Abstract:
Objective To optimize the enzymolysis condition for Acaudina leucoprocta to research lencoprocta the antioxidant activity of its hyoholysate in vivo.Method Response surface methodology (RSM) was employed to optimize the hydrolysis conditions with protamex.The ICR mice were given ig the hydrolysate of Acaudina lencoprocta obtained under optimal conditions.The activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) and the content of MDA in blood serum and liver in mice were analyzed.Results and Conclusion The best hydrolysis conditions were:the amount of enzyme was 2.02%;enzymolysis temperature was 51.18 ℃;enzymolysis time was 127.81min,hydroxyl radical scavenging rate was 73.10%.The activities of SOD,GSH-Px in hydrolysate were significantly enhanced and the content of MDA was significantly lower,which showed that this hydrolysate had remarkable antioxidation activity.So the enzymolysis technology for Acaudina leucoprocta was optimal.
