume, with continuous whisking. This step allo ws the LMA pectin to dissolve, reduces the moisture content, and also acts as a "kill step" to reduce the inoculated bacterial count. The pot was removed from the heat, and its contents transferred to a blender. 0.09% fructose, 0.18% glucose and 0.33% natural flavors were added, and the mixture was sheared/blended for 1 minute. The blended mixture was poured into cheese molds, and immediately covered with plastic wrap. The molds were refrigerated overnight to several days.

Once removed from the molds, the soy-based cheese replica was sliced, packaged in plastic containers and shipped on ice, along with packages of Tofutti American soy cheese slices (ingredients: water, may contain one or more of the following oils: soy, corn or palm, non-GMO [tofu, soy protein), carrageenan, maStodextrin, vinegar, corn starch, calcium phosphate, potato flakes, salt, potassium phosphate, non-dairy lactic acid, adipic acid, soy, natural colors and potassium sorbate (added as a preservative)] to the sensor}' test site. 98 subjects were served the two sliced samples in random order, and then the two samples in the form of gril led cheese sandwiches (GC) in random order. A 9-point degree of liking (DOL) scale was used to rate the samples for overall liking, appearance, flavor and texture. A 5 -point DOL scale was used to rate purchase intent.

As shown in Tables 2 A. and 2B, the soy-based American cheese repfica (Test sample) was preferred to Tofutti when the two samples were compared as slices or as GC sandwiches. There was a significant difference (p<0.05) between the samples in DOL on overall liking (Test GC was rated higher than Tofutti GC and Test Single was rated higher than Tofutti Single), appearance (Test GC was rated higher Tofutti GC), flavor (Test GC was rated higher than Tofutti GC and Test Single was rated higher than Tofutti Single), texture (Test GC was rated higher than Tofutti GC and Test Single was rated higher than Tofutti Single) and purchase intent (Test GC was rated higher than Tofutti GC and Test Single was rated higher than Tofutti Single). The only non-significant difference between slices was for appearance.

1 ) natural & artificial flavors

Soluble soy protein was isolated from CHS Honeysoy flour using acid precipitation. Soy flour was suspended in water at a 1 :5 ratio. The pH of the mixture was adjusted to pH 8.0 using 2 N NaOH. The protein slurry was stirred for I hour at 4 °C. The insoluble starch and protein were removed using centrifugation at 15,000xg at 19 °C for 15 minutes. The insolubles (pellet) were di scarded and the pH of the supernatant was adjusted to pH 4.5 using 2 M H2SO4 to precipitate out the soluble protein. The supernatant was stirred for 1 hour at 4 °C. A second centrifugation (15,000 xg, 19°C, 15 minutes) separated the soluble protein (pel let) from solution. The pellet was stored at 4°C u til further use.

To prepare the soy-based cheese using the soluble protein pellet (SPP), the wet SPP (33.50%) recovered from the protein extraction was slowly added to soymilk (64.60%). Due to the large pH differences between the protein pellet (pH 4.5) and soymilk (pH 6.76) the pH was maintained between 6.0-6.8 using 2 M NaOH. An immersion blender was used to ensure a homogeneous mixture. The final pH of the mixture was 6.85. The mixture was stored overnight. The following day the pH was readjusted to pH 6.85 using 2N NaOH. The mixture was heated to 30°C in a water bath. Glucose (0.90 %) was added, followed by the bacterial cultures (~ 1 ,0 %, starting cel l density of 1.25 x 10 7 cfu/ml each for SX and ST). The mixture was incubated at 30-35°C until the pH reached 5.95, approximately 4 hours. The mixture was immediately put on ice to slow the microbial growth and maintain pH, and stored overnight at 4 °C.

The mixture then was added to a food processor and sheared for 1 minute. The dry ingredients (LMA pectin (3.20%), guar gum (0.10%), salt (1.40%) and sucrose (0.9 %)) were added and the mixture was sheared for 1 minute. The wet ingredients, coconut oil (13.0%) and coconut cream (5.00%), were added and the mixture was sheared for an additional minute or until ail ingredients were well incorporated. The mixture was heated over a double broiler until the temperature of the mixture reached 80°C. The hot mixture was then returned to a clean food processor and sheared for 30 seconds. The natural and artificial flavors (2.63 ,u.L/g of cheese) were added and the mixture was sheared for 1 minute. Finally the annatto (0.10 %>) was added and the mixture was sheared until the color was uniform, approximately 1 minute. The mixture then was poured into molds, covered and stored at 4 C . This soy-based cheese was meltable after heating to 70°C as demonstrated in FIG. 7.

The color of the soy-based cheese prepared with SPP was brighter, shinier, and closer in color to dairy American cheese (e.g., Kraft singles) than soy-based cheese prepared with soy protein isolate (SPI). Colorimetry confirmed that the sample made with SPP was brighter (L* = 71.96) and closer to Kraft (L* = 74.83) than the control (L* = 67.73), where L* of 0 = darkest black and L* of 100 = brightest white. A tasting of the two soy-based cheeses in the form of grilled cheese sandwiches demonstrated that using SPP instead of SPI yields a smoother, creamier mouthfeel.

EXAMPLE 8

Soy milk (SunOpta organic soy base) was heated to 30°C in a clean sanitized container. Soy protein isolate (Supro XT 219D) was added at 18% and glucose was added at 0.9%. A sample was removed for gas chromatography mass spectrometry (GCMS) analysis of the volatile flavor compounds present in the starting material, which was ~pH 7.0. Cultures of SX and ST were each added at a starting cell density of approximately 1.25 x 10 7 cfu/ml. The mixture was incubated at 30°C and samples were removed at various points for GCMS analysis including at pH 6.5, 6.2, 6.0, and 5.8, and after overnight incubation.

The GCMS data indicated that several dairy aroma compounds were created during the soy mixture fermentation, including acetoin, propanoic acid, 3-methyl-butanal, acetic acid, butanoic acid, and hexanoic acid. The signal intensity of each of acetoin, propanoic acid, 3-methyl-butanal, acetic acid, and hexanoic acid was similar to that found in a dairy American cheese (Kraft American singles). See Table 3.
