Extraction of rapeseed cake oil using subcritical R134a/butane: Process optimization and quality evaluation
Abstract The optimal extraction conditions of rapeseed cake oil using subcritical R134a/butane were established by response surface methodology. The quality of subcritical R134a/butane extraction oil (SRBEO) was compared with supercritical CO2 extraction oil (SCO2EO) and hexane extraction oil (HXEO)...

The content of phospholipids and canolol in SRBEO (3.01 mg/g, 118.51 mg/100 g) was higher than SCO2EO (not detected, 95.82 mg/100 g) and less than HXEO (25.78 mg/g, 131.85 mg/100 g).
