Beschreibung
Zusammenfassung:	The invention belongs to the technical field of polypeptiomics and molecular biology, and particularly provides an antioxidant polypeptide screening method based on combination of a polypeptiomics technology and a bioinformatics prediction technology and application of the antioxidant polypeptide screening method. According to the present invention, the polypeptide on the body wall of the sea cucumber is detected by using the polypeptiomics test method, the antioxidant activity of the obtained multiple polypeptide sequences is predicted by using the bioinformatics method, one polypeptide having potential antioxidant activity is selected to perform chemical synthesis, and then the antioxidant activity is detected by using a variety of antioxidant activity detection methods; according to the method, the sample activity detection efficiency is higher, and the screening efficiency of the antioxidative peptide can be greatly improved, so that the sea cucumber antioxidative peptide SC-13 has a good practical applic
