摘要
[目的]分析 2017 年来国产细支卷烟质量的总体变化,描述中式细支卷烟的质量特征.[方法]对 2017 年和2021 年国产重点细支卷烟牌号的烟丝形态、物理指标和与吸用有关的指标值及加工稳定性进行对比、分析.[结果]与 2017 年相比,2021 年国产细支卷烟:(1)烟丝宽度有所增加,烟丝特征尺寸略有减小,烟丝尺寸分布更趋集中;(2)单支质量、长度、圆周、封闭吸阻变化不明显,硬度、烟支密度增大,滤嘴通风率和总通风率减小,单支质量、长度、圆周、开放吸阻、滤嘴通风率、总通风率的稳定性提升,烟支密度分布一致性更好;(3)动态吸阻平均值变化不明显,烟支轴向动态吸阻稳定性明显提高,但动态吸阻分布一致性稍变差,燃烧锥落头倾向明显降低.[结论]"控长、控碎、控宽"等应用技术进步推动了行业细支卷烟升级创新,关键物理指标、燃吸性能指标等稳定性提升,综合品质更适合中国消费者的吸食习惯.
Abstract
[objective]This study aims to analyze the overall changes in the quality of domestic slim cigarettes since 2017 and to describe the quality characteristics of Chinese-style slim cigarettes.[Methods]A comparison and analysis were conducted on the tobacco morphology,physical indices,and smoking-related indices,as well as processing stability,of key domestic slim cigarette brands between 2017 and 2021.[Results]Compared to 2017,in 2021,domestic slim cigarettes:(1)showed an increase in tobacco width,a slight decrease in characteristic dimensions of the tobacco,and a more concentrated distribution of tobacco dimensions;(2)had no significant changes in single stick weight,length,circumference,and closed draw resistance,but increased hardness and cigarette density,reduced filter ventilation rate and total ventilation rate,improved stability of single stick weight,length,circumference,open draw resistance,filter ventilation rate,total ventilation rate,and better uniformity in cigarette density distribution;(3)had no significant changes in the average dynamic resistance,significantly improved stability in axial dynamic resistance of cigarettes,though uniformity in dynamic resistance distribution worsened slightly,and a clear reduction in the falling tendency of the combustion cone.[Conclusion]Technological advancements in"controlling length,fragmentation,and width"have driven the industry's upgrade and innovation of slim cigarettes.The stability of key physical indices and smoking performance indices has improved,and the overall quality is more suited to the smoking habits of Chinese consumers.
