浓香型白酒双层平台制曲工艺研究

通过生产实践和研究发现,利用双层平台制曲工艺可让大曲生产的顶温达到61～63℃,在不影响偏高温大曲感官指标的同时,使各项理化指标更为协调,不仅满足了对大曲产量的要求,同时提高了浓香型白酒的质量。结果表明,利用双层平台制曲工艺所生产的大曲用于酿酒,一车间优质率提高1.2%,二车间优质率提高1.6%,三车间优质率提高1.8%,3个车间原酒优质率平均提高1.5%。

Investigation on Double-platform Starter-making of Luzhou-flavor Liquor

In double-platform starter-making,top temperature in Daqu production could reach up to 61～63 ℃,and the physiochemical indexes of produced Daqu were more harmonious without any adverse effects on Daqu sensory indexes,which could not only meet the requirements of Daqu yield but also improve the quality of Luzhou-flavor liquor.Production practice suggested that as double-platform starter-making performed in three workshops,quality base liquor rate in No.1,No.2 and No.3 workshop increased by 1.2 %,1.6 % and 1.8 % respectively,and the average quality base liquor rate in the three workshops increased by 1.5 %.
