摘要: 比较6种大孔吸附树脂对红心萝卜花色苷的吸附解吸效果,研究AB-8型大孔树脂对红心萝卜花色苷的吸附与解吸条件。结果表明,AB-8型大孔树脂是纯化红心萝卜花色苷较适合的树脂类型;红心萝卜花色苷在AB-8型树脂上的吸附平衡时间4h,吸附最适温度20℃,花色苷溶液的最适吸附pH3.0,解吸时宜选用75%乙醇溶液。经纯化后的萝卜花色苷为紫黑色粉末,色价为47.8,是纯化前的12倍。

Abstract: The adsorption and desorption effects of 6 kinds of macroporous resins on anthocyanins from red-core radish were compared. The adsorption and desorption properties of resin AB-8 on anthocyanins from red-core radish were further investigated. Results indicated that the adsorption equilibrium time of anthocyanins on resin AB-8 was 4 h. The highest adsorption capacity of resin AB-8 towards anthocyanins from red-core radish was achieved under the conditions of pH 3 and 20 ℃. In addition, 75% ethanol could provide the best desorption effect on anthocyanins from resin AB-8. The purified anthocyanins obtained under the optimal conditions were purple dark powder with color value of 47.8, which exhibited 12-fold enhancement compared with the color value of anthocyanins before purification.
