| Abstract: | Protein from oyster was hydrolyzed by trypsin.Using single-factor and response surface experiment to analysis the effects of substrate concentration,enzyme concentration,temperature,hydrolysis time,the hydrolyzate indicators is the DPPH radical scavenging rate.The results show that above the optimal level combination of four factors is the solid-liquid ratio 1:3,0.25% of the amount of enzyme,reaction time 2 h,reaction temperature 45 ℃.The hydrolysates exhibited high antioxidative activity. |
