Abstract
The invention relates to a method for manufacturing a sorbitol syrup having a total reducing sugar content no higher than 0.2% and mannitol content of less than 1%, with 70 wt % of dry matter. Said manufacturing method is characterized in that it includes the steps of: (a) hydrolyzing a solution of sucrose in a solution of invert sugars, (b) separating the solution of invert sugar by simulated moving bed chromatography into, on the one hand, a dextrose syrup having at least 99.3%, preferably 99.4%, more preferably at least 99.5%, and even more preferably 99.7% of dextrose content and, on the other hand, a fructose syrup having at least 90%, preferably 92% of fructose content, and (c) hydrogenating said dextrose syrup into a sorbitol syrup having a reducing sugar content no higher than 0.2% and a mannitol content of less than 1%, with 70 wt % of dry matter.
