Description

Grape Seed Extract (CAS 84929-27-1 ) is a concentrated botanical extract derived from the seeds of Vitis vinifera grapes. It delivers a high load of polyphenolic compounds that function as antioxidants and natural preservatives. These compounds, primarily oligomeric proanthocyanidins, act as flavor-modifying agents across food, pharmaceutical, and cosmetic manufacturing. In food and beverage production, it extends shelf life in oils and meat products. By inhibiting oxidative degradation without synthetic additives, it is ideal for functional foods. Nutraceutical and dietary supplement manufacturers incorporate it into capsules, tablets, and softgels targeting antioxidant-positioned products. In personal care formulations, it acts as an oxidative stabilizer in creams, serums, and hair care products. This is particularly useful where lipid rancidity is a primary formulation concern for high-end cosmetic brands. Feed and agricultural applications use this extract as a natural preservative and palatability enhancer in animal nutrition products. It is supplied primarily as a fine powder or spray-dried extract for industrial use. Standardized proanthocyanidin content typically ranges from 95% OPC to lower-standardized food-grade specifications. Food-grade and pharmaceutical-grade designations are the most commercially relevant for global B2B procurement. Some suppliers offer material that is USP -aligned or FCC -compliant to meet strict regulatory requirements. Bulk quantities are available in fiber drums or multi-layer bags suited for large industrial volumes. Contact us for supply of Grape Seed Extract Request Quote
