ABSTRACT:
Sucrose or derivatives thereof such as esters are acylated at the 4'- and/or the 6-position by reaction with a donor acyl ester, e.g. a reactive ester of an alkanoic acid or benzoic acid, in the presence of lipase. Sucrose 6,4'-diesters so produced can be chlorinated and deacylated to produce the sweetener sucralose.
