| abstract |
The present invention relates to a process for purifying a carbohydrate composition, comprising an electrochemical treatment of this composition in an apparatus having at least two membranes 3, one anode 1 and one cathode 2, the membranes 3 forming at least three compartments, with the anode in an anode compartment 4, the cathode in a cathode compartment 5 and an intermediate compartment 6 between these compartments, wherein the carbohydrate composition is passed through intermediate compartment 6 and both membranes 3 have an ion exchange capacity of less than 0.3 meq/g. The present invention further describes an apparatus for performing the process. |
