Process for modifying the flavour characteristics of bright tobacco
1988
Driscoll, D.M. | Southwick, E.W.
The tobacco is treated with liquid ammonia, which dissolves some of the components of the tobacco, and these dissolved components are separated by evaporation of the ammonia and recombined with the treated tobacco. Recombination can be affected simply by evaporating the ammonia while the solution remains in contact with the tobacco or by separating the solution from the tobacco, evaporating the ammonia, dissolving the residue in water or alcohol and then recombining with the treated tobacco. The effect of the treatment or bright tobacco, especially with a moisture content of 4 to 22%, is to add some burley character to the bright tobacco.
