PURPOSE: A process for decolorizing sugar juice by means of monodisperse anion exchangers is provided to treat a colored sugar juice with a monodisperse anion exchanger and decolorizing the sugar juice. CONSTITUTION: The process includes the step of treating a colored sugar juice with a monodisperse anion exchanger and decolorizing the sugar juice. Here, the monodisperse anion exchanger is selected from the group consisting of microporous bead polymers, gel-type bead polymers and macroporous bead polymers. Also, the treating of the colored juice includes (i) flushing monodisperse anion exchangers into a heatable glass filter tube, (ii) heating the system from about 20deg.C to about 100deg.C, (iii) filtering the aqueous sugar solution to be decolorized via the adsorber resin bed in the loading direction from top to bottom or in reverse flow direction, and draining off adsorber resin with deionized water and finally, (v) regenerating the adsorber resin.
