ABSTRACT:
Tobacco extracts are provided by first extracting tobacco material with water and then subjecting the resulting aqueous tobacco extract to a liquid/liquid extraction process using a long chain alcohol. Preferably, the pH of the aqueous extract is adjusted to about 9 or above prior to the liquid/liquid extraction step. The two immiscible solvents then are separated from one another such that there is provided an aqueous tobacco extract having certain extracted tobacco components removed therefrom and long chain alcohol solvent having extracted tobacco components carried thereby. The processed aqueous extract can be spray dried to provide a concentrated tobacco extract which then can be employed as flavorful forms of tobacco for cigarette and other smoking articles.
