| Abstract: | The rapeseed protein isolates from double-low defatted rapeseed meal by alkali-solution and acid-isolation were investigated,the experiment show that the optimal conditions is:The ratio of meal to solvent 1∶12,pH 11,extraction 4 times,temprature 50 ℃ and 35 min once. The content of protein is 86.12 %,the extraction rate of protein is 24.35 %,phytic acid and glucosinolate content become less. |
