晒红烟重要致香物质与其感官质量的相关性研究

为研究晒红烟中致香物质含量与感官评吸质量的相关关系,采用简单相关分析和典型相关分析对我国四川、吉林、江西、湖南、贵州、浙江、山东和黑龙江8个产区晒红烟烟叶中重要致香物质与感官评吸指标香气质、香气量、余味、杂气、刺激性和总得分的关系进行了研究。结果表明,与感官评吸质量关系较密切的致香物质有22种,其中β-大马酮、3-羟基-二氢大马酮、3-甲基巴豆醛、戊醇、异戊醇、糠醛、2-乙酰基呋喃、2-正戊基呋喃、2-甲基四氢呋喃-3-酮、5-甲基糠醛、茄酮、藏红花醛、吲哚、γ-丁内酯、吡咯、降茄二酮和1,3,7,7-四甲基-2-氧双环4.4.0]癸-9-酮对感官评吸质量有正面效应,异佛尔酮、苯甲醛、苯乙醛、叶绿醇-2、3-乙酰吡啶、2-甲基-2-庚烯-6-酮和2-乙基吡啶对感官评吸质量有负面效应。

Correlation Analysis on Important Aroma Components and Smoking Quality of Red Sun-cured Tobacco

Simple correlation analysis and canonical correlation analysis were used to analyze the relationship between important aroma components and aroma quality, aroma quantity, aftertaste, mixed gas, irritancy and total score of smoking quality in red suncured tobacco leaves from in Sichuan, Jilin, Jiangxi, Hunan, Guizhou, Zhejiang, Shandong, and Heilongjiang. The results showed that 22 aroma components were closely related to smoking quality, among which β-damascenone, 3-hydroxy-2-damascenone, 3-methyl crotonaldehyde, amyl alcohol, isoamyl alcohol, furfural, 2-acetyl furan, 2-pentyl furan, 2-methyltetrahydrofuran-3-one, 5-methyl furfural, solanone, safranal, indole, gamma butyrolactone , pyrrole, norsolandion and 1,3,7,7-four methyl-2-oxygen double ring 4.4.0] decyl-9-one had a positive effect while isophorone, benzaldehyde, benzene acetaldehyde, phytol-2, 3-acetyl pyridine,2-methyl-2-hepten-6-one and 2-ethylpyridine had a negative effect on smoking quality.
