Hydrolyzed wheat protein is the decomposition of proteins in wheat into smaller fragments by enzymatic hydrolysis or chemical methods, mainly including amino acids and small molecular peptides. Wheat peptide is a kind of plant bioactive peptide derived from wheat protein, containing 15 kinds of essential amino acids. Wheat peptide has the characteristics of good water solubility, easy absorption and strong biological activity. Studies have shown that the protein ingested by the human body is not absorbed in the form of amino acids after the action of enzymes in the digestive system, but more in the form of low peptides. Wheat peptides are widely used in food, health food, industrial manufacturing, cosmetics, feed and so on.
