摘要
从优质老窖泥中筛选出纯种己酸菌、丙酸菌、丁酸菌扩大培养成纯种菌液,配合优质老窖中培养的复合菌液,通过正交试验确定出最佳优化组合为己酸菌液30%,丙酸菌液30%,丁酸菌液20%,优质窖泥培菌液40%,最佳培养时间为11d,最大产己酸量为4.2g/L。通过连续三排应用于普通窖池,使得窖泥中的各项指标均有所提高,所产原酒中酯类比例更加协调。
Pure caproic acid bacteria,propionic acid bacteria and butyric acid bacteria were screened from high-quality aged pit mud and expanded into pure bacterial solution.Mixed with compound bacteria liquid cultured with high-quality aged pit mud,the optimal combination was determined by orthogonal test as caproic acid bacteria solution 30%,propionic acid bacteria solution 30%,butyric acid bacteria solution 20%,high-quality pit mud culture solution 40%.The optimal culture time was 11 days and the maximum production of caproic acid was 4.2g/L.Through the application of three consecutive rows in ordinary pits,the indexes in pit mud are improved,and the proportion of esters in the original wine is more coordinated.
