Abstract
The amount of polycyclic aromatic hydrocarbons in tobacco smoke is reduced and a substantially diminished biological activity of the tobacco smoke condensate when evaluated on experimental animals following conventional protocol is achieved by adding to the tobacco palladium, either in metallic or salt form, and an inorganic nitric oxide generating compound.
Claims28
A smoking tobacco composition comprising
- tobacco,
- palladium in an amount of from about 0.001 to about 1 weight percent based on the weight of the tobacco, and an inorganic nitrate salt in an amount of from about 0.25 to about 0.75 weight percent calculated as added nitrate nitrogen
A smoking tobacco composition comprising:
- a. tobacco, and
- b. a catalytic mixture consisting, essentially of palladium, in an amount of from about 0.01 to about 0.1 weight percent based on the weight of the tobacco and a non-toxic inorganic nitrate salt in an amount of from about 0.25 to about 0.75 weight percent calculated as added nitrate nitrogen based on the weight of the tobacco.
A smoking tobacco composition comprising
- a. a blend of tobaccos containing up to about 21 percent by weight reconstituted tobacco;
- b. magnesium nitrate, in an amount of from about 0.25 to about 0.75 weight percent calculated as added nitrate nitrogen based on the weight of the tobacco;
- and
- c. palladium, in an amount of from about 0.01 to about 0.1 weight percent based on the weight of the tobacco.
A smoking tobacco composition which comprises the product of the process of mixing tobacco and an aqueous solution of a palladium salt in an amount of from about 0.01 to about 0.1 weight percent calculated as palladium and an inorganic nitrate salt in an amount of from about 0.25 to about 0.75 weight percent calculated as added nitrate nitrogen, said weight percents of palladium and nitrate salt being based on the total weight of the tobacco in the smoking composition.
