中文摘要:
      研究了超声波辅助提取乌桕籽油的工艺条件。在单因素实验基础上，采用响应面分析法中的Box-Behnken法对影响油脂得率的主要因素进行优化。结果表明：影响乌桕籽油得率的因素主次顺序为提取温度>提取时间>超声波功率>料液比；优化的工艺条件为料液比1∶?11、提取温度47?℃、超声波功率210 W、提取时间100 min，在此条件下乌桕籽油得率可达36%左右。
英文摘要:
      The ultrasound-assisted extraction conditions of Sapium seed oil were studied. Based on single factor experiment, the main factors affecting oil yield were optimized by Box-Behnken method of response surface methodology. The results showed that the most significant factor was extraction temperature, followed by extraction time, ultrasonic power and ratio of material to liquid. The optimal extraction conditions were obtained as follows: ratio of material to liquid 1∶?11, extraction temperature 47?℃, ultrasonic power 210 W and extraction time 100 min.Under these conditions, the yield of Sapium seed oil reached about 36%.
