Process optimization of polyphenol extraction conditions

Use water by enzymatic and response surface methodology to optimize the polyphenol extraction process of rapeseed meal,selected on the basis of single-factor test pH,enzyme dosage,extraction temperature and extraction time to analysis by response surface,then established a quadratic polynomial mathematical model of polyphenol extraction.Finally,through the response surface methodology,the optimum conditions of rapeseed polyphenol extraction as follows: pH value of 4,amount of enzyme of 5.3%,extraction temperature of 56℃,extraction time of 45min,and the polyphenol rate is 10.279mg / g.
