Abstract
Accroding to the properties of static adsorption and desorption of 10 kinds of macroporous absorbent resin for polyphenols in Hanfu apple pomace,the best one was screened to optimize the purified technology of apple polyphenols from Hanfu apple polyphenols. Results indicated that:macroporous resin HPD - 826 had the best properties of adsorption and desorption. The optimal adsorption conditions of apple polyphenols purification were determined as follows:apple polyphenols solution pH 5,solution concentration of apple polyphenols 0. 5 ~ 0. 8mg/mL,feeding speed 1mL/min. And the optimal desorption conditions were ethanol concentration 60%,desorption temperature 20℃,elution speed 0. 5mL/min. Under these conditions,the content of apple polyphenols in purified product was 52. 26%.
