为了更好地利用蚕蛹,增加其附加值,以蚕蛹蛋白为原料,采用纳豆菌发酵蚕蛹蛋白,制备低分子蚕蛹蛋白肽,并对其发酵工艺进行优化和建模,使蚕蛹蛋白肽的产量得到了提高。最终确定最优发酵条件为:发酵温度为36.9℃,发酵pH 7.3,接种量为3%,发酵时间为21.7 h,在此条件下蚕蛹蛋白水解低分子蛋白肽得率可达到52.75%。 In order to make better use of silkworm pupae and increase its added value, the silkworm pupa protein was prepared by fermentation of silkworm pupa protein using nattokinase as raw material, and the low molecular weight pupa protein peptide was prepared. The fermentation process was optimized and modeled, Has been improved. The optimal fermentation conditions were: fermentation temperature 36.9 ℃, fermentation pH 7.3, inoculum size 3%, fermentation time 21.7 h, under which the yield of proteolytic low molecular protein peptide from pupae reached 52.75%.
