摘  要:
柑橘皮内含有丰富的活性物质,如色素、黄酮类、香精油、果胶等物质,具有多重生理功效。试验以柑橘皮为原料,用95%乙醇为溶剂,在磁场条件下提取柑橘皮中的活性物质,以活性物质的得率为评价指标,进行单因素试验,研究萃取时间(0.5h、1h、1.5h、2h)、磁感应强度(90mT、140mT、270mT、360mT、450mT)、温度(45℃、50℃、55℃、60℃)、料液比(1∶5、1∶6、1∶7、1∶8)对柑橘皮中活性物质得率的影响。在单因素考察基础上,进行正交试验设计。结果表明:柑橘皮中活性物质提取的最佳提取条件分别为:温度60℃、料液比1∶7、磁感应强度140mT、萃取时间2h,此时得率为14.5%。

摘  要:
Orange peel is the remaining by-products when orange after being processed. Orange peel is rich in active substance such as pigment, flavonoids, essential oils and pectin which have multiple effi cacy of physiology. In this study, orange peel as raw material and 90% alcohol as solvent, extract the active substances from orange peel under magnetic fi eld. With the yield of active substances as the evaluation index, The extraction time(0.5h、1h、1.5h、2h), magnetic induction intensity(90mT、140mT、270mT、360mT、450mT), temperature(45℃、50℃、55℃、60℃ ) and liquid ratio(1:5、1:6、1:7、1:8) on the yield of active substances were investigated. The optimal conditions of extraction of active substance from orange peel under magnetic fi eld were obtained by orthogonal experiments. The result indicates: extraction time 2h, magnetic induction intensity 140mT, temperature 60℃ , liquid ratio 1:7 was the optimal extracting solvent. In this condition, we can get the maximum the extracting rate of onion oil, which is 14.5%.
