Tobacco material

Abstract

A tobacco material comprises an aqueous dispersion medium and tobacco particles that are dispersed in the dispersion medium and have an average particle size of 30 μm or less, where a hemicellulose content in the tobacco material is 0.8% by weight or less based on bone-dry tobacco particles. The tobacco material exhibits low viscosity as a feature.

1 . A tobacco material comprising an aqueous dispersion medium and tobacco particles that are dispersed in the dispersion medium and have an average particle size of 30 μm or less, wherein
 a hemicellulose content in the tobacco material is 0.8% by weight or less based on bone-dry tobacco particles. 
 
     
     
         2 . The tobacco material according to  claim 1 , wherein a pH is 4.8 or less. 
     
     
         3 . The tobacco material according to  claim 1 , wherein the aqueous dispersion medium contains an aqueous organic compound. 
     
     
         4 . The tobacco material according to  claim 3 , wherein the aqueous organic compound is selected from the group consisting of monohydric alcohols, polyhydric alcohols, sugar alcohols, sugars, polyhydric alcohol esters, and combinations thereof. 
     
     
         5 . The tobacco material according to  claim 1 , wherein a water content in the aqueous dispersion medium exceeds 50% by weight. 
     
     
         6 . The tobacco material according to  claim 1 , wherein a content of the tobacco particles is 1 to 40% by weight. 
     
     
         7 . The tobacco material according to  claim 1 , wherein the tobacco particles are particles derived from a tobacco raw material, a fermented tobacco raw material, or a heat-treated tobacco raw material. 
     
     
         8 . The tobacco material according to  claim 7 , wherein a variety of the tobacco raw material is flue-cured, burley, domestic, or oriental. 
     
     
         9 . A production method for the tobacco material according to  claim 1  comprising:
 preparing a dispersion containing an aqueous dispersion medium and tobacco particles that are dispersed in the dispersion medium and have an average particle size of 30 μm or less; and 
 heating the dispersion to 160° C. or higher. 
 
     
     
         10 . The production method according to  claim 9 , wherein the heating is performed under pressure. 
     
     
         11 . A tobacco product comprising the tobacco material according to  claim 1 . 
     
     
         12 . The tobacco product according to  claim 11 , further comprising a base material, wherein 0.01 to 5% by weight of the tobacco particles are contained relative to the base material. 
     
     
         13 . A production method for the tobacco product according to  claim 12  comprising adding the tobacco material to the base material.
