Abstract

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 total amount of saccharides contained in the tobacco raw material is 9.0 wt % or less when a gross weight of the tobacco raw material in the dry state is 100 wt %. The first condition is determined based on variations in the pH of the collection solution. The second condition is determined based on the remaining amount of nicotine component.
