Abstract
An oral tobacco composition is provided which has a 0.06 or greater ratio (A/N) of the total amount of carboxylic acid with 6 or fewer carbon atoms to the nicotine content, and which has a 20 ng or lower TSNA content per 1 mg of nicotine.
Claims11
An oral tobacco composition, wherein a molar ratio (A/N ratio) of total content of carboxylic acid having carbon number of six or less with respect to content of nicotine is 0.06 to 2.00, and content of tobacco-specific nitrosamines (hereafter referred to as TSNA) per 1 mg of nicotine is 20 ng or less.
A method for producing an oral tobacco composition containing a tobacco material obtained through steps a) to f) below, the obtained tobacco material having properties (i) and (ii) below, and
- the method comprising:
- a) step of adding a basic substance to a tobacco material;
- b) step of heating the tobacco material, to which the basic substance has been added, to cause a flavor component in the tobacco material to be released into a gas phase;
- c) step of recovering, in a collecting solvent, the flavor component having been released into the gas phase;
- d) step of washing, by using a washing solvent, the tobacco material from which the flavor component has been released, to remove thereby an acidic substance remaining in the tobacco material;
- e) after the step d), a step of adding a carboxylic acid having carbon number of six or less to the tobacco material, or a step of adding a carboxylic acid having carbon number of six or less to the collecting solvent of the step c);
- and
- f) step of, after the step e), returning the flavor component recovered in the step c) to the tobacco material,
- (i) a molar ratio (A/N ratio) of total content of carboxylic acid having carbon number of six or less and content of nicotine is 0.06 or higher;
- and
- (ii) content of TSNA per 1 mg of nicotine is 20 ng or less.
