摘要
目的 考察三种大孔吸附树脂分离番茄红素和 β-胡萝卜素的效果 ,优选大孔吸附树脂。方法 比较D4 0 2 0、X- 5和 AB- 83种大孔吸附树脂对番茄红素和β-胡萝卜素的吸附和解吸性能 ,同时研究相应的动力学过程。结果 X- 5树脂对番茄红素和 β-胡萝卜素的吸附量最大 ,分别是 7.4 4和 11.2 m g/g,并且 X- 5树脂的解吸率最高。结论 X-
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 carotene with 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 an ideal adsorbent for lycopene and β carotene extraction.
