Soy protein powder is a nearly purified protein obtained from soybeans extracted from soybeans through a series of processing steps. soy protein isolate contains eight essential amino acids, which are similar to meat, fish, eggs, and milk, and belong to full-price protein.
After refined processing, soybean protein powder has high nutritional value, but the uses are different. Generally speaking, the molecular weight of soybean protein is relatively large, the digestion process is slightly more complicated, and it is more suitable for ordinary people to supplement nutrition; while the molecular weight of whey protein is relatively small, which is more suitable for the elderly, children and people recovering from illness.
Since the natural soybean protein isolate functional properties are not prominent, it is difficult to meet the different requirements of protein functional properties in food systems. To this end, some methods are needed to improve the functional properties of soybean protein isolate, so that it can be used in a variety of food systems. The modification of SPI is to essentially change the functional properties of soybean protein isolate through physical, chemical, enzymatic or genetic engineering methods, so as to achieve the required quality characteristics of food and expand the application scope of soybean protein isolate in the field of food. The hydrolysate prepared by enzymatic modification of SPI not only has improved functional properties, but also has improved nutritional value. Because of its more obvious advantages, enzymatic modification is considered to be a potential modification method and has become a research hotspot.

What is hydrolyzed wheat protein
1. Wheat contains about 13% protein, mainly composed of albumin, globulin, gliadin and glutenin, while wheat gluten mainly contains gliadin and gluten. Protein, collectively known as storage protein (80% of the dry basis of wheat protein).
2. Due to the ductility of gliadin and the elasticity of glutenin, it can form a network structure with water, so it has excellent viscoelasticity, extensibility, water absorption, liposuction and emulsification, film forming properties, and light and mellow aroma or slightly grainy unique physical properties such as taste.
What is the function of hydrolyzed wheat protein
wheat proteins can be divided into monomeric proteins (consisting of one peptide chain) and aggregated proteins (consisting of two or more peptide chains) according to the number of peptide chains constituting the protein. About 85% of the aggregate protein is glutenin, and the monomeric protein is mainly composed of gliadin, albumin and globulin. Albumin and globulin are mainly deposited in the embryo and aleurone layer, and a small part exists in the endosperm, with a molecular mass of 12-60 kDa, containing more lysine, tryptophan and methionine, which are the most important components in the cell. The enzyme protein is involved in various metabolisms, and the nutritional balance is better, which determines the nutritional quality of wheat.
What are the characteristics of hydrolyzed wheat protein
1. The relative molecular mass of wheat gliadin is 27000-28000. It is a kind of polymer with the highest solubility in 60%-70% ethanol, but insoluble in absolute ethanol. It is slightly soluble in water, can be dissolved in dilute formic acid, propionic acid, benzene, alcohol, p-toluene glacial acetic acid solution, also can be dissolved in weak acid and weak base solution, its isoelectric point is 6.41~7.1. The amino acid composition of wheat gliadin is quite complete, in which the content of glutamic acid is as high as 38.87%, so wheat gluten is often used to prepare MSG.
2. Glutenin is insoluble in water and alcohol, and it is difficult to separate when combined with gliadin. It is slightly soluble in hot ethanol, but after cooling, it becomes flocculent and precipitates. Only newly prepared glutenin that has not been dried is very easy to dissolve. In weak bases and weak acids, and precipitate out during neutralization. Wheat albumin is 0.3% to 0.4% of the mass of the grain, and its isoelectric point is 4.5 to 4.6.

With the deepening of people's understanding of healthy food, Soy Protein Isolate is more and more popular. What are some examples of SPI applications in the food industry? What are the advantages of Soy Protein Isolate?
l What is Soy Protein Isolate?
l Application of Soy Protein Isolate in Meat Products
l Application of Soy Protein Isolate in Baked Food
Soybean protein isolate is a full-value protein food additive produced from low-temperature desolubilized soybean meal.Soy Protein Isolate is an important vegetable protein product, which is rich in nutrients and does not contain cholesterol. One of the varieties of protein, it has been widely used in food and other industries, and its protein content is as high as 90%. The digestibility and utilization rate can reach 93% to 97%. Soybean protein isolate contains 8 kinds of essential amino acids and some amino acids exceed the standard recommended by F A O /WHO. It is mainly composed of 11S and 7S globulin, and the protein composition is essential Eight kinds of amino acids are relatively balanced, especially lysine content is the highest.
At the same time, SPI also contains a lot of essential fatty acids, phospholipids, and minerals such as calcium and phosphorus that are beneficial to human health, and does not contain cholesterol. Its efficacy ratio is higher than that of meat. When mixed with other foods, it can significantly improve the nutritional value of the original food.
1. Minced meat products belong to the general public meat products, and the use of Soy Protein Isolate is small. For minced meat products such as meat patties, minced meatballs, dumplings and steamed buns, they are usually processed by roasting, frying, steaming and boiling. The processing temperature is high. It has good oil absorption properties.
2. Soy Protein Isolate can be used as an additive to improve product texture (reduce free fat). It can not only produce meat-like taste, but also enhance water holding capacity, reduce pie cooking shrinkage, improve yield, and reduce costs. At the same time, it can improve the nutritional value of the product.
When producing bread, adding no more than 5% Soy Protein Isolate can increase the volume of bread, improve the color of the skin, and have obvious effects on the sensory quality and nutritional value of bread (for example, it can make bread products The protein content increases, the volume increases, the texture is soft, the flavor is good, and the nutritional supplementation effect is obvious), and the shelf life of the product can also be extended; but if the amount of Soybean protein isolate added is too large (8%-12%), it will affect The tissue state and sensory quality of the bread will reduce the volume of the bread, thicken the skin, deepen the color, and harden the texture, and the effect is not good. Therefore, when using, the amount of Soybean protein isolate should be paid attention to.

Vital Wheat Gluten is one of the most popular healthy foods. What role does wheat gluten play in the food industry? What are the advantages of organic wheat gluten
l What is organic wheat gluten
l What is the use of organic wheat gluten in food
l What are the health effects of organic wheat gluten
Vital Wheat Gluten has unique properties and is widely used in the food industry and feed industry for the preparation of edible films, bioactive small peptides and other products. Gluten flour, also known as active gluten flour and wheat gluten protein, is a natural protein extracted from wheat (flour). It is composed of a variety of amino acids. The protein content is as high as 75% to 85%. It is a nutrient-rich vegetable protein resource. It has viscosity, elasticity, extensibility, film formability and liposuction. Gluten is an excellent dough improver, which is widely used in the production of bread, noodles and instant noodles. It is used as a water-retaining agent in meat products, and it is also the basic raw material of high-grade aquatic feed.
1. The application of organic wheat gluten in bread flour can significantly improve the water absorption rate of dough, increase dough elasticity, air retention, dough kneading resistance and stability, and significantly improve the internal structure and baking quality of bread. And due to the high protein content of gluten, Maillard reaction often occurs during the baking process, resulting in an attractive aroma, which can improve the quality of bread.
2. organic wheat gluten can also improve the elasticity of foods. For example, after adding gluten to the fish cake, the gluten is restored to a ductile gluten network structure due to water absorption. After kneading, it is evenly mixed with the fish meat. Through heating, the gluten continuously absorbs water and heat denatures, strengthening the fish cake. The elasticity of the sausage; the use of gluten denatured by reducing agents or enzymes in the production of sausage products can enhance the elasticity of sausages.
3. Using wheat gluten as raw material, the edible film prepared has the characteristics of good mechanical properties, edible and degradable properties, and is often used as the substrate of edible film. Studies have shown that the edible film made from gluten has an ideal fresh-keeping effect.
The traditional view holds that protein plays a nutritional role in food, and protein can only be absorbed and utilized by the human body after it is decomposed into free amino acids. However, in recent years, studies have found that after digestion in the human body, proteins are mostly in the form of small peptides composed of 2-7 amino acid molecules, and then directly absorbed by the intestinal tract, and the proportion of amino acids absorbed is very small. At present, the extraction of bioactive small peptides from gluten has become a hot spot in functional food research.

Soy protein isolate is a kind of plant protein with the highest content of protein -90%. It is made from defatted soy meal by removing most of the fats and carbohydrates, yielding a product with 90 percent protein. Therefore, soy protein isolate has a very neutral flavour compared to other soy products. Because most of the carbohydrates are removed, the intake of soy protein isolate does not cause flatulence.
Soy protein isolate, also known as isolated soy protein is used in the food industry for nutritional ( increasing protein content), sensorial ( better mouthfeel, bland flavour) and functional reasons( for applications requiring emulsification, water and fat absorption and adhesive properties).
Soy protein is used in following food products:
Meat processing, frozen products,poultry and fish products
Meat alternatives
Tofu
Baked foods
Soups,sauces and prepared foods

The new generation of veggie burgers aims to replace the beefy original with fake meat or fresher vegetables. To find out how well they do, we ran a blind tasting of six top contenders. By Julia Moskin.
In just two years, food technology has moved consumers from browsing for wan “veggie patties” in the frozen aisle to selecting fresh “plant-based burgers” sold next to the ground beef.
Behind the scenes at the supermarket, giant battles are being waged: Meat producers are suing to have the words “meat” and “burger” restricted to their own products. Makers of meat alternatives like Beyond Meat and Impossible Foods are vying to capture the global fast-food market, as big players like Tyson and Perdue join the fray. Environmental and food scientists are insisting that we eat more plants and less processed food. Many vegetarians and vegans say the goal is to break the habit of eating meat, not feed it with surrogates.
“I would still prefer to eat something that’s not lab-grown,” said Isa Chandra Moskowitz, the chef at the vegan restaurant Modern Love in Omaha, where her own burger is the most popular dish on the menu. “But it’s better for people and for the planet to eat one of those burgers instead of meat every day, if that’s what they are going to do anyway.”
The new refrigerator-case “meat” products already comprise one of the fastest-growing segments of the food industry.
Some are proudly high-tech, assembled from an array of starches, fats, salts, sweeteners and synthetic umami-rich proteins. They are made possible by new technologies that, for example, whip coconut oil and cocoa butter into tiny globules of white fat that give the Beyond Burger the marbled appearance of ground beef.
Others are resolutely simple, based on whole grains and vegetables, and reverse-engineered with ingredients like yeast extract and barley malt to be crustier, browner and juicier than their frozen veggie-burger predecessors. (Some consumers are turning away from those familiar products, not only because of the taste, but because they are most often made with highly processed ingredients.)
But how do all the newcomers perform at the table?
The Times restaurant critic Pete Wells, our cooking columnist Melissa Clark and I lined up both kinds of new vegan burgers for a blind tasting of six national brands. Though many people have already tasted these burgers in restaurants, we wanted to replicate the experience of a home cook. (To that end, Melissa and I roped in our daughters: my 12-year-old vegetarian and her 11-year-old burger aficionado.)
Each burger was seared with a teaspoon of canola oil in a hot skillet, and served in a potato bun. We first tasted them plain, then loaded with our favorites among the classic toppings: ketchup, mustard, mayonnaise, pickles and American cheese. Here are the results, on a rating scale of one to five stars.
1. Impossible Burger
★★★★½
Maker Impossible Foods, Redwood City, Calif.
Slogan “Made From Plants For People Who Love Meat”
Selling points Vegan, gluten-free.
Price $8.99 for a 12-ounce package.
Tasting notes “The most like a beef burger by far,” was my first scribbled note. Everyone liked its crisp edges, and Pete noted its “brawny flavor.” My daughter was convinced it was a real ground beef patty, slipped in to confuse us. The only one of the six contenders that includes genetically modified ingredients, the Impossible Burger contains a compound (soy leghemoglobin) created and manufactured by the company from plant hemoglobins; it quite successfully replicates the “bloody” look and taste of a rare burger. Melissa deemed it “charred in a good way,” but, like most plant-based burgers, it became rather dried out before we finished eating.
Ingredients: Water, soy protein concentrate, coconut oil, sunflower oil, natural flavors, 2 percent or less of: potato protein, methylcellulose, yeast extract, cultured dextrose, food starch-modified, soy leghemoglobin, salt, soy protein isolate, mixed tocopherols (vitamin E), zinc gluconate, thiamine hydrochloride (vitamin B1), sodium ascorbate (vitamin C), niacin, pyridoxine hydrochloride (vitamin B6), riboflavin (vitamin B2), vitamin B12.
2. Beyond Burger
★★★★
Maker Beyond Meat, El Segundo, Calif.
Slogan “Go Beyond”
Selling points Vegan, gluten-free, soy-free, non-G.M.O.
Price $5.99 for two four-ounce patties.
Tasting notes The Beyond Burger was “juicy with a convincing texture,” per Melissa, who also commended its “roundness, with lots of umami.” Her daughter identified a faint but pleasing smoky flavor, reminiscent of barbecue-flavored potato chips. I liked its texture: crumbly but not dry, as a burger should be. This burger was the most visually similar to one made of ground beef, evenly marbled with white fat (made from coconut oil and cocoa butter) and oozing a bit of red juice, from beets. Over all, Pete said, a “real beefy” experience.
Ingredients: Water, pea protein isolate, expeller-pressed canola oil, refined coconut oil, rice protein, natural flavors, cocoa butter, mung bean protein, methylcellulose, potato starch, apple extract, salt, potassium chloride, vinegar, lemon juice concentrate, sunflower lecithin, pomegranate fruit powder, beet juice extract (for color).
3. Lightlife Burger
★★★
Maker Lightlife/Greenleaf Foods, Toronto
Slogan “Food That Shines”
Selling points Vegan, gluten-free, soy-free, non-G.M.O.
Price $5.99 for two four-ounce patties.
Tasting notes “Warm and spicy” with a “crisp exterior” according to Melissa, the Lightlife burger is a new offering from a company that has been making burgers and other meat substitutes from tempeh (a fermented soy product with a sturdier texture than tofu) for decades. That’s probably why it nailed the “firm and chewy texture” that I found a little bready, but “not worse than most fast-food burgers.” “Pretty good when loaded up” was Pete’s final verdict.
Ingredients: Water, pea protein, expeller-pressed canola oil, modified cornstarch, modified cellulose, yeast extract, virgin coconut oil, sea salt, natural flavor, beet powder (for color), ascorbic acid (to promote color retention), onion extract, onion powder, garlic powder.
4. Uncut Burger
★★★
Maker Before the Butcher, San Diego
Slogan “Meaty but Meatless”
Selling points Vegan, gluten-free, non-G.M.O.
Price $5.49 for two four-ounce patties, available later this year.
Tasting notes The Uncut Burger, so named by the manufacturer to imply the opposite of a cut of meat, actually rated among the meatiest of the bunch. I was impressed by its slightly chunky texture, “like good coarse-ground beef,” but Melissa felt it made the burger fall apart “like wet cardboard.” The taste seemed “bacony” to Pete, perhaps because of the “grill flavor” and “smoke flavor” listed in the formula. (To food manufacturers, they are not quite the same thing: one is intended to taste of charring, the other of wood smoke.)
Ingredients: Water, soy protein concentrate, expeller-pressed canola oil, refined coconut oil, isolated soy protein, methylcellulose, yeast extract (yeast extract, salt, natural flavor), caramel color, natural flavor (yeast extract, maltodextrin, salt, natural flavors, medium chain triglycerides, acetic acid, grill flavor [from sunflower oil], smoke flavor), beet juice powder (maltodextrin, beet juice extract, citric acid), natural red color (glycerin, beet juice, annatto), citric acid.
5. FieldBurger
★★½
Maker Field Roast, Seattle
Slogan “Plant-Based Artisanal Meats”
Selling points Vegan, soy-free, non-G.M.O.
Price About $6 for four 3.25-ounce patties.
Tasting notes Not much like meat, but still “much better than the classic” frozen vegetarian patties, to my mind, and the consensus choice for a good vegetable burger (rather than a meat replica). Tasters liked its “vegetal” notes, a reflection of the onions, celery and three different forms of mushroom — fresh, dried and powdered — on the ingredients list. There was some crispness to like in the crust, according to Pete, but the bready interior (it contains gluten) was not popular. “Maybe this burger would do better without a bun?” he asked.
Ingredients: Vital wheat gluten, filtered water, organic expeller-pressed palm fruit oil, barley, garlic, expeller-pressed safflower oil, onions, tomato paste, celery, carrots, naturally flavored yeast extract, onion powder, mushrooms, barley malt, sea salt, spices, carrageenan (Irish moss sea vegetable extract), celery seed, balsamic vinegar, black pepper, shiitake mushrooms, porcini mushroom powder, yellow pea flour.
6. Sweet Earth Fresh Veggie Burger
★★½
Maker Sweet Earth Foods, Moss Landing, Calif.
Slogan “Exotic by Nature, Conscious by Choice”
Selling points Vegan, soy-free, non-G.M.O.
Price About $4.25 for two four-ounce patties.
Tasting notes This burger is sold only in flavors; I chose Mediterranean as the most neutral. Tasters liked the familiar profile of what Melissa declared “the burger for people who love falafel,” made mostly from chickpeas and bulked out with mushrooms and gluten. (Called “vital wheat gluten” on ingredient lists, it is a concentrated formulation of wheat gluten, commonly added to bread to make it lighter and chewier, and the main ingredient in seitan.) The burger wasn’t meaty, but had “nutty, toasted grain” notes that I liked from brown rice, and whiffs of spices like cumin and ginger. This burger is a longtime market leader, and Sweet Earth was recently acquired by Nestlé USA on the strength of it; the company is now introducing a new plant-meat contender called the Awesome Burger.
Ingredients: Garbanzo beans, mushroom, vital wheat gluten, green peas, kale, water, bulgur wheat, barley, bell peppers, carrot, quinoa, extra-virgin olive oil, red onion, celery, flax seed, cilantro, garlic, nutritional yeast, granulated garlic, sea salt, ginger, granulated onion, lime juice concentrate, cumin, canola oil, oregano.
The application scope of soy protein in meat products is becoming more and more extensive, because of its good nutritional value and functional properties.
Adding soy protein in meat products can not only improve the product yield, but also improve the taste of the product. Soy protein has good gel property and water retention. When heated over 60℃, the viscosity increases rapidly, when heated to 80-90℃, the gel structure will be smooth, so that soy protein entering into the tissue of meat can improve the taste and quality of meat greatly. Soybean protein has both hydrophilic and hydrophobic properties which can easily combine with water and saturated with oil, so it has good emulsifying feature. This processing characteristic is very important in the processing of meat products with high fat content, which can restrain the lost of fat to stabilize the product quality. Although soy protein plays an important role in meat processing, in order to control soy protein in meat products replacing of whole meat and prevent adulteration, many countries have restrictly addition of it to ensure the healthy development in meat process. In view of the fact that there is no effective method for the determination of soy protein in meat products, it is great significant to study the detection method of soy protein in meat products.
2 Advantages of applying soy protein in meat products
Meat is reagarded as the best source of protein, owing to its high nutritional value and good taste in western countries. In order to make full use of animal resources, meat processing enterprises not only use protein-rich lean meat, but also often use fat-rich chicken skins, fat and other low-value materials. For example, Bologna sausages, Frankfurt sausages, salami and other meat products have relatively high content of fat. For example, Frankfurt sausages has about 30% of the intestine fat content and raw pork intestine fat content of up to 50%. High fat additions make meat processing more difficult. For example, in the production of emulsified sausages with high fat content, it is easy to form the phenomenon of oil. In order to control the oiling phenomenon of sausages in the heating process, it is necessary to add emulsifiers or accessories with the function of water-preserving oil. Usually, meat products as a "emulsifier" is the meat protein, but once the amount of lean meat added is relatively small, fat content is large, the entire emulsification system will lose balance, some fat in the heating process will be isolated. This can be addressed by adding non-meat protein, thus soy protein the best option. In meat processing, there are several other important reasons for adding soy protein. Medical health experts believe that low-fat meat products are healthier, fatty meat products are more likely to cause high blood pressure and other related diseases. Low-fat meat products will become the future development trend of meat products. Developing low-fat meat products is not simply a reduction in fat addition, which also requires a comprehensive consideration of the taste of product. As fat plays an important role in juicy, tissue structure and other aspects of meat products, once reducing the amount of fat, the taste of meat products will be affected.Therefore, in the development of meat products, "fat substitute" is necessary, it can reduce the fat content of the product on the one hand, on the other hand it can ensure the taste of the product. By adding soy protein, not only can reduce the calories of the product, but also can preserve the flavor and taste of the product to the greatest extent. Wheat protein, egg white and soy protein are better fat substitutes, while soy protein is more popular because of its good processing properties. Another reason to add soy protein is that it's much cheaper than meat protein. Adding plant protein can greatly reduce the production cost of meat products. In the actual production, because of the high price of meat protein, in order to improve the cost performance of the product, the low price of soy protein is often the first choice of production enterprises. In addition, in economically backward areas, animal protein is very scarce, soy protein and other plant protein is the most important source of protein. Soybean protein is the most widely used plant protein. Its main advantages lie in: First, smaller peculiar smell; Second, the price is low; Thirdly, high nutritive value ( soybean protein is rich in essential amino acids, and its digestibility and absorption rate are high in human body ) Fourth, excellent processability (better hydration, gelation and emulsification); Fifth, the use of meat products can improve product appearance quality and palatability. Soy protein can be divided into soy protein concentrate, soy texture protein, soy protein isolate and so on according to their components. Each protein product has different functional properties, which are applied to different types of meat products according to different functional properties. For example, soy protein isolate and protein concentrate are mainly used in some emulsified sausages. Compared with soy protein concentrate, soy protein isolate is rich in raffinose and stachyose oligosaccharides, which can easily cause bloating. Tissue proteins are often used in meatballs and pies. In addition, soy protein isolate ( SPi) and soy protein concentrate ( SPc) are often used in some injection-type meat products to improve the hardness, slicing and yield of the products. Because soybean whole flour has strong beany smell and rough taste, Ruiqianjia soy protein isolate and protein concentrate are better than soy whole flour in food processing.
3 Requirements and problems of soy protein applying in meat products
Too muchh addition of soy protein can cause allergies in some groups of people, in order to prevent soy protein being used as pure whole meat in meat process, to prevent adulteration and ensure the healthy development of the meat industry, many countries have strictly restricted the addition amount of soy protein. Some countries have strictly restricted the amount of soy protein added to meat products. In the United States, for example, the amount of soy flour and soy concentrate protein in sausages can not exceed 3. 5%, the addition of soy protein isolate should not exceed 2%; Soy flour, soy protein concentrate and soy isolated protein in beef patties and meatballs should not be over 12%. In salami, many countries have strict restrictions on the amount of addition soy protein, Spain requires less than 1%; French food laws require less than 2 per cent.
The U.S. labeling requirements for soy protein in meat products are as follows:
When the soy protein addition is less than 1/13, it needs to be identified in the ingredients list; When the addition is close to 10%, it should not only be identified in the ingredients list, but also be commented next to the product name; When its content is more than 10%, soy protein is not only identified in the ingredients list, but also in the product attribute name.
Many countries have strict requirements for the addition of soy protein and the marking of meat products. But there is no effective way to detect soy protein. Because current testing of proteins is mainly determined by detecting nitrogen content, plant proteins and meat proteins are difficult to distinguish. In order to further regulate the use of soy protein in meat products, a method to detect plant protein content is needed. In the 1880s, many food scientists studied the detection of soy protein content in meat products. The enzyme-linked immunoassay method is recognized as a more authoritative test, but the standard of the soy protein added is required to use this method. In view of this, there is no effective way to carry out a simple and rapid test of soy protein in meat products. In order to regulate the use of soy protein in meat products, it is important to develop an effective test
4 Summary
Soy protein as a high-quality plant protein comparable to animal protein, containing the human body's 8 essential amino acids, with high nutritional value, meanwhile soy protein has excellent water & oil bonding and excellent gel characteristics, as well as cheap price and other advantages to make it widely used in meat processing. However, some enterprises use soy protein to increase water retention and thus cover up adulteration, in order to sub-charge, damage consumer rights and interests, which should be severely cracked down and controlled. At present, there is no effective detection method for soy protein in meat products, so it is urgent to develop a new test method for the rapid, convenient and accurate discrimination of meat adulteration.
