摘　　要：该实验以乙醇-磷酸氢二钾双水相体系处理酒样,通过气相色谱-质谱(GC-MS)及聚类分析(CA)、主成分分析(PCA)法对46°、52°淡雅型和浓香型赊店老酒的香味成分进行了对比分析。结果表明,4种酒样共检出香气成分45种,包含15种酯类物质,14种醇类物质,9种酸类物质,5种醛酮类物质,2种烷烃类物质。在酯类聚类分析中,52°浓香型和淡雅型赊店老酒被归为一类,46°浓香型和淡雅型赊店老酒归为另一类;醇类和醛酮类聚类分析中,52°淡雅型赊店老酒中归为一类,52°浓香型、46°浓香型、46°淡雅型赊店老酒归为另一类;酸类聚类分析中,浓香型赊店老酒归为一类,淡雅型赊店老酒归为另一类。淡雅型和浓香型酒样区分度良好。In this experiment, Baijiu samples were treated in aqueous two-phase system of alcohol-dipotassium hydrogen phosphate, and comparative analysis of aroma components of elegant type and strong-flavor Shedianlaojiu with alcohol contents of 46% and 52% was carried out by GC-MS, cluster analysis(CA), and principal component analysis(PCA). The results showed that a total of 45 aroma components were detected in the 4 samples, including 15 kinds of esters, 14 kinds of alcohols, 9 kinds of acids, 5 kinds of aldehydes and ketones, and 2 kinds of alkanes. In the cluster analysis of esters, strong-flavor and elegant type Shedianlaojiu with alcohol contents 52% were classified into one category, strong-flavor and elegant type Shedianlaojiu with alcohol contents46% were classified into another category. In the cluster analysis of alcohols and aldoketones, elegant type Shedianlaojiu with alcohol content 52% was classified into one category, strong-flavor Shedianlaojiu with alcohol content 52% and 46%, and elegant type Shedianlaojiu with alcohol content 46% were classified into another category. In the cluster analysis of acids, strong-flavor Shedianlaojiu was classified into one category, elegant type Shedianlaojiu was classified into another category. Elegant type and strong-flavor Baijiu samples could be distinguished well.
