聚乙二醇淀粉糖苷的合成及其保湿性

Synthesis and Moisture Retention of Polyethylene Glycol Glycoside from Starch

摘要:

以马铃薯淀粉和聚乙二醇为原料，采用转糖苷化法合成聚乙二醇淀粉糖苷，以糖苷产率为指标，通过正交实验探讨最佳合成工艺条件为反应温度118℃，反应时间4.5h，淀粉、对甲苯磺酸、乙二醇、聚乙二醇800的质量配比为1∶0.025∶4∶2，糖苷产率达154.58%；对产品进行FT-IR，GC-MS结构表征和保湿性能分析。结果表明，该产品属糖苷类物质且具有良好的保湿性能。

Abstract:

In this paper,potato starch,polyethylene glycol were used as the raw materials,adopting trans- glycosylation to synthesize polyethylene glycol glycoside,with the yield of the target product as the research index,the optimum conditions of synthesizing polyethylene glycol glycoside were investigated by orthogonal as follows: reaction temperature 118℃, reaction time 4.5h, m(starch):m(PTSA): m(ethylene glycol):m(PEG800)=1:0.025:4:2.The yield of the target product was 154.58%.The product was characterized with FT-IR, GC-MS and the moisture retention was analyzed. The results showed that the product belong to a kind of glycosidic substances, and the product with excellent moisture retentiveness was obtained.
