超声波辅助超临界CO2提取枸杞籽油工艺条件研究

摘要

Wolfberry seeds were taken as raw materials and ultrasonic -assisted supercritical CO2 extraction technology was used to extract the seed oil.The optimal ultrasonic treatment parameters were investigated using single factor experiment and orthogonal experiment.Results revealed that the optimal parameters were obtained as follows: ultrasonic treatment temperature 60 ℃, ultrasonic power 300 W and ultrasonic treatment time 6 min.Under the optimal conditions,the oil yield reached 22.35％.%以枸杞籽为原料,采用超声波辅助超临界CO2提取枸杞籽油.以出油率为指标考察超声波处理条件的影响,在单因素试验基础上,通过正交试验优化超声波处理条件.结果表明,在超声波处理温度60℃、功率300 W、时间6 min的条件下,枸杞籽油的出油率可达到22.35%.
