摘要： Radio frequency (RF) is an emerging technology for rapeseed pretreatment, offering a comparison to the established microwave (MW) technique. This study investigated the effects of RF and MW pretreatment combined with different oil extraction methods on the oil yield, quality characteristics and lipid concomitant contents of rapeseed and its products. Results indicated that RF combined with pressing extraction yielded the highest tocopherol and canolol contents in rapeseed oil (839.6 and 1316.4 mg/kg, 8.0 % and 7.9 times higher than the control, respectively), and MW combined with supercritical carbon dioxide fluid extraction yielded the highest phytosterol content (8402.0 mg/kg, 16.6 % higher than the control). These results indicate the effectiveness of RF as a novel pretreatment method for rapeseed and its potentially greater advantage than MW. Results also imply that RF could contribute to sustainable and efficient oil extraction processes in the future food industry owing to its high efficiency and energy-saving capability.
