1. Prevent obesity and lower blood fat
Soy protein can lower serum cholesterol, and soy peptides have a more obvious effect on lowering serum cholesterol. Soy peptides can hinder the reabsorption of cholesterol in the intestinal tract and promote its excretion from the body. After ingesting soy peptides, soy peptides can promote the activation of sympathetic nerves, induce the activation of brown adipose tissue function, promote the activity of basic metabolism, and promote energy metabolism.
In addition, the intake of soy peptides can hinder the absorption of fat, which can effectively reduce body fat, while keeping the skeletal muscle mass unchanged.
2. Enhance muscle power, accelerate the recovery of myoglobin, and resist fatigue
Endurance exercise strengthens the decomposition of protein, slows down the synthesis speed, and increases the body’s nitrogen excretion; strength exercise also strengthens the decomposition of protein, but at the same time the synthesis of protein in the active muscle group also increases, which is greater than the decomposition rate, so muscles become stronger.
Enhance muscle power and accelerate the recovery of myoglobin. To increase the muscles of athletes, there must be proper exercise stimulation and adequate protein supplementation. Because peptides are easily absorbed and can be used quickly, they inhibit or shorten the process of “negative nitrogen balance” in the body. Especially before and during exercise, peptide supplementation can also slow down the degradation of muscle protein, maintain normal protein synthesis in the body, reduce or delay the changes in other physiological functions caused by exercise, and achieve anti-fatigue effects.
In addition, supplementing soy peptides and soy protein can protect skeletal muscle and cardiomyocytes, which is beneficial to alleviate skeletal muscle micro-injury and myocardial micro-injury after exercise.
3. Promote fat metabolism and energy metabolism
Ingesting protein is easier to promote energy metabolism than eating fat and carbohydrates, and soy peptides have a stronger effect on promoting energy metabolism than protein. During the weight loss of children with obesity, taking a low-energy diet and taking soy peptides as a supplementary food, as a result, can accelerate the reduction of subcutaneous fat more than simply using a low-energy diet.
4. Hypoallergenic antigen performance of soybean peptides
Allergic reaction is an abnormal pathological immune response. Milk protein and soy protein can cause typical allergic reactions. Before food is ingested, the destruction of the molecular size and molecular structure of the allergen is a prerequisite for the reduction and removal of the allergenicity of the product.
Through the degradation of enzymes, the antigenic components in soy protein are greatly reduced. Using enzyme immunoassay (ELISA) for research, the results show that the antigenicity of soybean peptides is lower than that of soybean protein to 0.001-0.010, which has extremely high clinical value.
5. Immunomodulatory function
Soy protein can be obtained by enzymatic hydrolysis or microbial hydrolysis to obtain low molecular weight soy peptides such as Leu-Leu-Tyr and Tyr-Tyr-Met-Pro-Leu-Tyr. As long as a very low dose (0.1μm) can activate the cellular immune function , Enhance human immunity.
6. Antioxidant function
Some scholars use microbial protease to hydrolyze soybean glycinin to obtain peptides with a molecular weight of 700-1400. Tests have shown that it has the effect of inhibiting the auto-oxidation of linoleic acid. In vitro model experiments have proved that these peptides have the effect of scavenging free radicals and can be used for food anti-oxidation. Oxidant and anti-aging food.
7. Promote microbial fermentation
Soy peptides have the effect of promoting the growth and development of microorganisms and active metabolism. The same amino acid or soy protein does not show this effect. Soy peptides can promote the proliferation of lactic acid bacteria, bifidobacteria, yeast and other fungi, and promote the secretion of beneficial metabolites.
8. Improve the bioavailability of minerals
Soy protein contains phytic acid, oxalic acid, fiber, tannin and some other polyphenols, which can inhibit the bioavailability of Zn, Cu, Ca, Mg, etc. in humans or animals. Since soybean peptides are soluble and free low-molecular substances, they can be easily separated and removed from phytic acid, oxalic acid, fiber, tannins and other substances to make soybean protein with low phytic acid content. At the same time, soybean peptides can also interact with Cu, Ca, Mg plasma Chelation forms a soluble complex, which is beneficial to the body’s absorption.
9. Blood pressure lowering effect
Some types of soybean peptides after the hydrolysis of soybean protein can also inhibit the activity of angiotensin-converting enzyme (ACE), prevent the contraction of vascular smooth muscle, and reduce blood pressure. It is worth mentioning that this antihypertensive effect is only for hypertensive patients, and has no antihypertensive effect on normal people.
Some research results show that soy peptides also have the effects of increasing bone density and preventing osteoporosis.
