Abstract：[Objective]This study aims to investigate the differences in sensory styles and their formation mechanisms among three medium-sized cigarettes.[Methods]Thermal desorption(TDU)coupled with comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry(GC×GC-TOFMS)was used to detect the volatile aroma compounds in the tobacco cuts of three medium-sized cigarettes.Combined with sensory evaluation,orthogonal partial least squares discriminant analysis(OPLS-DA)and partial least squares regression(PLSR),this study comparatively analyzed the formation mechanisms of aroma style differences among the three medium-sized cigarettes.[Results]The three medium-sized cigarettes have different aroma profiles.,the NX sample features prominent sweet and herbal notes,the LT sample is characterized by distinct fruity notes,and the SD sample highlights fresh and clean notes.A total of 102 volatile aroma compounds were detected in the three medium-sized cigarettes,among which 29 characteristic key aroma compounds had potential effects on the formation of differences in cigarette aroma styles.PLSR analysis revealed that these 29 aroma compounds were respectively correlated with different aroma style characteristics of cigarettes,and the differences in their contents might be the reason for the differences in aroma styles among the three cigarettes.[Conclusion]This study enriches the flavor analysis method and research findings of medium-sized cigarettes and provide a reference for the regulation of aroma styles in medium-sized cigarettes.
