| 摘 要： | 采用可培养方法从传统酱香大曲和机械化酱香大曲中分离筛选酵母，并对这些酵母的数量、种类及功能差异进行分析比较。结果表明，机械化酱香大曲中酵母数量为传统酱香大曲的1.44倍；传统酱香大曲中酵母种类为机械化酱香大曲的2倍；相同条件下两者中产酒性能最高的酵母产酒精度在20 ℃时均为10.2%vol，机械化酱香大曲中筛选得到的酵母菌株平均产酒性能为传统酱香大曲的1.04倍；从产香上看，两种大曲中的产香酵母均能产生醇、酸、酯、酮类挥发性物质。 |

| Abstract: | The yeasts were screened and isolated from sauce-flavor Daqu made by traditional and mechanical methods. The quantity, species and functional differences of yeasts were analyzed and compared. Results showed that the quantity of yeasts in mechanical-made Daqu was 1.44 times than that in traditional-made Daqu; but the yeasts species in traditional-made Daqu was 2 times than that in the mechanical-made Daqu. In the same condition, the alcohol content of the highest performance yeast by both methods at 20 ℃ were 10.2%vol, the alcohol production capacity of yeasts screened from mechanical-made Daqu was 1.04 times than that from traditional-made Daqu in average. In aroma-producing aspect, both Daqu can produce alcohols, acids, esters and ketones. |
