What Is Soybean Peptide?

Dec 26, 2019

Soybean peptides are a class of active peptides obtained after controlled decomposition of soybean protein, and are usually low molecular weight peptides composed of 3 to 6 amino acids.

Since the 1970s, people have conducted continuous and in-depth research on soybean protein. It has been found that amino acids are well-balanced and rich in content. At the same time, many small molecular weight peptides have not been decomposed when passing through the human digestive tract, which can be directly absorbed and utilized by the human body. Also. it has a variety of physiological activities.

Soybean peptides has good fluidity even at high temperature. So it also has good solubility. The soluble in a wide range of PH value, degree, ionic strength, and nitrogen concentration, especially soy peptide in soy protein The dissolved state is maintained near the isoelectric point PH4.3. The production has become an important direction for the deep processing of soybeans and soy proteins. At the same time, in China, the requirements for peptide nutrition functional foods are becoming stronger and stronger. The production and application prospects are bound to be very broad and the market potential is huge. .

Soy peptides, also known as soy intermediates, refer to oligopeptide peptides obtained after special treatments such as separation and purification of soybean protein after protease action or microbial technology, including some free amino acids, small amounts of sugars, water and Ash and so on.

In the soy peptide powder industry standard stipulated in China, soy peptide powder is defined as "powder soybeans with soybean protein as the main raw material, produced by enzymatic hydrolysis or microbial fermentation, mainly peptides, and having a relative molecular mass distribution below 10000D. The relative molecular mass of the peptide, the length of the peptide chain, and various physical and chemical properties are determined by the enzymes used, the degradation conditions, and the separation method.

With the advancement of biotechnology and the development of life sciences, the physiological functions of active peptides in organisms have been increasingly recognized, especially the clarification of the physiological functions and structures of many active peptides, which has promoted the scientific community's understanding of active peptides. the study.

Endogenous peptides in organisms often play important functions as hormones or nerve mediators. They interact with hormone receptors, signal presentation, and exert regulatory functions (water, minerals and other nutrients), control glandular secretion, regulate blood pressure, and affect body growth. They affect sleep, learning, memory, pain, sexual behavior, appetite, and stress through the role of the central nervous system. Many peptide hormones play an extremely important role in the body's metabolic regulation.
