What is OPC Grape Seed Extract?
OPC Grape Seed Extract is a standardized botanical ingredient from the seeds of the Vitis vinifera grape and is recognized for the naturally occurring oligomeric proanthocyanidins (OPCs) found in these seeds, which are used throughout the world in nutraceutical, functional food, beverage, and personal care applications. Grape seeds are processed with elaborate extraction and purification procedures to produce a fine powder that contains a uniform amount of OPCs that is typically standardized at 95% OPCs or at any other desired specification required for the formulation and manufacturing of the product. It is a polyphenol ingredient derived from plants and is known for its stability, purity, and compatibility with a wide range of product applications. The extract is usually provided in powder form, which is reddish-brown to dark brown, has high dispersibility, and is suitable for capsules, tablets, powder mixtures, sachets, functional drinks, gummies, and cosmetic preparations. The natural polyphenolic content makes it appealing for companies that are looking to develop premium products with botanical ingredients, polyphenol-rich products, or antioxidant formulations. The versatility in formulation, as well as the botanical origin, is appreciated in it. It can be utilized individually or as an ingredient with combinations of other plant extracts, vitamins, minerals, fruit powders, and functional compounds in order to develop differentiated product concepts.
