超声波辅助提取诸葛菜籽油的工艺研究

Ultrasound-assisted extraction of Orychophragmus violaceus seed oil

以诸葛菜籽为原料,采用超声波辅助法提取诸葛菜籽油。通过单因素试验研究了提取溶剂、料液比、超声温度、超声时间对诸葛菜籽得油率的影响,并采用响应面试验优化了诸葛菜籽油最佳提取工艺条件。结果表明:以石油醚(60~90℃)为提取溶剂,在料液比1∶14.2、超声时间40 min、超声温度31.8℃的条件下,诸葛菜籽得油率最高,达到45.36%。超声波辅助提取法优于索氏提取法。

Orychophragmus violaceus seeds were used to extract oil by ultrasound -assisted extraction method. The effects of extraction solvent, ratio of material to liquid, ultrasonic temperature and ultrasonic time on the oil yield of Orychophragmus violaceus seeds were studied by single factor experiment and the extraction process was optimized by response surface methodology. The results showed that under the conditions of using petroleum ether（60 -90℃ ） as extraction solvent, ratio of material to liquid 1： 14.2, ultrasonic time 40 rain and ultrasonic temperature 31.8℃, the oil yield of Orychophragmus viohtceus seeds was the highest, reaching 45.36%. Ultrasound - assisted extraction method was better than Solhet extraction method.
