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
Meal replacements,breakfast cereals
Energy and protein bars
Weight loss ready-to-drink beverages
snacks

Applications of Soy Fiber
Characters of Soy Dietary Fiber:
-High water binding ability as 1:8 at least;
-Stable characteristics;
-Ability of keeping (supporting) effects of emulsifier;
-Insolubility in water and oil;
-To form gel together with soy protein.
Advantages to Use Soy Dietary Fiber
Thanks to the high water-binding ability, it increases the yield of meat production greatly, for the purpose to reduce the production cost. And the thermal stability of edible fiber under high temperature sterilization also makes it used widely in the production of many kinds of canned food. Besides this, it cleans gall bladder, prevents forming stones and helps to reduce the cholesterol in human blood.
Soy Dietary Fiber is recommended in the following kinds of products:
-Cooked Sausages, Cooked Hams; Half-smoked, boiled-smoked sausages;
-Minced meat;
-Chopped semi-prepared meat;
-Canned food, like Luncheon Meat, Canned Tuna;
-Tomato Mix, Tomato Paste, Tomato Sauce, and other Sauces recommended.

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
1.Meat Substitute
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.

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.
