Soy Protein FAQ
What is defatted soy flour?
Defatted soy flour is divided into roasted and unroasted. Usually used in canned meat, lunch meat, baked goods, etc.
It has certain emulsification (very little) and thickening effect, which can increase the protein content of the product. The protein content is usually ≥52%. If higher protein content products are required, factory customization is required.
Will high temperature affect the structure of soybean protein during enzymatic hydrolysis?
Before the formal enzymatic hydrolysis, our R&D department will repeatedly test the optimal amount of enzyme addition, temperature and time to ensure that the natural properties of soybean protein will not be damaged during enzymatic hydrolysis.
How soy protein is made？
Soy protein products are mainly used as ingredients in formulated foods and seldom are seen by the public. They consist of four broad categories. (1) Most soy proteins are derived from “white flakes,” made by dehulling, flaking, and defatting soybeans by hexane extraction. These may then be milled into defatted flours or grits containing approximately 50-54% protein; extracted with ethanol or acidic waters to remove flavor compounds and flatulence sugars, producing soy protein concentrates containing 65-70% protein; or processed into soy protein isolates containing 90+% protein by alkali extraction of the protein, removal of fiber by centrifugation and reprecipitation and drying of the protein. (2) Full-fat products are made in enzyme-active and in toasted forms. (3) Various dried soyfoods, including soy milk and tofu, are produced. (4) Mixtures of soy proteins with cereals, dried milk or egg fractions, gelatin, stabilizers, and emulsifiers are offered for specific baking, whipping, breading, and batter applications. Texturized products, resembling meat chunks or bacon chips, are made by extrusion of flours and concentrates or spinning of isolates.
How soy protein powder is made?
Once the soybeans have been defatted, they are processed to remove as much of the fats, carbohydrates and fibre as possible to maximise the protein content of the end product. Various techniques could be used with some kind of solvent often utilised to increase the solubility of the powder.
How much soy protein per day is safe?
Based on clinical and epidemiological studies, recommendations for adult intake of soy protein is 15-25 grams per day or 2-4 servings of soy foods per day.
How much soy protein is safe for a man?
Current evidence suggests that excessive intake of soy protein may lead to decreased testosterone/estrogen ratio and attributed side effects in men, with the effect likely mitigated by increasing regularity of physical activity, primarily resistance training. Normal doses of soy protein (20-25g daily), however, are unlikely to lead to any de-masculinizing hormonal changes and may, instead, promote better cardiovascular and prostatic health.
How is soy protein concentrate made?
Soy protein concentrate is about 70% soy protein and is basically defatted soy flour without the water-soluble carbohydrates. It is made by removing part of the carbohydrates (soluble sugars) from dehulled and defatted soybeans. Soy protein concentrate retains most of the fiber of the original soybean.
Choose soy protein or whey protein?
Many people can’t use whey protein. For some, it might be an ethical or dietary choice as they wish to live a vegan or vegetarian lifestyle. For others, it could be an intolerance issue. Lactose intolerance is one of the most common food sensitivities that exists. Whey protein is made from dairy, so if you suffer from lactose intolerance it might not be a good option. Soy protein is dairy free and vegan friendly.
Whey protein is more rapidly absorbed than soy protein.10 However, soy protein is a complete protein with all of the essential amino acids. Because of its slightly slower absorption rates compared to whey protein, it could have the potential benefit of keeping you feeling full for longer.
One benefit of Soy protein over whey protein is that it contains no cholesterol, making it ideal for those who are concerned about their cholesterol levels.
Growth hormone is a hormone inside us that decreases with age. It has many roles in the body which include cellular growth and metabolism. Arginine and lysine are amino acids which are needed help prelease growth hormone.
So, if you’re looking to top your levels up, then soy protein has high amounts of arginine and lysine which could have an acute effect on growth hormone levels.
What are the side effects of soy protein?
Soy has got a lot of bad press over the years. It has been linked to lowering testosterone in men and increasing phytoestrogens. This has only been noted in isolated cases where the intake of soy protein was extremely high and the diet itself was unbalanced.
The majority of the research concludes that the risks of soy as a “feminising” food has been overstated. Soy will have a largely neutral effect on testosterone if combined with a balanced diet.
For most people, soy protein is considered safe with little to no side effects as long as you are not allergic to soy.
What are the health benefits of soy protein?
One of the reasons why people move towards a more plant based diets could to be to eat less dietary cholesterol, as a diet that is high in meats is often high in cholesterol.A benefit of soy protein is that it has no cholesterol and low amounts of saturated fat, whilst being a high quality protein. This makes soy protein a useful alternative to a meat-based equiavalent.
There’s further evidence that soy might actually lower LDL levels (the so-called “bad cholesterol”) and raise HDL levels (good cholesterol). The effects were found to be greater in the less-processed soybeans rather than the refined proteins.
Soy protein is relatively high in zinc, unlike many other plant-based sources. The absorption of zinc from soy is only about 25% lower than that of meat. Low levels of zinc are linked to low testosterone which impacts muscle growth and feeling tired.
So, if you find you’re often feeling drowsy, then maybe try sipping on a soy protein shake.
Soy is also high in vitamin B, calcium, iron, magnesium, phosphorous, and potassium, which are needed to support the immune system and energy production. This can improve that all round feeling of health and wellness and give you that all-important energy boost.
Soy is also high in fibre which helps lower cholesterol, improve gut bacteria, and gut function. A healthy gut means better performance in and out of the gym.
Soy protein can be used as a replacement or an addition to your diet. Since soy protein comes in so many varieties and options there are countless possibilities.
Thinking of taking on a more plant-based lifestyle? Soy protein could be a great option.
Soy protein can also be used as an addition to your regular diet. If you’re looking to increase your protein intake, but can’t use whey or casein, then soy could be a great alternative. It’s high in branch chain amino acids and is a complete protein (contains all 9 essential amino acids), so you won’t have to give up on your muscle-building goals.
Looking to get lean? Soy protein supplementation can fit easily into a calorie deficit diet just as well as a diet designed for muscle gain. Soy is high in an amino acid called leucine, which is responsible for driving muscle growth. This process is essential for both cutting and bulking when you want to maintain and build muscle.
What is soy protein?
Soy protein is a plant-based protein that comes from the soybean, which is a legume. It’s a great source of protein for both vegetarians and vegans alike, as well as those avoiding dairy, with no cholesterol and very little saturated fat.
Soy protein falls into three categories:
This is the highest quality soy protein available. It’s more refined and processed than the others, but it has the highest biological value of all the plant-based proteins. This means the body will use a large amount of what’s ingested.
Soy protein isolate can be found in:
Protein-based supplements (shakes, bars etc.)
Certain meat substitutes
Soy protein concentrate is made by removing the sugars (a part of the soybeans carbohydrate) from de-hulled soybeans. It’s still high in protein, but maintains most of its fibre, which is useful for digestive health.
Soy protein concentrate can be found in:
Infant milk formula
Some meat substitute products
3. Textured soy protein (TSP) or textured vegetable protein (TVP).
This is made from soy protein concentrate, but is found in larger pieces or chunks. It often resembles a meat-based product
Textured soy protein can be used to make many of the popular traditional meat-based meals such as soups, curries, stews and more.
What are the production methods of soy protein concentrate?
Dilute acid precipitation method, alcohol washing precipitation method, wet hot water washing method, acid leaching alcohol precipitation method and membrane separation method. The common feature of these methods is: first, the protein in the soybean meal is precipitated by a certain method (such as heating, adding alcohol), and then the soluble components in the system are separated, so as to achieve the purpose of increasing the protein content. The raw material for the production of soy protein concentrate is generally low-denatured defatted beans.
Why add soy protein to beef？
Adding soy protein to beef can help improve the meat quality and taste of beef. The beef tissue with soy protein is very delicate and elastic, so it can be sliced very well, and it can also ensure the original flavor of beef.
Soy protein is a kind of complete nutrient protein, which can be well absorbed by the human body. Adding soy protein to beef can form a complement with meat protein, making beef more nutritious.
Adding soy protein to beef can emulsify fat, and soy protein has good water holding capacity, which can make beef more tender and more fat. When processing beef products, adding soy protein can make the product structure more perfect.
Why add soy protein to minced meat?
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.
Can soy protein be used in dairy products to increase protein content?
Can. The most commonly used is used in milk powder, milkshakes, and acidic milk products. Any packaged liquid milk will add stabilizers, and the precipitation problem of soy protein can also be solved by adding stabilizers. It should be noted that in the production of dairy products, if it is low-temperature refrigerated milk, there is no problem, but if it is room temperature milk, it will be sterilized during production. The common pasteurization and UHT sterilization are no problems.
How soy protein is used in bakery products?
It is commonly used in cakes, breads and biscuits. It can increase the protein content of the product and produce high-protein products. It can also increase the bulkiness of the cake or bread to make the product soft and taste good. In the production of some bubble candies, there are also cases of using protein. In addition, soy protein is often used in frozen dough in recent years, such as fried dough noodles, hand cakes and other products to add soy protein, which can increase the product’s freezing resistance. In different applications, the requirements for product characteristics are also different.
What are the practical applications of soy protein in the market?
In recent years, there will be some emerging application areas, and there have been practical applications and related products on the market. For example, it can be used in salad dressing, mayonnaise or cheese. Soy protein is also added to pet food, but because animals are more sensitive to beany flavor, they usually require the product to have a light beany flavor.
What are the nutritional value of soy protein?
Drinks made with soy protein are hailed as “green milk” by nutritionists. It protein has a significant lowering effect on people with high cholesterol.
The content of arginine in protein drinks is higher than that in milk, and the ratio of arginine to lysine is also reasonable; the lipid and linoleic acid are extremely rich and contain no cholesterol, which can prevent cardiovascular diseases in adulthood. .
Rich in lecithin, it can remove excess sterols from the blood, and is known as the “vascular scavenger”. Soy protein drinks are easier to digest and absorb than milk.
Milk is easy to form large and hard lumps after entering the stomach, while soy milk is formed into small flakes after entering the stomach, and it is soft and not hard, which can make it easier to digest and absorb.
These soy protein is an essential nutrient for everyone, but the daily dietary intake is largely insufficient, and it must be supplemented by eating protein powder, especially for certain special groups such as children, pregnant women, lactating mothers, and the elderly.
What is the effect of adding soy protein to noodle products?
The lipoxygenase contained in soy protein powder can interact with the carotene in wheat flour to gradually fade the color of carotene, thereby whitening the noodle products. At the same time, the lipoxygenase acts on the hydrogen peroxide produced by fat. It can also oxidize -SH of wheat gluten into -SS-, strengthen the three-dimensional structure of gluten, and enhance the gluten of gluten products.
Soy protein has functional properties such as water retention, gelation, and oil absorption, which can make gluten more delicate and elastic, and improve the processing characteristics and sensory properties of noodle products.
Therefore, adding an appropriate amount of protein to the noodle product not only improves the nutritional value of the noodle product, but also improves its quality to a certain extent.
What is the effect of adding hydrolyzed soy protein in cosmetics?
Hydrolyzed soy protein has a highly effective moisturizing effect and is used as a moisturizer and skin conditioner. Hydrolyzed soy protein helps induce the skin to produce hyaluronic acid, commonly known as hyaluronic acid, which is an ideal natural moisturizing factor, a natural ingredient that promotes skin tissue metabolism and repair functions in women. When the hyaluronic acid content of human skin decreases, it means that the maturation and aging process of the skin is taking place. Hydrolyzed soy protein, in order to induce the role of yuan, increase the concentration of skin hyaluronic acid, in order to achieve a highly effective moisturizing effect.
Amino acids in soy protein
The protein in food is made up of amino acids, and the quality of that protein is based on the number and types of amino acids it contains. Animal foods contain high-quality protein, and egg white has the highest quality protein of all. Unlike other plant or vegetable proteins, soy protein contains all of the essential amino acids necessary for good health. That makes soy protein a complete protein, similar to the protein found in animal foods.
Why are soy protein products hydrolyzed?
After the soybean protein is hydrolyzed, the protein structure will change from long chain to short chain, that is, the protein molecule becomes smaller. Small-molecule proteins are more easily absorbed by the body, so soy protein used in nutritional supplements will be hydrolyzed.
Moreover, the hydrolyzed product is more resistant to high temperature, that is, under high temperature conditions, because small molecules do not like to aggregate, the product has better dispersibility and is not easy to agglomerate.
Does hydrolyzation affect the viscosity of the product?
Hydrolyzation will affect the viscosity of the product to some extent, but it is not the only factor that affects the viscosity. The previous processing technology, the concentration and type of enzymes, and even the raw materials will also affect the viscosity and taste of the product.
How is the hydrolyzation level regulated and controlled in production?
At the time of production, the factory will refer to the use method of enzymes, and adjust and produce according to its own production process. The hydrolyzation level can be controlled by adjusting the enzyme concentration, temperature and time.
During the production process, samples are taken at regular intervals for detection (spotting), real-time monitoring, and the hydrolyzation level is finally reflected by the TCA value.
How to carry out and stop the enzymolysis activity?
The product will be processed in an enzymatic hydrolysis tank, and the production temperature, enzyme concentration and time will be adjusted for enzymatic hydrolysis. After the enzymatic hydrolysis, the product will be transported to the next production link for enzymatic inactivation.
What is the reason for the poor elasticity of sausages produced from emulsion (gel-type) protein isolate?
When emulsion (gel-type) protein isolate are produced as sausages, if they are directly mixed with other raw materials in the poeder form, the produced sausages will have a softer nouthfeel and lower elasticity; if they are first emulsified into solution and then mixed with other raw materials to produce The sausage will have better elasticity.
The elasticity of the sausage will be better if it is emulsified and refrigerated for a while.

It is especially suitable for feed addition for suckling pigs, aquatic products, calves, and pets. Suggested addition: 50-200 kg per ton of feed.
Why use functional soy protein concentrate?
1.The role of protein in meat products includes oil absorption, water retention, bonding, extension, emulsification, gelation, etc., but it is generally believed that emulsification and gelation play a major role in emulsified ground meat products.
The fat particles formed by chopping can contact protein in an instant.
The lipophilic end of the functional protein concentrate FSPC molecular aggregate can be adsorbed on the surface of fat particles, while the hydrophilic end extends into the water phase, which is conducive to the emulsification and stability of solid fat. On the contrary, the spherical soy protein molecules do not have relatively independent hydrophilic and lipophilic ends, and the surface hydrophobicity is low, so they cannot be absorbed in fat immediately.
Fundamentally, the emulsification ability, emulsification stability, salt tolerance and dispersion performance of functional soy protein concentrate are better than soy protein isolate.
2.The content of soy fiber in functional soy protein concentrate is as high as 20%, which is 10 times that of soy protein isolate, and soy fiber can form a matrix system with lean muscle fibers.
It can better maintain the structure of the product, which is very helpful to reduce the shrinkage, water and oil output of meat products.
What should be paid attention to when TVP produces surimi products or crab meat products?
The customer’s protein isolation and protein concentrate products are tested, first of all, the product color, proportion, dispersibility, sedimentation, etc., and secondly, the hardness (gel value), particle size, viscosity, chewiness (palatability), elasticity, etc. will be tested. When introducing the product, you can also cut in from the excellent aspect of the product.
What is Textured Soy Protein?
Textured soybean protein is the conversion of globulin in defatted soybean meal into silk protein and fibrin. Because of its good water absorption and oil retention, when added to meat products, it can increase the color, aroma and taste of meat products and improve protein The content promotes the integrity of the particles, so it is an ideal meat product additive. In addition, the tissue protein has a good granular structure. After soaking, it can be made into vegetarian foods with various flavors. In the process of processing the tissue protein, different flavors can be added, and then added to convenience foods and snack foods. Prepare foods with different flavors.
Uses of Textured Soy Protein
Textured Soy Protein: It can replace pork and beef and is widely used in meat products, fillings, snack foods, etc., adjust the ratio of animal and plant protein, reduce product costs, and improve product quality.
What are the shapes of textured soy protein?
Textured soy protein has different forms, such as granular, block, flake, filamentous, etc., with different shades of yellow-brown, and its network structure is arranged in a directional arrangement to form elastic and tough fiber bundles or layers, so that it has Similar to the bite strength of carnivorous muscle tissue. Typical tissue protein contains about 60% protein.
The difference between soy textured protein and soy silky protein
Although both textured soy protein and silk drawn soybean protein are products produced from soybeans, there is a certain distinction between the two. The following will summarize many years of experience and briefly analyze the difference between soy textured protein and soy silky protein. Soy silk protein is a high-density fibrous plant protein with a texture similar to muscle fiber produced and processed by a variety of plant proteins. It meets international food safety requirements, has high nutritional content, silky structure, soft and chewy taste, and can safely replace all kinds of animal meat. It does not contain fat or cholesterol. It is one of the more popular and safe green and healthy foods.
- Different equipment: the soy protein is produced by a simple single-screw machine (common in China), while the silk-drawn protein is produced by a more complicated twin-screw machine or a three-screw machine (imported equipment is more stable in production);
- Different raw materials: The raw material of soy protein is ordinary edible soybean meal (simple raw material), while the raw material of drawing protein is a mixture of soybean protein isolate, other vegetable protein and edible soybean meal (the raw material requirements are high and complex);
- The organizational structure is different: the structure of soy protein is irregular honeycomb (some manufacturers’ soy protein products have a small amount of filamentous fiber), while the drawn silk protein has a wealth of filamentous fibers;
- Different taste: Textured soybean protein does not have the taste of meat, because it has no filamentous fiber structure, so it is chewed into a crumb state in the mouth, while the drawn silk protein has the same chewing feeling as meat because of its rich fiber filament structure. ；
- The smell is different: the soy protein is limited by the raw materials, and its beany flavor is very strong. Because the beany flavor cannot be masked by other flavors, it is not easy to add too much during use.
Application of soybean tissue protein in meat products
Textured soy protein has good water absorption and oil retention. When added to meat products, it can increase the color, aroma, taste, and protein content of meat products, and can promote the integrity of particles and improve the yield, so it is ideal Meat product additives can be added to meat products to reduce the amount of lean meat added. For example, in the meat sausage, adding the soy protein within 15% of the meat weight can maintain the appearance and quality of the product; in the meatball, adding the soy protein within 20% of the meat weight, the taste and taste are better than pure meatballs ; In the filling of pie and dumplings, adding soy protein within 30% of the meat weight, the quality and flavor are improved, which not only reduces the production cost, but also increases the protein content.
Application of Textured soy protein in Instant Noodles
Textured soy protein has the characteristics of imitating meat structure and can be made into convenience foods with various flavors. Silky and flaky protein products can be directly used to make vegetarian meat-like foods. Block and small particles can be used to make various filling Such foods not only satisfy people’s senses, but also provide high-quality protein sources. It can be eaten after soaking in hot water, and can be used as breakfast and lunch for school-age children.
Application of textured soy protein in leisure food
Textured soy protein has a good granular structure. After processing, it can be processed into various flavors of dried meat, preserves, vegetarian food, etc. During the process of processing tissue protein, different flavors can be added to leisure food. Snack foods with different flavors, rich nutrition and excellent taste can be prepared.
Application of Textured Soy Protein in Nutrition and Health Food
Textured soy protein is not only high in nutritional value, but also an excellent health food, suitable for all ages. It is an auxiliary curative food for patients suffering from cardiovascular disease, arteriosclerosis, diabetes, high blood pressure, high cholesterol, hepatitis, nephritis, and obesity.
Basic use method of soy textured protein
(1) The amount of soy textured protein added in the meat filling accounts for 15%-20% of the meat (wet basis), that is, 15-20kg of tissue protein is added to 100kg of meat. If it is used for vegetarian stuffing, it can be fried with vegetable oil and then mixed with stuffing for better effect according to actual needs.
(2) When adding, take a certain amount of tissue protein (dry basis), soak it in warm water (50℃～70℃) for 20～30rains and remove it, then rinse it with clean water once and dry it before use. After the above treatment, Soak again per kilogram of tissue protein (dry basis) to obtain 2.5-2.9 kg of wet basis. If small particles of tissue protein are used, in order to prevent the loss of small particles with water, wrap the tissue protein with a filter cloth during spin-drying. The tissue protein (wet base) treated above and the meat filling are put into the mixer at the same time, and the seasoning is added , Salt, water and other auxiliary materials can be mixed together.
(3) How to use tissue protein in vegetarian food: directly use tissue protein to make vegetarian food. Use strips or large flakes of tissue protein, soak in warm water (50℃~70℃) for 20~30rains, rinse with water for 1~2 times and spin dry, soak in broth, add salt and different seasonings to stir, It can be made into vegetarian snacks with different tastes.
The characteristics of soy textured protein
(1) The use of soy textured protein can not only increase the protein content of the product, reduce the content of animal fat and cholesterol, prevent the tissue from being damaged by high temperature heating or mechanical action, and lose the touch of the meat, but also reduce the cost of the product. .
(2) The application of soybean tissue protein in meat products is mainly considering their economic and nutritional properties, followed by functionality. Economy mainly refers to the low price of tissue protein products, which can replace part of meat, which can reduce product costs; nutrition refers to the addition of tissue protein to meat products, which can increase the protein content of the product and reduce animal fat and cholesterol The content of soy protein is adapted to modern nutritional needs; functionality refers to the use of soy protein’s emulsification, oil absorption, water absorption, gelation and adhesion to improve the quality of meat products.
(3) Tissue protein is suitable for meat products, simulated nutritious meat, nutritious food and cooking foods of various shapes. When soybean tissue protein is added, it must be rehydrated and deodorized, that is, soak tissue protein 3O in warm water at about 5O℃. ~60min, it can also be soaked in room temperature water, thoroughly rehydrated, rinsed with water for 1 to 2 times, and then shaken dry.
(4) Textured soy protein is not only a substitute for meat in the processing of minced meat products, but also a necessary raw material. In addition, due to its good water absorption and oil absorption, it can reduce processing loss and greasy feeling. Appropriate amount of tissue protein can be added to pie, meat buns, dumplings and other foods to replace part of chicken, beef, etc., without compromising the nutrition and palatability of the food. Some tissue proteins are colored and processed to resemble beef, chicken, ham, and bacon. , Fish and other imitation products have entered the market.
Product Standards of Soy Textured Protein
The product standard of soy textured protein is: protein (dry basis) N×6.25≥50%, fat≤1.5%, crude fiber≤5%, moisture 8%~12%, bulk density≤350g/L, froth rate <5% , The rehydration ratio is 1: (2.5~3), which meets the food hygiene standards. The appearance of this soy protein product is light yellow or yellow-brown, without scorching bitterness, no mildew, and it is sponge-like, lumpy or granular. Similar to lean fibrous tissue, it tastes soft after blister and has fine tissue.
What role does textured soy protein play in minced meat?
Textured soy proteins (TVP) have been used to extend ground meat as a means of reducing the cost without reducing nutritional value. Federal school lunch regulations allow for inclusion of up to 30% TVP in ground meat for that program. Addition of TVP influences the quality of ground meat products, as indicated in several studies. The effect on quality depends on the level of TVP added. Textured soy protein (TSP) products have been used as the extender in most studies although the use of powdered forms also has been explored.
What are the advantages of using textured soy protein in canned food?
1. Textured soy proteins can be fortified with vitamins, minerals, and other supplements to provide balanced nutrition in the final canned product.
2. The extruded products are dried to less than 8% moisture and under normal storage conditions have a shelf-life of about one year. Freezers or cold storage are not required.
3. Textured vegetable proteins maintain their structure upon hydration and provide a meat-like texture.
4. They normally absorb two to three times their weight in water and have good fat-absorption properties.
5. They have low bacteria counts in comparison to meats.
6. The products can be coloured, flavoured, and sized to resemble a wide variety of food products.
7. They allow canners a means of making meat-like canned products in the off-season, thereby allowing year-around utilisation of equipment.
What Does Textured Soy Protein Taste Like?
The beauty of textured soy protein is that it has practically no flavor, meaning you can dress it up to taste however you’d like. It’s commonly used as a mock meat, so it can be seasoned to resemble beef, bacon, chicken, sausage, and more. You can even find some pre-flavored varieties for sale if you’re not interested in seasoning it yourself.
How Do You Cook with Textured Soy Protein?
Since textured soy protein is dehydrated, it needs to be reconstituted in hot water or broth for around 10 minutes before it becomes palatable. For dishes that are already liquidly, like soups or pasta sauces, the dry protein block can simply be stirred in to rehydrate while it simmers.
The way you cook your protein block depends on which shape you purchased. For protein block granules, the texture is similar to ground beef. That makes it ideal for chili, sloppy joes, taco filling, and shepherd’s pie. Larger pieces of protein block, often labeled as “chunks” or “slices,” can be battered and fried to resemble chicken nuggets, thrown into stir-fries, and used to create a meaty stew.
Source of Soy Textured Protein
Soy Textured Protein (TSP) is a concentrated protein product that is generally made from soybeans. It’s a versatile substance that can be used as a meat substitute when seasoning, spices, or herbs are added. It’s especially valuable for people who don’t eat meat, since plant-based foods generally contain less protein than foods from animals. The product can also be used as a meat extender for people who do eat meat.
TVP is sometimes known as textured soy protein or TSP. It’s high in protein and fiber and very low in fat. It’s sold as dried chunks, slices, flakes, granules, or powder and needs to be hydrated before being used. The product has a mild taste on its own but readily absorbs flavor from the liquid in which it’s soaked or cooked. It works well in many foods that traditionally contain ground beef or meat chunks, such as lasagna, chili, veggie burgers, tacos, and “meat” pies.
The difference between wheat protein, vegetable protein and soy protein
Textured vegetable protein, or TVP, is made from soy and is the same thing as textured soy protein. Textured wheat protein is made from a similar process, but from wheat. They are all highly processed plant-based alternatives to meat.
Why is textured soy protein a healthy food?
Short for Textured Soy Protein, TSP is a food product that’s made of defatted soy flour. That means that all oils are removed during processing, which instantly makes it healthier than the real deal. This unique nosh comes in the form of granules, so it looks a lot like ground beef or turkey. No wonder it’s one of the most popular meat substitutes out there. This vegan treat is also jam-packed with dietary fiber and protein, hence the name. While its distinct spongy texture puts off a lot of people at first, TSP taste is unique, often putting many non-vegan bites to shame. Our goal is to show as many people as possible the benefits of TSP including:
- Vegetarian meat substitute or great as a meat extender
- High quality vegetable protein
- Can be used in your kitchen for up to two years or sealed for longer term storage
- Packaged by hand for optimum quality, care and freshness
