ABSTRACT:
A process for chromatographic separation of dextrose from starch hydrolysate wherein the aqueous raffinate produced by contacting the starch hydrolysate with a chromatographic column or bed is treated with glucoamylase and recycled, at least in part, for use as an eluant for dextrose. An immobilized glucoamylase is used in the treatment to produce an aqueous dextrose-containing solution. It is this solution that is recycled and used, at least in part, as the eluant in the chromatographic column or bed used in the process.
