摘　　要：为考察硃砂烟在热解条件下释放气体产物的特性以及对卷烟抽吸感官品质的影响,采用有氧热解与气相色谱-质谱仪(GC-MS)联用分析的方法,模拟烟草抽吸热环境,对烟草热解气体产物的组成和特性进行对比分析。烟草样品分别采用云南省曲靖K326、保山红大品种、大理红大和曲靖云烟97硃砂烟为烟草样品原料,通过烟气捕获、香气成分准确分离分析,建立烟草感官贡献度计算方法及神经网络模型,对烟草进行了感官预测评价。结果表明:与普通烟叶相比,硃砂烟热解得到的气体产物中香气成分占比较高;考察感官特征化合物,硃砂烟含杂气属性化合物少且感官贡献度小。同时预测模型评价及评吸实验表明,硃砂烟的香气质、香气量、吃味等指标得分相对较高,可见硃砂烟总体评吸质量优于普通烟草,模型预测结果与评吸实验结果一致。In order to investigate the characteristics of the gas products released by cherry-red tobacco under precise pyrolysis conditions and the influence on the sensory quality of cigarette smoking,the method of aerobic pyrolysis combined with GC-MS was used to simulate the actual tobacco smoking heat absorption environment,and the composition and characteristics of tobacco pyrolytic gas products were analyzed.Tobacco samples were taken from Yunnan Qujing K326,Baoshan Hongda variety,Dali hongda and cherry-red tobacco as tobacco sample raw materials.Through accurate flue gas capture,accurate separation of flue gas compounds,the sensory contribution calculation method and neural network model were established to predict the sensory contribution of tobacco.The results show that the aroma components of the gas products from the pyrolysis of cherry-red tobacco are relatively high compared with the common tobacco.The sensory characteristic compounds of cherry-red tobacco are less and accounted for less percentage of smoke.Meanwhile,the evaluation of prediction model and smoking test showed that the score of cherry-red tobacco flavor,aroma quantity,impurity gas and taste was relatively high.It can be seen that the overall quality of cherry-red tobacco was better than that of ordinary tobacco.And the calculation results of model prediction was basically consistent with the results of smoking evaluation experiment.
