Abstract: As one of the most potential green solvents,ionic liquid has been used as reaction medium in lipasecatalyzed synthesis with some unsurpassed advantages in comparison with traditional organic solvents.Based on the related literature on lipase- catalyzed synthesis of sugar esters in ionic liquid in recent decade,the review focused on summarizing common type of ionic liquids used in lipase- catalyzed ester synthesis,effect of ionic liquids on the activity,stability and selectivity of lipases,and enzymatically synthetic methods of sugar esters.Finally,further studies on enzymatic synthesis of sugar ester in ionic liquid were proposed.
