Black bean peptides are a natural form of protein that is easily absorbed by the body. They are a rich source of essential amino acids such as proline, arginine, and glycine. These amino acids are essential for building muscle mass and promoting healthy skin, nails, and hair. Black bean peptides are also a rich source of bioactive peptides, which play roles in metabolism, cell growth, and maintenance.

Black bean protein molecules are highly compressed and folded, hard and indigestible, except for a small amount of medicinal use, mainly used as feed, and the research on the modification technology of black bean protein resources is relatively late, so that its deep processing and utilization is limited, the black bean protein peptide, which is easy to digest and absorb, is prepared by enzyme-catalyzed hydrolysis of black bean, which overcomes the weakness and deficiency of black bean protein in nutrition, and is the best nutritional way of black bean protein.
