Thomas Gottemoller

BACKGROUND OF THE INVENTION Field of the Invention

The present invention is related to the field of processing techniques used in the manufacture of soyfoods. The invention provides methods for preparing a soya fiber particulate from dehulled soybeans. The invention can be used to obtain a soya fiber particulate having a particle size in a range of about 0.01 microns to about 100 microns, wherein at least about 50% to about 100% of the soya fiber particulate has a size in a range of about 0.01 microns to about 35 microns. The soya fiber particulate may be used alone or as an ingredient in food products. 2. Related Art

The soybean is the one of the few plant protein sources that provides all eight essential amino acids. Soy protein is of the highest quality, equal to that of meat and dairy products, but without the cholesterol and high levels of saturated fat. In addition, the soybean has a higher amount of protein than other beans. Research has revealed many possible health benefits that may be achieved from the consumption of food products containing soy protein. The bioactive molecules occurring naturally in soy protein have antioxidant activities, which enhance the immune system, the body's defense against a wide range of diseases. For example, soy protein may play a role in the reduction of the risk of developing cardiovascular disease, including preventing heart attack, stroke, and high blood pressure. Soy protein, which is contained within soya fiber particulates, may also play a role in the reduction of the risk of developing kidney disease, various cancers and diabetes. Soy protein may also help protect against the development of osteoporosis and promote weight management. Because of these and other potential health effects, the commercial demand for soya fiber particulates is expected to rise rapidly. Soymilk, an aqueous extraction of soybeans, is used as a base in a wide variety of products. There are already a few reported processing techniques used in the manufacture of soymilk. A traditional method for soymilk production involves cleaning and then soaking whole, undehulled soybeans in cold water, rinsing the soaked soybeans, grinding the rinsed soybeans with additional fresh water into a coarse slurry, heating and then centrifuging the slurry, retaining the soluble soymilk fraction and disposing of the okara residue, also described as soymilk pulp or cell wall debris.

One disadvantage of traditional methods for soymilk production is the presence of an undesirable beany flavor, odor, and color. In order to improve the flavor of soymilk, alternate methods include heating and/or blanching for the inactivation of the enzymes that are responsible for the undesirable beany flavor and subsequent extraction of soluble constituents. For example, U.S. Patent No. 4,039,696 describes a process for preparing a milk-like product from whole soybeans by hot aqueous alkaline blanching and centrifugation. U.S. Patent No. 4, 971,825 describes a process for producing soybean milk which involves crushing, rather than grinding, soybeans in aqueous hot medium followed by soy protein extraction. U.S. Patent No. 4,992,294 discloses a method of producing soybean milk by boiling soybeans and straining the boiled solution. U.S. Patent No. 5,945,151 describes a process for producing a soymilk which involves heating a soybean paste. U.S. Patent No. 4,186,218 describes a process of improving denatured soy protein by superheating and/or alcohol extraction.

Other methods for eliminating undesirable odors from soymilk include fermentation. For example, U.S. Patent No. 3,971,843 describes a process for eliminating a bean odor from a soymilk by fermentation and distillation under reduced pressure. U.S. Patent No. 4,664,919 describes a process for producing a liquid-like lactic acid soymilk drinks by inoculating filtered pulverized soybeans with Streptococus sojalactis bacterium.

Soymilk produced according to traditional methods has a grainy texture. Occasionally, this grainy texture is desirable. For example, U.S. Patent No. 6,413,557 describes a process for preparing a textured soya beverage which includes blending soaked, rinsed, and cooked soybeans with loose soybean hulls. However, a soymilk composition with a smooth texture and pleasant mouthfeel is usually preferable. In order to obtain a soymilk with a smooth texture, alternate methods include the addition of enzymes to soybeans to degrade proteinaceous, carbohydrate, and cellulosic constituents, preventing sedimentation. For example, U.S. Patent No. 3,941,890 describes a process for preparing soymilk from dehulled soybeans by microwaving and adding suitable enzymatic material. U.S. Patent No. 4,378,376 describes a process for producing a simulated milk protein product by forming a neutralized aqueous slurry of a soya protein material and dairy whey and then reacting the slurry with a proteolytic enzyme.

Other methods for obtaining a soymilk with a smooth texture include multiple or extensive grinding steps. For example, U.S. Patent No. 5,807,602 describes a process for making a finely divided soya product based on continuous milling, superheating and flash evaporation. This method obtains soya particles wherein 90% have a diameter of less than 85 microns and 50% have a diameter of less than 40 microns. U.S. Patent No. 4,194,018 describes a process of preparing a soya composition from soybeans yielding particulate in which the largest dimension does not exceed 40 to 300 microns. Finally, another disadvantage of traditional methods for soymilk production is that the full nutritional quality of the soybean is not maximized. In order to improve the nutritional quality of soymilk, alternate methods include the use of acid or acid salt to process soybeans; specifically to chelate various soybean components. For example, U.S. Patent No. 6,322,846 describes a process for preparing soymilk and beverage compositions from whole soybeans which involves the addition of at least one of an acid and/or an acid salt. U.S. Patent No. 4,389,425 describes a process for preparing a bovine milk substitute which includes grinding soybeans in the presence of an acidified water solution followed by homogenization, desludging, and extraction. Other methods for improving the nutritional quality of soymilk involve extraction and/or filtration. For example, U.S. Patent No. 3,995,071 describes a process based on the aqueous extraction of defatted soy flakes, basefϊcation, and the removal of insolubles. U.S. Patent No. 4,091,120 describes a process for preparing soya protein beverages by ultrafiltration purification and precipitation. All of these reported processes are unable to produce a soya fiber particulate that has, simultaneously, a very smooth texture, a high nutritional value and lacks a beany flavor. For example, while the process disclosed in U.S. Patent No. 4, 194,018 produces a soya composition of a somewhat improved texture, the largest dimension of the product does not exceed 50 to 300 microns, meaning that the composition still has a grainy mouthfeel and lacks the stability for the prevention of sedimentation of the soy fiber particulate during storage. Therefore, there is a great need for improved, economical processes that provide very smooth soya fiber particulates.

SUMMARY OF THE INVENTION The invention is based on the surprising fact that soybeans can be processed such that a soya fiber particulate having a particulate size in a range of about 0.01 microns to about 100 microns is obtained. The soya fiber particulate of the invention has a very smooth texture, because about 50% to about 100% of the soya fiber particulate has a particle size in a range of about 0.01 microns to about 35 microns. The invention utilizes, rather than disposes of, the okara, which contains high levels of fiber and also comprises iron, calcium, protein, carbohydrate, thiamin, riboflavm, and niacin. Therefore, in addition to its smooth texture, the soya fiber particulate of the present invention is of high nutritional quality. This utilization of the okara by the processes of the present invention is highly economical, due to the high disposal costs of okara incurred by other processes. Finally, the soya fiber particulate of the present invention lacks a beany flavor and has a high stability. The technology allows for the use of this soya fiber particulate alone or as an ingredient in food products.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are intended to provide further explanation of the invention as claimed.

The soya fiber particulate may be concentrated into a powder form by evaporation or by dehydration. Alternatively, the soya fiber particulate may remain in a liquid form. Spray drying: As used herein, the term "spray drying" means transforming a fluid medium into a dry-powdered or particulate form. This is achieved by atomizing the fluid into a drying chamber, where the liquid droplets are passed through a hot-air stream. The objective is to produce a spray of high surface- to-mass ratio droplets, and then to uniformly and quickly evaporate the water. Evaporation keeps product temperature to a minimum, so little high-temperature deterioration occurs.

The feed can be a solution, a suspension or a paste in the simplest form. The dried product can be powdered, granulated or agglomerated. The dry product form can be varied depending on the feed, dryer design and process conditions. Spray drying delivers a powder of specific particle size and moisture content regardless of the dryer capacity or product heat sensitivity. In a continuous operation, the spray-dryer delivers a highly controlled powder quality with relatively easy control.

Topping: As used herein, the term "toppings" is taken to include, for example, salad dressing, whipped toppings, sauce, soy sauce and gravy.

Stability: As used herein, the term "stability" refers to the ability of the fiber particulate to resist sedimentation and/or stratification which occurs due to separation of the fiber particles from the main liquid suspension. Thus, a fiber particulate or a product comprising the fiber particulate that is characterized as "stable" is one in which the fiber particles remain suspended in the main liquid suspension for the shelf life of the product.

EXAMPLES

EXAMPLE 1

Wet milling bean cracks

3500 grams of organic white hylum soybeans were cleaned. The beans were cracked and dehulled yielding about 3250 grams of bean cracks.

The bean cracks were added to 18,000 grams of 95°C water. The slurry was run through a Boston Shearpump Model BSP 37-3.

The resulting slurry was then run through two times a Premier Supermill SM 15. at 5.0 gallons per hour with 1.2-1.7 Zirconox beads at a mill speed of 2700 feet per minute. The product was then jet cooked at 115°C for 60 seconds, flash cooled under a pressure of 380 mm of mercury to a temperature of 82°C.

The product was then homogenized at 510 bar on the first stage and 34 bar on the second stage to a total of 544 bar of an APV Rannie 10.38 homogenizer.

The product was then spray dried on a tall form dryer with an air inlet temperature of 232°C and an air outlet temperature of 82°C.

Results gave a soymilk product after standard dairy processing that was smooth and without off beany, grassy, or oxidized flavors. The product was smooth in the mouth without being astringent or gritty.

The particle sizes of the soya fiber particulates were such that the mean particle size was about 22 microns and 90% of the particles were less than 44 microns.

EXAMPLE 2 Dry milling bean cracks The beans are cracked and dehulled yielding about 3250 grams of bean cracks.

The bean cracks are dry ground with a Bauermeister universal mill and the resulting powder is added to 18,000 grams of 95°C. The resulting slurry is then run through two times a Premier Supermill SM 1.5 at 5.0 gallons per hour with 1.2-1.7 Zirconox beads at a mill speed of 2700 feet per minute.

The product was then jet cooked at 115°C for 60 seconds, flash cooled under a pressure of 380 mm of mercury to a temperature of 82°C .

The product was then sprayed dried on a tall form dryer with an air inlet temperature of 232°C and an air outlet temperature of 82°C. Results gave a soymilk product after standard dairy processing that was smooth and without off beany, grassy, or oxidized flavors. The product was smooth in the mouth without being astringent or gritty.

The particle sizes of the soya fiber particulates were such that the mean particle size was about 24 microns and 90% of the particles were less than 45 microns.

EXAMPLE 3 Soya fiber particulate particle sizes Soymilk was made with the soya fiber particulate produced in Example 1. The size of particles in the soymilk was determined, as shown in Table 1. Table 1. Soymilk particle size

EXAMPLE 4 Whole bean soymilk stability and soy fiber particulate stability

The stability of the soymilk was demonstrated by centrifuging two soymilks. The first soymilk is produced as in Example 1, and then reconstituted ultra high temperature pasteurized at 140°C for 4 seconds, homogenized at 170 bar and cooled to 4°C. The second soymilk was a commercial product of similar composition but produced by dry grinding and had a particle size range between 0.5 microns to 350 microns. It was also reconstituted and processed as the first soymilk before testing for stability.

The stability test was made using an IEC Centra GP8 centrifuge. Samples were measured into 50-milliliter centrifuge tubes. The samples were placed in the centrifuge and centrifuged at 500 rpm for 5 minutes. The results show that the product produced by Example 1 (the first soymilk) does not show a significant amount of sedimentation whereas the commercial product produced by dry grinding (the second soymilk) showed 5% by volume sedimentation. The products were then examined under a light microscope. The product produced by Example 1 showed particles that were smaller and had voids while the dry ground commercial product showed larger particles that were more crystalline in structure.

EXAMPLE 5 Defatted soy flakes soymilk stability and soy fiber particulate stability

The stability of the soymilk was demonstrated by centrifuging a soymilk made with defatted soy flakes using the process described in Example 1. Defatted soy flakes (NUTRISOY 7B Flakes, commercially available from Archer Daniels Midland Company of Decatur, IL) are processed in the same manner as the bean cracks according to Example 1. Specifically, 15,000 grams of defatted soy flakes were mixed with 85,000 grams of 95°C water to produce a slurry. The resulting slurry was then run through two times a Premier Supermill SM 15. at 5.0 gallons per hour with 1.2-1.7 Zirconox beads at a mill speed of 2700 feet per minute. The product was jet cooked at 115°C for 60 seconds, flash cooled under a pressure of 380 mm of mercury to a temperature of 82°C. The product was then homogenized at 510 bar on the first stage and 34 bar on the second stage to a total of 544 bar of an APV Rannie 10.38 homogenizer. Next, the product was spray dried on a tall form dryer with an air inlet temperature of 232°C and an air outlet temperature of 82°C. To produce the soymilk product, the dried product was then reconstituted, ultra high temperature pasteurized at 140°C for 4 seconds, homogenized at 170 bar and cooled to 4°C.

Stability of the soymilk product was measured using an IEC Centra GP8 centrifuge. Samples were deposited into 50-milliliter centrifuge tubes. The samples were placed in the centrifuge and centrifuged at 500 rpm for 5 minutes. The results show that the product produced by this method with defatted soy flakes does not show a significant amount of sedimentation.

The product was then examined under a light microscope. The product produced with defatted soy flakes by Example 1 showed particles that were small and had voids.

EXAMPLE 6 Flax fiber particulate Other grains were also run using the procedure of Example 1. For example, 30 pounds whole flax seed was added to 300 pounds of 95°C water. The product was then ran through a shear pump which had three grinding heads. A shear pump is a rotor and stator type system which reduces the particle size to approximately 150-200 microns. The product is then ran through the bean mill, homogenized, pasteurized and spray dried. Upon reconstitution, the particles' size ranged between 0.04 microns and 95 microns with 80% of the particles being between 0.04 microns and 35 microns.
