ABSTRACT:
Concentrated tobacco extracts are provided by first extracting water soluble components from tobacco. The aqueous extract then is spray dried to a dry powder form. As such, the extract is in a low solvent form (i.e., the solvent content including moisture content of the extract is less than about 12 weight percent). The spray dried extract is contacted with a lower alcohol such as methanol or ethanol, and certain components are extracted from the spray dried extract. The resulting extracted components are isolated from the alcohol solvent in order to yield a tobacco essence. The essence has a homogeneous, viscous character and exhibits a tobacco aroma. The essence is useful as a flavoring agent for cigarettes and other smoking articles.
