Abstract
1. In a process for preparing isomaltulose (6-0-alpha-D-glucopyranosido-D-fructose) wherein sucrose solution is treated with or brought into contact with dead immobilized cells of a microorganism and the formed isomaltulose is obtained by crystallizing characterized in passing one part of the sucrose solution having a concentration of 40% by weight to 75% by weight, preferably 45% by weight to 60% by weight via a reactor, which is filled with immobilized dead cells at 25 degrees C to 40 degrees, preferably 30 degrees C to 40 degrees C so that 80% to 90% of the sucrose is converted, in passing the first mother liquor obtained after having crystallized the formed isomaltulose with a further part of the sacrose solution via a second reactor, which is also filled with immobilized, dead cells at 25 degrees C to 40 degrees C, preferrably 30 degrees C to 40 degrees C so that the sucrose is almost completely converted, and by obtaining the isomaltulose resulting from the second part of the solution in crystalline form by methods known per se, in dissolving and crystallizing the crystals in the converted first part of the solution and in separating the resultant isomaltulose crystals.
