1. Description
Soy extract, also known as soy isoflavones, is typically available in product specifications containing 10%, 20%, and 40% soy isoflavones. Soybean is the seed of leguminous plants. The rich isoflavones in soybean are natural phytoestrogens, which can reduce the incidence of female breast cancer, alleviate menopausal symptoms, and increase bone density
2. Application
The protein isolate made from low-temperature defatted soybean meal through deep processing has a protein content of over 90% and is widely used as a food additive and soybean feed. In industry, soy protein can be used as a raw material for plywood adhesives, pesticide adhesives, fire extinguishers, plastics, and more.
3. Main Efficacy
1. Estrogen like effects: Soy isoflavones are a type of nonsteroidal estrogen with a chemical structure similar to estrogen. They can replace estrogen and bind to estrogen receptors to exert estrogen like effects; It can also interfere with the binding of estrogen and receptor, showing an anti estrogen like effect, having a two-way regulating effect on the level of estrogen in the human body, and has a certain preventive effect on diseases related to estrogen decline such as osteoporosis, atherosclerosis, and elevated blood lipids in women during menopause.
2. Anti tumor effect Soybean isoflavone has obvious anti-tumor effect, especially hormone related tumors, such as breast cancer, prostate cancer, etc. Dye lignin can effectively block the process of vascular proliferation, cut off nutrient sources, thereby delaying or preventing tumor diseases from turning into cancer. At the same time, it can prevent free radicals from damaging deoxyribonucleic acid to reduce cancer. It can also effectively inhibit the occurrence of leukemia, colon cancer, lung cancer, liver cancer, and stomach cancer. Soy saponins in soybean extracts can inhibit tumor growth, have inhibitory effects on DNA synthesis and cell metastasis of tumor cells, directly kill tumor cells, destroy their surface functions, and have a strong inhibitory effect on DNA synthesis in human leukemia cells; At the same time, it has inhibitory effects on the pathogenicity and infectivity of HIV, and has a protective effect against X-rays. Therefore, it has a good resistance to the side effects caused by radiotherapy and chemotherapy in cancer patients, and can also strengthen the body's immunity.
3. Antioxidant effects: Lignin and daidzein are the main active chemical components, and lignin has the strongest antioxidant capacity, both of which can inhibit the formation of lipid peroxides in rat liver microsomes induced by the Fe3+- ADP-NADPH system, with Ic50 values of 1.8 × 10-4M and 6.0 × 10-4M, respectively. At the same time, they also have significant inhibitory effects on the increase of peroxidation levels and the decrease of antioxidant enzyme activity in mice induced by arabinose. Lignin can also increase the production of superoxide dismutase (SOD) in the body.
4. Effect on cardiovascular system Soybean isoflavones have the effects of lowering blood fat and anti atherosclerosis: soybean isoflavones can positively regulate LDL receptors and promote the clearance of cholesterol; The antioxidant properties can reduce the deposition of LDL particles on the coronary artery wall; Dye lignin can reduce basal fiber growth factor and inhibit the proliferation of vascular smooth muscle cells. Soy saponins in soybean extracts can inhibit lipid oxidation in serum, suppress peroxide generation, and reduce cholesterol levels in serum. They have anti lipid oxidation and lipid peroxidation reducing effects, and can also counteract the damage of lipid peroxidation to liver cells. They can also inhibit the reduction of platelets and fibrinogen.
5. Immune effect: Soy isoflavones have the ability to enhance non-specific immune responses.
6. Anti inflammatory effect: Lignin, as a tyrosine kinase inhibitor, can inhibit the formation of NO; It can also inhibit the vascular permeability enhancement induced by vascular endothelial growth factor (VEGF), suppress VEGF expression and release.
