Description

Grape skins contain active ingredients such as anthocyanins, proanthocyanidins, resveratrol, and polyphenols. Among them, grape skins are richer in resveratrol than grape flesh and grape seeds, which is a polyhydric phenolic compound. In addition to preventing cardiovascular and cerebrovascular diseases, this substance also has strong anti-cancer ability. Widely used in beverages, food, cosmetics, health products or pharmaceutical industries.
