| Abstract: |
| The extraction amounts of Canolol, tocopherol and phytosterol were used as the indexes and the rapeseed cake was as material, the effects of mass ratio of r134a to butane were studied. The optimal extraction conditions were obtained by orthogonal experiment as follows: mass ratio of r134a to butane 6∶ 3, extraction temperature 45 ℃ and extraction time 30 min. Under these conditions, the extraction amounts of Canolol, total tocopherol and total phytosterol were 2.43, 9.71, 89.17 mg/100 g, respectively. |
