摘要
[目的]对香蕉皮中多酚物质的提取工艺进行研究。[方法]考查提取溶剂浓度、时间、温度、料液比等影响提取率的几个重要因素,通过单因素试验和正交试验确定最佳提取工艺参数。[结果]以乙醇溶液为提取剂,影响香蕉皮中多酚提取的因素由大到小依次为:乙醇浓度>浸提温度>提取时间>料液比,最佳工艺条件为:乙醇浓度80%,料液比1:3,提取时间2.5h,浸提温度70℃。[结论]香蕉皮多酚提取最佳条件的确定,为更好地利用香蕉资源以及香蕉皮多酚的工业化制备提供一定的参考。
[Objective]The extraction technology of polyphenols from banana peel was studied.[Method] The solvent concentration,extraction period,temperature and ratio of material and water were determined by orthogonal test.[Result]The ethanol concentration,the extraction temperature,the extraction period,the ratio of material and water were the main factors that affected the extraction rate with a sequence from big to small.The optimum extraction technology was determined such as 80% ethanol concentration,extraction period 2.5 h,extraction temperature 70 ℃,and ratio of material and water 1:3.[Conclusion] The determination of the optimum extraction technology provided the basis of the utilization of the banana resource and the industrial preparation of the polyphenols from banana peel.
