NOVELTY - Decolorization method of resolubilized syrup involves mixing quaternary ammonium functionalized chitosan/graphene oxide composite aerogel as an adsorbent with resolubilized syrup filtered by a ceramic membrane, stirring and filtering to obtain decolorized resolubilized syrup. USE - Decolorization method of resolubilized syrup in sugar industry. ADVANTAGE - The method solves the problem that the film separation technology for processing the back-dissolved syrup cannot intercept the small molecular pigment to cause the white granulated sugar color value of the finished product is high. The method realizes the green color of the sugar making process, at the same time, the quaternary ammonium functionalized chitosan/graphene oxide composite gas gel be circularly used after decolorizing treatment.
