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.

A process for converting starch to dextrose comprising (a) hydrolysing an aqueous starch composition to a dextrose-containing starch hydrolysate; (b) contacting said starch hydrolysate with a chromatographic column or bed to absorb dextrose on said column or bed and to produce an aqueous raffinate;

A process for converting starch to dextrose comprising (a) hydrolysing an aqueous starch composition to a dextrose-containing starch hydrolysate; (b) contacting said starch hydrolysate with a chromatographic column or bed to absorb dextrose on said column or bed and to produce an aqueous raffinate; (c) eluting the dextrose with water; and (d) contacting the aqueous raffinate with an immobilized glucoamylase to produce an aqueous dextrose-containing solution, which is recycled, at least in part, and used as the eluant for said chromatographic column or bed.
