Abstract (en)
[origin: EP3711494A1] A method of producing a flavorant-carrying tobacco filler comprises extracting a water-soluble component contained in a tobacco material with an aqueous solvent from the tobacco material to obtain a tobacco extraction liquid and a tobacco residue, heating the tobacco residue to form a carboxyl group in the tobacco residue, and mixing the tobacco residue having the carboxyl group formed therein with a flavorant having a hydroxyl group to cause an esterification reaction between the carboxyl group and the hydroxyl group, thereby obtaining a flavorant-carrying tobacco residue.
