Title (EN) PROCESS FOR PURIFYING SUGAR SOLUTIONS
(FR) METHODE DE PURIFICATION DE SOLUTIONS DE SUCRE
Abstract:
(EN) 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.
(FR) L'invention a trait à une méthode de décoloration et de déminéralisation de solution de sucre sans qu'il soit nécessaire de recourir à des résines échangeuses de cations ou à du charbon activé. La méthode consiste à mettre en contact la solution de sucre avec un adsorbant polymère macroporeux pourvu de sites fonctionnels cationiques pour la décolorer et la déminéraliser, puis à mettre cette solution en contact avec une résine échangeuse d'anions pour la déminéraliser une nouvelle fois.
