Optimization of the Ultrasonic Wave-Assisted Extraction Condition of Peanut Protein Isolate
Ultrasonic Wave was used to assist alkali extraction and acid precipitation of peanut protein isolate from defatted peanut powder. Based on the single factor test, the response surface analysis results shows that the Ultrasonic Wave-assisted Extraction condition is: ultrasonic power 210W, ultrasonic time 30min, ultrasonic temperature 40°C ,solid to liquid ratio 1:10.7, and under this improved condition the extraction yield could reach 80.09%.
