ABSTRACT:
The present invention relates to a process for providing a tobacco extract. A tobacco material and extraction solvent are provided physically separated from each other. The extraction solvent is then volatized. The tobacco material is subjected to extraction conditions by contacting the tobacco material with the volatized extraction solvent to provide a tobacco extract within the volatized extraction solvent. The extraction conditions include (i) maintaining the pressure of the tobacco material and extraction solvent at less than about 10 mm of Hg pressure and (ii) maintaining the tobacco material and extraction solvent at a temperature of greater than about 30.degree. C. and less than the boiling point at atmospheric pressure of the volatized extraction solvent.
