| 摘 要： | 本实验采用柱层析的方法对苹果渣中多酚和果胶分离进行了系统的研究。结果表明XDA-5型大孔树脂对多酚和果胶的分离效果最佳。其适宜的分离条件为:样品液pH值为2.0,最大上样量为5BV,上样流速3.0ml/min,样品洗脱的最佳乙醇浓度为60%,以1.5ml/min速度洗脱时,洗脱液量为2.5BV为洗脱终点。

| Abstract: | In this study, the method of separation of polyphenols and pectin from apple pomace by acid-extraction were researched. The polyphenols and pectin were separation. The result shows that the macroporous resin adsorbent XDA-5 was the optimal absorbent material. The optimum conditions of adsorption and desorption were: pH2.0 or so, the volume of sample 5.0 BV (resin bed volume) and the adsorption speed 3.0 ml/min, and the volume of 60%(V/V) ethanol as eluant was 2.5 BV with desorption-speed 1.5 ml/min. |
