Abstract

Abstract

The preparation and in vivo antioxidant activity of peptides from the protein hydrolysate of oysters were investigated.Fresh Crassostrea angulata were hydrolyzed by a commercial mixture of proteases and spray- dried method to produce oyster peptides. The levels of malondialdehyde( MDA),protein carbonyls( PC) as well as the activities of superoxide dismutase( SOD) and glutathione( GSH) were evaluated for their antioxidant activity of oysters peptides. The results showed that MDA and PC levels in oyster peptides group were significantly decreased( p < 0.01),while SOD and GSH level were significantly increased compared with control group( p <0.01).These results indicated that the antioxidant peptide fractions of spray- dried oyster product exhibited strong antioxidant activity in vivo.
