水松纸透气度对中支卷烟主流烟气及燃烧温度的影响

Effect of Tipping Paper Air Permeability on Mainstream Smoke and Combustion Temperature of Medium Cigarette

以不同透气度水松纸的中支卷烟为研究对象,分析测试了卷烟主流烟气成分,并采用红外热像仪测定了卷烟的燃烧温度。结果表明:随着水松纸透气度增大,中支卷烟主流烟气中总粒相物、水分、焦油、烟碱和CO质量均呈显著下降趋势,抽吸口数呈增加趋势;单口总粒相物、水分、焦油以及CO释放量直线降低,单口烟碱释放量基本没有变化。感官质量方面,随着水松纸透气度的增加,烟气特性均呈下降趋势,吃味特性则先上升后下降,香气和谐调性下降较明显,杂气呈先上升后下降趋势。中支卷烟抽吸最高温度、最高温平均温度、抽吸平均温度以及峰值平均值等随着水松纸透气度的增加均呈下降趋势,阴燃平均温度未发生明显变化。水松纸透气度变化造成卷烟滤嘴通风发生改变,不仅稀释了主流烟气指标,同时滤嘴通风度的增加抑制了烟丝的充分燃烧,从而导致燃烧温度降低。在保证整体香气特性、烟气特性的前提下,可适当提高水松纸的透气度来降低部分杂气和刺激性,从而提升整体抽吸舒适性。

In order to study the effect of tipping paper air permeability on medium cigarettes,the mainstream smoke components were analyzed and the combustion temperature parameters of cigarettes were tested with infrared thermal imager.The results showed that with the increase of tipping paper air permeability,the content of mainstream smoke components including TPM(total particulate matter),water,tar,nicotine and CO decreased,but puff increased.Good linear relationships between air permeability and per mouth release of TPM,water,tar and CO were obtained,and the per mouth release of nicotine hardly changed.With the increase of air permeability on tipping paper,the sensory quality of smoke characteristics decreased and the taste characteristics first increased and then decreased.In terms of aroma characteristics,with the increase of air permeability,the aroma and harmonization decreased obviously and the offensive taste first increased and then decreased.With the increase of tipping paper air permeability,the highest burning temperature,average value of the highest burning temperature,average burning temperature and average peak value of the temperatures decreased,and the average smoldering temperature remained unchanged.The ventilation of cigarette filter was changed with the air permeability of tipping paper,which not only diluted the mainstream smoke,but also reduced the combustion temperature of tobacco.Maintaining the overall aroma characteristics and smoke characteristics,the air permeability of tipping paper can be improved to reduce part of the offensive taste and irritancy so as to improve smoking amenity.
