摘要
研究了 7种阴离子交换树脂对低聚木糖液色素的吸附。结果表明 :7种阴离子交换树脂对低聚木糖液色素的吸附均符合Fre undlich吸附等温方程 ,其中D2 90对低聚木糖液的脱色效果最好 ;D2 90的脱色率为68 8% ,脱色引起的糖分损失率为 1 4 1 %。
Seven types of anion exchange resins were tested to determine the best one in decolorizing of zylo-oligosaccharides syrup.Result showed that the absorption of colorants in xylo-ologosaccharides syrup to these resins accorded with Freundlich absorption equation.In the application conditions(50 ℃,6hours),the strong base anion exchange resin D290 performed best.In Application,68.8% of colorants was removed from the syrups and 14.1% of sugars was lost.
