| Abstract: | Choosing 1,1,1,2-tetrafluoroethane as the extractive agent,the experiment studied the optimum conditions of subcritical extraction technology using in the extraction of olive pomace oil.The effect of different materials granularity,extration temperature and time on extraction ratio was studied by using single factor test and three factors three levels orthogonal test.The results showed that the optimum conditions were as follows.The materials granularity was 60 mash;subcirtical extraction temperature was 30℃;and extraction time was 45min.Under these conditions,the extraction ratio of olive pomace oil was 93.75%. |
