宋河酒业不同窖龄窖泥中微生物变化规律研究

Study on the Change of Microbial in Different Aged Songhe Distillery Pit Muds

研究以宋河酒业不同窖龄的窖泥为研究对象,通过分析不同窖龄中窖泥的微生物变化规律。在适宜范围内窖泥中的细菌总数随着窖池窖龄的增加而增加,且同一窖龄窖泥池底细菌总数均高于池壁细菌总数;在适宜范围内窖泥中的放线菌和酵母菌数量随着窖龄的增加而增加,且同一窖龄窖池池壁的放线菌和酵母菌数量均高于池底的放线菌和酵母菌数量;芽孢菌数量也随着窖龄的增加而增加,不同窖龄窖泥中霉菌的变化较小;随着窖龄的增加,窖池所产原酒质量明显提升。

In the study,the pit mud of Songhe Distillery which was used for different pit age where were taken from a factory affiliated to the Songhe Group.By analyzing the change of Microbial in Different Aged Songhe Distillery Pit Muds,the results showed that:with the increase of pit age,the number of bacteria increased in the appropriate range;in the same aged pit mud , the total number of bacteria in pit bottom mud were higher than the wall. Along with the pit age increasing ,the number of actinomycetes and yeast in pit wall mud and pit bottom mud also increased in the appropriate range;In the same aged pit mud , the total number of actinomycetes and yeast in pit wall mud were higher than the bottom;The number of spore bacteria increased in the appropriate range. in the different aged pit mud , mould was different,but not regular. Along with the pit age increasing , base liquor frompit mud quality improved significantly.
