摘要
用GC-flash型电子鼻对3种香型(浓香、清香、酱香)白酒进行识别。结果表明,得到的PCA指纹图谱可以直观地看出3个香型酒分别分布在3个独立的区域,造成这种差别的主要因素是色谱图中的12个峰决定的第一主成分,在此实验研究中第一主成分的累积贡献率为99.436%。该方法可以作为进一步分析白酒香型之间的关系及新型香型划分的初步参考依据。
GC-flash type electronic nose was used to analyze liquor of three main flavor types （Luzhou-flavor, Fen-flavor and Maotai-flavor）. The obtained PCA fingerprint results indicated that the fingerprint of liquor of three main flavor types distributed in three independent areas and such difference caused by the first main components （determined by 12 peaks in the spectrum）. In the experimental study, it was found that the accumulative contributing efficiency of the first main component was 99.436 %. Besides, such method could be applied for further analysis of the relations among liquor of different flavor types and for the classification of liquor of new flavor types.
