Abstract

See full text

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.
