Abstract
Process for manufacturing crystallized sugar from an aqueous sugar solution containing colorants, polyvalent cations such as Ca.sup.2+ and Mg.sup.2+ ions and possibly polyvalent anions, said process comprising the step of submitting said solution to a crystallization procedure to obtain a crystallized sugar, the process being characterized in that, in order to decrease the occlusion of colorants in the crystals of said crystallized sugar, it further comprises the step of treating said solution so as to increase the number of polyvalent anion equivalents such as adding CO.sub.B.sup.- anions with regard to the number of polyvalent cation equivalents in said solution.
