Abstract:
【Abstract】 Hesperidin derived from citrus peel extraction was separated by ultrafiltration (UF) technology. The effects of transmembrane pressure (TMP), axial flow-rate, temperature, the volume concentration rate (VCR) of hesperidin extraction on ultrafiltration permeates flux and different cleaning agents on the recovery of membrane flux were investigated. The results showed that the optimum conditions are:the ultrafiltration membrane with 30000 molecule weight cutoff (MWCO) runing at TMP 0.25 MPa, temperature 30 ℃, axial flow-rate 80 L/h and VCR 3.4;the hesperidin with over 85% purity can be obtained after crystallization;the cleaning efficiency is best with 0.1% HCl and 0.1% NaOH.
