Rapeseed meal was used as raw material in this experiment. First, solid - state fermentation of ordinary rapeseed meal with single strain and multi-strains with lactic acid bacteria, aspergillus o- ryzae, aspergillus niger were carried. Then, using the prolease which was producing during the mixed fermentation to enzymatic hydrolysis, the contents of amino acids could be reached 1.15 g/100 ml during enzymatic hydrolysis at 55 ℃ for 7 h. Then, introducing a proper quantity of hydrochloric acid to acid hydrolysis at 95 ℃ for 8 h, the contents o...
