Optimization of Ultrasonic Assisted Cellulase Extraction Process for Citrus Peel Pectin
The effects of enzyme addition,ultrasonic time and enzymatic hydrolysis time on the extraction effect of pectin were studied by single factor and orthogonal experiments,using ultrasonic-assisted cellulase method to extract pectin from citrus peel,and the pectin extraction rate was used as the investigation index.The results showed that the optimal conditions for the extraction of pectin by ultrasonic-assisted cellulase method were 0.3%cellulase enzyme addition,40 min ultrasonic time and 50 min enzymatic hydrolysis time.The pectin yield under these conditions was 12.6%.
