摘　　要：【目的】缓解目前细支加热卷烟存在的抽吸时前后感官差异较大、易挥发特征香持续性较差、主要成分逐口释放变化较大等问题。【方法】将器具的周向加热温度降至200℃以下,并进行雾化剂的选择,考察羰基化合物释放情况、雾化剂对烟气释放均匀性的影响以及感官评吸情况。【结果】(1)对于细支加热卷烟而言,在150℃~200℃加热时,比较适宜的雾化剂是1,2-丙二醇和1,3-丁二醇。(2)随着平均加热温度从220℃降低至170℃,烟气中低分子量挥发性羰基化合物释放量明显降低,其中甲醛降低幅度达到81%。(3)降低加热温度和选用适宜的雾化剂,有利于提高烟气释放均匀性,同时满足烟雾量中等、化学气息弱、烟气释放均匀性较好的雾化剂组合为1,2-丙二醇、1,3-丁二醇和丙三醇,三者比例为1∶1∶1。【结论】虽然加热温度降低会使烟草香气成分释放减少,但是香气均匀性和持续性都有所改善。[Background]This study aims to alleviate the problems existing in slim heated cigarettes,such as significant sensory differences during smoking,poor persistence of volatile characteristic flavors,and considerable variation in the release of main components from puff to puff.[Methods]The circumferential heating temperature of the device was reduced to below 200℃,and atomizing agents were selected for evaluation.The release of carbonyl compounds,the impact of atomizing agents on the uniformity of smoke release,and sensory assessment were examined.[Results]Test data show:1)For the slim heated cigarettes,when heated at 150-200℃,the suitable atomizing agents are 1,2-propylene glycol and 1,3-butanediol.2)As the average heating temperature decreased from 220℃ to 170℃,the content of low-molecular-weight volatile carbonyls decreased significantly,with formaldehyde decreasing by up to 81%.3)Reducing the heating temperature and selecting suitable atomizing agents are beneficial to improving the uniformity of aerosol release.Meanwhile,the combination of atomizing agents that meets the requirements of moderate smoke volume,weak chemical smell,and good uniformity includes 1,2-propylene glycol,1,3-butanediol,and glycerol in a ratio of 1∶1∶1.[Conclusion]Although reducing the heating temperature may lead to a decrease in the release of tobacco aroma components,the uniformity and persistence of the aroma are improved.
