| Abstract: | The extracting study on pumpkin seed oil was carried with the supercritical fluid carbon dioxide extraction technique.The effects of raw material pretreatment, extraction pressure, temperature,time and SC-CO 2 flow on the extraction rate were investigated.The results of the experiments indicate that the optimum extraction pressure,temperature,time and SC-CO 2 flow for the maxium extraction was 30MPa,45℃,2.5 h,25 kg/h respectively.The components of the seed oil was determined by GC/MS,and the physical and chemical properties of the seed oil were analyzed .The results showed the product extracted with SC-CO 2 was superior to that with ether. |
