A process for decolorizing an aqueous sugar solution containing color bodies, comprising the step of contacting an aqueous sugar solution with an effective amount of an adsorbent resin so as to adsorb color bodies from said aqueous sugar solution onto said adsorbent resin, wherein said adsorbent res

A process for decolorizing an aqueous sugar solution containing color bodies, comprising the step of contacting an aqueous sugar solution with an effective amount of an adsorbent resin so as to adsorb color bodies from said aqueous sugar solution onto said adsorbent resin, wherein said adsorbent resin is made from a macroporous copolymer of a monovinyl aromatic monomer and a crosslinking monomer, where the macroporous copolymer has been post-crosslinked in the swollen state in the presence of a Friedel-Crafts catalyst and functionalized with hydrophilic groups.
