摘要
以库房贮存为对照,将同一种浓香型基酒用陶缸分装好后,分别置于室内库房和露天平坝上贮存,贮存过程中跟踪分析两种环境下基酒的主要酸、醛、醇、酯的含量变化情况,以考察贮存过程中(6个季度)露天贮存对浓香型基酒的影响。结果表明,与库房贮存相比,露天环境对基酒中主要醇类物质和大部分酯类物质的含量影响很小。相反,露天环境对主要酸类物质和醛类物质的含量影响却是显著的。另外,从变化趋势上来看,浓香型基酒在两种环境下贮存时的酸、醛、醇、酯的含量变化趋势基本相同。感官品尝结果表明,库房贮存对基酒的去杂速度不及露天贮存。
Luzhou-flavor base liquor in pottery was stored in warehouse and on open-air ground respectively, tracing analysis of the change of the content of acids, aldehydes, alcohols, and esters of base liquor in storage period （6 quarters） was carried out, and the effects of different storage methods on Luzhou-flavor base liquor were investigated. Compared with base liquor stored in warehouse, open-air storage had little effects on the content of alcohols and esters, however, it had significant effects on the content of acids and aldehydes. The change trend of the content of acids, aldehydes, esters, and alcohols of base liquor stored in warehouse and on open-air ground was almost the same. Sensory taste results suggested that impurity-removal rate of base liquor stored in warehouse was inferior to that on open-air ground.
