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.

soy protein isolate is known to be a good source of nutrition for the body. What are the advantages of soybean protein isolate? What does the future hold for SPI?
l What is soy protein isolate
l What are the benefits of soy protein isolate
l What is the future research direction of soy protein isolate
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.

Soya Beans And Milk
Soy protein is a type of protein which comes from soybean plants.
It comes in 3 different forms – soy flour, concentrates, and soy protein isolates.
The isolates are commonly used in protein powders and health supplements due to their muscle-building qualities.
Soy protein contains essential amino acids which cannot be produced naturally by the body. For this reason, many people on a restricted diet, like vegetarians, consume soy protein supplements for nutritional benefits.
Due to its high volume of amino acids, soy protein is considered to be a “complete protein” by nutritionists, containing similar benefits to the protein found in legume pulses.
It is also one of the cheapest supplemental sources of protein and can be found in foods such as tofu and soy milk.
Soy protein isolate is often used in protein shakes as an alternative to whey, which some people can be sensitive to or avoid consuming for dietary reasons.
What are the types of Soy Protein?
There are two main different types of soy protein – soy protein isolate （Ruiqianjia brand） and soy protein concentrate. Both of these products come from soybean meal, which is then dehulled and defatted before being processed into different parts.
The isolate is a powdered protein supplement which is common in soy protein shakes and supplements. Isolate is 90-95% protein and contains almost no fat or carbohydrates.
Soy protein concentrate, on the other hand, is manufactured by taking the dehulled/defatted soybean meal and removing some of the carbohydrates from it. It is often used in baking, cereals, and as an ingredient for various food products.The concentrate is very easy to digest and contains a lot of fiber, so it is often recommended for children, elderly people, and pregnant women who need to keep a close eye on their health.
Soy Protein Benefits
According to the Food & Drug Administration in the US, soy protein can be used as a good substitute for animal products in a plant-based diet.
2.Fights Heart Problems
Soy reduces LDL cholesterol levels in your body, which is instrumental in fighting heart disease problems.
3.Great for Bone Health
Soy contains phytoestrogen, which makes it easier to absorb calcium. As a result, many soy protein supplements come fortified with calcium, helping to increase your calcium intake. This helps to prevent a loss in bone mass and fights against osteoporosis, a condition where your bones deteriorate as you get older.
4. Increases Energy
Undergoing some intense exercise? Doing some mad workouts at the gym? Soy contains amino acids which can be used by the body and converted into energy. This way, soy protein not only helps you with muscle-building – it also keeps your energy up when you’re working hard to acquire that lean muscle mass!
5. Helps to Prevent Cancer
Soy contains genistein-phytochemicals that have been found to lower risks of prostate cancer and breast cancer, making it attractive to both male and female health nuts alike. The genistein found in soy protein can actually stop tumor cells from growing altogether, halting cancer in its tracks before it can develop and get worse.

With lifestyle changes in recent years, the number of prepared meat products is quietly increasing, ranging from a variety of semi-prepared chicken nuggets, seasoned meat steaks and barbecue products to convenience store staples such as kebab and bento. Through the retail end, prepared meat products are increasingly infiltrating the domestic consumption of the Chinese public, well is gradually becoming a consumer popular. In regulate the development of meat products, soybean protein is a kind of commonly used additives, not only can complement necessary hydrogen acids necessary for human, and mesh has good features such as foaming, emulsification and gel, so it can obviously improve the food's taste, increase elasticity, oily food and water retention, improve the storage performance of food, etc., can reduce the production cost at the same time, In regulate meat processing has the important role
Soybean flour mostly "defatted soybean" trends, because of its protein content is low, so the price is straight, used in meat products, can keep 2 times their own weight of water and flour emulsify material can keep the same weight of cerebral fat class material during hot working out oil, soy meal less functional, There are many shortcomings in taste and flavor, and many restrictions on the range and usage.
Soy Protein Concentrate
Soy Protein Concentrate’s protein content of about 70%, most used in meat products. Soybean concentrated heavy force since the emulsifying gel proportion is protein: water: fat = 1:4:3, It can improve the taste and structure,to improve protein content of meat products.
Isolated Soy Protein
Soy Protein Isolate is a kind of protein produced from low temperature desoluble soybean flour. The protein content is more than 90%, and there are nearly 20 kinds of amino acids, including essential amino acids for human body. It is rich in nutrition and does not contain cholesterol. It is widely used in prepared meat products.
Textured Soy Protein
Textured Soy Protein is made of defatted soya powder, soy protein concentrate or soybean protein isolate as raw materials by mechanical and heat action such as mixing, extrusion and chemical. These proteins have a certain fleshy taste sensation. Therefore, it has special application in meat conditioning and can replace some lean meat raw materials.
1. Water-retaining property
The water retention of soy protein plays an important role in meat production, especially its ability to absorb, combine and bind water in the processing of minced meat products, which can not only retain the juice of raw meat, increase the taste and flavor of products, but also increase the yield of products. The water retention of proteins is also affected by many factors, such as viscosity, pH, ionization strength and temperature. Ma Yuxiang studied the effect of the addition of soy protein isolate on salt-soluble muscle protein heat-induced gel, and the experimental results showed that the addition of soy protein isolate made the ultrastructure of the mixed protein gel rough, reduced the strength of the mixed protein gel, but improved the water-retaining capacity of the gel.
2. Emulsifying property
Emulsifying soybean protein hydrophilic, lipophilic determines its emulsifying stability, soybean protein is a surfactant, it can reduce the surface tension of water and oil, and reduce the surface tension of water and air, so it is easy to form a more stable emulsion. The emulsified oil droplets are stabilized by the heavy white material that accumulates on the surface of the oil droplets, forming a protective layer. This protective layer can prevent the accumulation of oil droplets and the destruction of the emulsification state, so that the emulsification performance is stable. In the preparation of baked food, frozen food and soup food, a large number of studies have been reported on adding human soy protein isolate as emulsifier to stabilize the product state.
3. Caking property
Protein molecular bonding, strong solubility and absorption ability make it has caking property, It apply to adjust food properties. When protein heatto 80 ℃, proteinwill happen business solution or analysis solution, molecular volume increases, viscosity increases, more than 90 ℃ viscosity decreases, pH in six to eight, protein structure is the most stable, maximum viscosity; Above 11, the viscosity is sharply reduced due to the breakdown of protein bonding.
4. Gel property
When meat products containing soy protein are heated, they will form a salty gelatinous structure, which has an obvious effect on the water retention and taste of the products due to the hardness, elasticity, flake and texture of the products. The formation of gel is affected by many factors, including heating time, temperature and concentration of soy protein solution.
Soybean protein contains essential amino acids, which can strengthen the nutritional composition of prepared meat products and play an important role in improving the quality of prepared meat products.
1.High cost effective protein source with enhanced nutrition
Soybean protein has been widely used in the preparation of meat products because of its low price and good protein quality. Adding soybean protein to all kinds of frozen meat products can not only improve the ratio of protein, but also make the nutrition of protein more comprehensive and reasonable.
2.Flavoring in prepared meat products
Soybean protein contains a small amount of fatty acids and carbohydrates, after heating will produce unique aroma, and regulate the products sometimes raw meat (fish) or ingredients and due to the processing of the I art, such as sterilization produced some of the unpleasant smell, may cause consumers antipathy, soy protein unique fragrance smell to above has certain masking effect, Therefore, soy protein has a certain flavoring effect.
3.Soy protein can improve the structure of prepared meat products
Soybean protein has good gel properties and bonding properties, which can effectively improve the texture of the product, enhance the elasticity and hardness of the product, and make the product compact in structure and better in taste. More meaty, especially in fast east meat country, live meatballs and meat products are more sold.
4.The emulsifying property of soybean protein was used to solve the problem of oil coming out of water of prepared meat products
Water, oil is one of the most common problems in the process of cooking in the conditioning of internal products, using the emulsification characteristics of soybean heavy white, so that the water and oil form a grain for the field network structure, so that the water and oil in the conditioning of internal products are very south, in the storage and cooking process of water, oil hidden less.
Two important processes for processing prepared meat products are processing raw meat and curing ingredients. According to the processing characteristics of prepared meat products, there are usually the following adding methods:
Large pieces of fresh meat are added with pickling solution. The soybean protein soluble brine brine is added by injection, and then other processing methods are carried out. This method can make protein evenly distributed in meat. Soy protein generally accounts for 2 to 6 percent of meat products by weight.
That is, soybean protein products in chopping, rolling, stirring process at the beginning of the state of dry material evenly added, but the dry material should be added to the meat products before fat.
In order to make full use of the functional characteristics of soybean protein, soybean protein products had better be hydrated before adding and made into a dispersion containing 18% of protein. The water ratio is soybean powder: water is 1:(1.5~1.8), protein concentrate: water is 1:(2~2.5), protein isolate: water is 1:(3.5~4).
Regulate meat as an emerging industry, its accessories added by the wide attention of the society, as a result of the good function of the soy protein, a variety of features, has become an important conditioning meat processing accessories, the size of the amount of its flavor, texture, structure plays an important role, If add a little amount of product caused not harmonious, not masking bad smell flavor, not to reach the effect of flavouring, And it will lead to loose product structure, soft taste and other adverse results; On the contrary, excessive use of the product will cause too strong bean smell, taste hard and other adverse phenomenons, the specific amount of soy protein to be added according to the quality of soy protein and the type of product to be developed to decide comprehensively.

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.

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.

Why are soy fiber dietary thought to be so good for health? What are the characteristics of soy dietary fiber? What is the function of SPI?
l What is soy dietary fiber?
l What are the soy dietary fiber used for
l What are the health effects of soy dietary fiber
soybean dietary fiberary mainly refers to the general term for macromolecular carbohydrates that cannot be digested by human digestive enzymes, mainly including cellulose, pectin, xylan, mannose, etc. Although dietary fiber cannot provide any nutrients to the human body, it has important physiological functions for the human body. Dietary fiber has the functions of significantly reducing plasma cholesterol, regulating gastrointestinal function and insulin level.
The biological activity of soybean dietary fiberary, regulating blood lipids, lowering cholesterol, soybean dietary fiberary has the ability to bind and exchange cations, and can exchange ca2+, pa2+, etc. During ion exchange, the instantaneous concentration of cations is changed, which plays a role in dilution, so it affects the pH value, osmotic pressure and redox site of the digestive tract, forming an ideal buffer environment. More importantly, it can exchange with NA+ in the intestinal tract, prompting a large amount of K+ and NA+ to be eliminated from the urine and feces, thereby reducing the NA+/K+ value in the blood and directly reducing blood pressure. Therefore, the prevention and treatment of high blood pressure, heart disease and arteriosclerosis is closely related to the excretion of cholesterol and bile acid and dietary fiber. The water-soluble dietary fiber in soybean fiber has the effect of significantly reducing blood cholesterol concentration.
SPI can inhibit and regulate the increase of insulin and blood sugar levels in patients with impaired glucose tolerance. It can promote the absorption of water in the gastrointestinal tract of the human body, delay the absorption of glucose, and at the same time make people feel full, which is beneficial for diabetic and obese patients to eat. It can improve the function of the large intestine.

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.
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.
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%.
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.
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.
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.
