What is Bulk Resveratrol Powder?
Bulk Resveratrol Powder is a plant-based, high-purity extract used as a functional ingredient in the nutraceutical, food, cosmetic, and pharmaceutical manufacturing sectors. It is a naturally occurring polyphenolic compound chemically referred to as 3, 5, 4'- trihydroxystilbene that is mainly found in Polygonum cuspidatum (Japanese Knotweed), red grapes, berries, and peanuts. In industries, it is normally recovered and purified with the aid of sophisticated solvent extraction and purification methods to give specifications of 50-99 percent purity (by HPLC), according to the end-use requirements. It is a major raw material to create dietary supplements, anti-aging products, cosmetics, functional drinks, and other health-promoting products. Manufacturers use the bulk powder form due to its stability, versatility, and ease of formulation. The off-white to light beige fine powder is highly soluble in ethanol and other organic solvents, which means that it will be compatible with water-based and oil-based systems. It has an inert smell and a light taste that makes it appropriate to be mixed in different product matrices without compromise of flavor or sensory quality.
