摘  要:
以新鲜的核桃仁为原料 ,研究了在超临界状态下物料的粉碎度、萃取压力、萃取温度、萃取时间对核桃油萃取效果的影响。结果表明 ,超临界 CO2 流体萃取核桃油的最佳工艺条件为粉碎度 3 0目、萃取压强 3 0 MPa、萃取温度 4 5℃、萃取时间 5 h,此条件下核桃油的萃取率可达 93 .98%。

摘  要:
Walnut meat was taken as experimental material of extraction condition. The influence of extracting pressure, temperature, time and material size on the extraction efficiencies of walnut oil was studied systematically. The results showed that, the efficient conditions of supercritical CO 2 fluid extraction were at 45℃, 30 MPa, 5 h. The extracting rate can be up to 93.98%.
