Abstract: This paper aims at presenting a review of the available literatures on the preparation technology of natural nonionic glycosyl surfactant sucrose esters(SE), such as acyl chloride esterification method, transesterification method and enzyme-catalysis method. It is pointed out that transesterification method is a mature technology which includes solvent method, water solvent method and solvent-free method. According to different methods, this review also describes the purification and detection presents the problem in the most convenient way and discusses the potential future research areas.

Key words: glycosyl, natural surfactants, sucrose esters
