Abstract (en)
A method for extracting a flavor component wherein the flavor component is extracted from a tobacco raw material, said method comprising step A for heating an alkali-treated tobacco raw material having been treated with an alkali and step B for contacting a released component, which has been released into a gas phase in step A, with a collecting solvent, characterized in that: in step A, the initial moisture content of the alkali-treated tobacco raw material is not less than the minimum moisture content required for dissolving the total amount of the alkali; during the heat treatment, water is added to the alkali-treated tobacco raw material; and the moisture content of the alkali-treated tobacco raw material is not more than 35 wt%, relative to the total weight of the tobacco raw material, throughout the whole method.
