摘要：

Orthogonal test was used to evaluate the effects of synthetic such as temperature(120～140℃),reaction time(4-6)and substrate molar ratio of methyl oleate to sucrose(8:1-12:1)on the percent quantity conversion to sucrose polyester.Sucrose polyester was synthesized by a solvent-free one-stage interesterification.The optimum reaction conditions are as follows:methyl oleate/sucrose =10:1(mol/mol);reaction temperature is 140℃ ;reaction time is 5 hours.The product yield reaches 88.15%,and the degree of esterification(DE)is over 7 in the conditions.Thin layer chromatography(TLC),column chromatography(CC),High-performance liquid chromatography(HPLC)were used to analyze the product,the results show that the percent of sucrose polyoleate is over 70% in the product.The physicochemical properties of sucrose polyesters were compared with cooking oil.The results show that the qualities of sucrose polyesters are all up to the triglyceride.
