摘要
为了筛选出一种高吸附、高解吸性能大孔吸附树脂,比较了14种大孔吸附树脂对紫甘薯色素的静态吸附和解吸性能。在此基础上研究了吸附液pH、解吸流速、洗脱液浓度及pH对色素纯化的影响。结果表明：DM21树脂为分离纯化紫甘薯色素的最佳树脂,其最佳纯化条件是吸附液和解吸液pH2.0~4.0,解吸液乙醇浓度为70%,解吸液解析流速为3Bv·h-1时,对紫甘薯色素的纯化效果以及效率最好,色价达到54.26±0.87。
The performances of pigments fromIpomoea batatas（L.）Lam extracts on fourteen macroporous resins were investigated in order to optimize the separation process,different pH values of sample solution,different desorption velocities,different concentrations and pH values of ethanol solution also had been investigated.The results of static tests indicated that DM21 resin was the most appropriate,and the best conditions were adsorption velocity of3 Bv,pH2.0~4.0,desorption solvent of 70% ethanol.The pigments content of purple potato extract purificated by DM21 resin were more than 54.26±0.87,in line with market requirements.
