Optimization of the Desorption Property of Apple Polyphenols on D280 Macroporous Resin

LI Jian-xi

Abstract

Taking apple polyphenols as test materials,using the response surface method,the effect of optimum desorption technology of apple polyphenols(AP)were researched.The results showed that the optimal desorption process was the ethanol concentration 70%,the elution rate of 0.5mL/min,pH 1.The maximum dynamic desorption rate was 84.58%in theory.The D280 macroporous resin could be used as the better material to extract the apple polyphenols.
