摘要
研究了用ＤＡ１０１、ＤＡ２０１树脂提取赤豆皮色素。实验测得树脂的饱和吸附容量为０．０８８ｇ／ｍｌ湿树脂。选用乙醇－酸作为色素的解析溶剂，确定了乙醇的流速、浓度和用量对色素回收率的影响。
The extraction of red beaus skin colouring agent by macro porous resin was investigated. The absorption capacity of the resin was determined to be 0.088g/ml wet resin colouring/ml wet resin. The ethyl alcohol-acid was used for colouring agent desorption. The effect of flow rate, concentration and volume of ethyl alcohol - acid on desorption of colouring agent were determined too.
