| 摘 要： | 比较了5种大孔吸附树脂对"黑美人"土豆色素的吸附和解吸效果,研究了AB-8树脂对"黑美人"土豆色素的静态吸附和解吸性能。结果表明,"黑美人"土豆色素在AB-8树脂上吸附平衡时间为8h,解吸平衡时间为2h,在吸附液pH3.0、温度为40℃时吸附能力最强;以pH3.0的90%的乙醇为洗脱液解吸效果较好。经AB-8大孔吸附树脂纯化后的色素色价比粗品提高了8.4倍。实验结果表明,AB-8树脂可用于"黑美人"土豆色素的分离与纯化。

| Abstract: | The absorption and desorption effects of 5 kinds of macroporous absorption resins on pigment from "Black Beauty"potato were compared,and the properties of static adsorption and desorption for AB-8 on "Black Beauty" potato pigment were further investigated.The results showed that the time of absorption and desorption equilibrium were 8h and 2h.Under the conditions of pH 3.0 and 40℃,the highest adsorpion ability for "Black Beauty" potato pigment was achieved,and elution the effect was better by using 90% ethanol solution at pH 3.0,which resulted in a 8.4-fold increase of color value.The results indicated that AB-8 resin could be used for separating and purifying for pigment from"Black Beauty" potato. |
