摘　　要：采用超临界CO2流体萃取技术,对番茄红素油树脂中的有机溶剂残留进行反向萃取。探讨了不同压力、温度、流量、时间对有机溶剂去除效率的影响,筛选出最佳去除条件:压力20 685.0 kPa,温度45℃,CO2流量2.0 L/min,提取时间4 h,溶剂最终去除率达89%。The organic solvent residue of lycopene oleoresin was removed with reverse supercritical CO2 fluid extraction under various combinations of pressure, temperature, flow rate of CO2 and extraction time. The optimal condition was as follows ：20 685,0 of pressure,45 ℃ of temperature, 2.0 liter/min of flow rate with the extraction time of 4 hours：As a result, about 89% solvent was removed from the lycopene oleoresin.
