摘　　要：为研究不同回潮区温度对卷烟清香风格特征的影响,采用GC-MS/MS对50种国内市售成品卷烟烟丝中30种致香成分进行分析建模,以得到能够表征清香风格特征的模型,并根据该模型对3种回潮温度下的烟丝样品的清香风格特征的感官品质进行定量分析。研究发现:在30种致香成分中,23种进入回归方程,方程的决定系数为0.942,调整决定系数为0.932,该方程对于多种卷烟的清香风格特征具有良好的拟合效果。X7~X16这10种物质与清香评分呈现正相关,其中γ-十一内酯与清香评分呈现最大正相关;其余13种物质与清香评分呈现负相关,其中δ-十一内酯与清香评分呈现最大负相关。模型对测试集清香评吸指标具有较好的拟合效果,预测值与实际值误差较小,MAE值(平均绝对误差)为0.1007分。随着回潮区温度的升高,烟丝中的致香成分含量均有相应的降低,烟丝的致香成分数目也有降低。根据卷烟烟丝中的30种致香成分含量进行分析建模,建立清香风格特征感官品质与致香成分含量的联系,得到的回归模型预测的卷烟清香风格特征感官评吸得分与实际评吸结果吻合度较高,对于清香这一感官品质指标具有较好的预测能力。根据建立的模型研究回潮区温度对卷烟感官品质的影响,回潮区温度控制在50℃时更有利于得到感官评分更高的烟丝。To study the influence of different temperature of the regain zone on the characteristics of fen-flavour style tobacoo,30 aroma components in 50 kinds of domestic commercial cut tobacco were analyzed and modeled by GC-MS/MS,so as to obtain a model that can characterize the fragrance characteristics.According to the model,the sensory quality of cut tobacco samples at 3 different moisture regain temperatures was quantitatively analyzed.The results showed that:among the 30 aroma components,23 was selected into the regression equation,the determination coefficient of the equation is 0.942,and the adjustment coefficient is 0.932,indicating the good fitting effect of the regression equation.The 10 substances of X7 to X16 were positively correlated with the scent score,and theγ-undecalactone was the most positively correlated with the scent score.The other 13 substances were negatively correlated with the scent score,andδ-undecalactone was the most negatively correlated with the scent score.The model has a good fitting effect on the scent evaluation index of the test set.The error between the predicted value and the actual value is small,and the MAE value(average absolute error)is 0.1007 points.With the increase of temperature in the moisture regain zone,the content of aroma components in cut tobacco has decreased accordingly,and the number of aroma components in cut tobacco has also decreased.Based on the analysis and modeling of 30 kinds of aroma components in cigarette tobacco,the relationship between sensory quality of fen-flavor style characteristics and content of aroma components was established.The results of regression model predicted that the sensory evaluation score of cigarette fen-flavor style characteristics was consistent with the actual results,which had a good prediction ability for the sensory quality index of fragrance clearing.According to the model,the influence of the resurgence temperature on the sensory quality of cigarette was studied.The 50℃of temperature was controlled more favorable to ge
