摘　　要：The research explored the extraction techniques of organic solvents of Antarctic kril oil and the effects of freezing temperature, extractant proportion, ex-traction time, drying temperature and ratio of material and liquid on extraction ratio of Antarctic kril oil. Based on single-factor experiments, optimal extraction conditions were concluded as per response surface methodology, as fol ows： freezing tempera-ture at -38.5 ℃, the ratio of material and liquid at 1 g：6.7 ml, and drying tempera-ture at 66.8 ℃, where the yield rate of crude oil reached 13.71%.研究南极磷虾油有机溶剂提取工艺,探讨不同冻藏温度、提取剂比例、提取时间、干燥温度和料液比对南极磷虾油提取率的影响在单因素试验基础上,通过响应面法分析确定最佳的提取工艺条件:冻藏温度为-38.5℃、料液比为1 g∶6.7 ml干燥温度是66.8℃,此时南极磷虾油提取率为13.71%。
