Abstract
In order to examine the applicability of the exhaust gas components from the tobacco-roasting process as cigarette flavor ingredients, a preliminary study on the composition of the semivolatiles included in the volatiles from roasted tobacco was conducted. A relatively large quantity of sugar pyrolysates (furans, volatile ketones and lactones) in addition to lower fatty acids and the components of essential oils were found in the condensate of the volatiles from roasted flue-cured tobacco. The condensate from roasted burley tobacco contained nicotine and neophytadiene as major components, and a number of other components of essential oils were also found. The above mentioned compounds in the condensate from flue-cured tobacco were assumed to contribute to its burnt-sugar like aroma. A sweet note of the condensate from burley tobacco might be attributable to the high concentration of the components of essential oils.
