【摘要】 【目的】研究不同风格卷烟碱性香味成分差异性。【方法】采用同时蒸馏萃取法以及气相色谱质谱联用技术对13种不同风格类型卷烟碱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12种碱性香味成分进行分析。【结果】①由方差分析结果可知,针对吡啶、2,5-二甲基吡嗪、3-乙基吡啶和碱性香味成分总量,M品类卷烟间无显著性差异;针对2-甲基吡嗪、3-甲基吡啶、2,6-二甲基吡啶、2,5-二甲基吡嗪、2,3-二甲基吡嗪、2,5-二甲基吡啶、2-甲基喹啉,M品类卷烟与大多数其他品类卷烟间存在显著性差异;②由主成分分析结果可知,12种碱性香味成分可简化为4个主成分,得出不同风格类型卷烟之间差异主要体现在吡啶、2-甲基吡嗪、3-甲基吡啶、3-乙基吡啶、喹啉、3-苯基吡啶的含量变化;③由聚类分析结果可知,可将不同风格卷烟分为8类,同品类卷烟能够被分为一类,不同风格卷烟分类效果良好,聚类分析与主成分分析结果基本吻合,表明碱性香味成分能够用来区分不同风格的卷烟。【结论】为研究不同风格类型卷烟的差异性,为中式卷烟品类构建以及风格特征剖析提供依据。更多还原

【Abstract】 【Objective】The present paper aimed to study the differences in the basic aroma components of different styles of cigarettes. 【Method】 The alkaline flavor components of 13 different styles of cigarettes were determined by simultaneous distillation extraction and gas chromatography-mass spectrometry. The analysis of 12 basic aroma components was carried out by analysis of variance, principal component analysis and cluster analysis.【Result】(i)From the results of analysis of variance, it was found that there was no significant difference between M-type cigarettes for the total amount of pyridine, 2,5-dimethylpyrazine, 3-ethylpyridine and basic aroma components; Pyrazine, 3-methylpyridine, 2,6-lutidine, 2,5-dimethylpyrazine, 2,3-dimethylpyrazine, 2,5-lutidine, 2-methyl Quinoquinoline, M-type cigarettes and most other types of cigarettes have significant differences;(ii)From the results of principal component analysis, 12 basic aroma components can be simplified into four main components, resulting in differences between different styles of cigarettes Mainly reflected in the content of pyridine, 2-methylpyrazine, 3-methylpyridine, 3-ethylpyridine, quinoline, 3-phenylpyridine;(iii)From the results of cluster analysis, it can be divided into different styles of cigarettes for 8 categories, the same category of cigarettes can be divided into one category, the classification of different styles of cigarettes is good, the results of cluster analysis are basically consistent with the results of principal component analysis, indicating that alkaline flavor components can be used to distinguish different styles of cigarettes.【Conclusion】In order to study the differences of cigarettes of different styles, it provides a basis for the construction of Chinese cigarettes and the analysis of style characteristics.更多还原
