人工翻曲对发酵曲理化指标一致性影响的研究

Effects of Manual Daqu-Turning on the Consistency of Physiochemical Indexes of Fermented Daqu

对五粮液中温曲固定曲房不同位置取样,分析同一曲房中间和四周发酵曲的理化指标变化,研究人工翻曲对曲药质量的影响。结果表明,五粮液中温曲曲房不同位置的发酵曲各项理化指标差异较大,而通过3次人工翻曲最终使整间曲房的发酵曲在出房时质量趋于平均。

Fermented Daqu samples were obtained at different locations in Wuliangye medium-temperature Daqu culture room,the difference in physiochemical indexes among all the samples was analyzed,and the effects of manual Daqu-turning on the change of physiochemical indexes were further explored.The results showed that,there were great differences in physiochemical indexes of fermented Daqu from different locations in Wuliangye medium-temperature culture room,and through three times of manual Daqu-turning,the final quality of fermented Daqu in the whole culture room was average after room-exit.
