摘要
为了解苔香型卷烟主流烟气中特征香味成分的逐口递送规律,分别选取17、20和24 mm 3个圆周的成品卷烟,并对烟支进行简单改造,考察了不同样品中2,4-二羟基-3,6-二甲基苯甲酸甲酯、2,4-二羟基-6-甲基苯甲酸乙酯、2-羟基-4-甲氧基-6-丙基苯甲酸乙酯和十六酸乙酯4种树苔成分的释放行为。结果表明:(1)总体而言,圆周17 mm烟支的逐口释放量先升后降,圆周20 mm烟支在第3口后趋于平稳,圆周24 mm烟支则随着逐口抽吸序号持续增加;(2)4种酯类特征成分的性质不同,因此其释放行为有所区别;(3)以单位焦油和单位烟碱计,不同圆周卷烟树苔成分的释放量均随逐口抽吸序号的增加和滤嘴通风的增大而减少,该变化趋势在17 mm卷烟中表现尤为明显;(4)降低吸阻可一定程度上改善酯类特征成分释放的均匀性。
In order to investigate the delivery pattern of characteristic treemoss aroma components in mainstream smoke of cigarette,cigarettes of three different circumferences(17,20 and 24 mm) were sampled.The release behaviors of four characteristic treemoss components,methyl 2,4-dihydroxy-3,6-dimethylbenzoate,ethyl 2,4-dihydroxy-6-methylbenzoate,ethyl 2-hydroxy-4-methoxy-6-propylbenzoate and ethyl hexadecanoate were investigated.The results showed that: 1) Generally,the puff-by-puff releases increased initially and then decreased for the cigarette of 17 mm circumference; while for the cigarette of 20 mm circumference,the puffby-puff releases was stable after the 3 rd puff,and for the cigarette of 24 mm circumference the yield increased continuously with the puff number.2) The different release patterns of the four characteristic ester compounds were mainly due to their different intrinsic properties.3) On per unit tar and per unit nicotine basis,the releases of treemoss aroma components in cigarette smoke of different circumferences decreased with the proceeding puffing and the increase of filter ventilation rate,especially the cigarette of 17 mm circumference.4) The releases of the characteristic ester components became more uniform to a certain extent by reducing the pressure drop of cigarette.
