摘　　要：为探索不翻曲的浓香大曲制曲方式是否可行,为浓香制曲实现机械化、智能化提供依据,在传统曲房中选择60块曲药作为试验曲不进行翻曲操作,通过翻动其他传统曲药为试验曲发酵创造适宜环境,对试验曲与对照曲不同发酵阶段曲药理化、微生物指标进行跟踪检测。结果发现,未进行翻曲操作的试验曲曲药内部水分散失速度、菌丝生长情况差异较小,最终出房时曲药质量与传统曲药相比在感官、理化指标等综合评分方面均无明显差异,曲药质量可达到传统制曲质量要求,通过小试试验验证了浓香大曲不翻曲的制曲方式是可行的。In order to explore the feasibility of making Nongxiang Daqu without Daqu-turning process,and to provide basis for the mechanized and intelligent production of Nongxiang Daqu,60 blocks of Daqu in the fermentation room were selected as the test Daqu,and the suitable environment for the fermentation of the test Daqu was created by turning other Daqu blocks in the room.The physicochemical and microbiological indexes of the test Daqu and the control Daqu at different fermentation stages were tracked and detected.The results showed that there was little difference in the internal water loss rate and mycelial growth conditions between the test Daqu and the control Daqu.There was no significant difference in the comprehensive sensory scores and physicochemical indexes between the test Daqu and the control Daqu when the fermentation was completed.The quality of the test Daqu could meet the quality requirements.In conclusion,it is feasible to make Nongxiang Daqu without Daqu-turning process.
