In this study the use of pressurized ethanol to extract oil from radish seeds was investigated. The influence of the pretreatment of the seeds and the ethanol flow rate, static time, temperature and pressure applied during the extraction was evaluated to determine the effect on the yields of oil and active compounds. The application of thermal treatment after immersion promoted an increase in the oil yields. An ethanol flow rate of 3 mL min⁻¹ and a static time of 10 min increased the oil diffusion. The extraction at 150 °C provided a high oil fraction and higher yields of phytosterols and γ-tocopherol were obtained at 135 °C. In addition, 5 MPa was sufficient to achieve an oil yield of 36.6%, as higher pressures did not influence the process. The oil obtained was rich in oleic and erucic acids, with low acidity and high oxidative induction time.

在这项研究中，研究了使用加压乙醇从萝卜种子中提取油。评估了种子预处理和提取过程中施加的乙醇流速、静态时间、温度和压力的影响，以确定对油和活性化合物产量的影响。浸渍后热处理的应用促进了油产量的增加。乙醇流速为 3 mL min ^-110 分钟的静态时间增加了油的扩散。在 150 °C 下提取提供了高油分，并且在 135 °C 下获得了更高的植物甾醇和 γ-生育酚收率。此外，5 MPa 足以达到 36.6% 的油收率，因为更高的压力不会影响该过程。所得油富含油酸和芥酸，酸度低，氧化诱导时间长。
