- . !The soy peptide powder produced by our company is a small molecule oligomer with a relative molecular weight of - which is obtained from non-GMO soy protein isolate through enzymatic hydrolysis with food protease. In addition, peptides also contain a small amount of free amino acids, sugars and other ingredients. The amino acid composition is very similar to soybean protein, and the essential amino acids are well balanced and rich in content.
- . !1. Physical and chemical properties of soybean oligopeptides
- . !． Water solubility:
- . !Soy oligopeptide can be completely dissolved in water and has good solubility. Research shows that the soy oligopeptide aqueous solution produced by our company is still transparent.
- . !． Acid solubility:
- . !Currently, most beverages on the market are weakly acidic, and most proteins are unstable under acidic conditions. This brings difficulties to the development of high-protein drinks. However, soy oligopeptides solve this problem. Because soy oligopeptides have good acid solubility, their solubility is not affected by changes. This provides a basis for the development of acidic protein drinks.
- . !3. Thermal stability
- .! The solubility of soy oligopeptide is not affected by heating. As a protein supplement, it has strong stability, a wide range of applications, and is not prone to precipitation.
- . !． Low viscosity:
- .! Due to its low relative molecular weight, the viscosity of soy oligopeptides does not change much as the concentration increases, and is not greatly affected, that is, the fluidity of soy oligopeptides under acidic or neutral conditions There is no big difference and it is not easy to solidify. This characteristic of soy oligopeptide is suitable for high-protein beverages, and it will not affect the sensory experience even if the added amount reaches 3 or more.
- . ! 2. Physiological activities of soybean oligopeptides
- . !． Small molecular weight, easy to absorb
- . ! Traditional nutrition believes that protein is broken down into amino acids by the human body and then absorbed by the human body. However, a large number of studies in recent years have shown that after protein in food enters the human digestive system, it is decomposed by enzymes secreted by various organs, and is eventually decomposed into peptides with smaller molecular weights and directly absorbed by the human body. Only 3 Be broken down into amino acid forms for absorption. The two work together on the body to become the energy substance of life. Experiments have confirmed that after the soybean oligopeptides produced by our company have been treated with pepsin, the soybean oligopeptides have not been digested. After being treated with trypsin, they have been approximately undigested, indicating that this product has good stability and is mostly in the body. Will be absorbed directly in the form of peptides. At the same time, when this soy oligopeptide product is used to develop functional foods, the physiological functions of the soy peptide itself will not change.
- . !． Promote the absorption and replenishment of electrolytes:
- .! The production and evaporation of sweat during exercise are beneficial to releasing the heat generated by muscle contraction, but it is accompanied by the loss of water and a considerable amount of electrolytes, which disrupts the normal balance of water and electrolytes. to damage, causing a decrease in athletic ability. Soybean oligopeptides can form organic metal complexes with metal ions such as calcium, zinc, copper, magnesium, and iron to protect metal ions and trace elements necessary for the human body, keep trace elements in a good soluble state, and promote the integration of metal ions and Absorption of other trace elements.
- . !3. Anti-exercise fatigue: During people's exercise, protein synthesis is inhibited, while protein utilization is increased, resulting in skeletal muscle damage, reduced exercise ability and exercise fatigue. Therefore, in order to eliminate fatigue and improve exercise ability, quickly and promptly replenishing nitrogen sources after exercise will have a good effect on reducing muscle protein degradation, promoting rapid muscle repair, and eliminating exercise fatigue. Small molecule peptides are the main digestive products of protein and can be used as a quick supplement of the body's nitrogen source due to their easily absorbed properties.
- . !． Improve immunity:
- . !Soy peptides can improve immunity. It can enhance the immune function of macrophages in immune cells and attack viruses that invade the body. Experiments on the immune modulating effect of soybean oligopeptides have confirmed that soybean oligopeptides can significantly promote the immune function of mice, enhance the phagocytic function of macrophages, and promote the activity of killer cells ().
- . !． Antioxidant activity
- . !Antioxidant peptides refer to peptides that are endogenous to organisms or generated by the degradation of biological proteins, and have the ability to inhibit the peroxidation of biological macromolecules or scavenge free radical products in the body. The concentration of soybean oligopeptides when reducing free radicals is..., about / of ascorbic acid.
- . ! In addition, soybean oligopeptides have also been proven to have lower blood pressure, lower blood lipids, reduce the risk of cardiovascular and cerebrovascular diseases, and have anti-tumor activities. Therefore, soy oligopeptides have broad application prospects in the fields of functional beverages, health products, functional foods, especially medical foods.
