PEPTIDE HAVING ANTIOXIDANT ACTIVITY FROM CRASSOSTREA GIGAS

摘要

Oyster (Crassostrea gigas) from the in-vitro obtain a peptide through the stomach digestion, purified by FPLC and RP-HPLC it and antioxidant activity, hydroxyl radical (Hydroxyl radical) and superoxide radical in the linoleic acid model system ( superoxide radical) cancellation (scavenging) activity and then the antioxidant activity is the best peptide selected to be an amino acid sequence balhim as antioxidant activity superior relates to a natural antioxidant peptides that can be useful in the development of functional foods Leu-Lys-Gln and measurement -Glu-Leu-Glu-Asp-Leu-Leu-Glu-Lys-Gln-Glu to have a superior effect of providing a material composed of peptides. In addition, the purified peptide of the present invention, gastrointestinal digestion process is mass-produced easily by using a proteolytic enzyme, and using a conventional synthetic antioxidants and natural antioxidants replace high lipid peroxidation inhibitory activity and a free radical scavenging agent than α- tocopherol It has the ability, do not have cell toxicity can harmlessly be used in the human body there are excellent effects that can be widely used in the food processing industry and the field of functional foods. ; Crassostrea gigas, Oyster, antioxidants, peptides
