Abstract
A method for the enzymatic synthesis of sucrose ester, comprises introducing, in an adapted reactor and so as to form a reaction medium, predetermined amounts of an organic solvent, a sugar or a sugar derivative, a compound donor of acyl groups and an enzymatic catalyst, the amount of at least one constituent of the reaction mixture being deficient, in controlled addition during the reaction of additional amounts of the deficient constituent(s), and finally purifying the resulting sucrose esters at least by separating the fine enzymatic particles from the solvent.
