摘要
Abstract
Enzymatic hydrolysis process and its antioxidant activity of the almiond protein were studied. On the basis of single factor, through the Box-Behnken center combination design, enzyme solution conditions were optimized. Results showed that the best hydrolysis con- ditions were pH 14. 72, temperature 54℃, substrate concentration 2. 8% , and enzyme-substrate ratio 1.2%. Under these conditions, the degree of hydrolysis (DH) was 27.12%. The scavenging of almond protein hydrolysates on DPPH . free radical was the strongest, followed by O^[-]2 free radicals, the weakest was the .OH free radical, and clearance rates were 85.92% . 73.97% and 65.92% resDectivlv.关键词
