摘　　要：采用树脂脱色法对低聚果糖粗提取液进行脱色处理,试验结果表明,201×7(717)强碱性阴离子交换树脂对雪莲果低聚果糖提取液中色素的脱除效果最好。最佳脱色条件:上柱流速2mL/min,吸附温度30℃,低聚果糖浓度1.72%。在最佳条件下进行验证试验,脱色率可达90.8%。Crude extraction of fructo-oligosaccharide from yacon was discolored with resin. The results showed that efficiency of discoloration with 201×7 （717） strong alkaline anion exchange resin was the best and the optimum conditions were as follows, the flow rate 2ml/min, adsorption tem- perature 30℃, concentration of fructo-oligosaccharide 1.72%. Discoloration rate reached 90.8% under the optimum conditions.
