soy oligopeptide products are produced from non-GMO soybean
proteins as raw materials by CSDB using its own serial intellectual property
technologies including biotechnology and bioengineering as the main hi-tech
utilization in the production. Compared with the original soybean proteins used,
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.
1. Immunoloregulation effects (finished by Peking University)
1.1 Soy oligopeptides enhanced the cell immunity of delayed type hypersensitivity and ConA-stimulated T lymphocyte proliferation.
1.2 promoted the phagocytic ability of macrophages.
1.3 stimulated the killing activity of NK cells.
1.4 Conclusion: 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.
2. Antihypertensive effect and blood lipid-lowering effect (finished by Peking University)
2.1 Soy oligopeptides had a potent antihypertensive effect in male & female SHR rats;
2.2 had no effects on normal blood pressure.
2.3 Conclusion: the soy oligopeptides contained rich antihypertensive peptides (as ACE inhibitors), and is a potent antihypertensive ingredient.
3. Blood lipid lowering effects (finished by CCDCP)
3.1 Soy oligopeptides could significantly decrease
serum Total cholesterol and LDL-C in Wister rats.
3.2 Could significantly increase concentrations of HDL-C in Wister rats.
3.3 Conclusion: 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.
The amount recommendation:
Liquid food: milk, yoghurt, fruit beverage, soy milk, sport drink, etc: 0.1-4.0%
Alcoholic beverage: beer, fruit wine, rice wine, spirits: 0.1-0.5%
Solid food: milk powder, protein powder, infant formula, baked food, meat
product, ete: 5.0-20.0 %.
Healthy food: nutritional powder, tablet, capsule, oral liquid, etc: 10-90 %.
