摘要:
以灵武长枣废渣提取的红色素为原料，采用8种型号的大孔树脂，以吸附率和解吸率为考察指标，研究纯化红色素的最佳树脂类型及最佳工艺条件。结果表明：LX-60型大孔树脂为色素纯化的最佳吸附树脂；最佳工艺条件为用蒸馏水将色素粗提液稀释25倍（吸光值1.208左右）后，室温下以1.0 mL/min的流速上柱吸附，以50%（体积分数）乙醇作为洗脱剂，室温下以1.0 mL/min的流速进行洗脱；纯化后，枣皮红色素的得率为5.73%，色价为23.61，比纯化前提高了近10倍；该方法适合用于对灵武长枣红色素的纯化。
Abstract:
Taking date-red pigment from Lingwu long jujube as material，using 8 kinds of macroporous resin，and the adsorption rate and desorption rate as testing targets，the best type of resin and best technology were studied.The results showed that the type of LX-60 was the best adsorption resin for purification of pigment，after adding some distilled water to dilute the rough extract of pigment to 25 times (absorbance value of 1.208 or so)，the best experimental conditions were adsorbed on column under the flow rate of the 1.0 mL/min at room temperature;then eluted by with 50% (volume fraction) ethanol under the flow rate of the 1.0 mL/min at room temperature.After purification，the date-red pigment yield was 5.73%;the color value of purified pigment was 10 times higher than that of the beginning to 23.61.This method is suitable for purification of date-red pigment.
