细支卷烟密端增量对产品质量及抽吸感受的影响OA

To enhance the smoking experience of slim cigarettes and to clarify the control goal for filter cigarette making process,slim cigarettes with a length of 97.0 mm and a circumference of 17.0 mm were studied,and the variations in physical indexes,dynamic draw resistance,combustion cone-falling propensity,mainstream smoke chemical composition and sensory quality among the cigarettes with different dense-end ratios.The results indicated that:1)With an increase in the dense-end ratio,the average hardness of cigarette samples in each group decreased.Cigarette samples with dense-end ratio of 7%-15%(group B and group C)showed better stability of all physical indexes.2)Cigarette samples with dense-end ratio higher than 15%(group D and group E)had significantly higher dynamic draw resistance for the second puff compared with the other cigarettes.The average dynamic draw resistance increased by roughly 15 Pa with a 10 mg/cm³ rise in cut tobacco density for a single puff.3)Cigarette samples with dense-end ratio less than 7%(group A)had the highest combustion cone-falling propensity(36%),while those with higher dense-end ratio were more prone to combustion cone fall in the middle stage of smoking(3rd-5th puffs).4)No significant differences were found in smoke chemical composition among cigarettes with different dense-end ratios,while their puff-by-puff release patterns varied.For samples with dense-end ratio more than 20%(group E),over 40 chemical components in the first two puffs differed significantly from those with low dense-end ratio(group B).5)From the perspective of smoking smoothness,there were significant differences between cigarettes with dense-end ratio more than 20%and cigarettes with small and moderate dense-end ratios(7%-15%).This study provides methodological and data support for optimizing the control of filter cigarette making processes and enhancing the smoking smoothness of slim cigarettes.
