摘要

PURPOSE: A method of extracting sesame oil having a high content of sesamol as an antioxidant from sesame using supercritical carbon dioxide and ethanol is provided. It permits the production of the titled sesame oil in high efficiency. CONSTITUTION: Sesame is roasted for 30min or more at 200deg.C or more and ground to a particle size of 1.25mm or less. Thereafter, the roasted sesame powder is extracted in supercritical carbon dioxide at a temperature of 30 to 80deg.C, a pressure of 500bar and a flow rate of 0.0085m/sec or less. In the process, 1.0% or less of water is used as an auxiliary solvent. Thus obtained sesame oil has a sesamol concentration of 465mg/L or 805mg/L.
