摘　　要：研究了离子交换树脂和大孔吸附树脂对大豆低聚糖浆的脱色效果.比较了不同树脂处理大豆低聚糖浆的脱色效果,并选择D392作为脱色树脂,确定的适宜操作条件为：固体分质量分数为10.75%的低聚糖浆与树脂的体积比为11： 1,在常温脱色3～4 h,脱色率可达86%以上,较优解吸剂为w（NaOH）=10%水溶液和无水乙醇的混合溶液V[w（NaOH）＝10%的水溶液]： V（无水乙醇）=1： 1,解吸率达99.81%.The decoloration effect of ion exchange resins and macroporous adsorption resins on soybean oligosaccharide syrup was studied. D392 was chosen as the decolorizing resin by comparing the decoloration effect on the syrup with different resins. The optimal operation parameters within experimental scale were as follows. The solid content of oligosaccharide syrup was 10. 75%. With V （syrup） ： V（resin） = 11 ： 1, decoloring at room temperature for 3～4 h, the decoloration rate was over 86%. The desorption reagent was the mixed solution of equal volumes of NaOH water solution [ w （NaOH） = 10% ] and ethanol[ w（ C2H5OH） = 100% ]. The desorption rate reached 99. 81%.
