CA 2632659

A novel process is described for production of 6-acyl-sucrose comprising enzymatic acylation of sucrose by an esterifying agent including an organic acid in presence of a lipase or an esterase in a solvent in which the enzyme used is stable. Chlorinated sucrose, the high intensity sweetener trichlorogalactosucrose can be prepared by chlorination and deacylation of 6- acyl sucrose prepared by the process of this invention.

La présente invention concerne un nouveau procédé de production de 6-acyl-saccharose comprenant une acylation enzymatique du saccharose par un agent d'estérification comprenant un acide organique en présence d'une lipase ou d'une estérase dans un solvant dans lequel l'enzyme utilisée est stable. Le saccharose chloré, l~édulcorant d~intensité élevée trichlorogalactosaccharose peut être préparé par la chloration et la désacylation du 6-acyl-saccharose préparé au moyen du présent procédé.
