卷烟主要化学成分与感官质量相关性分析

为研究卷烟化学成分及其比例对卷烟感官质量(评吸结果)的影响,对四川中烟主要品牌的卷烟进行样本抽取并测定水溶性总糖、总氮、烟碱、钾、氯等主要化学成分含量,并计算糖碱比、糖氮比、钾氯比等相关化学指标,同时进行感官质量评价,对卷烟的化学指标和感官评吸指标进行相关分析和回归分析,研究化学指标与感官质量之间的相互关系。结果表明:卷烟感官评吸指标中的香气、杂气、刺激性、余味均与糖氮比、糖碱比、总糖呈极显著正相关,但与氯、钾、总氮呈极显著负相关;对卷烟感官质量(香气、杂气、刺激性、余味)影响较大的化学指标依次为:糖氮比总糖糖碱比钾氯总氮;逐步回归分析结果表明:卷烟的糖氮比对卷烟香气、刺激性、余味的变化有显著影响,总糖对杂气的变化有显著影响。

Analysis on the Correlation between Major Chemical Elements andSensory Qualities of Cigarettes

: To study the effect of chemical composition and proportion on smoking sensory quality of cigarettes, major brands of cigarettes in China Tobacco Sichuan Industrial Company were sampled to determine their major chemical elements and the sensory qualities. Correlation analysis and regression analysis were conducted on the chemical indexes and sensory evaluation indexes of cigarettes. The results showed that the aroma, impurities, irritation and aftertaste of cigarette sensory evaluation indicators were positively correlated with sugar-nitrogen ratio, sugar-nicotine ratio and total sugar, and negatively correlated with chlorine, potassium and total nitrogen. The chemical indexes affecting the sensory qualities of cigarettes (aroma, impurities, irritation and aftertaste) are: sugar-nitrogen ratio > total sugar > sugar-nicotine ratio > potassium > chlorine > total nitrogen. Stepwise regression analysis showed that the sugar-nitrogen ratio of cigarettes had a significant effect on the changes of cigarette aroma, irritation and aftertaste, and the total sugar had a significant effect on the changes of impurities.
