Abstract

Disclosed herein is a method for the separation of a mixed glucose-fructose solution into glucose and fructose by using a strongly acidic cation exchange resin of alkaline earth metal type and, more particularly, such method for the separation of glucose and fructose wherein said mixed glucose-fructose solution and water are supplied to and circulated through a bed of said cation exchange resin at least twice for increasing the distance between a zone of adsorption for glucose and a zone of adsorption for fructose that are formed in this way in the bed and, after such preliminary procedure, the glucose fraction and the fructose fraction of the effluent liquid are removed spotwise from the system while the remaining effluent fractions are again circulated in the order of efflux; at this time, the mixed glucose-fructose solution is injected spotwise into a portion of the liquid flow where the fructose content ratio is approximately equal to or slightly lower than that of the mixed glucose-fructose liquid, and water is injected into a portion of the liquid flow corresponding to the dilute fructose liquid, by way of such separation procedure, the latter step being carried out several times on end for sequentially taking out liquid glucose and fructose.
