Research advances in enzyme-catalytic synthesis of sugar ester in non-aqueous phase

The recent research progress of enzymatic synthesis of sugar ester is reviewed,by focusing on the methods for the synthesis of glucose ester,fructose ester,sucrose ester,maltose ester and xylitol ester.The impacts of enzyme,solvent and fatty acid on the yield of sugar ester are analyzed.The similarities and differences of enzymatic synthesis of different suger ester are compared.The outlook of enzyme-catalytic synthesis of sugar ester in the non-aqueous phase is also prospected.The enzymatic synthesis provides many advantages including mild reaction conditions,high selectivity,and low toxicity.New reaction medium,economic and environmental method of separation and purification are also emphasized.
