Abstract Monaacylglyceral is an imporlant nonionic: surfactant that has both hydrophilic groips and lipophilic groups
due te its good prperties in emulsion, dispersion and stabilization. Monoacylglycerol has a wide range of applicalion in
food industry, such as food emulsifiers and food additives. The synthetic tcchnology of lipas ( alalyzed synthesis of
monnaeyglycerol slated 1980 and is considered a novel technology. In recent years, with the development of biologi-
cal and chemical synthesis technology, enzymatic method gradually substitutes chemical method. In this paper, th
haracteristics of chemical method and enzymatic method are introduced. Several different enzymatic mehos smch as
esterification, glycerolysis, hydrolysis and transesterification are reported. As reaction systems. organic solvent, sol
vent -free, solid-phase, reverse micelles and super critical carbon monoxide are introduced. At last. the problems
and the prospe ls of the future develapment are prowse
