1. :
- A process for the synthesis of product saccharide in at least two reactors R1 and R2, the method comprising the steps of(i) supplying a liquid comprising educt saccharide to the reactor R1 and converting a portion of the educt saccharide to product saccharide under enzymatic catalysis thereby providing a liquid comprising product saccharide and residual educt saccharide;
(ii) separating at least a portion of the product saccharide from the residual educt saccharide of step (i) by liquid chromatography thereby providinga first chromatographic fraction comprising residual educt saccharide and optionally product saccharide; and
a second chromatographic fraction comprising product saccharide and optionally residual educt saccharide; and
(iii) supplying the first chromatographic fraction of step (ii) to the reactor R2 and converting at least a portion of the residual educt saccharide to product saccharide under enzymatic catalysis.

Abstract
The invention relates to a process for the synthesis of a product saccharide, preferably of D-allulose from an educt saccharide, preferably from D-fructose under heterogeneous or homogeneous catalysis which includes chemical and/or enzymatic catalysis. The synthesis is performed in at least two reactors that are arranged in series and the reaction product exiting the first reactor is subjected to chromatographic separation before it enters the second reactor. Preferably, the chromatographic separation is integrated in a simulated moving bed.
