Abstract
A process for decolorizing and demineralizing a sugar solution without the need for using cation exchange resins or activated carbon. The process includes the steps of contacting the sugar solution with a macroporous polymeric adsorbent having cationic functional sites to decolorize and demineralize the sugar solution, and contacting the sugar solution with an anion exchange resin to further demineralize the sugar solution.
