Abstract: A method of manufacturing a flavor source includes: a step A of adding a basic substance to a tobacco raw material; a step B of heating the tobacco raw material added with the basic substance and releasing an inhaling flavor component into a vapor phase from the tobacco raw material; a step C of collecting the inhaling flavor component released into the vapor phase in the step B; a step D of washing a tobacco residue being the tobacco raw material obtained after the inhaling flavor component is released in the step B, with a washing solvent; a step E of pulverizing or cutting the tobacco residue obtained after being washed in the step D; and a step F of adding the inhaling flavor component collected in the step C to the tobacco residue obtained after pulverized or cut in the step E.

Abstract: A producing method of a tobacco raw material comprises: a step A1 for heating a tobacco raw material in a closed space which is treated with alkali and for taking a flavor constituent released in the gas phase from the tobacco raw material to an outside of the closed space; a step B1 for allowing a first solvent to capture the flavor constituent by bringing the flavor constituent released in the gas phase in the step A1 into contact with the first solvent which is a liquid substance at normal temperature on the outside of the closed space; and a step C1 for adding the first solvent capturing the flavor constituent in the step B1 to the tobacco raw material in the closed space after the step B1.

Abstract: A producing method of a tobacco raw material containing a flavor constituent, comprises: a step A for heating a tobacco raw material in a closed space which is treated with alkali and for taking a flavor constituent released in the gas phase from the tobacco raw material to an outside of the closed space; a step B for allowing a first solvent to capture the flavor constituent by bringing the flavor constituent released in the gas phase in the step A into contact with the first solvent which is a liquid substance at normal temperature on the outside of the closed space; a step C for supplying a second solvent to the tobacco raw material in the closed space after the step A and for taking a normal component which is released as the liquid phase from the tobacco raw material to the second solvent, together with the second solvent to the outside of the closed space; and after the steps B and C, the step D for adding the first solvent capturing the flavor constituent in the step B to the tobacco raw material from
