Raffinose extract solutions contain considerable amounts of colored impurities, and those hydrophobic pigments can be removed by organic solvent extraction. However, there are still water-soluble pigments that can affect the product purity and crystallization processes. In this study, decoloration performance using several resins (HZ-801, HZ-803, HZ-806, HZ-818, D303 and D313) was compared with activated carbon, and the adsorption conditions were optimized according to raffinose decoloration ratio and loss ratio. The results show that HZ-818 is the best candidate with the highest decoloration ratio of 77.1% and loss ratio of 2.4%. The process shows the best cost-effectiveness when the dosage is 2.0 g resin per 10 mL solution under contact time of 9 h. The spent resin can be regenerated with 60% aqueous ethanol and the recycled resins are further used with decoloration ratio up to 94.0%.%棉籽糖的提取液中含有大量的有色杂质，经有机溶剂脱酚处理除去大部分疏水性色素，仍有少量水溶性色素残留，它们的存在会影响棉籽糖产品的纯度、色泽及结晶过程。研究以脱色率和棉籽糖损失率为指标，对比了HZ-801、HZ-803、HZ-806和HZ-818等四种大孔吸附树脂及D313、D303弱碱性阴离子交换树脂与活性炭的脱色性能，考察了影响静态吸附脱色的操作条件及脱色动力学，结果表明：HZ-818树脂为棉籽糖提取液的最佳脱色树脂，单次脱色率最高，达77.1%，棉籽糖损失率2.4%；树脂用量为2.0 g树脂/10 mL溶液、脱色时间为9 h时脱色过程较为经济。吸附色素的树脂可通过60%的乙醇水溶液进行再生，再生后树脂对原料液进行脱色实验，脱色率达94.0%。
