摘    要:本文以蔗糖脂肪酸三酯(sucrose fatty acid triester,STE)和磷脂酰胆碱(phosphatidylcholine,PC)为原料制备蔗糖酯磷脂复合物,并通过傅里叶红外光谱分析(Fourier infrared spectrum,FT-IR)、热重分析(thermogravimetric analysis,TGA)和差示扫描量热分析(differential scanning calorimetry,DSC)对制备的蔗糖酯磷脂复合物进行表征分析;以STE为吸附脱磷剂,考察STE在菜籽油脱磷工艺中的应用。研究结果表明,STE与PC在无水乙醇体系中形成了新型的STE-PC复合物,与STE和PC相比,STE-PC复合物具有更低的相变熔融温度;另外,STE对菜籽油中的磷脂有一定的吸附脱除作用,在脱磷温度为55oC、STE添加量为3.5%、脱磷时间为30min条件下,脱磷率可达37.2%。

关 键 词:蔗糖脂肪酸三酯  磷脂酰胆碱  复合物  表征  脱磷

Abstract:In this paper, a kind of sucrose ester phospholipid complex was prepared with sucrose fatty acid triester (STE) and phosphatidylcholine (PC) as raw materials. And the sucrose ester phospholipid complex was characterized by fourier infrared spectrum analysis (FT-IR), thermo gravimetric analysis (TGA) and differential scanning calorimetry analysis (DSC). Then the application of STE in rapeseed oil dephosphorization process was studied. The results showed that in anhydrous ethanol system, STE and PC generated a new substance----STE-PC complex, which had lower phase change temperature than STE and PC. In addition, STE had some adsorption effects on phosphatide of the rapeseed oils. The dephosphorization rate was 37.2% when the dephosphorization temperature was 55oC, the STE adding amount was 3.5% and the dephosphorization time was 30min.
Keywords:sucrose fatty acid triester  phosphatidylcholine  complex  characteristics  dephosphorization
