The present invention relates to an improved process for the manufacture of Isomaltitol by hydrogenation of Isomaltulose. According to the process, a solution of Isomaltulose having a concentration in the range of between 20% to 50% by weight, is hydrogenated at a temperature in the range of between 80 DEG C. to 130 DEG C., using a catalyst selected from Ruthenium, Nickel and mixtures thereof on an inert support at a pressure below 50 atmospheres, the pH being maintained in the range of 3 to 8. The resulted product is substantially free from other polymers, Among the advantages of the process it should be mentioned the fact that it enables to achieve the desired ratio between the two isomers alpha -Glucopyranosyl-1,1-Mannitol (GPM) and alpha -Glucopyranosyl-1,6-D-Sorbitol (GPS). |
