Abstract:A method for simultaneous determination of 112 aroma components in heated cigarette aerosols was established by ultrasonic extraction combined with GC-MS/MS quantitative detection. The aroma components in typical heated cigarette aerosols were compared. The results showed that: The linear correlation coefficients of 112 aroma compounds were all greater than 0.99. The detection limits of the method were 0.005~0.160 mg/L, the recoveries were 75.2%~128.0%, and the precision was less than 8.9%. The main content of aroma components in 28 kinds of heated cigarette aerosols were 5-hydroxymethyl furfural, solanone, maltol, furfuryl alcohol, β-caryophylene, hexyl acetate, isobutyl acetate, α-Angelica lactone, 2-methyl pyazine, etc; differential flavor components in different samples mainly include L-menthol, ethyl maltol, linalool, vanillin, methyl cyclopentenolone, 3-hydroxy-2-butanone, hexyl acetate, perillamide, WS-23, etc. The above different ingredients are the source of different flavor substances.
