Composition of collagen peptide and elastin peptide, and preparation method and application of composition

The invention relates to the technical field of food and medicines, and discloses a composition of a collagen peptide and an elastin peptide, and a preparation method and application of the composition. The composition of the present invention is composed of a collagen peptide and an elastin peptide, wherein the collagen peptide is produced by enzymolysis of a collagen material by pepsin or trypsin, and the elastin peptide is prepared by enzymolysis of an elastin material via papain and/or a complex protease Protamex. According to the present invention, the elastin peptide and collagen peptidein specific molecular weight ranges are prepared by specific processes, and form the composition at a suitable ratio. The composition can significantly increase the content of elastin and collagen indamaged skin at the same time in a small amount of use, significantly increase the content of hyaluronic acid and hydroxyproline and decrease the content of MMP3, and also can inhibit skin inflammatory factors. 本发明涉及食品和药品技术领域
