Abstract:The possibility of extracting essential oil from the oiliness layer of Meizhou Shatian shaddock peel by subcritical 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 of terpenes, in which D- limonene showed the highest content of 81.27%.
