Main types of protein in soybeans

Soybeans are an important source of plant protein and are rich in protein. The proteins in soybeans mainly include the following types.

The first is glycinin.

Globulin is one of the most abundant proteins in soybeans, accounting for about 80% of the total soybean protein. It is a high-quality protein rich in essential amino acids and has high nutritional value. Globulin is commonly used as an emulsifier and stabilizer in food processing to increase the texture and taste of food.

The second is soy protein isolate.

Soy protein isolate is a protein product obtained by extracting and separating soy protein. It is a protein with high purity and contains no other ingredients, so it is widely used in food processing. Soy protein isolate has good solubility and emulsification properties and can be used to make meat products, dairy products, frozen foods, etc.

The third is soybean trypsin inhibitor.

Soybean trypsin inhibitor is a type of anti-nutritional substance in soybeans that can inhibit the activity of trypsin, thereby reducing protein digestion and absorption. Although soy trypsin inhibitor has a certain impact on the human digestive system, moderate intake will not cause obvious adverse effects on health.

The fourth is soybean globulin peptone.

Globulin peptone is a protein product obtained by hydrolyzing glycinin. Globulin peptone has good solubility and bioavailability and can be used as a protein nutritional supplement. Globulin peptone can be quickly absorbed and utilized by the body, providing essential amino acids and energy, helping to promote muscle growth and repair.

The fifth type is soy oligopeptide.

Soy oligopeptides are a type of low molecular peptide obtained from the hydrolysis of soy protein. Soy oligopeptides have certain biological activities and can enhance immunity, resist oxidation, and lower blood pressure. In addition, soy oligopeptides also have good solubility and stability and can be used to make functional foods and health products.

There are many types of proteins in soybeans, each with different characteristics and functions. Reasonable intake of soy protein can provide the essential amino acids needed by the body, increase nutritional intake, and be beneficial to physical health. However, for certain groups of people, such as those who are allergic to soy or have digestive issues, soy protein needs to be consumed with caution. Therefore, when choosing foods, reasonable combination and intake should be based on personal circumstances.
