摘要
以柑橘果业加工废料橘皮为原料,以橘皮总黄酮得率为指标,通过单因素试验和正交优化,研究了超声辅助提取橘皮总黄酮的最佳工艺条件,以期为橘皮总黄酮的工业化生产提供理论指导。结果表明:超声波法提取橘皮中总黄酮的最佳提取工艺条件为:提取时间30min,乙醇浓度60%,料液比1∶25mg/L,此时,总黄酮的提取率可以达到9.6%以上。
Taking orange peel which was citrus fruit processing waste as raw material,the total flavonoids yield as index,with ultrasonic assisted extraction,through single factor experiments and orthogonal tests to optimum the extraction technology of total falvonoids from orange peel,in order to obtain optimum process conditions of orange flavonoid by ultrasonic assisted extraction and provide some theoretical guidance for the industrial production of flavonoids from orange peel.The results showed that for ultrasonic assisted extraction,the yield of orange flavonoid reached 9.6% under extraction conditions of extracting time 30 min,alcohol concentration 60%,solid to liquid ratio 1∶25 mg/L.
