Object To study the separation effect of three macoroporous resins for lycopene and β-carotene, in order to optimize the suitable one. Methods The performances of adsorption and desorption for lycopene and β -caro tenewith three macroporous resins D4020, X-5 and AB-8 were compared, and adsorption dynamics process of resins was studied.Results The adsorptive capacities of X-5 resin for lycopene and β-carotene are the most,they are 7.44 and 11.2 mg /g, respectively. Desorption ratio of X-5 resin is the highest. Conclusion X-5 resin is anideal adsorbent for lycopene and β -carotene extraction.
