Tobacco filling for non-combustion-type heating smoking article

Abstract

The purpose of the present invention is to provide a tobacco filling: that is for a non-combustion-type heating smoking article that heats a filling that contains cut tobacco; that suppresses reductions in the evaporated amount of a fragrant smoke flavor component for the non-combustion-type heating smoking article; and that can suppress the “feeling that fragrant smoke flavor is being inhibited.” According to the present invention, a dihydrogen salt of a trivalent or tetravalent acid that has a first acid dissociation constant of 1.0 or lower is added to a tobacco filling, and, as a result, reductions in the evaporated amount of a fragrant smoke flavor component can be suppressed, as can “the feeling that fragrant smoke flavor is being inhibited.”

What is claimed is: 
     
         1 . A tobacco filler for a non-combustion smoking article comprising a shredded tobacco, and a liquid that generates aerosol, wherein
 the tobacco filler contains a dihydrogen salt of a trivalent or quadrivalent acid having a first acid dissociation constant of 1.0 or less.   
     
     
         2 . The tobacco filler according to  claim 1 , wherein the dihydrogen salt is a dihydrogen salt of pyrophosphoric acid. 
     
     
         3 . The tobacco filler according to  claim 1 , containing the dihydrogen salt at 0.1% by mass to 10% by mass inclusive of the whole tobacco filler. 
     
     
         4 . The tobacco filler according to  claim 1 , wherein the liquid that generates aerosol contains propylene glycol. 
     
     
         5 . The tobacco filler according to  claim 1 , containing water at 5.0% by mass to 30% by mass inclusive of the whole tobacco filler.
