摘要：
Supercritical carbon dioxide (SC-CO2) extraction and simultaneous distillation extraction (SDE) were used to determine the volatile composition of Antarctic krill (Euphausia superba). The optimal extraction conditions for the oils yield within the experimental range of variables examined were temperature 40 C, pressure 60 MPa, and extraction time 150 min. The maximum measured extraction yield was 12.34 +/- 0.20 %. The chemical composition of the volatile compounds was adsorpted and analyzed by headspace solid phase microextraction (HS-SPME) and gas chromatography/mass spectrometry (GC/MS), respectively. A total of 35 compounds were identified including 2 alcohols, 6 aldehydes, 1 ketone, 2 furans, 4 acids, 2 amines, 5 aromatic compounds, and 13 hydrocarbons.
