摘要：

An efficient process was developed for enrichment of tocols from rice germ oil (RGO) using supercritical carbon dioxide (SC-CO2). Tocols were efficiently enriched in residue by removal of fatty acid methyl ester from the esterified RGO using SC-CO2. The enrichment of tocols was carried out at an operating pressure of 12.415.8 MPa, an operating temperature of 4060 degrees C and a carbon dioxide flow rate of 5.0 L min-1. The combination of 13.8 MPa pressure and 60 degrees C temperature was selected as the most suitable for efficient enrichment of tocols. The level of tocols (1270 mg/100 g) in the residue obtained at these operating conditions was six times higher than the tocols level (192 mg/100 g) of the starting material, namely esterified RGO. There were no significant differences in relative percentages of tocols homologues between esterified RGO and the residue obtained by SC-CO2 extraction.
