Objective To establish the kinetic model of adsorption patulin in pear juice by macroporous resin. Methods XDA-600 macroporous resin was used as adsorbent to adsorb patulin in pear juice, and the adsorption isotherms and adsorption thermodynamics and kinetics were analyzed. Results When the temperature was 25 °C, XDA-600 macroporous resin had good adsorption effect on patulin in pear juice. The adsorption thermodynamic model showed that macroporous resin adsorbed patulin in pear juice in accordance with Freundlich isotherm (r2>0.90), and the adsorption of patulin in pear juice by XDA-600 macroporous resin was more in line with the quasi-secondary rate equation. Conclusion XDA-600 macroporous resin is suitable for the adsorption of patulin in pear juice.
