Grape by-products mainly consist of grape skins, grape seeds and grape stems, which are rich in polyphenols. (Polyphenols are beneficial to the human body, as described below)
Grape Seed Extract (GSE) is rich in procyanidins, a group of natural pigments with the highest content and purity, which are the main substances for the biological functions of Grape Seed Extract.
Grape Seed Extract are a large group of polyphenolic compounds widely found in plants, and are a member of bioflavonoids, which are a mixture of polyphenols with different degrees of polymerization (DP) formed by the condensation of different amounts of catechins, epicatechin and epicatechin gallate.
Grape Seed Extract Proanthocyanidins are abundant in the roots, stems, leaves, flowers and fruits of many plants, with the highest content in grape seeds. Grape Seed Extract Proanthocyanidins are a mixture of different amounts of monomers polymerized, with oligomeric proanthocyanidins (OPC) being the most widely used in food, cosmetic and nutraceutical applications.
With a potential antioxidant capacity 20 and 50 times higher than that of vitamin E and vitamin C, respectively, proanthocyanidins have very powerful antioxidant and free radical scavenging activities.
Meanwhile, proanthocyanidins have positive effects on atherosclerosis, myocardial ischemia-reperfusion injury, gastrointestinal ulcers, immunosuppression, pathogenic microorganisms, hypertension, diabetes, obesity, etc.
