What is Hydrolyzed Soy Protein? Uses, Safe and Side Effects


Table of Contents

Hydrolyzed soy protein, or hydrolyzed vegetable protein (HVP), is the result of a process in which high pressure and enzyme action partially breaks down vegetable protein fibers. Instead of the bean-like consistency after cooking, it produces a white dense liquid with 70 to 80 percent protein and 10 to 15 percent carbohydrate content. Hydrolyzed soy protein is chemically defined as: hydrolyzed soy protein = γ-oryzanol + peptides + free amino acids. The following article introduces what is hydrolyzed soy protein, and its uses, safety and side effects and other related contents.

What is hydrolyzed soy protein?

A yellow to brown powder with a salty and umami taste, CAS number 68607-88-5. It is also known as protein hydrolyzates, soya protein or hydrolysed soya protein.


Hydrolyzed Soy Protein is a form of soy protein that has been broken down into smaller pieces. It is often used as an ingredient in foods because it can increase the protein content of the food without adding fat or calories. This can make a product more appealing to consumers looking for healthy options.

Hydrolyzed Soy Protein is made by heating soybeans in water and then treating them with enzymes that break down the proteins. The resulting mixture is filtered, pasteurized and dried into a powder form that can be added to other foods or beverages.

What is hydrolyzed soy protein used for in food?

Hydrolyzed soy protein is a protein extracted from soybeans. It is a white powder that is used in the production of meat substitutes, vegetarian foods, and nutritional supplements.

Soy protein has several health benefits. It can help improve digestive health, reduce cholesterol levels, and improve blood sugar control.

Hydrolyzed soy protein is also known as hydrolyzed soy protein isolate (HSPI) or texturized vegetable protein (TVP). HSPI is a processed form of soy proteins that has been filtered through an acid wash and then treated with heat and enzymes to break down its structure into smaller units that are easier for our bodies to digest.

Why hydrolyzed soy protein has an umami flavor?

Hydrolyzed soy protein has an umami flavor because it contains free glutamic acid. Hydrolyzed proteins are proteins that have been broken down into smaller molecules by hydrolysis. This process creates peptides and free amino acids, which are the building blocks of proteins.

Hydrolyzed soy protein has an umami flavor because it contains free amino acids like glutamic acid, aspartic acid and lysine. These amino acids give hydrolyzed soy protein its unique taste.

What’s interesting about hydrolyzed soy protein is that it’s not only an ingredient with umami flavor but it can also be used to enhance the flavor of other ingredients by providing them with this characteristic savory taste.

How is hydrolyzed soy protein made?

Hydrolyzed soy protein is made by breaking down the protein into smaller molecules by using chemicals or enzymes. The process increases the bioavailability of the protein, making it easier for your body to absorb and use. This makes hydrolyzed soy protein a popular food additive in many processed foods, including energy bars, snacks, cereals and even coffee creamers.

Hydrolyzed soy protein is usually made from soybeans (a legume) or other types of beans such as peanuts or chickpeas. It’s created by heating the beans at high temperatures for a long period of time in an alkaline solution (such as sodium hydroxide). This denatures the proteins in the beans and breaks them down into amino acids or smaller chains of amino acids called peptides. The resulting mixture is then filtered out to remove any solids left behind after processing.

The hydrolyzed proteins can be further refined with additional heat treatments, acid washing or distillation methods to remove salts and sugars before being dried into powder form — which is what you buy at the store.

Does hydrolyzed soy protein contain MSG and how much MSG in hydrolyzed soy protein?

Hydrolyzed soy protein contains glutamic acid naturally and may contain a small amount of MSG (10%-30%).

Difference between hydrolyzed corn and soy protein

The difference between hydrolyzed corn and soy protein is that hydrolyzed corn protein is made from corn, while soy protein is made from soybeans.

The process of making soy protein involves removing the outer layers of the soybean and boiling them to remove their carbohydrates. The remaining product is called concentrate and it’s sold as an ingredient for use in many different food products.

Soy proteins are also used as a meat substitute in vegetarian diets and vegan diets. Soy proteins have been shown to be very effective at lowering cholesterol levels and increasing bone density. Soy proteins have also been proven to reduce cancer risk, improve heart health and help prevent osteoporosis (Bone Loss).

Hydrolyzed corn protein is created by treating corn with water at high temperatures so that its starch breaks down into simple sugars. This process removes all but 5% of the original corn by weight, leaving behind a powdery substance that has an extremely high molecular weight. This makes hydrolyzed corn protein easier for your body to digest than other protein sources like whey or casein because it doesn’t require digestion or stomach acidity for absorption.

What are the uses of hydrolyzed soy protein?

Hydrolyzed soy protein is a protein that has been broken down into smaller molecules. This makes it easier to digest, and also gives it a high bioavailability. It is used in many food products, including health supplements and cosmetics.

Hydrolyzed Soy Protein in Food

The most important use of hydrolyzed soy protein is in the food industry. It is used as an emulsifier, adhesive, thickener and stabilizer in a variety of products such as baked goods, dairy products, ice cream and meat products. Some examples are meats and meat substitutes such as sausages, hot dogs and luncheon meats. In addition to this it also helps maintain the texture and consistency of food items when they are cooked or processed at high temperatures.

Snack Food

Hydrolyzed soy protein is also used in snack foods such as chips, crackers and cookies. The hydrolysis process makes these products crunchy and salty without adding any fat or calories.


Soy sauce and other sauces can be made using hydrolyzed soy protein as an ingredient. Sauces made with hydrolyzed soy protein tend to have a thicker consistency than sauces made with regular soy protein. This makes them good for use on meats, fish, and vegetables.

Canned Food

Hydrolyzed soy protein can also be used in canned foods, such as soups and stews. When added to canned food products, hydrolyzed soy protein helps increase shelf life while maintaining flavor and texture.

Processing Meat

HSP is often used during processing to add texture and improve shelf life by increasing resistance to oxidation and rancidity. It can also be added directly into cooked meat products such as sausages, hot dogs and hamburgers for improved flavor and texture without adding calories or fat.

Convenient Products

Soy is also used in many convenience foods like instant soups and mashed potatoes. The reason for this is that it can be added at a high concentration without changing the taste or smell of the product too much. This makes it possible for companies to add soy protein without having to alter their recipes too much or raise their prices significantly on account of added costs.

Hydrolyzed Soy Protein in Skin Care

Hydrolyzed soy protein has been used in cosmetics since the 1970s. It is used as a conditioning agent in shampoos, conditioners, creams, lotions and other products because of its ability to moisturize skin and hair without leaving an oily residue behind. The hydrolyzed soy protein works by forming an emulsion with water and oil in the skin or hair follicles to form a protective barrier against environmental stressors such as dirt or pollution.

The following products may contain with hydrolyzed soy protein:

  • Bath, Shower & Soaps
  • Shampoos
  • Body care
  • Skin care
  • Hair Conditioners
  • Shaving / Hair Removal

Hydrolyzed Soy Protein in Health Supplements

Health supplements containing hydrolyzed soy protein have been marketed as weight loss aids and muscle builders. However, there is no evidence that hydrolyzed soy protein supplements are effective for these purposes.

Is hydrolyzed soy protein safe to eat?

As a food additive in foods, it is safe for use and has already been approved by the U.S. Food and Drug Administration (FDA) as a safe additive. According to 21CFR170.3, plant protein products are approved by the FDA.

What are the benefits of hydrolyzed soy protein?

Hydrolyzed soy protein is a healthy source of protein and contains all the essential amino acids. It has many health benefits, including:

  1. High in protein. Hydrolyzed soy protein contains more than 75% protein by weight. This means that you can use hydrolyzed soy protein powder to make a shake or smoothie to increase your daily intake of protein.
  2. Low in fat and cholesterol. Each serving of hydrolyzed soy protein powder contains less than 1 gram of fat and no cholesterol.
  3. Gluten-free and lactose-free. Hydrolyzed soy protein is made from soybeans, which are naturally gluten-free and do not contain lactose (a sugar found in milk).

What are the side effects of hydrolyzed soy protein?

Some consumers have questions about whether hydrolyzed soy protein is harmful to our health and what its side effects are. hydrolyzed soy protein side effects include:

Hydrolyzed Soy Protein MSG

MSG (monosodium glutamate) is a flavor enhancer that’s often added to hydrolyzed soy protein products. It can cause headaches, nausea and other symptoms in sensitive individuals.


3-MCPD (3-monochloropropane-1,2-diol) is a byproduct of the manufacturing process that can be found in many foods and food ingredients. It may cause cancer or reproductive damage if consumed in large amounts over many years.

Hydrolyzed Soy Protein Allergy

Some people who are allergic to hydrolyzed soy protein experience mild symptoms such as hives or swelling. In more severe cases, the allergy can trigger anaphylaxis — an extreme reaction that causes difficulty breathing and sometimes death if not treated immediately.

Is hydrolyzed soy protein bad for you?

Soy has been the subject of much controversy over the past few years. While some research has suggested that it may be beneficial to health, other studies have indicated that consuming large amounts of soy could be harmful. One particular concern surrounding soy is its high concentration of phytoestrogens, which can mimic the effects of estrogen in the body and disrupt normal hormone function.

One study found that when rats were given genistein — one of the main phytoestrogens found in soy — for five weeks, they developed breast cancer at a rate more than double that of those who were not given genistein. Another study found that women with breast cancer had significantly higher levels of genistein in their blood than women without breast cancer.

While these studies suggest that genistein may increase your risk of developing cancer, there are no conclusive results regarding whether or not hydrolyzed soy protein causes cancer in humans. It’s also important to note that these studies focused on whole soy products rather than on isolated proteins like hydrolyzed soy protein.

Where to buy hydrolyzed soy protein?

You can find hydrolyzed soy protein at health food stores or online retailers such as Amazon or eBay. If you are looking for an all-natural product with no additives or preservatives then look for brands that contain only the primary ingredient: hydrolyzed soy protein.

Is hydrolyzed soy protein an allergen?

No, hydrolyzed soy protein is not an allergen. It is a common ingredient in many products, including protein bars and energy drinks.

Hydrolyzed soy protein is created by processing soy beans with enzymes to break down large proteins into smaller pieces. This process makes it easier for the body to absorb. Because hydrolyzed soy protein is processed, it is not considered an allergen.

What are the names of HVP in the food label?

To meet FDA’s requirements for specific non-standardized foods, a protein hydrolysate’s common name must be specific to the ingredient and include its source’s identity.

Since the name “hydrolyzed vegetable protein” does not identify the source of the protein, it is not acceptable.

HVP is also known as “hydrolyzed wheat protein,” “hydrolyzed soy protein,” or “hydrolyzed corn protein.”

If I’m sensitive to MSG, should I avoid HVP?

HVP may contain 10-30% MSG, so people who are sensitive to MSG should avoid it. Whenever you’re unsure what food additives are included in a product, look for a food label that contains the word “hydrolyzed.”


Hydrolyzed soy protein is extracted from soybeans with the use of catalyst. It is soluble in water and is separated into two components, namely peptides and amino acids. Peptides are the building blocks of the proteins while amino acid is the main component of hydrolyzed proteins. You can find hydrolyzed protein in cosmetics, personal care products, processed food, and supplements. The major benefit of hydrolyzed protein is that it has a positive effect on your body as it has complete nutrition with enough calories. With all of these benefits, you can see why soy protein is considered as one of the most essential nutrients for your body.
