Abstract
A method of crystallizing fructose from an aqueous glucose-containing solution thereof as an impurity, comprising the steps of: (a) providing an aqueous fructose solution containing glucose as an impurity and at least about 90 percent dry substance, with the fructose content in the dry substance at least about 90 weight percent; (b) adjust the pH of the solution to a value between 4.0 and 6.0, preferably 4.5 and 5.5; (c) bringing the aqueous fructose solution to a temperature at which it is saturated with respect to fructose; (d) adding fructose seed crystals to the solution; (e) reducing the temperature of the resulting mass, at a controlled rate, to make the mass supersaturated with respect to fructose, and to cause an increase in the crystal size of the seed crystals without substantial formation of new fructose crystals ; and (f) separating the fructose crystals from the mass, when the crystal size is between approximately 200 and 500 μm.
