Abstract: In order to promote the development of wrinkles dish bao deep processing industry,the haliotis discus hanai gastropod and Viscera were used as raw material.Peptides Hydrolysate of Gastropods(PHG)and Peptides Hydrolysate of Viscera(PHV)were prepared by protease hydrolysis technology. The contents of heavy metals,main components,in vitro antioxidant activity and bacteriostasis of two kinds of polypeptide hydrolysates were compared and analyzed. The results showed that the contents of heavy metals(As,Hg,Cr,Pb,Cd)in PHG and PHV all met the food safety standard. The content of polypeptides in PHG and PHV were 81.17% and 78.21%,respectively. PHG and PHV had different antioxidant properties,but they had higher antioxidant activity in vitro. The DPPH· scavenging activity of PHG was higher than that of PHV,and its IC₅₀ value was 3.11 mg/mL.The O₂^-· scavenging rate of PHV was higher than that of PHG,and its IC₅₀ value was 4.92 mg/mL. The inhibitory zone diameter of PHG was 8.62 mm greater than that of the positive control 8.06 mm,and the inhibitory zone diameter of PHV was 11.61 mm which was greater than that of the positive control 9.23 mm,which indicated that PHG and PHV had significant inhibitory effects on the growth of Escherichia coli. The above results showed that the enzymatic hydrolysate of abalone platyrhizae and viscera had the guarantee of food safety,high polypeptide content,high antioxidant and bacteriostasis,and it was the high quality raw material for deep processing products such as antioxidant peptides.
