摘  要:
采用蒸馏法,对山西老陈醋整个生产过程中酒精与醋酸发酵阶段酒精度的变化进行了分析测定。结果表明,山西老陈醋在酒精发酵第2天即生成大量的酒精,酒精度达到5.0%,而后在酒精发酵结束(后发酵15 d)时,酒精度达到最大(7.0%~8.5%);醋酸发酵阶段,酒精缓慢减少,待醋酸发酵至第9天时酒精基本无残留,酒精转化完全,发酵结束。酒精度是酒精发酵阶段与醋酸发酵阶段的严控指标。

摘  要:
The alcohol content was analyzed by distillation in the alcohol and acetic acid fermentation production process of Shanxi mature vinegar. The result showed that there were a lot of alcohol generated on the second day in alcohol fermentation, the alcohol content was 5.0%, and alcohol content was maximum(7.0%-8.5%)at the end of the alcohol fermentation(15 days). The alcohol content decreased slowly in the acetic acid fermentation stage because alcohol changed into acetic acid, on the ninth day the alcohol content was zero, the alcohol was changed completely. The alcohol content was controlled index in the stages of alcoho and acetic acid fermentation.
