摘要:
以豆瓣辣酱微生物区系中已分离鉴定的5株优势霉菌M2~M6为试验菌株，通过筛选高产蛋白酶和肽酶菌株，并将之应用于发酵豆醅，对比传统发酵以探索其在缩短周期、促进风味及提高品质等方面的应用可行性。研究表明：M3产蛋白酶活力达到139.49 U/mL；M6肽酶活力达1.039 mg/dL。采用高酶活菌株进行人工接种菌群强化发酵蚕豆，促熟效果显著，发酵时间缩短至20天（传统周期为60~90天），M3组呈味氨基酸含量达56.63%，M6组为48.03%，而传统优质CK组仅为45.23%，差异显著（P＜0.05）。
Abstract:
Take the five dominant moulds M2~M6 separated and identified f rom microflora of bean chili sauce as test strain s, screen high-yield protease and peptidase strains and apply them for fermenting bean fermented grains, i n order to explore the application feasibility of shortening fermentation period, promoting flavor and improving quality compared with the traditional fermentation. The protease activity of M3 reaches 139.49 U/mL and the peptidase activity of M6 reaches 1.039 mg/dL. The fermentation time is shortened to 20 days (the traditional fermentation period is 60~90 days ). The content of amino acid in M3 group is 56.63% and that in M6 group is 48.03%. At the same time, that of the traditional high-quality CK group is only 45.23%, the difference is significant (P <0.05)
