【摘要】为比较电加热卷烟和传统卷烟中的凉味剂在转移率方面的差异,采用气相色谱质谱法(GC-MS)分别测定了两种类型卷烟(各9个样品)烟丝/再造烟叶中9种凉味剂(L-薄荷酮、异薄荷酮、异胡薄荷醇、DL-薄荷醇、乙酸薄荷酯、乳酸薄荷酯、WS-3、WS-5和WS-23)的含量及其主流烟气释放量,计算了7种凉味剂的烟气转移率。结果表明:①该方法精密度较好,回收率较高,适用于烟草材料及卷烟烟气中9种凉味剂的检测。②传统卷烟中凉味剂的含量为0.07~8.81 mg/g,转移率为3.80%~49.12%;电加热卷烟中凉味剂的含量为0.14~14.37 mg/g,转移率为4.68%~42.53%。③对于传统卷烟,凉味剂转移率与烟气总粒相物中凉味剂的释放量无显著相关关系,但对于电加热卷烟,凉味剂转移率随添加量的减少呈递增趋势。④两类卷烟烟气总粒相物中DL-薄荷醇释放量为0.11~1.28 mg/支,转移率为5.68%~49.12%,其余6种凉味剂释放量为0.01~0.19 mg/支,转移率为3.80%~41.67%;总体上,乙酸薄荷酯、L-薄荷酮和异胡薄荷醇转移率高于乳酸薄荷酯、WS-3和WS-23。

【Abstract】In order to compare the transfer rates of cooling agents between electrically heated cigarettes and conventional combustible cigarettes, we adopted the gas chromatography-mass spectrometry (GC-MS) method to determine the content of nine cooling agents (L-menthone, isomenthone, isopregol, DL-menthol, menthyl acetate, menthyl lactate, WS-3, WS-5, and WS-23) in cut tobacco/reconstituted tobacco and mainstream smoke of nine electrically heated cigarette samples and nine conventional cigarette samples, and the transfer rates of seven cooling agents were calculated. The results are as follows. ① This method had high precision and recovery, which can be used for determining the content of nine cooling agents in tobacco materials and their transfer in cigarette smoke. ② For the conventional combustible cigarettes, the content of cooling agents was 0.07–8.81 mg/g and the transfer rates were 3.80%–49.12%. For the electrically heated cigarettes, the content of cooling agents was 0.14–14.37 mg/g and the transfer rates were 4.68%–42.53%. ③ For the traditional cigarettes, the transfer rates of cooling agents had no significant relationship with the release of cooling agents in total particulate matter (TPM) of mainstream smoke. However, for the electrically heated cigarettes, the transfer rates increased with the decrease of cooling agent addition rate. ④ In the TPM of mainstream smoke of all the samples, the release of DL-menthol ranged from 0.11 to 1.28 mg/cigarette and the transfer rates were 5.68%–49.12%; the releases of the other six cooling agents were in the range of 0.01–0.19 mg/cigarette and the transfer rates were 3.80%– 41.67%. In general, the transfer rates of menthyl acetate, L-menthone, and isopregol were higher than those of menthyl lactate, WS-3, and WS-23.
