Purposes To study the relationship between the aroma components and the different carbonation temperatures.
Methods The same finished tobacco samples were designed and manufactured. The types of aroma components were determined by HS-GC-MS at different carbonation temperatures (80, 100 and 120 ℃), and the interaction between them was studied.
Results (1) The finished tobacco was carbonized from 80 ℃, and the carbonization was obvious at 120 ℃. From low temperature to high temperature, the color changed from golden to brown. (2) At 80, 100 and 120 ℃, the mass spectra of the parallel test were basically the same, and 18, 52 and 81 aroma components were detected. The molecular weight range was 44.026−241.077 u. (3) From low temperature to high temperature, the number of fragrant substances in different carbonation temperature was 4, 13 and 36 species respectively.
Conclusions With the increase of temperature, the number of incense components is increasing. Among them, at 100 ℃, the characteristic aroma components included amines, alcohols and sulfides, oxygen-containing polycyclic compounds and the molecular weight ranged 40 from 200 u; at 120 ℃, ketones, alcohols, ethers and nitrogen-containing polycyclic compounds and the molecular weight ranged 50 from 160 u.
