Analysis and synthesis of the sucrose ester
Journal Title: Science Paper Online - Year 2010, Vol 5, Issue 3
Abstract
Sucrose ester is a highly efficient emulsifiers and surface active agent and has a wide range of applications in the industry. This paper reviews the synthesis and analysis methods of sucrose esters. There are four ways to synthesize sucrose esters: solvent method, non-solvent method, microemulsification method and enzyme catalyst method. Solvent method and enzyme catalyst method involve poisonous solvent which restricts the applications of sucrose esters in food industry. Non-solvent method usually needs high reaction temperature which causes the materials caramelization and lowers the product quality. Microemulsification method is efficient and non-toxic production process. It uses propylene glycol or water as solvent instead of the toxic substances and makes the reaction system similar to be homogenous phase by adding emulsifying agents. The sucrose ester analysis methods are introduced including thin-layer chromatography, column chromatography, high performance liquid chromatography, infrared chromatography and so on. Their characteristics are summarized respectively.
