Abstract
In this study, the extraction of Conger myriaster oil by using supercritical carbon dioxide (SC-CO2) and organic solvent was investigated. The extraction conditions conducted for SC-CO2 varied for pressure (25, 30 MPa) and temperature (45, 55 ℃), while the SC-CO2 flow rate was kept constant during the experiment (27 g min-1) and hexane was used as a conventional organic solvent. The extraction yield indicated that the best extraction condition would be SC-CO2 at 55 ℃ and 30 MPa, resulting in the highest yield of 37.73 ± 0.14%. The oils were characterized for their fatty acid (FAs) composition using gas chromatography, while it was revealed that the major FAs were mystric acid, palmitoleic acid, oleic acid, electroosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). The oxidation stability of the extracted C. myriaster oil was evaluated by measuring the acid value, peroxide value, and free fatty acid. The best oxidative stability was obtained from SC-CO2 extracted oil at 30 MPa and 55 ℃. There was a significant difference in the color properties of the SC-CO2 and hexane extracted oils, with the SC-CO2 extracted oil showing better chromaticity than the oil extracted using hexane. Extracting oils from C. myriaster with SC-CO2 could bring better economic benefits than using organic solvents. When supercritical carbon dioxide was used, there was no post-treatment process; thus, it was confirmed that this is a more environmentally friendly oil extraction method.
