细支和常规卷烟主流烟气常规成分和5种关键烤甜香味成分逐口释放量的差异分析

建立了测定5种烤甜香味成分逐口释放量的分析方法，采用相同烟丝配方卷制细支和常规卷烟，考察细支和常规卷烟主流烟气常规与5种关键烤甜香味成分逐口释放量差异。结果表明:①分析方法重复性、灵敏度和准确度较好，适合于卷烟逐口烟气中5种烤甜香味成分的定量分析；②细支卷烟常规成分逐口释放量均低于常规卷烟，总粒相物（TPM）、焦油、水分的逐口释放变化幅度大于常规卷烟，烟碱变化幅度小于常规卷烟；③细支卷烟糠醇、5-甲基糠醛和3-甲基-2-环戊烯-1-酮的逐口释放量高于常规卷烟（除第1口外），4-羟基-2，5-二甲基-3（2H）呋喃酮（呋喃酮）和麦芽酚的逐口释放量略低于常规卷烟；抽吸中段细支卷烟糠醇和5-甲基糠醛的逐口释放稳定性优于常规卷烟，3-甲基-2-环戊烯-1-酮劣于常规卷烟，呋喃酮和麦芽酚差异不大；细支卷烟5种香味成分总量中糠醇和5-甲基糠醛所占比例高于常规卷烟，3-甲基-2-环戊烯-1-酮、呋喃酮和麦芽酚低于常规卷烟。 

Differential analysis of puff-by-puff deliveries of routine chemical analyses and five key roasted sweet aroma components in mainstream smoke of slim cigarettes and normal cigarettes

Slim cigarettes and normal cigarettes are rolled with same blend.In this work, a method was developed to determine puff-bypuff deliveries of five roasted sweet aroma components.The difference of puff-by-puff deliveries of routine chemical components and five roasted sweet aroma components in mainstream smoke of slim cigarettes and normal cigarettes were investigated.Results showed that: ①This method featured good repeatability, sensitivity and accuracy, and is suitable for the analysis of puff-by-puff deliveries of five roasted sweet aroma components in cigarettes smoke.②Puff-by-puff deliveries of TPM, tar and nicotine of slim cigarettes were lower than that of normal cigarettes.The puff-by-puff deliveries range of TPM, tar and water of slim cigarettes was larger than that of normal cigarettes.The puff-by-puff deliveries range of nicotine was smaller than that of normal cigarettes.③Puff-by-puff deliveries of furfuryl alcohol, 5-methyl furfural, and 3-methyl-2-cyclopenten-1-one of slim cigarettes were higher than that of normal cigarettes (except for the first puff), while the puff-by-puff deliveries of furaneol and maltol were slightly lower than that of normal cigarettes.In middle puff, the puff-by-puff release stability of furfuryl alcohol and 5-methyl furfural of slim cigarettes was better than that of normal cigarettes, and the puff-by-puff release stability of 3-methyl-2-cyclopenten-1-one was worse that of normal cigarettes.There were no significant difference in puff-by-puff release stability of furaneol and maltol between slim cigarettes and normal cigarettes.The proportion of furfuryl alcohol and 5-methyl furfural of slim cigarettes was higher than that of normal cigarettes, while the proportion of 3-methyl-2-cyclopenten-1-one, furaneol and maltol of slim cigarettes was lower than that of normal cigarettes.
