摘　　要：为探究不同滤嘴设计的卷烟爆珠单体香料成分的释放行为,分析了爆珠添加位置和滤嘴打孔情况对40种代表性单体香料成分在卷烟主流烟气中的迁移率和逐口释放量的影响。结果表明:①在迁移率方面,爆珠添加位置和滤嘴打孔情况对香味成分的释放影响显著。单体香料成分的迁移率爆珠位置在6 mm(距嘴端)处时大于18 mm处,不打孔滤嘴大于打孔滤嘴。对醇类、酮类和酯类中属于同系物的单体香料成分来说,同一成分爆珠添加位置在6 mm处情况下的迁移率与在18 mm处迁移率的比值随分子质量数的变化趋势不同;同一成分在不打孔滤嘴情况下的迁移率与打孔滤嘴迁移率的比值随分子质量数的变化趋势一致,且随分子质量数的增加而减小。②在单体香料成分逐口释放量及单位TPM逐口释放量方面,爆珠添加于6 mm处时均大于18 mm处;不打孔滤嘴单体香料成分逐口释放量大于打孔滤嘴,而打孔滤嘴单位TPM逐口释放量大于不打孔滤嘴。③沸点较低的香味成分,如己酸乙酯、庚酸乙酯、2-庚酮、2-辛酮和正戊醇等,在逐口抽吸至第4口和第5口时的释放量增幅较明显。In order to investigate the influences of cigarette filter design on the release of monomer flavor components in breakable capsules,the effects of capsule location in filter and filter ventilation on the transfer rates and puff-by-puff releases of 40 representative monomer flavor components in mainstream cigarette smoke were analyzed.The results showed that:1)Capsule location in filter and filter ventilation levels significantly affected the transfer rates of the aroma components.The transfer rates of the monomer aroma components were higher when the capsule was planted at 6 mm to the mouth end as compared to those at 18 mm,or when the filter was unventilated.With the increase of the molecular weight of flavor compound,the transfer rate ratios between the capsule planted at 6 mm and that at 18 mm of the same component in alcohol,ketone and ester homologues presented different variation trends.The transfer rate ratios when the filter was unventilated to that of ventilated of the same component in these homologues deceased.2)The puff-by-puff releases and the puff-by-puff releases per unit TPM of monomer aroma components were higher when the capsule was planted at 6 mm than at 18 mm.The puff-by-puff releases were higher and the puff-by-puff releases per unit TPM were lower when the filter was unventilated than ventilated.3)The releases of those aroma components with a lower boiling point,such as ethyl hexanoate,ethyl heptanoate,2-heptanone,2-octanone and 1-pentanol,increased significantly at the fourth and fifth puffs.
