摘要: 采用超滤法分离柑橘皮提取液中的橙皮苷,研究了跨膜压差、温度、流速、体积浓缩比对膜通量的影响和不同清洗剂对膜通量的恢复情况,从而确定了最佳的超滤工艺和膜清洗方法。结果表明:截流分子量为30kD的聚丙烯腈膜在超滤压力为0.25MPa,温度为35℃,进料流速为80L/h,体积浓缩比为3.4时,膜渗透通量相对较高;经结晶后,可得到纯度在85%以上的橙皮苷;先后利用0.1%HCl和0.1%NaOH洗涤超滤膜效果最好。

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.
