| Abstract: |
| Oil and protein were simultaneously extracted from cold-pressed dehulled double-low rapeseed cake by aqueous method.With extraction temperature，extraction pH，ratio of material to liquid and particle size of raw material as indicators，extraction rates of oil and protein as evaluation indexes，fixing extraction time 120 min，the aqueous extraction conditions were optimized by orthogonal experiment on the basis of single factor experiment as follows： extraction temperature 60℃，extraction pH 9，ratio of material to liquid 1∶7 and particle size of raw material 100-120 meshes. Under these conditions，the extraction rates of oil and protein were 64.59% and 59.63% respectively. |
