摘　　要：为探索卷烟烟气中彰显香气风格的关键中性香气成分,采用烟用香料作用阈值感官评价方法,评定了32种重要中性香气成分(中性成分)的作用阈值,同时以GC-MS技术测定了其在卷烟烟气中的释放量,获得活性阈值并进行数据分析。结果表明:(1)32种中性成分的作用阈值介于7.04×10^(-14)和6.76×10^(-7)μg/支之间,戊酸乙酯和β-二氢大马酮的作用阈值最小,糠酸甲酯等6种中性成分的作用阈值较大,作用阈值最高相差约7个数量级。(2)主流烟气中32种中性成分的总质量分数为11.320μg/支;其中,5-甲基糠醛的质量分数最高(5.881μg/支),占总量的52.0%;β-大马酮和苯乙醇的质量分数较高,其值之和占总量的14.5%。(3)32种中性成分的活性阈值范围为2.45×10~4~2.77×10^(12),总活性阈值为6.38×10^(12);戊酸乙酯等7种中性成分活性阈值之和占总活性阈值的96.5%,表明在彰显卷烟香气风格时此7种成分作为关键香气成分起着决定性作用。In order to investigate important neutral aroma components in mainstream cigarette smoke that play decisive roles in demonstrating the aroma style of cigarettes, the functional thresholds of 32 key neutral aroma components were sensorilly evaluated by the method of functional thresholds for tobacco flavors, and their releases in mainstream cigarette smoke were determined by GC-MS. The activity thresholds of the 32 components were obtained and analyzed. The results showed that： 1） The functional thresholds of the 32 components ranged from 7.04× 10-14 to 6.76× 10-7 μg.cig-1; those of ethyl valerate and β-damascone were the lowest, while those of six neutral components, such as methyl 2-furoate, were higher. The maximum difference of functional thresholds among the 32 components covered about seven orders of magnitude. 2） The total content of 32 neutral components in mainstream cigarette smoke was 11.320 μg.cig-1. The content of 5-methylfurfural was the highest （5.881 μg.cig-1）,which accounted for 52.0% of the total content. The contents of β-damascenone and phenethyl alcohol were relatively higher, and the sum of their contents accounted for 14.5% of the total content. 3） The activity thresholds of the 32 components ranged from 2.45×10^4 to 2.77×10^12, which was 6.38 × 10^12 in total. The sum of activity thresholds of seven components, such as ethyl valerate,accounted for 96.5% of the total activity thresholds, which indicates that the above seven neutral components played decisive roles in demonstrating the aroma style of cigarette.
