Optimization of preparation process of α-glucosidase inhibitory activity peptide with microwave assisted enzymatic hydrolysis reaction by response surface methodology
摘要
Abstract
In order to optimize the preparation process of α-glucosidase inhibitory activity peptide with microwave assisted enzymatic hydrolysis reaction,cold pressed peanut protein powder was used as raw material,the α-glucosidase inhibitory rate of α-glucosidase inhibitory activity peptide complexes obtained from enzymatic hydrolysis reaction was used as the index.On the basis of single factor experiment,the process was optimized by response surface methodology and Box-Benhnken design.The results showed that the optimum technological conditions were substrate concentration of 9.77%,enzyme dosage of 0.94%,temperature of 59 ℃,time of 10 min,pH value of 9.0,microwave power of 1000 W.The model predictive inhibitory rate under this process condition was 84.80%.And the inhibitory rate of verification experiment was 90.21% ± 0.93%.The difference between the two values was 6.38%.The results provide a theoretical basis for studying the isolation,purification and application of peanut α-glucosidase inhibitory activity peptide.关键词
