Oral tobacco material

Abstract

An oral tobacco material includes a powdered tobacco, and a basic salt of carbonic acid and an acidic salt of phosphoric acid as a pH adjusting agent. The basic salt of carbonic acid and the acidic salt of phosphoric acid are included in a total amount of 6% by weight or more of the dry weight of the powdered tobacco and are incorporated such that the initial pH of the oral tobacco material becomes from 7 to 8.5, and the oral tobacco material has a water content of 15% by weight or more.

1 . An oral tobacco material comprising a powdered tobacco, and a basic salt of carbonic acid and an acidic salt of phosphoric acid as a pH adjusting agent,
 wherein the basic salt of carbonic acid and the acidic salt of phosphoric acid are contained in a total amount of 6% by weight or more of a dry weight of the powdered tobacco and are incorporated such that an initial pH of the oral tobacco material becomes from 7 to 8.5, and the oral tobacco material has a water content of 15% by weight or more.   
     
     
         2 . The oral tobacco material according to  claim 1 ,
 wherein the basic salt of carbonic acid is selected from the group consisting of sodium carbonate and potassium carbonate.   
     
     
         3 . The oral tobacco material according to  claim 1 ,
 wherein the acidic salt of phosphoric acid is selected from the group consisting of sodium dihydrogen phosphate and potassium dihydrogen phosphate.   
     
     
         4 . The oral tobacco material according to  claim 1 ,
 wherein the oral tobacco material comprises the acidic salt of phosphoric acid in an amount of at least 1% by weight of the dry weight of the powdered tobacco.   
     
     
         5 . The oral tobacco material according to  claim 1 ,
 wherein the oral tobacco material is free from magnesium carbonate.
