摘　　要：以磷酸水解蔗髓提取L-阿拉伯糖和D-木糖,利用模拟移动床色谱(SMB)分离技术连续分离蔗髓提取液的木糖结晶母液。以钙型树脂为分离剂,纯水为洗脱剂,在最优参数下实现了L-阿拉伯糖和D-木糖的分离,SMB出口产品纯度分别达到81.94%和91.89%,均达到结晶要求。该工艺产品提取率高、纯度高,操作简便,运行成本低,水解液及离子交换洗脱液中的磷酸根经处理可回用甘蔗制糖澄清工艺,不产生废液排放,实现了磷酸的资源化循环利用,有效解决了L-阿拉伯糖传统生产工艺中的环保问题,同时也开辟了L-阿拉伯糖生产原料的新领域,适合工业化生产。L-arabinose and D-xylose were extracted from bagasse pith by phosphoric acid. Continuous fractionation of xylose crystalline mother liquid from extraction of bagasse pith by simulate moving bed chromatography. The Ca2＋ resin was used as a separation agent and water was eluent. L-arabinose and D-xylose were separated with the best parameters and product purity was 81.94% and 91.89% which can be crystallize. This process was high extraction rate and purity, easy operation and low running cost. The phosphate which in hydrolysate and ion exchanging eluate can be reused in clarification process of cane sugar. There is no discharge of waste liquid and phosphoric acid was realized resource recycling. This process effectively solved the environmental protection problem of L-arabinose traditional processing technology, and opened up a new field of raw material for L-arabinose and suitable for industrialized production.
