双乙酰还原性好的酵母菌株的选育

Breeding of Yeast Strains with Good Diacetyl Reducing Capacity for Beer

应用微生物稀释培养法,对生产现场酵母进行了筛选和纯化培养,选出双乙酰还原性能好的酵母菌株。对该菌株进行了相关发酵力分析,并进行发酵成品品尝。最后确定双乙酰还原好的酵母菌株用于生产上,达到理想的效果,从而提高了啤酒风味稳定性。

Yeast strains on the production field were screened and cultured by diluting culture of microorganism to obtain the strain with good diaeetyl reducing capacity. The fermenting power of such strain was analyzed and the tasting of product beer fermented by such strain was performed. The results indicated that the use of such strain in beer production could achieve ideal effects and improve beer flavor stability.
