摘 要:选择不同产地具有代表性的黄酒类型,采用气相色谱质谱联用法(GC-MS)分析黄酒中的挥发性成分,分析不同产地、不同酒型之间的差异,构建指纹图谱。通过主成分分析法建立共有模式,共筛选出17个共有峰,利用欧式距离算法进行相似度分析,显示3种不同类型的样品之间具有显著差异。再分别进行多元统计分析,建立样品分类识别模型。最后,通过聚类统计分析、神经网络分析,验证了该模型可以很好地将不同种类、不同产地的黄酒进行区分。The representative rice wine types from different origins were selected, the volatile components in rice wine were analyzed by gas chromatography-mass spectrometry, the differences between different origins and different wine types were analyzed, and the fingerprint was constructed.A common pattern was established by principal component analysis, and a total of 17 common peaks were screened out.Similarity analysis was carried out using the Euclidean distance algorithm, which showed that there were significant differences between the three different types of samples.Then multivariate statistical analysis was carried out to establish sample classification and recognition model.Finally, through HCA-heatmap analysis and self-organizing map clustering, the model was proved to be able to distinguish different types of Chinese rice wine from different origins.
