Ground tobacco composition

Abstract

Embodiments described herein include a ground tobacco composition, wherein at least 90% by weight of the tobacco in the composition has a particle size in the range of about 200 μm to about 5 mm.

1 . A liquid composition for use in a smoking article, heat-not-burn article, or electronic cigarette, comprising a liquid tobacco extract and an aerosol generating agent selected from the group of glycerol, propylene glycol, triacetin and isopropyl myristate,
 the liquid composition comprising substantially no tobacco particles having a particle size of less than 200 μm.   
     
     
         2 . The liquid composition according to  claim 1 , wherein the tobacco from which the liquid tobacco extract is derived is Virginia tobacco. 
     
     
         3 . The liquid composition according to  claim 2 , wherein the liquid composition comprises a concentration of less than about 116 ng/g benzo (a) pyrene; and/or less than about 962 ng/g Cd; and/or less than about 870 ng/g Pb; and/or less than about 1932 ng/g Cr; and/or less than about 951 ng/g Ni; and/or less than about 350 ng/g As; and/or less than about 52.4 ng/g Se; and/or less than about 22.3 ng/g Hg in the liquid tobacco extract. 
     
     
         4 . The liquid composition according to  claim 1 , wherein the tobacco from which the liquid tobacco extract is derived is Burley tobacco. 
     
     
         5 . The liquid composition according to  claim 4 , wherein the liquid composition comprises a concentration of less than about 5.26 ng/g benzo (a) pyrene; and/or less than about 196 ng/g Cd; and/or less than about 673 ng/g Pb; and/or less than about 4001 ng/g Cr; and/or less than about 1993 ng/g Ni; and/or less than about 158 ng/g As; and/or less than about 23.2 ng/g Se; and/or less than about 16.2 ng/g Hg in the liquid tobacco extract. 
     
     
         6 . The liquid composition according to  claim 1 , wherein an extraction solvent is used to obtain the liquid tobacco extract. 
     
     
         7 . The liquid composition according to  claim 6 , wherein the extraction solvent is different to the aerosol generating agent. 
     
     
         8 . The liquid composition according to  claim 7 , wherein the extraction solvent is a supercritical fluid. 
     
     
         9 . The liquid composition according to  claim 1 , comprising at least about 10 wt % of water in the liquid composition. 
     
     
         10 . The liquid composition according to  claim 1 , comprising at most about 14 wt % of water in the liquid composition. 
     
     
         11 . The liquid composition according to  claim 1 , comprising at least about 10 wt % of water in the liquid tobacco extract. 
     
     
         12 . The liquid composition according to  claim 1 , comprising at most about 14 wt % of water in the liquid tobacco extract. 
     
     
         13 . The liquid composition according to  claim 1 , wherein the liquid tobacco extract is derived from tobacco leaf. 
     
     
         14 . The liquid composition according to  claim 1 , wherein the liquid tobacco extract is obtained from a ground tobacco composition, wherein at least 90% by weight of the tobacco in the composition has a particle size of at least about 200 μm.
