Ion exchange enrichment of impure dextrose solutions

摘要

Mother liquors obtained from a dextrose crystallization process may be upgraded for re-cycling to dextrose crystallizers by transferring the mother liquor through a bed of an adsorption agent which preferentially adsorbs either dextrose or oligosaccharides. A dextrose-rich portion of the mother liquor is then recovered from either the dextrose-rich fraction which passes through the bed or has been preferentially adsorbed and eluted from the bed with a solvent.
