接装纸透气度对不同规格卷烟感官质量和烟气化学成分的影响分析

为考察卷烟辅材接装纸透气度变化对不同规格卷烟感官质量和烟气化学成分的影响,以相同烟丝制备的不同接装纸透气度的常规、中支及细支卷烟为研究对象,对比分析了接装纸透气度变化对3种规格卷烟的物理指标、感官质量、烟气指标、烟气化学成分的影响差异.结果表明:1)接装纸透气度同卷烟吸阻呈线性负相关关系,同卷烟的总通风率呈线性正相关关系,影响程度均随烟支圆周的降低而变大;2)接装纸透气度对常规和中支的感官影响均比细支卷烟显著,随接装纸透气度增加,常规和中支的感官质量总分均呈明显下降趋势,但对于细支烟,感官质量总分呈先上升又略有下降的趋势;3)接装纸透气度与卷烟的单口焦油、单口CO及单口烟碱释放量均呈显著线性负相关关系.对单口焦油、单口CO的影响程度常规及中支大于细支卷烟,对单口烟碱的影响程度中支及细支大于常规卷烟;4)每克烟丝所释放的烟气化学成分,总量上由大到小为中支卷烟,细支卷烟,常规卷烟.其中,酮类、醛类质量分数细支明显高于常规及中支,酚类质量分数细支明显低于常规及中支,烯类、酯类、呋喃类及醇类质量分数细支与中支卷烟相当,高于常规,氮杂环类、酸类质量分数细支与常规相当,低于中支.

Effects of Air Permeability of Tipping Paper on Sensory Quality and Chemical Components of Smoke for Cigarettes with Different Sizes

In order to investigate the influences of air permeability of tipping paper on sensory quality and smoke chemical components of cigarettes with different sizes, normal, middle and slim cigarettes with tipping paper differing in air permeability and similar tobacco shred were prepared, and their physical indexes, sensory quality, routine smoke indexes and smoke chemical components were studied. The air permeability of tipping paper was shown to be in a negative linear correlation with draw resistance, and in a positive linear correlation with the total ventilation rate of the cigarette. The degree of influence increased with decreasing circumference of the cigarette. The air permeability of tipping paper had greater impact on sensory quality of normal and middle cigarettes than on that of slim cigarette. With the increase in air permeability of tipping paper, sensory quality grades of normal and middle cigarettes showed an obvious decreasing tendency, while for slim cigarette they first increased and then declined slightly. An obvious linear positive correlation was found to exist between air permeability of tipping paper and the content of a single mouth of tar, carbon monoxide and nicotine. The air permeability of tipping paper had greater influence on the contents of a single mouth of tar and carbon monoxide for normal and middle cigarettes. And the contents of a single mouth of nicotine for middle and slim cigarettes were more sensitive to the air permeability of tipping paper. The middle cigarette had the maximal release amount of chemical components of smoke for each gram of cut tobacco, followed successively by slim and normal cigarettes. The ketone and aldehydes amount of slim cigarette were obviously higher than those of normal and middle cigarettes, but the phenols amount of slim cigarette was much lower. And similar amount of alkenes, esters, furans and alcohols for slim and middle cigarettes were detected. Nitric heterocycles and acids contents of slim and normal cigarettes showed similar concentrations, which were lower than those of middle cigarette.
