摘要
为研究不同风格类型卷烟中性香味成分的差异性,采用同时蒸馏萃取法和气相色谱质谱联用技术对9种不同风格类型卷烟中性香味成分进行测定,并通过方差分析、主成分分析和聚类分析对4种类型香味成分进行分析。由方差分析结果可知,针对类胡萝卜素降解产物、棕色化反应产物、芳香族氨基酸裂解产物的总量在I风格卷烟之间没有显著性差异,并且I风格卷烟棕色化反应产物与其他品类卷烟均存在显著性差异;由主成分分析可知,4大类中性香味成分简化为5个主成分,通过计算中性香味成分在5个主成分上的权重,得出不同风格类型卷烟之间差异主要体现在氧化异佛尔酮、6-甲基-5-庚烯-2-醇、β-大马酮和苯乙醛的含量变化;由聚类分析可知,可将不同风格卷烟分为9类,相同风格卷烟能够被分为一类,不同风格卷烟分类效果良好,表明中性香味成分能够用来区分不同风格的卷烟,方法可以为中式卷烟品类构建以及风格特征剖析提供依据。
In order to understand the differences of neutral aroma components in different styles of cigarettes,the simultaneous distillation extraction and gas chromatography-mass spectrometry were used to determine the neutral flavor components in 9 different styles of cigarettes,and the four types of flavor components were analyzed by variance analysis,principal component analysis and cluster analysis.The results of analysis of variance showed that there was no significant difference between the total amount of carotenoid degradation products,browning reaction products and aromatic amino acid cleavage products in I-style cigarettes,and the browning reaction products of I-style cigarettes were significantly different from those of other categories of cigarettes.Based on the principal component analysis,the four major categories of neutral aroma components were simplified into five principal components.By calculating the weight of neutral flavor components on the five principal components,it was concluded that the differences between different styles of cigarettes were mainly reflected in the content changes of isophorone,6-methyl-5-hepten-2-ol,β-damascone and phenylacetaldehyde.Cluster analysis showed that different styles of cigarettes can be divided into 9 categories,and the same style of cigarettes can be divided into one category.The classification effect of different styles of cigarettes was good,which showed that neutral aroma components can be used to distinguish different styles of cigarettes.The method can provide a basis for the construction of Chinese cigarette categories and the analysis of style characteristics.
