See full text

An extraction method of a flavor constituent comprises: a step A for heating a tobacco raw material which is subjected to an alkali treatment; and a step B for bringing a release component released in the gas phase in the step A into contact with a collection solvent at normal temperature until any time from when a first condition is satisfied to when a second condition is satisfied. The first condition is determined based on a residual rate of nicotine component. The second condition is determined based on a remaining amount of nicotine component.
