Abstract: Rosin-based anionic exchange resin(RAER) was prepared by using modified rosin as the cross-linking skeleton, and quaternary ammonium cations as the functional group. And then, its adsorption performance on melanoidin which was arepresentative pigment in sugar juice was investigated. The four single factors(resin dosage, adsorption temperature, pH value and adsorption time) were optimized by the static adsorption experiments. When the initial mass concentration of melanoidin was 350 mg/L, the optimum adsorption conditions were resin dosage 0.06 g/mL, temperature 333 K, adsorption time 120 min and pH value 4.92. At the optimal adsorption conditions, the maximum adsorption capacity of melanoidins was 1.29 mg/g and the adsorption rate was 22.07%, which indicated that the rosin-based anionic exchange resin had superior adsorption performance on melanoidins.
