| Abstract: | The linseed oil is achieved by using the supercritical CO2 extraction technique in this paper and the optimum conditions of orthogonal experiment are as follows：CO2 flow is 25L/h, extraction pressure 30MPa, extraction tempreture 45℃ ,extraction time 2 hours. Under these conditions, the experimental result shows that the average extraction rate is 36.7% and the extracted linseed oil is golden in colour and transparent. |
