Abstract
The invention relates to a method for the production of crystalline fructose. The method comprises the steps of adding ethanol to a concentrated fructose solution; evaporating the mixture to a degree of supersaturation of at least 1.02; and adding anhydrous fructose seed crystals; removing ethanol-water azeotrope at a reduced pressure while maintaining the solution at a substantially constant temperature ranging from 50.degree. C. to 75.degree. C. so as to crystallize fructose; and recovering crystallized fructose, e.g. by centrifugation.
