The method for acquiring an oxidation product and a reduction product from a saccharide

The present invention provides a process for obtaining n+a oxidation and reduction products from a mixture of n sugars selected from the group consisting of C5 and C6 sugars， where n is at least 2 and a is at least 1， wherein at least two of the sugars are present in the mixture in a non-equimolar ratio to one another， wherein， in a first stage， at least one of the sugars that are present in a non-equimolar ratio to one another is enzymatically oxidized and， at the same time， at least one of the other sugars that are present in a non-equimolar ratio to one another is enzymatically reduced and wherein， in the first stage， a portion of at least one of the sugars that are present in a non-equimolar ratio to one another is not converted， and which is characterized in that， in at least one second stage， at least a portion of the sugar unconverted in the first stage is half enzymatically oxidized and the remaining half is enzymatically reduced.
