| Sea buckthorn has become recognized as a specialty crop. A real need exists for the determination of feasible oil extraction technologies for sea buckthorn, evaluating processing, component extraction efficiency, and oil quality in terms of nutritional composition as related to processing, extraction, and economic feasibility.; An evaluation of oil extraction technologies, namely supercritical fluid extraction (carbon dioxide) (SCFE CO2), screw pressing, and an aqueous extraction technique was conducted, comparing oil recoveries and nutritional composition with a solvent extraction method employing petroleum ether. Supercritical fluid extraction using CO2, recovered oils having favorable levels of fatty acids, tocopherols and tocotrienols, carotenoids, and sterols, components which are highly valued in the health food industry.
