摘　　要：研究了离子交换树脂和大孔吸附树脂对菊芋粉除杂液脱色效果的影响,通过单因素试验和正交试验对脱色条件进行优化。结果表明,最佳脱色工艺为采用201×7(717)强碱性阴离子交换树脂,在树脂用量2.5mL/100mL(除杂液),脱色温度45℃,脱色时间40min条件下,菊芋菊粉除杂液的脱色率可达到81.60%,菊粉损失率为5.28%,菊芋中的色素可能主要以阴离子色素、非极性分子色素为主。The single factor test and orthogonal test were carried out to study the effect of different resins （ion-exchange resin and macro-porous absorption resin） on de-color of inulin extract. The results showed that the de-color rate and inulin loss rate of the inulin extract treated by the ion-exchange resin were 81.60% and 5.28% under 2.5mL ion-exchange resin for 100mL inulin extract and 45℃ for 40 min respectively. The pigments of Jerusalem artichoke may be anion pigment and non-polar pigment mainly.
