Abstract
A method of fixing a flavorant for improving the small of a sidestream smoke of tobacco. This method includes applying, to tobacco wrapper paper, a tobacco sidestream smoke smell-improving agent including an ethanol or propylene glycol solution of the flavorant added to an emulsion of an ethylene-vinyl acetate copolymer having an ethylene content of 30% by weight or less, the emulsion having a solid content of 10 to 60% by weight, and drying it to fix the flavorant to the wrapper paper. The ethanol solution of the flavorant is added to the emulsion such that an amount of ethanol is 40% by weight or less with respect to 100% by weight of the emulsion, while the propylene glycol of the flavorant is added to the emulsion such that an amount of propylene glycol is 11% by weight or less with respect to 100% by weight of the emulsion.
