The invention concerns a process for the preparation of a sorbitol rich syrup having less than 0.2% on ds of total reducing sugars, wherein said process comprises the following steps: (i) hydrogenation of a glucose syrup having a glucose content of 94% to 97% on dry substance (d.s.), (ii) separation step of the hydrogenated glucose syrup by at least one membrane nanofiltration stage to obtain a permeate and a retentate, wherein the permeate is a sorbitol rich syrup having at least 99.2% by weight on ds of hexitol, less than 0.2% by weight on ds of total reducing sugars and less than 0.3% by weight on ds of sugar alcohols having a molecular mass higher than hexitols. The invention also concerns a sorbitol rich syrup having at least 99.2% by weight on ds of hexitol, less than 0.1% by weight of total reducing sugars on ds and less than 0.2% by weight on ds of sugar alcohols having a molecular mass higher than hexitols. |
