摘要
本研究在获得梅州金柚油泡层的基础上,就亚临界流体提取技术应用于柚皮油泡层精油的提取进行了探讨。研究结果表明:在提取温度40℃、油泡层烘干方式为60℃热风烘干或自然晾晒,油泡层含水量8.0%、提取次数2次的条件下,以丁烷为介质亚临界提取柚皮油泡层中的精油,精油得率达到2.36%;得到的柚皮精油为具有独特柚子芳香的黄色油状液体,GC-MS分析表明,该精油组分主要以萜烯类形式存在,其中含量最高的成分是D-柠檬烯,含量达到81.27%。
The possibility of extracting essential oil from the oiliness layer of Meizhou Shatian shaddock peel by subcfitical fluid was discussed in this study. The results showed that when the extraction temperature, oiliness layer drying method, oiliness layer water content and extrcing times were 40 ℃, 60 ℃ hot air drying or natural drying, 8% and 2, respectively, essential oil yield reached 2.36% by subcritical extraction technology with butane as medium. The shaddock peel essential oil was a yellow oil aromatic liquid with typical shaddock peel special flavour. GC-MS analysis showed that, the essential oil components mainly existed in the form ofterpenes, in which D- limonene showed the highest content of 81.27%.
