Abstract：Abstract：It is found recently that the hydrolyzed protein is absorbed not mainly in the form of amino acid, but peptide. Not only can peptide provide nutrition for human growth，but also have physiological active. Pig by-products are rich in collagen, so it is very important in developing collagen peptide products to hydrolyze collagen in enzymatic way. The steps of preparing collagen peptide in enzymatic way are discussed in this paper, as well as the index of enzymatic effect. We look forward to the exploration of collagen peptide.
