A process for decolorizing sugar solutions by contacting them with highly crosslinked, macroporous copolymers functionalized with weak-acid or weak-base ion exchange functional groups is disclosed. Treatment of sugar syrups using macroporous functionalized adsorbents allows for multiple regeneration cycles without loss of sugar decolorization properties.
L'invention porte sur une méthode pour décolorer des solutions de sucre en les mettant en contact avec des copolymères macroporeux hautement réticulés, fonctionnalisés avec des groupes d'échange ionique de type acide faible ou base faible. Le traitement de sirops de sucre à l'aide d'adsorbants fonctionnalisés macroporeux permet d'obtenir des cycles de régénération multiple sans perdre les propriétés de décoloration du sucre.
