| Abstract: |
| Using red melon seeds as raw material and extraction rate of red melon seed oil as index, the extraction technology of red melon seed oil was optimized by single factor experiment and orthogonal experiment, and the fatty acid composition of red melon seed oil was analyzed. The results showed that the optimal extraction process of red melon seed oil by supercritical CO2 were obtained as follows: particle size of red melon seed kernel 40 meshes, extraction pressure 40 MPa, flow rate of CO2 24 L/h, extraction temperature 50℃, extraction time 3.5 h. Under these conditions, the extraction rate of red melon seed oil was 99.27%. The unsaturated fatty acids content of red melon seed oil reached 79%, mainly including linoleic acid （62.1%） and oleic acid （16.3%） and it could be used as a kind of high quality vegetable oil for development and utilization. |
