浓香型大曲酒生产中正丁醇生成量差异的原因

在长期的浓香型大曲酒生产中，发现新窖泥发酵糟醅所产酒中正丁醇的含量远远超过老窖泥发酵糟醅所产酒的正丁醇含量。为此，对使用新老窖泥造成正丁醇生成量差异的原因进行了分析研究。结果表明，新窖泥生成正丁醇的能力不但远远超过老窖泥，丁酸乙酯的生成能力也明显高于老窖泥。探明了新老窖泥生成正丁醇能力差异的主要原因是由于老窖泥中某种物质的含量过高所致。(丹妮)

Reasons of Different Content of Normal Butyl Alcohol During the Production of Luzhou-flavor Daqu Liquor

It was found that in the production of Luzhou-flavor daqu liquor,the normal butyl alcohol content in liquor produced by new pit mud was far beyond than that in liquor produced by aged pit mud.Accordingly,the production volume variance of normal butyl alco hol by new and aged pit mud was analyzed and the test results indicated that compared with aged pits mud,new pit mud had not only stronger normal butyl alcohol-producing capability but also stronger ethyl butyrate-producing capability.The main variance of new pit mud and aged mud was the relatively higher content of certain substance in aged pit mud.(Tran.by YUE Yang)
