Abstract
Based on single factor experiment,the amount of complex enzymes,the optimum ultrasonic pre-irradiation temperature,time,enzyme hydrolysis pH,enzyme hydrolysis temperature and reaction time were chosen as influencing factors and the peanut protein yield was selected as response value.The optimum extraction conditions were as follows:amount of complex enzymes 1.59%,enzyme hydrolysis temperature 56.5℃,reaction time 3.9h,the ratio of material to liquid 1∶ 4.4 and enzyme hydrolysis pH 9.0.The peanut protein yield was 94.31%±0.37%.
