Soy oligopeptide products contain all kinds of amino acids, including eight essential amino acids, and their composition ratio is in balance. The results of scientific tests showed that soy oligopeptides could be absorbed more easily than the original soybean proteins or free amino acid compositions, and that it could enter small intestine directly for absorbance without digestion in stomach, and independent from the interference of the body situation. Furthermore, soy oligopeptide products have been demonstrated to consist of many kinds of functional peptides, including antioxidant, antihypertensive, anti-fatigue, immuno- proliferation.
Chinese Center for Disease Control and Prevention (CCDCP) , Chinese Academy of Military Medical Science, Peking University and National Research Institute of Sports Medicine (NRISM) have made research work on the the physiological activities of soy oligopeptides of ZSTH for several years, and identified its health functions, including immunoloregulation effects, anti-fatigue, blood lipid modulation, antihypertensive effect, and modification of the intestinal microflora.

Immunoloregulation effects (finished by Peking University)
· Soy oligopeptides enhanced the cell immunity of delayed type hypersensitivity and ConA-stimulated T lymphocyte proliferation.
· Promoted the phagocytic ability of macrophages.
· Stimulated the killing activity of NK cells.
· According to the procedure of function evaluation of healthy foods by China Ministry of Public Health, the conclusion has been drawed that the soybean oligopeptide powder had immunoloregulation effect.
Antihypertensive effect and blood lipid-lowering effect (finished by Peking University)
· Soy oligopeptides had a potent antihypertensive effect in male & female SHR rats;
· Had no effects on normal blood pressure.
· The soy oligopeptides contained rich antihypertensive peptides (as ACE inhibitors), and is a potent antihypertensive ingredient.
Blood lipid lowering effects (finished by CCDCP)
· Soy oligopeptides could significantly decrease serum Total cholesterol and LDL-C in Wister rats.
· Could significantly increase concentrations of HDL-C in Wister rats.
· According to the procedure of function evaluation of healthy foods by China Ministry of Public Health, the soy oligopeptide powder had blood lipid regulation effects.
With the high quality and fine properties of water solubility, keeping capacity and foaming activity, soy oligopeptides can be completely dissolved at any pH from 2-10, and mixed with other food ingredients without any influence the physical, chemical and nutritional properties.
Therefore soy oligopeptide products are recommended for heath food, infant food, sport food, fermentation food, special diets for clinical nutrition support and the others. They can also be used extensively in laboratory media, fermentation and tissue culture. As a new multi-functional nutritional additive, soy oligopeptides can meet the requirements having wide applications.
