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.

l Specific application of soybean protein isolate isolate in food
1. Soybean is a magical species. Although it looks simple, it is rich in nutrients. Its protein content is as high as 38%. It has a complete range of amino acids and contains various amino acids necessary for the human body. It is a complete vegetable protein. In terms of nutritional value, it is equivalent to animal protein. Because of these advantages, people all over the world love soy protein isolate products. soy protein isolate has the properties of significantly lowering blood cholesterol. The US FDA has confirmed that long-term consumption of soy protein isolate can reduce the incidence of coronary heart disease, and this is only one aspect.
2. In addition to protein being an important nutrient in food, its functional properties also play a very important and decisive role in the quality of some foods. As a food additive, soy protein isolate can not only supplement the essential amino acids needed by the human body, but also have good functional properties, such as foaming, emulsifying and gelling properties. Elasticity, oil retention and water retention, improve the storage performance of food.
SPI is soybean protein isolate with a protein content of more than 90%. SPI contains a large amount of elements such as C, H, O, N, S, P, and a small amount of trace elements such as Zn, Mg, Fe, and Cu. It is rich in amino acids, including a large amount of glycine, aspartic acid, glutamic acid, lysine and tryptophan, etc., which can provide a variety of amino acids needed by the human body, and is used in meat products, film products, and flour products industries.
SPI can not only be added to meat products as a non-functional additive to replace part of meat products, but also can be used as a functional additive to improve the quality of products, that is, to improve the nutritional content of meat products. Using the water retention and gel properties of soybean protein isolate isolate can improve product texture, improve tissue properties (cut surface, tenderness, taste) and surface morphology, reduce syneresis, and stabilize product yield. The addition of SPI to pasta products can increase the nutritional content of pasta products, improve the elasticity, water absorption and toughness of pasta products, prolong the shelf life of pasta products, and reduce cargo loss. When SPI is used in the production of bread, it can increase the volume of the bread, improve the color of the skin, and have obvious effects on the sensory quality and nutritional value of the bread. The effect is obvious. soybean protein isolate hydrolyzate uses SPI as raw material, and the obtained soybean polypeptide mixture with molecular weight between 180-1000u after hydrolysis has good solubility, reduced beany smell, low allergenicity, more favorable for digestion, and has a selective To promote the proliferation of microorganisms, soybean peptides are added to milk powder because of their promotion of digestion and absorption, low allergenicity, and promotion of the proliferation of probiotics.

The products of vital wheat gluten remained very popular. What is the historical development of vital wheat gluten? What are the functions and uses of wheat gluten?
l What is the development of vital wheat gluten
l What is the advantage of vital wheat gluten
l What is vital wheat gluten used for
The study of cereal protein has a history of 250 years, Beccari first confirmed the existence of wheat protein in 1728. Since then, researchers have never stopped studying wheat protein. Among them, TBOsborne, who is known as the father of plant protein chemistry, has been more influential. He divided wheat proteins into different types according to their solubility in a series of solvents: water soluble. albumin, salt-soluble globulin, alcohol-soluble prolamin, and water- and alcohol-insoluble glutenin.
1. Gluten is a substance obtained after wheat flour is washed with water to remove starch and water-soluble components. In production, it generally refers to water-insoluble protein, which also includes a certain content of lipids (about 10%) and water-insoluble starch. Wheat gluten and bran are often used as feedstuffs as by-products of wheat starch processing.
2. With the in-depth research and the food industry's demand for additives, the value of wheat gluten goes far beyond the wheat starch itself. The research on the deep processing and functional food using gluten as raw material has also attracted more and more attention. Especially after the discovery of wheat protein peptides with various biological activities, such as antioxidant, antihypertensive, and immunity-enhancing activities, the extraction of biologically active small peptides from gluten has become a research hotspot, which is the deep processing of gluten. an important part of research.
wheat gluten flour, also known as active wheat 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%, and it contains fifteen kinds of amino acids necessary for the human body. , is a nutrient-rich vegetable protein resource. It has viscosity, elasticity, extensibility, film forming and liposuction. wheat gluten is an excellent dough improver, widely used in the production of bread, noodles and instant noodles. It can be used as a water-retaining agent in meat products, and it is also the basic raw material of high-grade aquatic feed. At present, gluten is also used as a high-efficiency green flour gluten enhancer in China. It is used in the production of high-wheat gluten flour and special flour for bread, and the amount of addition is not limited. Gluten is also an effective way to increase the content of vegetable protein in food. method.

The company's brand products sell well around more than 20 provinces and cities, and exported to Southeast Asia, South, the Middle East, Norway, Russia and more than 40 countries and regions, product quality excellence, well received by customers at home and abroad. Has been identified by the Shandong provincial government as "Provincial-level key, leading enterprises in agricultural industrialization in Shandong province”, and the top 10 grain and oil industrial park.
The company at this stage vigorously develops wheat, soybean two major circular economy industrial chains.
The group began to develop 300,000 tons of wheat processing industry in 2007. The industry chain is to give priority to extracting high value-added refined flour from wheat. Vital Wheat gluten and superior starch were extracted from secondary flour with lower added value by downstream workshop, (Vital Wheat Gluten is used in high-gluten flour compounding, vegetarian food processing, and superior starch is used in the processing of Vermicelli, cold powder and other products.) The starch pulp composed of residual secondary starch and Pentosan was used to extract food-grade alcohol and medical alcohol through saccharification and fermentation in the production line of alcohol.
On the basis of summarizing the successful experience of wheat industry chain, the company developed 180,000 tons of soybean deep processing industry chain in 2015. Non-GMO soybean oil and food-grade soybean meal were produced from non-GMO soybean. Soybean meal can be used in food processing industry such as 1,000-page Bean Curd, meatball, ham, chafing dish and so on, it can be used in industries such as ketchup and dietary supplement.
The high concentration organic wastewater from the production of wheat and soybean industry chain was transported to the wastewater treatment plant. The remaining high-concentration organic wastewater is converted into biogas by anaerobic fermentation, and the biogas is purified and desulphurized, and then used in power generation or steam supply industry chain. After anaerobic treatment of wastewater by aerobic treatment and then advanced treatment to achieve the recycling water standard as heat and power co-generation boiler make-up water, industrial chain recycling water. The sludge from sewage treatment was fermented at high temperature after dehydration and processed into organic fertilizer, which was used to improve the soil remediation and improve the yield and quality of crops. The wheat and soybean produced by the base are used as raw materials in the industrial chain, thus realizing the development of closed-cycle economy from wheat and soybean planting, intensive processing, sewage treatment to soil improvement and rehabilitation of the planting base.
The 2021 Company actively adapts to the new situation, develops new forms of business, relies on the national rural revitalization industrial policy, takes the industrial prosperity as the lead, encircles the agricultural circular economy chain to extend the strong chain, raises the file to upgrade, an investment of 220 million yuan will be made to build a new project for intensive processing of highly efficient circular agricultural products. The first phase of the project started construction in February of 21, and the trial operation was realized at the end of December. By means of upgrading and building new production line, the project improves the original gluten production line, three new wheat gluten production lines, two wheat starch production lines, sludge and production waste material conversion of organic fertilizer production lines, the project to low value-added secondary flour as raw materials, to build digital, intelligent chemical plants, reduce labor by 40% and energy consumption by 15% , and realize on-line quality real-time monitoring, standardized production, greatly improve product quality, to meet the differentiated and specific needs of different customers, at the same time into the terminal market, the product directly to the dinner table. By upgrading the advanced treatment process of wastewater to further improve the utilization rate of water resources; by reusing sludge and production waste into organic fertilizer back to the field, raw materials are all eaten and squeezed, leaving no waste, finally achieve the whole industry chain of green closed-loop management.

The protein separated from soybean meal. They contain more than 90% protein. The basic principle of producing SPI is simple. Using defatted soybean flakes as raw materials, protein is first dissolved in water. The solution is separated from the solid residue. Finally, the protein is washed out of the solution, separated and dried.
Emulsion:
Isolated soy protein is a kind of surfactant, which can reduce the surface tension of water and oil as well as air. It is easy to form stable emulsion. In the process of making baked food, frozen food and soup food, adding soy protein isolate as emulsifier can make the product stable.
Oil Absorption:
Isolated soy protein can be added into meat products to form emulsion and gel matrix to prevent fat from moving to the surface. Therefore, it can promote fat absorption or fat binding. It can reduce the loss of fat and juice during the processing of meat products, help maintain the stability of appearance, and the oil absorption rate of protein separated is 154%.
Gel:
It has high viscosity, plasticity and elasticity. It can be used not only as a carrier of water, but also as a carrier of flavoring agent, sugar and other complexes, which is very beneficial to food processing.
Foaming property:
In soy protein, the foaming property of protein isolate is the best. The foaming property of soybean protein can give loose structure and good taste to food.
Conjunctival:
When the meat is chopped, the mixture of protein isolate and egg protein is applied on the surface of the fiber to form a thin film, which is easy to dry, can prevent odor loss, is conducive to the rehydration process, and provides a reasonable structure for the rehydrated products.

What is vital wheat gluten
When the heat dough is kneaded and washed in water, part of its starch granules and bran particles are separated from the dough and become suspended, the other part is dissolved in water, and the remaining part is a lumpy rubber-like substance called gluten. Unlike other proteins, wheat gluten is less sensitive to heat and needs to be heated to about 80°C to gel. This shows that most of the molecules in the gluten are S-S cross-links, that is, the gluten protein is composed of a firm tertiary or quaternary structure. Therefore, if the S-S cross-links of gluten are cut with a reducing agent, its thermal sensitivity is significantly improved.
What are the characteristics of hydrolyzed wheat protein
1. Gliadin has ductility, glutenin has elasticity, and can form a network structure with water, so it has excellent viscoelasticity, extensibility, water absorption, liposuction and emulsification, film forming characteristics and light mellow or slightly grainy flavor. and other unique physical properties.
2. The gliadin molecule in wheat protein is spherical, with a relatively small molecular weight (25,000-100,000), with extensibility, but small elasticity; glutenin molecules are fibrous, with a relatively large molecular weight (above 100,000), with elasticity , but the extension is small. The combined action of these two makes wheat protein a unique viscoelasticity that other plant proteins do not have.
What is hydrolyzed wheat protein used for
1. Some of the polypeptides generated by incomplete hydrolysis of wheat protein have certain physiological activities, such as inhibiting hypertension and improving immunity.
2. wheat protein has a wide range of uses in food, and can be used as food preservation agent, emulsifier, foaming agent, chewing gum base, used in wine, edible artificial casing, cheese, acidic beverage, edible thin film, protein film Processing of food, baked goods, breakfast cereals, pet food and meat products.
3. Utilizing wheat gluten enhances dough strength, retains gas and controls expansion for consistent bread volume. The water absorption and retention properties of wheat gluten improve product yield, keep bread soft, extend shelf life, enhance natural taste, etc., and can produce a variety of high-quality bread products.
4. To produce dried noodles, add 1% to 2% active gluten, because the dough is well formed, the softness is increased, and the gluten strength is increased, so the production is convenient and the touch is improved. It is used to produce boiled noodles, which can improve the yield of boiled noodles, prevent noodles from being too soft or broken, and delay the extension of noodles.

P.1: Xinrui Group – Plantation Base – N-GMO Soybean Plants
Soybeans were cultivated in Asia about 3,000 years ago. Soy was first introduced to Europe in the early 18th century and to British colonies in North America in 1765, where it was first grown for hay. Benjamin Franklin wrote a letter in 1770 mentioning bringing soybeans home from England. Soybeans did not become an important crop outside of Asia until about 1910. Soy was introduced to Africa from China in the late 19th Century and is now widespread across the continent.
In America soy was considered an industrial product only and not used as a food prior to the 1920’s. Traditional non-fermented food uses of soybeans include soy milk and from the latter tofu and tofu skin. Fermented foods include soy sauce, fermented bean paste, natto, and tempeh, among others. Originally, soy protein concentrates and isolates were used by the meat industry to bind fat and water in meat applications and to increase protein content in lower grade sausages. They were crudely refined and if added at above 5% amounts, they imparted a “beany” flavor to the finished product. As technology advanced soy products were refined further and exhibit a neutral flavor today.
In the past the soybean industry begged for acceptance but today soybean products can be found in every supermarket. Differently flavored soy milk and roasted soybeans lie next to almonds, walnuts and peanuts. Today soy proteins are considered not just a filler material, but a “good food” and are used by athletes in diet and muscle building drinks or as refreshing fruit smoothies.
P.2: Xinrui Group –N-GMO Soybeans
Soybeans are considered to be a source of complete protein. A complete protein is one that contains significant amounts of all the essential amino acids that must be provided to the human body because of the body’s inability to synthesize them. For this reason soy is a good source of protein amongst many others for vegetarians and vegans or for people who want to reduce the amount of meat they eat. They can replace meat with soy protein products without requiring major adjustments elsewhere in the diet. From the soybean many other products are obtained such as: soy flour, textured vegetable protein, soy oil, soy protein concentrate, soy protein isolate, soy yoghurt, soy milk and animal feed for farm raised fish, poultry and cattle.
The dramatic increase in interest in soy products is largely credited to the 1995 ruling of the Food and Drug Administration allowing health claims for foods containing 6.25 g of protein per serving. The FDA approved soy as an official cholesterol-lowering food along with other heart and health benefits. The FDA granted the following health claim for soy: “25 grams of soy protein a day, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease.”
Soy flour is made by milling soybeans. Depending on the amount of oil extracted the flour can be full-fat or de-fatted. It can be made as fine powder or more coarse soy grits. Protein content of different soy flours:
Full-fat soy flour - 35%.
Low-fat soy flour - 45%.
Defatted soy flour - 47%.
Soy Proteins
Soybeans contain all three of the nutrients required for good nutrition: complete protein, carbohydrate and fat as well as vitamins and minerals including calcium, folic acid and iron. The composition of soy protein is nearly equivalent in quality to meat, milk and egg protein. Soybean oil is 61% polyunsaturated fat and 24% monounsaturated fat which is comparable to the total unsaturated fat content of other vegetable oils. Soybean oil contains no cholesterol.
Commercially processed meats contain soy protein today throughout the world. Soy proteins are used in hot dogs, other sausages, whole muscle foods, salamis, pepperoni pizza toppings, meat patties, vegetarian sausages etc. Hobbyist have also discovered that adding some soy protein allowed them to add more water and improved the texture of the sausage. It eliminated shrivelling and made the sausage plumper.
Soy concentrates and isolates are used in sausages, burgers and other meat products. Soy proteins when mixed with ground meat will form a gel upon heating, entrapping liquid and moisture. They increase firmness and juiciness of the product and reduce cooking loss during frying. In addition they enrich the protein content of many products and make them healthier by reducing the amount of saturated fat and cholesterol that otherwise would be present. Soy protein powders are the most commonly added protein to meat products at around 2-3% as the larger amounts may impart a “beany” flavor to the product. They bind water extremely well and cover fat particles with fine emulsion. This prevents fats from lumping together. The sausage will be juicier, plumper and have less shrivelling.
Soy protein concentrate (about 60% protein), is a natural product that contains around 60% protein and retains most of the soybean’s dietary fiber. SPC can bind 4 parts of water. However, soy concentrates do not form the real gel as they contain some of the insoluble fiber that prevents gel formation; they only form a paste. This does not create a problem as the sausage batter will never be emulsified to the extent that the yoghurt or smoothie drinks are. Before processing, soy protein concentrate is re-hydrated at a ratio of 1:3.
Soy protein isolate, is a natural product that contains at least 90% protein and no other ingredients. It is made from de-fatted soy meal by removing most of the fats and carbohydrates. Therefore, soy protein isolate has a very neutral flavour compared to other soy products. As soy protein isolate is more refined, it costs slightly more than soy protein concentrate. Soy protein isolate can bind 5 parts of water. Soy isolates are excellent emulsifiers of fat and their ability to produce the real gel contributes to the increased firmness of the product. Isolates are added to add juiciness, cohesiveness, and viscosity to a variety of meat, seafood, and poultry products.
P.3: Xinrui Group –Ruiqianjia Brand ISP – Good gel and emulsification.
For making quality sausages the recommended mixing ratio is 1 part of soy protein isolate to 3.3 parts of water. SPI is chosen for delicate products that require superior flavor such as yoghurt, cheese, whole muscle foods and healthy drinks. Isolated Soy protein manufactured by Xinrui Group - Shandong Kawah Oils and exported by Guanxian Ruichang Trading usually contains 90% of protein.
