Abstract
Description
[0001] This application is a divisional application of the Chinese invention patent application with the application date of January 9, 2017, application number 201780015627.6, and invention name: "Product analogs or components of such analogs and preparation processes thereof".
[0002] CROSS-REFERENCE TO RELATED APPLICATIONS
[0003] This application claims the benefit of priority to U.S. Provisional Application No. 62 / 276,030, entitled Dairy Product Analogs and Processes for Making Same, filed January 7, 2016, and U.S. Provisional Application No. 62 / 326,403, entitled Dairy Product Analogs and Processes for Making Same, filed April 22, 2016. All of the above-related applications are incorporated herein by reference in their entirety. In addition, other references or publications cited in this disclosure are also incorporated herein by reference in their entirety. Field of the Invention
[0004] The present disclosure relates to food products that are substantially or entirely derived from non-animal sources, but have color, flavor, nutritional content, and / or other qualities similar to dairy products and / or other foods. The present disclosure also provides a process for producing such dairy-like foods and / or other similar foods. Background of the Invention
[0006] Vegetarian and vegan diets offer many benefits to individual consumers and to the world's food needs. Such benefits include healthy nutrition (e.g., lower saturated fat, no cholesterol), no ethical or religious dietary conflicts, fewer negative environmental impacts (e.g., fewer greenhouse gases produced in production), and more efficient use of resources (e.g., less water used in production).
[0007] Dairy-like food products and other types of similar foods derived from soy, coconut and almonds are readily available to consumers. The demand for these vegetarian / vegan alternatives to dairy products has been exacerbated by consumer intolerance to certain dairy ingredients. However, the acceptance of milk substitutes and other similar food substitutes has been relatively low. This may be due to a small extent to the increased intolerance experienced by consumers to the ingredients of these foods (e.g., allergy to soy protein). To a large extent, the appearance, flavor and / or mouthfeel of commercially available milk substitutes and other similar food substitutes are not attractive to consumers. In addition, many commercially available milk substitutes do not contain the same protein and fat content as dairy products and therefore have lower nutritional value.
[0008] Therefore, the production of milk substitutes and other similar food substitutes from other natural sources is needed. However, many natural sources contain compounds that limit their application in food. For example, peas and other leguminous plants contain compounds that produce significantly different colors and / or flavors, which are unpleasant and difficult to mask with colorants and / or flavorings. These compounds may also affect the structure or stability of proteins and therefore affect the appearance, sensory and nutritional quality and shelf life of foods derived from such other natural sources.
[0009] Therefore, there is an unmet need for non-animal derived foods that have the color, taste, nutritional content and other qualities of dairy products and other similar food substitutes, do not challenge common nutritional sensitivities, and provide the consumer experience that consumers are accustomed to from dairy products and other similar food substitutes. The present disclosure provides such and related foods and refined protein components (protein components) or refined protein isolates (protein isolates, PI), and their production processes. The present disclosure is directed to solving these and other problems disclosed herein. The present disclosure is also directed to overcoming and / or improving at least one of the shortcomings of the prior art, which will become apparent from the discussion herein. The present disclosure is also directed to pointing out one or more advantages of using the products, methods and refined protein isolates and / or refined protein components disclosed herein.

[0120] Dairy Product Analogs
[0121] Certain embodiments are directed to food products comprising refined protein obtained substantially or entirely from non-animal natural and / or modified non-animal natural sources, but having color, flavor, nutritional content, and / or other qualities similar to dairy products.
[0122] In some embodiments, the dairy analogs provided herein are analogs of dairy milk. In other embodiments, the dairy analogs are analogs of foods that are usually derived from dairy milk, including but not limited to cooking milk, sweetened condensed milk, flavored milk, yogurt, cheese, smoothies, milk shakes, coffee cream, infant formula, diet drinks, nutritional supplement drinks, clinical nutritional drinks, beverage powders and frozen desserts (e.g., ice cream, soft ice cream, frozen yogurt, sundae ice cream, pudding, whipped toppings) or combinations thereof. In some embodiments, the dairy analogs are mainly, substantially or completely composed of ingredients derived from non-animal natural sources. In alternative embodiments, the dairy analogs are composed of ingredients that are partially derived from animal sources but supplemented with ingredients derived from non-animal natural sources. The dairy analogs provided herein can be prepared for human or animal consumption, including domesticated animals (e.g., dogs, cats), farm animals (e.g., cattle, pigs, horses), and wild animals (e.g., non-domesticated carnivores). The dairy analogs can be used for various purposes, including but not limited to the feeding and delivery of active ingredients (e.g., vitamins, minerals, nutrients, therapies).
[0123] The dairy analogs provided herein have one or more of the advantages discussed in this disclosure. For example,
[0124] 1. The dairy analogue is not derived from animals or is not primarily derived from animals and can therefore be produced in a more sustainable manner;
[0125] 2. The dairy analogs can be produced from a wide variety of non-animal natural sources (e.g., legumes, grains, flax), thereby expanding their nutritional content and opening up the possibility of local sourcing of ingredients in areas where crops currently used to make dairy analogs cannot be grown;
[0126] 3. The dairy analogs provide nutritional qualities similar to or better than similar dairy products;
[0127] 4. The dairy analog provides similar or superior levels of protein, carbohydrates, vitamins, minerals, and / or other health benefits compared to dairy milk [e.g., whole milk, 2% milk, 1% milk, skim milk, or other dairy milk] (e.g., the dairy analog may contain equal or higher levels of protein, about 75% or lower levels of saturated fat, about 25% or lower levels of sugar, and / or equal or higher levels of calcium; or
[0128] The yogurt product analogs may contain about 50% or less protein levels, about 75% or less saturated fat levels, and / or greater than 25% or less sugars, and equal or greater levels of calcium compared to dairy yogurts [e.g., whole yogurt, 2% yogurt, 1% yogurt, nonfat yogurt, or other dairy yogurts]; and / or
[0129] 5. The dairy analogs are produced to have substantially lower levels and / or no certain ingredients that are less favorable to the general health of consumers (e.g., total sugars, saturated fat, total fat and / or cholesterol) or certain ingredients that are less favorable to the health of a small number of consumers (e.g.,
[0130] lactose).
[0131] One feature of the dairy product analogs provided herein is that they can have a color that is similar or substantially similar to the analogous dairy product. The color of a food product can be determined, for example, using a colorimeter or spectrophotometer capable of measuring light reflectance and L*a*b color space (see, for example, Jovanka et al., (2008) Color Changes of UHT Milk During Storage, Sensors 8(9):5961-5974; Zare et al. (2013) Probiotic Milk Supplementation with Pea Flour: Microbial and Physical Properties, Food and Bioprocess Technology 6(5):1321-1331; Sanz et al., (2008) Yogurt enrichment with functional asparagus fibre, Effect of fibre extraction method on rheological properties, colour, and sensory acceptance. European Food Research and Technology. Vol. 227(5):1515-1521; Brewer and Rankin (1998) Color of Nonfat Fluid Milk as Affected by Fermentation. Journal of Food Science. 63(1):178-180). The dairy analogs provided herein have a color defined as having an L* value of at least about 70, an a* value between about -1.5 and about +1.5, and a b* value between about -12 and about +12, as measured according to the method disclosed in Example 6. Alternatively, the color of the food product can be evaluated by a human sensory panel.
[0132] The dairy analogs provided herein may also have flavors similar to similar dairy products, and / or flavors similar to or superior to existing alternative dairy products (e.g., soy milk, almond milk). The flavor of a food product may be evaluated, for example, by a variety of different methods, including but not limited to blind tasting performed by a human inspector or a human sensory expert.
[0133] Compared with similar dairy products, the dairy analogs provided herein can include less, similar or greater amounts of protein. In some embodiments, the dairy analogs include by weight between about 0.01% and about 40%, between about 0.5% and about 30%, between about 1% and about 20%, between about 1% and about 10%, between about 1.5% and about 10%, between about 2% and about 8%, between about 1% and about 3%, between about 2% and about 5%, or between about 3% and about 7% of the protein obtained from non-animal natural and / or modified non-animal natural sources. In some embodiments, the dairy analogs include at least 0.01%, 0.5%, 1% 1.5%, 2%, 3%, 5%, 7%, 10%, 15%, 20%, 30% or 40% (weight) of protein obtained from non-animal natural and / or modified non-animal natural sources. In some embodiments, in the dairy analog, the ratio of protein to lipid is about 1:5, 1:4, 1:3, 1:
[0134] 2, 1:1, 2:1, 3:1, 4:1, 5:1 or 10:1. The protein content of a food can be determined by a variety of methods, including but not limited to AOAC International reference methods AOAC 990.03 and AOAC 992.15 and combustion analysis (ISO 14891:2008). In some embodiments, the dairy analog has an amino acid profile that is similar or substantially similar to the analog dairy product. In some embodiments, the amino acid profile of the dairy analog is at least 50%, 60%, 70%, 80%, 90% or 95% identical (by weight) to the amino acid profile of the analog dairy product in terms of the type of amino acids and the total amount of each amino acid. In some embodiments, the amino acid profile of the dairy analog is at least 50%, 60%, 70%, 80%, 90% or 95% identical by weight to the amino acid profile of a protein preparation obtained from a non-animal source used to prepare the dairy analog, in terms of the type of amino acids and the total amount of each amino acid.

[0143] In some embodiments, the method is for producing a dairy milk analog, and may comprise one or more of the following steps, in sequence or not:
[0144] a) obtaining at least one lipid component;
[0145] b) obtaining at least one neutral color refined protein component from a non-animal natural and / or modified non-animal natural source;

[0147] d) emulsifying at least a portion of the mixture to provide a dairy milk analog;
[0148] The amounts and ratios of the at least one lipid and at least one neutral color refined protein component are thereby selected to provide a desired nutritional profile.
[0149] In some embodiments, the method is for producing a dairy milk analog, and may comprise one or more of the following steps, in sequence or not:
[0150] a) obtaining at least one lipid component;
[0151] b) obtaining at least one refined protein component from a non-animal natural and / or modified non-animal natural source;
[0152] c) blending the at least one lipid component and the at least one refined protein component with a water component to produce a mixture; and
[0153] d) emulsifying at least a portion of the mixture to provide a dairy milk analog;
[0154] The amounts and ratios of the at least one lipid and at least one refined protein component are thereby selected to provide a desired nutritional profile.
[0155] Methods for obtaining the at least one lipid component are known in the art. In some embodiments, the at least one lipid component is obtained from non-animal natural and / or modified non-animal natural sources. Methods for obtaining the at least one neutral-colored refined protein component from non-animal natural and / or modified non-animal natural sources are provided herein. In some embodiments, the lipid component and / or protein component are obtained as a concentrated slurry. In some embodiments, the lipid component and / or protein component are obtained in solid form. In some embodiments, the neutral-colored refined protein component is mixed with one or more other proteins before mixing with the at least one lipid component.
[0156] The water phase can be an aqueous liquid, including but not limited to purified water, tap water, bottled water, deionized water, mineral water or a mixture thereof.
[0157] The lipid, protein and water components can be mixed in various orders. In some embodiments, these three components are mixed simultaneously. In other embodiments, the lipid component is mixed with the protein component before the water component is introduced into the mixture. In other embodiments, the protein component is mixed with the water component before the lipid component is introduced into the mixture. In other embodiments, the lipid component is mixed with the water component before the protein component is introduced into the mixture.
[0158] Mixing of the lipid, protein and water components can be accomplished using a variety of mixing devices, such as mechanical stirrers and / or high pressure jet machines. These components can also be stirred or mixed manually. Mixing can continue until each component is evenly distributed in the mixture in fact.
[0159] In some embodiments, a carbohydrate component is further added. A wide variety of ingredients can be used as a carbohydrate component, including but not limited to starch, white sugar, flour, edible fiber and combinations thereof. Examples of suitable starch include but are not limited to maltodextrin, inulin, fructooligosaccharides, pectin, carboxymethyl cellulose, guar gum, corn starch, oat starch, potato starch, rice starch, wheat starch or a combination thereof. Examples of suitable flour include but are not limited to amaranth flour, oat flour, quinoa flour, rice flour, rye flour, sorghum flour, soy flour, wheat flour, corn flour or a combination thereof. Examples of suitable edible fiber include but are not limited to barley gluten, carrot fiber, citrus fiber, corn bran, soluble dietary fiber, insoluble dietary fiber, oat gluten, pea fiber, rice bran, head husks, soy fiber, soy polysaccharide, wheat gluten, wood pulp cellulose or a combination thereof. In some embodiments, the carbohydrate component does not include lactose or does not substantially include lactose. The carbohydrate component may be present in the water component before mixing. Alternatively, the carbohydrate component is added to the lipid and / or protein component or to a lipid, protein and water mixture.
[0160] In some embodiments, one or more other ingredients are further added. In some such embodiments, the one or more other ingredients are added to the water component before mixing. In other embodiments, the one or more other ingredients are added to the lipid and / or protein component or to the lipid, protein and water mixture. In some embodiments, the one or more other ingredients include calcium.
[0161] Emulsification can occur without additional mechanical energy, or mechanical energy is required (e.g., vortexing, homogenization, stirring, ultrasonic treatment or other suitable mechanical activities). When emulsification is assisted by a lower amount of mechanical energy (e.g., stirring in a conventional mixer under moderate shear between about 100 rpm and about 1,000 rpm), the average droplet size of the resulting emulsion is typically larger (e.g., at least about 75% of the droplets have a diameter greater than about 25 um). When emulsification is assisted by a higher amount of mechanical energy (e.g., homogenization in a high pressure [e.g., between about 35 bar and about 650 bar] 1- or 2-stage homogenizer [e.g., between about 1,000 rpm and about 10,000 rpm], or microfluidization homogenization [between about 500 bar and about 2,000 bar]), the average droplet size of the resulting emulsion is typically smaller (e.g., at least about 75% of the droplets have a diameter less than about 10 um). Nanoemulsion can be obtained by homogenizing in a microfluidizer or other suitable equipment. In some applications, in order to obtain a higher lipid emulsion, the lipid component can be gradually added during mixing. In some applications, heating can help emulsification. In some embodiments, emulsification is carried out at a temperature higher than room temperature, higher than 30°C, 40°C, 50°C, 60°C, 70°C or 80°C, between about 90°C and about 120°C, between about 30°C and about 60°C, or between about 40°C and about 50°C. Cooling is usually performed after heating. Emulsification can be monitored by taking out a sample of the mixture and analyzing it by methods such as microscopy, light scattering and / or refractometry.
[0162] The emulsion may have droplets of various sizes. In some embodiments, the emulsion is a polydisperse emulsion (i.e., an emulsion containing droplets with a wide distribution of droplet sizes). In other embodiments, the emulsion is monodisperse (i.e., an emulsion containing droplets with a narrow distribution of droplet sizes). In some embodiments, the emulsion is a microemulsion (i.e., a thermodynamically stable system in which droplets are dispersed in a continuous phase). In other embodiments, the emulsion is a nanoemulsion (i.e., a metastable [or kinetically stable] dispersion of a liquid in different immiscible liquids with a droplet size range of 1 nm to 100 nm). In some embodiments, the average droplet size of the emulsion is less than about 1,000 nm, less than about 750 nm, less than about 500 nm, less than about 250 nm, less than about 100 nm, or less than about 50 nm, between about 100 nm and about 800 nm, or between about 100 nm and about 300 nm. In some embodiments, droplet size is reduced to the lipid content of reducing emulsion and dairy milk analog provided herein.During emulsification, the degree of emulsification can be realized by changing some parameters and therefore the final texture of the emulsion can be controlled to a certain degree.The example of such parameter includes but is not limited to the type and / or quantity of lipid component, the type and / or quantity of protein component, the type and / or quantity of optional emulsifier, the quantity of mechanical energy used during emulsification, centrifugal or filtering technique, the pH of water component, the temperature during mixing, the quantity or its combination of optional salt in water component.
[0163] In some embodiments, the dairy milk analog is sterilized or pasteurized. Sterilization can occur by UV irradiation, heating (e.g., steam sterilization, combustion, or dry heating) or chemical sterilization (e.g., exposure to ozone). In some embodiments, sterilization kills more than 95% of microorganisms. For pasteurization, the dairy milk analog is heated to a certain temperature (e.g., between about 280°F and about 306°F) and kept at such a temperature for a period of time (e.g., between about 1 second and about 10 seconds). Suitable pasteurization steps are known in the field of food manufacturing and can be carried out and / or continued for multiple time periods at various temperatures. Pasteurization can be high temperature short time (HTST), "extended shelf life" (ESL) processing, high pressure pasteurization (HPP), ultra pasteurization (UP), ultra high temperature (UHT) or a combination thereof. A controlled cooling system can be used to cool the dairy milk analog quickly. In some embodiments, the dairy milk analog undergoes vacuum cooling to remove volatiles and water vapor after pasteurization.
[0164] In certain embodiments, the source and / or quantity of the component are selected to provide the composition of the appropriate level without the need for additional supplementation. For example, the use of the low-fat natural source from which a lipid component or a protein component is isolated can facilitate the production of the dairy milk analog that reduces fat. Such a low-fat natural source includes but is not limited to a partially defatted natural source. Alternatively, components can be extracted from natural sources and conventional or unconventional methods such as centrifugation or membrane separation methods can be used to remove lipids from the extract. Similarly, the careful selection of natural sources and the seasonal variation of the composition of the extracted dairy milk analog can provide other components of the appropriate level, including but not limited to vitamins, minerals, dietary fiber, antioxidants or a combination thereof. The level of the composition can be further adjusted by supplementing.
[0165] The dairy milk analog may optionally be dried to obtain a powder. Drying may be performed in any suitable manner, including but not limited to spray drying, dry mixing, coagulation, freeze drying, microwave drying, drying with ethanol, evaporation, refractory window dehydration or a combination thereof.
[0166] The dairy milk analogs provided herein can be used as a base for producing other dairy analogs having certain nutritional profiles. In some embodiments, such other dairy analogs are yogurt analogs. The method provided herein for producing yogurt analogs can include one or more of the following steps, in order or not:

[0305] Example 1 - Obtaining a Neutral Color Refined Protein Fraction from Pea Protein Isolate
[0306] Spray dried pea protein isolate (Now Sports PeaProtein powder, Bloomingdale, IL) was added to distilled water and the pH was adjusted to pH 8.5 with 1N NaOH while stirring for 60 min to a final solid concentration of 100 g / L. The extract was separated by centrifugation at 5,000 to 15,000 g for 10 min. The supernatant was retained and the precipitate was discarded. The supernatant was centrifuged again to clear it from the solids. The pea protein was then precipitated by adding 500 mM CaCl2 to a final concentration of 50 mM and adjusting the pH to 5.25 with 1N HCl. The mixture was mixed briefly. When formed, the white precipitate was separated by centrifugation at 5,000 to 15,000 g for 10 min. The supernatant was discarded and the precipitate was washed twice with water (1 N HCl at pH 5.25) (acidified water was added to the precipitate to a final dilution of 25-50x (~1-2 mL of solid precipitate was mixed in 50 mL of acidified water; briefly mixed; centrifuged as above, repeated). The protein yields obtained were as follows: 7% (weight) extracted protein; 70% (volume recovery) protein aqueous solution; 33-50% mass yield (after salt precipitation); and 95% mass yield (after acid washing). The color of the resulting protein paste was determined as described in Example 6; the L* value of the protein paste was 89.5, the a* value was 4.1, and the b* value was 9.6, and the calcium to protein ratio was 6% w / w. The relative emulsifying activity (Table 1) of the protein paste was determined as described in Example 7.

[0308] Example 2 - Obtaining a neutral coloured refined protein fraction from chick pea flour
[0309] Use hammer mill to grind dried chick pea to 30-100# mesh size to make chick pea powder. Add the chick pea powder to distilled water, adjust pH to pH 8.5 with 1N NaOH, and stir for 60min to final solid concentration of 100g / L. Separate the extract by centrifuging 10min at 5,000 to 15,000g. Keep the supernatant and discard the precipitate.

When formed, separate the white precipitate by centrifuging 10min at 5,000 to 15,000g. The supernatant was discarded and the precipitate was washed twice with water (1 N HCl at pH 5.25) (acidified water was added to the precipitate to a final dilution of 25-50x (~1-2 mL of solid precipitate was mixed in 50 mL of acidified water; briefly mixed; centrifuged as above, repeated). The protein yields obtained were as follows: 70% (weight) extracted protein; 70% (volume recovery) protein aqueous solution; 33-50% mass yield (after salt precipitation); and 95% mass yield (after acid washing), and a calcium:protein ratio of 5% w / w.
[0310] Example 3A - Obtaining a Neutral Color Refined Protein Fraction from Pea Flour
[0311] Pea flour was made by grinding dried yellow peas (Giusto Specialty Foods, LLC) to 100# mesh size using a hammer mill. The pea flour was added to distilled water, adjusted to pH 8.5 with 1N NaOH, and stirred for 60 min to a final solid concentration of 100 g / L. The extract was separated by passing the slurry through a decanting centrifuge. The supernatant was retained and the precipitate was discarded.

[0312] Example 3B - Obtaining Refined Protein from Pea Flour
[0313] Pea flour was made by grinding dried yellow peas (Giusto Specialty Foods, LLC) to 100# mesh size using a hammer mill. 10 kg of pea flour was added to distilled water, the pH was adjusted to pH 8.5 with 1N NaOH, and stirred for 60 min to a final solid concentration of 100 g / L. The extract was separated by passing the slurry through a decanting centrifuge. The supernatant was retained and the precipitate was discarded. The retentate was retained and the filtrate was discarded. The pea flour protein was then precipitated by adding CaCl2 to a final concentration of 10 mM and adjusting the pH to 4.5 with 6N HCl. The mixture was briefly mixed. When formed, a white precipitate was isolated using a disk stack centrifuge. The supernatant was discarded and the precipitate was washed with water (the water was titrated to pH 5.25 with 6N HCl). The yields obtained were as follows: 49% by weight of protein extracted from the pea flour, and 68% by weight of protein precipitated from the aqueous extract. This resulted in a final recovery of about 33% protein from the pea flour. The final mass of the refined protein isolate was 1.2 kg, containing 53% protein by mass (mass / dry weight %). The color of the emulsion produced from the protein paste was determined as described in Example 8; it had an L* value of 76.2, an a* value of -1.73, and a b* value of 1.2.
[0314] Example 4 - Production of Dairy Milk Analogs
[0315] A dairy milk analogue was produced, the composition of which is shown in Table 2.
[0316]
[0317] Cellulose gum and gellan gum are combined with evaporated cane juice in a dry blend. Sunflower oil is combined with DHA and lecithin to obtain an oil blend. Defoamer is added to water under high shear until dissolved, the neutral color refined protein component is added, and the mixture is mixed for 3 minutes at <1300rpm to obtain a liquid blend. Dipotassium hydrogen phosphate is added to the liquid blend, and the blend is mixed for another 1 minute. Dry blend, oil blend, mineral blend and flavoring are mixed together at >1,400rpm for 5 minutes to become a liquid blend. Record pH, and the blend is treated with microthermics for online homogenization (direct, 293F, 6.5 seconds, 2,500psi). The resulting product is collected and cooled, and then vitamins are added. The resulting dairy milk analog was determined as described in Example 6; the resulting dairy milk analog had an L* value of 75.9, an a* value of 0.2, and a b* value of 6.8; a protein content of 8 g per 8 oz serving; and a sugar content of 6 g per 8 oz serving. The taste was evaluated by a panel of panelists to see if it was superior to commercial almond milk and soy milk samples.
[0318] Example 5 - Production of Dairy Yogurt Analogs
[0319] A dairy yogurt analog base was produced, the composition of which is shown in Table 3.
[0320]
[0321] Combine corn starch / pectin blend with evaporated sucrose. Hydrate the neutral color refined protein component in 120°F water under high shear for 5 minutes. The pH of the hydrated neutral color refined protein component is adjusted to pH 7 with NaOH, then combined with corn starch / pectin / sugar blend under high shear and allowed to hydrate for another 30 minutes. Sunflower oil is added to the mixture under shear, and the mixture is heated to 140°F under constant stirring while covered with foil. The mixture is homogenized at 2,500psi (500psi Stage 2, 2,000psi Stage 1). Subsequently, the heating is increased to 200-205°F and maintained for 20min while maintaining stirring with a heat-resistant spatula. Finally, the mixture is covered with foil and left to cool to below 105°F. To 3,785.41 g of the dairy yogurt analog base, 1 g of Yogurtstarter Culture (Vivolac Soy 424) was added and the culture was incubated at 44° C. until pH 4.4-4.5 was reached. The resulting dairy yogurt analog had a low saturated fat content and no cholesterol compared to whole-fat yogurt, but a protein content similar to that of unfiltered whole-fat yogurt.
[0322] Example 6 - Method for determining the color of food
[0323] The color of the food was determined using a Datacolor 45S portable spectrophotometer (Datacolor, Lawrenceville, NJ, USA) using illuminant D65 and a viewing angle of 10 degrees. Calibration was performed using a reference tile and the results were expressed using the CIELAB system (determining L*-lightness, a* (green / red), and b* (blue / yellow)). The L*a*b values for a number of dairy products were determined and are listed in Table 4. The color of food analogs may also be determined using this method or other acceptable methods.

[0326]
[0327] Example 7 - Method for determining the relative emulsifying activity of a neutral colored refined protein fraction.
[0328] The neutral color purified protein fraction was dissolved in 0.3 M NaCl at 3.2% final protein concentration and 450 uL aliquots were added to each of three microcentrifuge tubes. A 0.3 M NaCl solution was used as a blank control, and a 0.3 M NaCl solution of bovine serum albumin (BSA; A2153, Sigma Aldrich) (3.2% final protein concentration) was used as a BSA standard. 50 uL of sunflower oil (Spectrum) was added to each microcentrifuge tube and vortexed for 15 minutes at setting 10 using a Genie Vortex and a foam tube adapter to produce an emulsion. Each tube was then placed on a stand and the emulsion was allowed to settle for 10-15 minutes. A 20uL aliquot of each emulsion (taken from the bottom of the tube, below any visible foam) was added to 480uL of 0.1% SDS solution, and the mixture was mixed by pipetting up and down 3 times (volume 300uL). Each sample was serially diluted 1:2 and 1:4 in 0.1% SDS. The absorbance at 500nm (A500) was measured for each sample as follows: using a 200uL aliquot of the sample, in a 96-well clear polystyrene plate, and using a Biotek Synergy H1 plate reader (programmed shaking for 1 minute to remove residual bubbles). The corrected A500 was calculated according to the following formula: Corrected A500 = (A500 sample - A500 blank) x dilution factor. The relative emulsification activity was calculated by dividing the average corrected A500 by the average corrected A500 of the BSA standard.
[0329] Example 8 - Process for isolating refined protein components and / or refined protein isolates from various flour and protein sources
[0330] The present embodiment relates to a process for producing a refined protein isolate or a refined protein component from a variety of plant protein sources. In the present embodiment, the analyzed plant sources include both leguminous plants and oilseeds. The present embodiment illustrates and quantifies the removal of various compounds (e.g., fat, carbohydrates, ions and / or small molecules) in the separation process, and evaluates the characteristics of the separated protein such as color, taste and functionality. In nine tested plant sources, the refined protein separation or refined protein component process is effective when separating clean refined proteins, and removes a considerable portion of carbohydrates, ions (except Ca) and small molecules. The process results in the production of white protein with a cleaner taste than currently comparable commercially available commercial proteins. The present embodiment is non-restrictive and the process, function and modification can be applied to one or more of other embodiments disclosed herein both qualitatively and quantitatively.
[0331] Plant Source
[0332] The plant sources tested included yellow pea (YPE), garbanzo bean (GAR), fava bean (FAV), white bean (WBF), kidney bean (NAV), soybean (SOY), sesame (SES), almond (ALM) and quinoa (QUI). Some commercial sources of protein used were: Pea Protein Isolate S85F (Roquette), source: Roquette; Puris Pea 870 (Puris), source: World Food Processing; Pea Protein Isolate 80 (Nutralliance), source: Nutralliance; and Soy Protein Isolate (Soy PI), source: Now Sports. The commercial sources of bean flours and oilseed flours used were Yellow pea flour (YPE) from Ingredion 1102; Garbanzo bean flour (GAR) from Bob's Red Mill; Fava bean flour (FAV) from Bob's Red Mill; White bean flour (WBF) from Bob's Red Mill; Navy bean flour (NAV) from whole navy beans from Bob's Red Mill, ground in a coffee grinder; Low fat soy flour (SOY) from Bob's Red Mill; Defatted sesame flour (SES) from Sukrin; and Defatted almond flour (ALM) from Sukrin.
[0333] Protein separation process
[0334] The refined protein separation process begins with a water extraction step, in which the plant source is mixed with water at a determined optimal pH for extraction. For extraction, preliminary tests for determining the optimal pH to solubilize plant proteins are described in the present disclosure, but other methods can also be used to determine the optimal pH. It should be understood that there may be one or more optimal pHs and / or one or more pH ranges that can be used in the embodiments disclosed herein. The aqueous phase is separated from the solids (starch / fiber) by centrifugation. The soluble protein is then precipitated by a combination of heating (60C), acid (pH reduced to 5.5) and CaCl2 addition (added to a ratio of 0.1g CaCl2 to g protein). The precipitated protein is separated by centrifugation and the supernatant is discarded. The separated protein is washed by mixing with tap water (30x dilution (weight)) and centrifuged again. The material from this final step is called refined protein isolate and is analyzed as described below. A schematic diagram of the process for flour type or protein isolate starting material is shown in Figure 1A . Figure 1A The steps used in the protein separation process for producing useful refined protein isolates and / or refined protein components for one or more of the embodiments disclosed below are schematically represented. Samples are prepared in duplicate according to the procedures described herein and certain process parameters (e.g., pH, temperature, and centrifugation speed) are kept constant or substantially constant; however, ranges of these parameters have been shown to be effective. In some embodiments, such as Figure 1B As outlined, the preliminary extraction step is bypassed.
[0335] In this example, an exemplary benchtop procedure (outlined in Figure 1B ) has the following steps:
[0336] 1.12% PPI loaded (weight) (90g PPI was brought to 750g with tap water)
[0337] 2. Mix on a mixing board until well combined.
[0338] 3. Raise pH to 9 with 6N NaOH and mix for about 5 minutes
[0339] 4. Add CaCl2 4M to reach a concentration of 30mM CaCl2
[0340] 5. Adjust pH to 4.6 with 6N HCl
[0341] 6. Centrifuge at 3500 rpm (2,200 g) for about 5 min. Discard the supernatant.
[0342] 7. Wash the precipitate with about 15x water (by weight).
[0343] 8. Centrifuge at 3500 rpm for about 5 min and discard the supernatant. The resulting precipitate is the final product.
[0344] In this example, the benchtop procedure for extracting refined protein isolate from flour consists of the following steps:
[0345] 1. If the alternative source is whole grains, grind them in a coffee grinder or pulverizer.
[0346] 2. 10% flour loaded (by weight, 250 g of flour and water added to bring it up to 2500 g).
[0347] 3. Mix on a mixing board until well combined.
[0348] 4. Adjust pH to 7 or 9 with 6N NaOH (use pH 7 for pulses and pH 9 for oilseeds, see Extraction pH Optimization).
[0349] 5. Centrifuge at 5000 rpm for about 5 minutes to separate. Collect the supernatant (extract). Discard the solid.
[0350] 6. If particles are still visible, pass the supernatant through another centrifugation (at 5000 rpm for about 5 min). If necessary, filter with a metal mesh.
[0351] 7. For sources with high fat content, the fat layer can be separated at this step. Pour the extract carefully to avoid the fat layer.
[0352] It should be understood that this embodiment is for bench preparation, and one or more steps and / or parameters can be changed to produce such useful refined protein isolates and / or refined protein components for larger or commercial quantities of useful refined protein isolates and / or refined protein components. The procedures set forth in this embodiment are exemplary, and other appropriate procedures can be used for both bench and commercial methods to obtain the refined protein isolates and / or refined protein components of the present disclosure.
[0353] Thereafter, the samples in this example were subjected to an exemplary CaCl protein precipitation process, comprising the following steps:
[0354] 1. Heat the extract in a water bath at about 63°C until the extraction temperature reaches 60°C.
[0355] 2. Based on the protein concentration, calculate the amount of CaCl2 4M that needs to be added to obtain a final ratio of 0.10 g CaCl2 / g protein.
[0356] 3. Add the corresponding volume of CaCl2 4M and adjust the pH to 5.5 (with 6N HCl) to precipitate the protein.
[0357] 4. Centrifuge at 5000 rpm (4650 g) for about 5 minutes.
[0358] 5. Pour off and discard the supernatant and collect the protein paste.
[0359] Thereafter, the sample in this embodiment undergoes an exemplary washing process, comprising the following steps:
[0360] 1. Resuspend the protein paste in 30x volume of water (by weight), mix with a rod homogenizer for 15 seconds, and adjust the pH to 5.5.
[0361] 2. Centrifuge at 4000 rpm (2970 g) for about 5 minutes.
[0362] 3. Pour off the supernatant and collect the protein paste. This is the final refined protein isolate. For each source, the optimization of protein extraction conditions
[0363] In this example, the extraction pH was optimized for each source. In general, for beans, pH 7 was a good compromise between good protein extraction yield and low extraction yield of other compounds (based at least in part on extraction color observations). For oilseeds, pH 9 had the greatest yield. The extraction pH used in the flour process at the time of the specific operation was 7 for beans and 9 for oilseeds. Figure 2 Shown is the protein (%) extracted from eight flour / protein isolate sources at increasing pH values.
[0364] Yield
[0365] This process was performed in duplicate on eight flour / protein isolate sources and the process described herein was used. This process was effective for the sources tested. The protein (%) solubilized and extracted from the flour (% extraction yield) varied in the range of 31-85% in the different sources, and the percentage of soluble protein precipitated from the extract (% precipitation yield) ranged from 21-71%. The overall yield from flour to protein isolate (% overall yield) ranged from 12-53%. For each source, the yield values were similar in two replicates. The final percentage protein in the paste varied in the range of 7-20% (weight) depending on the plant source. Figure 3The % yield (by weight) in duplicate at each step is shown for the eight sources tested (extraction, precipitation, overall). Table 5 shows the results of the experiments for the protein isolation process using eight different plant sources. The yield at each step of the process, the protein extracted from the flour (extraction yield), the protein precipitated from the aqueous protein extract (precipitation yield) and the total yield from the process (overall yield). The amount of protein in the final mash varies depending on the plant source.

[0367]
[0368] Refined Protein Macronutrients and Micronutrients
[0369] The following discussion shows that for this paradigm, the results of protein, fat, carbohydrate and starch content are functions of process steps. As discussed in the process description subsection, the starting raw material is a commercial flour / protein isolate made from various leguminous plants, oil seeds (defatted) or cereals. The commercial flour / protein isolate is then processed by water extraction, and the resulting supernatant is treated with CaCl2 and acid to solidify the insoluble portion, which is collected and analyzed. In general, the results are presented in the final recovered insoluble portion (exemplary refined protein isolate), with a considerable enrichment in protein content, a slight enrichment in fat, and a reduction in carbohydrates. Figure 4 It is shown that for the raw materials processed and tested, the % protein (protein weight / sample dry weight) generally increases from the starting commercial flour / protein isolate to the final protein isolate. This value is comparable to the protein value of commercial PI (measured by combustion using a LECO nitrogen analyzer). Figure 5 Fat levels generally showed a slight enrichment during the process, but it was noted that the fat to protein ratio decreased in the final protein isolate due to the increase in protein (fat was measured using AOAC 933.05). Figure 6 The carbohydrate mass percentage is shown as a function of the process step (mass / dry weight). In some cases, carbohydrates in the final product (final refined protein isolate) are undetectable. Oilseed defatted meal has lower carbohydrates than legume meal.
[0370] Figure 7The starch mass percentage is shown as a function of the process step (mass / dry weight). The starch reduction from the flour source (quinoa here instead of beans) is between 43% and 99% (from flour to final protein isolate). Once again, the oilseed meal has very low starch levels. With regard to the starch determination method used in this example, each sample was enzymatically digested (α-amylase (Sigma-Aldrich, AA306], amyloglucosidase (Sigma-Aldrich, A7095). Undigested samples were treated identically as controls. After incubation, the samples were vortexed and the supernatants were subjected to organic acid HPLC. The glucose in the undigested samples was subtracted from the glucose value in the digested samples. The net glucose concentration (weight) was back-calculated to find the original digested starch present in the sample. HPLC was performed on an Agilent 1200 HPLC instrument (using a 1260RID module). The analytical column was an Aminex 87-H column (Bio-rad, Hercules, CA] (equipped with a Micro-Guard Cation H cartridge (Bio-Rad)). The running buffer was 5 mM sulfuric acid (at a flow rate of 0.6 mL / min). The injection volume of the sample supernatant was 10 uL. The refractive index signal was observed for 30 minutes. For the analytes, the peak area was compared with an embedded five-point calibration (up to 30 g / kg).
[0371] Table 6 is a summary of the mass % (mass / dry weight) data of protein, carbohydrates, fat and starch for each replicate of each plant source tested:
[0372]
[0373] Ions (Ca, P, Na, K, Cl, ash)
[0374] Several ions that may impart flavor or nutritional content were measured during the process. Overall, the calcium content increased significantly during the process, which is by design. We coagulate the protein with calcium salts and the Ca++ ions become partially complexed with the protein and remain until the end of the process. Figure 8 The mass % calcium (mass / dry weight) showed an increase during the process, which was due to the complexation of Ca ions with proteins (measured using AOAC 984.27). There was a slight enrichment of phosphorus. Fig. 9 Phosphorus content was shown to be slightly enriched in the final refined protein isolate (measured using AOAC 984.27). Sodium and potassium ions were substantially washed out in the final refined protein isolate, which is at least partially due to the purification process. Fig.10 It was shown that sodium was generally removed or significantly reduced during the process (measured using AOAC 984.27). Fig.11It was shown that potassium was generally removed or significantly reduced during the process (measured by AOAC 984.27). Chloride ion was generally undetectable throughout the process (data not shown). Ash generally remained constant during the process (measured by AOAC 950.14A), such as Fig.12 Table 7 below provides a summary of the mass % (mass / dry weight) data of ions (Ca, P, Na, K) and ash for each replicate of each plant source tested:

[0380] Restore capability
[0381] Reducing power is a proxy measurement of phenolic acids and other reducing compounds. Phenolic acids often contribute to the sour, bitter, and astringent tastes present in plant protein extracts; examples include flavonoids and tannins (see Huang et al., 1991; Roland et al., 2013). The overall reduction in reducing power was from 31% to 61% (from extract to final refined protein isolate). Table 9 below shows that reducing power was quantified using a modified Folin-Ciocalteu assay, reported as mg / L of gallic acid equivalents. The reducing power decreased by 31-86% from extract to refined protein isolate.
[0382] The reducing capacity of each sample was measured using a microplate adaptation of the Folin-Ciocalteu method, adapted from (et al., 2010 "Rapid microplate high-throughput methodology for assessment of Folin-Ciocalteu reducing capacity" Talanta 83; 441-447).
[0383] 1. Extract and purified protein isolate samples were diluted with water to achieve 0.3% protein by weight.
[0384] 2. The sample preparation in the microtiter plate consists of a mixture of the following substances (in this order):
[0385] a.50uL of sample / blank / standard
[0386] b. 50uL of Folin-Ciocalteu reagent 1:5 v / v (or 50uL 0.4M HCl for matrix blank)
[0387] c. 100uL of 0.35NaOH
[0388] 3. Incubate the samples at room temperature for 3 minutes.
[0389] 4. Prepare calibration samples using five gallic acid standards ranging from 5 mg / L to 150 mg / L (prepared daily from 500 mg / L gallic acid stock solution just prior to use).
[0390] 5. The absorbance of the samples was measured at 760 nm in triplicate. The reducing power was expressed as gallic acid equivalent (GAE).
[0391] 6. During assay development, a unit pulse of 50 mg / L GA was added to some samples.
[0392] Table 9.
[0393]
[0394] HPLC analysis was used to quantify the total extractable soluble sugars and organic acids in the original commercial flour isolate and the refined protein isolate to demonstrate the level of purification during the refining process. The samples analyzed on the HPLC were normalized to have the same number of proteins and the supernatant was injected onto an H-column (no acid digestion) after centrifugation. Although we did not identify the individual peaks in the HPLC traces, we compared the total peak areas of the flour and refined protein isolate. These chromatograms show a reduction in the total peak area of the refined protein isolate - the total peak area was reduced by ∼99% in each sample. Fig.13 Shown is the total peak area of the HPLC trace of the extract from the original flour versus the refined protein isolate; only ~1% of the original small molecules remain in the extract after the separation procedure (note the logarithmic scale). The actual chromatogram is shown in Fig.14A -G. Fig.14A The chromatogram is of defatted almond flour diluted to 6.9% protein. Fig. 14B is a chromatogram of a refined protein isolate from defatted almond meal (6.9% protein). Fig. 14C This is a chromatogram of bean flour ground in house and diluted to 3.6% protein.

[0397] GC chromatogram
[0398] We used gas chromatography (GC) analysis to quantify the volatile compounds present in flour and refined PI. Plants contain a wide variety of volatile compounds that may contribute to off-flavors and / or odors, at least to some extent. For five plant sources, protein isolate samples were compared to their original flour sources using gas chromatography. Samples were normalized to have the same amount of protein prior to analysis. The process in this example was able to reduce the total peak area from 88% to nearly 100% from flour to the final product.
[0399] Also tested in this example was the effectiveness of the process when purifying commercial protein isolates. Several commercial isolates (Puris, Roquette) were tested before and after the refining purification process. Figure 15 shows that the total peak area measured in the commercial PI (black bars) was greater than the area in the samples of the PI after the refining process (short dashed bars). The refining process purified protein resulted in the lowest peak area of the sources tested. Table 11 below shows the GC peak areas in the original flour and refined PI samples. The % reduction ranged from 88% to nearly 100%.

[0402] Chickpea flour and yellow pea flour had disproportionately large loading peaks. Most peaks did not appear in the PI. For each source tested, the total area reduction was greater than 88%. Refined protein isolates made from yellow pea and soy were compared to commercial protein isolates. Fig.17A -D shows the GC chromatogram of a commercial protein isolate sample compared with the same plant source after the refining process from flour to protein. Fig.17A The GC chromatogram of a refined protein isolate from yellow peas is shown and this can be compared to three commercial protein isolates (Nutralliance PPI-80 ( Fig. 17B ), Purple Pea 870( Fig. 17C ) and Roquette( Fig.17D Four samples were diluted to 8.6% protein (wt).

[0403] Soy Isoflavones and Tannins
[0404] Isoflavones and tannins are two compounds known to activate bitter receptors. Therefore, this example evaluates the ability of the refined protein separation process to remove tannins and specific bitter isoflavones present in soy flour. The samples were normalized to protein for comparison, and it was clear that the presence of isoflavones detected in soy flour, daidzin, glycitein, and genistin was greatly reduced (95%, 87%, and to below the detection limit, respectively). Tannins, which produce astringent, bitter taste, were reduced by 84.7%. Other plant sources contain different amounts and types of isoflavones, so it is difficult to run this type of test on all eight sources. However, the results with soybeans indicate that the refined separation process is effective in reducing the levels of isoflavones and tannins in the final product. Table 12 shows the concentrations of known soy isoflavones in soy flour, water extracts, and refined protein isolates. The values are normalized to protein % (result % (w / w) / protein % (w / w) x 100). If the values are normalized to % dry mass, then daidzin is 0.014% dry mass, glycitein is below the detection limit, and genistin is 0.048% dry mass. For tannins, the value normalized to % dry mass is 0.18% dry mass.

[0407] Final protein characterization
[0408] Color (L*, a*, b* values)
[0409] One aspect of the refined protein separation process is the removal of color compounds. The production of pure white protein is desirable and can be achieved by using one or more embodiments of the refined protein separation process as disclosed herein.
[0410] The color of refined protein isolates obtained from commercial flour and other protein isolates on the market was measured using the CIELAB color space, where L* represents lightness (0 is black, and 100 is diffuse white), a* is a green / red scale (negative values represent green, positive values represent red), and b* is a blue / yellow scale (negative values represent blue, positive values represent yellow). The sample was prepared as follows: 3% protein (by weight), sunflower oil, sunflower lecithin, guar gum, gellan gum, and tap water. Prior to color analysis, the mixture was homogenized with a multitube mixer and allowed to settle.
[0411] The L* values (related to the brightness of the sample) were higher in the refined protein isolates made from flour (ranging from 76 to 80) (see Table 13) than in the commercial protein isolates (ranging from 66 to 74) (see Table 14). The b values (the higher the b value, the more yellow) were lower in the PIs made from flour.

[0416] Emulsion stability
[0417] To compare changes in protein functionality, emulsion stability of proteins isolated from eight flour sources, as well as commercial whey and rice proteins, was measured (see Table 15). A lower instability index indicates a more stable emulsion. The instability index varied for different sources. Almond protein produced the least stable emulsion among those tested, while emulsions produced with soy protein and phaseol protein were more stable. Yellow pea, chickpea and broad bean had similar stabilities. This suggests that the refined protein isolation process can be used to produce proteins with different functionalities and can be used in end-product development.
[0418] In this example, the method used in measuring the emulsion stability of eight flour sources and whey and rice proteins is shown below. Measurements were made according to the following strategy:
[0419] 1.720 uL of 3.2% protein solution was mixed with 80 uL of sunflower oil and vortexed at speed 9 for 10 min.
[0420] 2. Allow to settle for 5 min. Take 200 uL of the emulsion and mix with 800 uL of SDS 0.1%.
[0421] 3. To measure the instability index in (by LUM GmbH), 350ul of sample was centrifuged at 1500rpm at 20°C for 3min.

[0424] Tasting Panel
[0425] To compare the mouthfeel profiles of refined PI with commercial protein isolates, emulsions were produced with each protein and submitted to a trained taste panel for analysis at Kansas State University. The source of the refined PI in this trial was a commercial PPI that was run through a refining process. Prior to use, the commercial protein was rinsed to achieve the same conductivity of the refined PI in order to remove the high levels of sodium present in most commercial pea protein isolates. Each solution consisted of protein (3.35% by weight), sunflower oil (1.48% by weight), and lecithin and gum to stabilize the emulsion. The emulsion ingredients are shown in Table 16.
[0426] Table 16.
[0427]
[0428] The taste panel evaluated the emulsions for 12 different flavor attributes, assigning the strongest flavor score of 5.0 to the flavor grains and processed. The commercial PPI had stronger "nutty," "woody," and "cereal" flavors (~1.0 point or higher), while the refined PI had a slightly higher score for "beany." The source of the refined PI was the commercial PI to which it was compared, so this trial demonstrated that the refined separation process removed multiple flavor attributes and produced a cleaner tasting product. Fig.18A The differences in taste attributes between emulsions produced with refined PI or rinsed commercial PPI (Roquette S85F) are shown. Fig.18B Individual graphs showing the taste attributes in emulsions produced with refined PI. Fig.18C Separate graphs showing the flavor attributes in emulsions produced with a rinsed commercial PPI (Roquette S85F) are shown. Table 16 shows the flavor attributes in the emulsions produced with a rinsed commercial PPI (Roquette S85F). Fig.18A The largest differences were in the flavor attributes of nutty, beany, woody, and cereal. Fig.19 (Aftertaste comparison between commercial protein and refined protein), Fig. 20 (Texture comparison between commercial and refined proteins) and Fig.21A and Fig. 21B Further evaluation is provided in (Appearance Comparison between Commercial and Refined Proteins).

[0430] 25 batches of refined protein were prepared for use as an ingredient in dairy milk analoques. Manufacturing was performed on a commercial scale as follows:
[0431] 1.600 kg of pea protein isolate (Roquette S85F) was slurried with water to a final solid loading of 12% (by wt%)
[0432] 2. Mix 3.2kg of NaOH into the pea protein and water slurry
[0433] 3. Then mix 46 kg of 34% (by weight) HCl into the pea protein and water slurry
[0434] 4. Then mix 17.8kg of anhydrous CaCl2 into the pea protein and water slurry
[0435] 5. The mixture was recirculated through 3 parallel decanter centrifuges, removing 22 gpm of liquid from the water slurry, and then adding 22 gpm of purified water for 2.5 hours until the bulk conductivity dropped to 2500 uS / cm.
[0436] 6. The slurry is then dewatered using a decanter centrifuge until the final dry solids are between 19-25%.
