This method for producing a cigarette ingredient that contains a fragrant inhalation component includes: a step A for heating an alkali-treated cigarette ingredient within a closed space, and drawing out from the closed space a fragrant inhalation component released as a vapor phase from the cigarette ingredient; a step B for bringing the fragrant inhalation component that was released as a vapor phase in step A into contact outside the closed space with a first solvent that is a liquid substance at normal temperature, thereby trapping the fragrant inhalation component in the first solvent; a step C following step A, for supplying a second solvent to the cigarette ingredient within the closed space, and drawing out a normal component released from the cigarette ingredient as a liquid phase into the second solvent, from the closed space together with the second solvent; and a step D following step B and step C, for adding the first solvent in which the fragrant inhalation component was trapped in step B, to the cigarette ingredient from which the fragrant inhalation component was released to outside the closed space in step A. |
