A commercial subtilisin preparation was used in pyridine to catalyze the regioselective conversion of sucrose and fatty acid vinyl esters into the 1'-O-acyl sucrose derivatives. The 1'-O-lauryl sucrose, 1'-O-myristyl sucrose and 1'-O-stearyl sucrose were obtained as the major products of these reactions. The 1',6-di-O-acyl sucrose derivatives were also obtained as minor products. The critical micellar concentration (CMC) of each of these sucrose monoesters was determined.
