Zusammenfassung:	The invention relates to a natural antioxidant peptide modifier and application thereof, the modifier comprises DM5-6, DM5-11R and DM5-13R, the amino acid sequence of DM5-6 is phenylalanine-tyrosine-glycine-tyrosine-glutamic acid-cysteine-tryptophan, the molecular weight is 967.15 Da, the amino acid sequence of DM5-11R is phenylalanine-glycine-tyrosine-glutamic acid-cysteine-tryptophan, the amino acid sequence of DM5-11R is phenylalanine-glycine-glycine-glutamic acid-cysteine-tryptophan The amino acid sequence of the DM5-11R is phenylalanine-tyrosine-tyrosine-arginine-cysteine, and the molecular weight of the DM5-11R is 750.93 Da; the amino acid sequence of the DM5-13R is tyrosine-tyrosine-arginine-cysteine, the molecular weight of the DM5-13R is 603.74 Da, and all amino acids of the three modifiers are D-type amino acids. The three modifiers all show antioxidant activity and stability far superior to those of natural maternal peptides, are also very prominent in the aspects of cytotoxicity, hemolysis and the
