摘要
用全二维气相色谱/飞行时间质谱(GC×GC/TOFMS)研究白酒中微量成分,并对我国主要传统香型白酒中微量成分进行了比较。在相同条件下,酱香型白酒分出963个峰,浓香型白酒分出674个峰,清香型白酒分出484个峰。鉴定出酱香型白酒匹配度大于800的组分873种,浓香型白酒342种,清香型白酒178种。研究结果显示,GC×GC/TOFMS在白酒微量成分分析及白酒风格形成机理研究领域有很大的优势。
Full two-dimensional gas chromatography/time of flight mass spectrum （GCxGC/TOFMS） were applied in the analysis of microconstituents in liquor. Besides, the microconstituents in main liquors of traditional flavor were compared. Under the same conditions, there were 963 peaks, 674 peaks and 484 peaks in Maotai-flavor liquor, in Luzhou-flavor liquor, and in Fen-flavor liquor respectively. There were 873 kinds of microconstituents （matching degree above 800） in Maotai-flavor liquor, 342 kinds ofmicroconstituents in Luzhou-flavor liquor, and 178 kinds ofmicroconstitents in Fen-flavor liquor. The experiments proved that GCxGC/TOFMS was useful greatly in the analysis of microconstituents in liquor and in the research on liquor style formation mechanism.（Tran, by YUE Yang）
