Abstract
The present invention relates to a novel and inventive process for the production of sorbitol from D-sucrose.
Claims8
A process for producing D-sorbitol from sucrose, wherein the process comprises the steps of:
- (a) converting the sucrose to oxidized products substrate using glucose-fructose oxidoreductase (GFOR) enzyme;
- and thereafter
- (b) hydrogenating the oxidized products substrate in a hydrogenation step at a pressure of about 10 bar to about 60 bar and a temperature from about 30° C. to about 100° C. in the presence of a H2 gas and a transition metal-based complex selected from the group consisting of transition metal based complexes according to formulas (III) to (VIII):
