以水溶性膳食纤维聚葡萄糖为原料和3-氯-2-羟丙基三甲基氯化铵（QA-188）为阳离子醚化剂，合成阳离子聚葡萄糖，然后将其与胆汁酸进行吸附反应，并探讨了影响阳离子聚葡萄糖改性反应的因素及改性前后聚葡萄糖对胆汁酸的吸附性能的对比。结果表明：（1）用IR表征目标产物的结构，证实合成了阳离子聚葡萄糖；（2）阳离子聚葡萄糖改性反应的最佳条件为：聚葡萄糖∶醚化剂=40∶9（质量比），反应温度为60℃，pH为9～10，反应时间为3 h；（3）无论改性前后，随着聚葡萄糖用量增加，吸附率均呈先上升后下降趋势，达到一定程度时，其用量对吸附率影响不大。改性后的聚葡萄糖对胆汁酸的吸附率相对于改性前的聚葡萄糖有明显的提高。

Cationic polydextrose was prepared with a quaternary ammonium salt 3-chloro-2-hydroxypropyl trimethyl ammonium chloride (QA-188) as cationic etherifying agent, polydextrose in soluble dietary fiber as raw material, ethanol as solvent, let the product adsorption reaction with bile acid , the reaction of the factors discussed and compared before and after modification of polydextrose on bile acid adsorption. The results showed that:(1) Characterization confirmed by FTIR to obtain Cation polydextrose;(2) Product by measuring the degree of cationic substitution, optimum reaction conditions were∶m(polydextrose)∶m(etherifying agent)=40∶9, reaction temperature about 60℃, pH 9 to 10 and the reaction time 3 h;(3) With the increased use of polydextrose, adsorption rate increased at first and then reduced, to a certain extent, the amount of adsorption rate has little effect. bile acids adsorption rate polydextrose modified has a very significant increase relative to the polydextrose unmodified.
