Abstract
A process for the preparation of partially acylated derivatives of sucrose by the enzyme catalyzed deacylation of sucrose esters, wherein said process comprises treating a sucrose ester selected from the group consisting of sucrose octaacylate, sucrose heptaacylate, and sucrose hexaacylate in an anhydrous organic medium, with an enzyme or combination of enzymes capable of catalyzing the deacylation of said sucrose ester to produce a partially deacylated sucrose derivative having free hydroxyl group(s) in pre-selected position(s), and recovering the resulting partially deacylated sucrose derivative.
