Black bean peel extract is derived from the seed coat of black beans (Phaseolus vulgaris) through aqueous-ethanol extraction. The peel is exceptionally rich in anthocyanins, particularly delphinidin, petunidin, and malvidin glycosides.
These flavonoid pigments provide strong antioxidant, anti-inflammatory, and cardioprotective benefits. The extract serves as both a functional ingredient and a natural colorant. Commercially, it is used in dietary supplements, natural food coloring, functional foods, and cosmetic formulations.
