烤烟主要烟气化学成分对卷烟感官舒适度的影响研究

 为研究烤烟烟气主要化学成分对卷烟感官舒适度的具体影响程度,并分析影响感官舒适度的关键化学成分.对50个涵盖国内主要烟叶产区及主要进口烤烟进行了42个烟气化学成分检测和较全面地感官舒适度评价,采用逐步回归方法建立了烟气化学成分对卷烟感官舒适度指标影响的统计模型.研究结果表明:建立的模型统计上高度显著(p_F<0.01),模型对感官舒适度具有较强的解释能力;各模型中所有自变量回归系数统计上均显著(p<0.05),模型中所有自变量对感官舒适度均有重要影响;建立的模型对感官舒适度具有较好的预测性能,可为卷烟产品研发及维护提供科学依据.

Effects of main smoke chemicals on sensory coziness in flue-cured tobacco

To study the specific effects of the main chemicals in cigarette smoke on sensory coziness and determine the key factors.42 smoke chemicals in 50 domestic and imported representative tobacco leaves were analyzed.Meanwhile,a comprehensive sensory coziness evaluation was conducted on the 50 samples.Statistical models for the effects of smoke chemicals on sensory coziness were obtained by stepwise regression method.The results showed that the obtained models were statistically highly significant(pF<0.01),namely the models can explain the sensory coziness very well.All the independent variables in the models were statistically significant(p<0.05),which signals that all the variables in the models were important for sensory coziness.The obtained models perform satisfactorily in the prediction for test samples,which indicates that the models can be reliably used to predict sensory coziness.The models could provide a scientific foundation for the development and maintenance of tobacco products.
