摘　　要：讨论了大枣多糖的脱色最佳条件,正交试验确定双氧水脱色的最佳工艺:双氧水添加量为多糖溶液体积的40%,调节pH8·8,40℃水浴4h,脱色率可达95·4%,多糖的损失率仅为4·8%。AB-8树脂脱色率可达74·48%,多糖损失率为5·6%,两种方法工艺简单,适用于工业化生产。To find out the best condition for the discoloration of polysaccharide from jujube, orthogonal experimental design conform the best condition for the discoloration with H2O02： put 40% H2O2to polysaccharide solution at 40℃ with pH8.8,4h. Polysaccharide losing ratio is 4.8% and discoloration ratio is 95.4%. Using macro-reticular adsorption resin column, the discoloration ratio is 74.48% and polysaccharide losing ratio is 5.6%.
