Abstract: Flue-cured tobacco can be treated with burley tobacco flavor components and subjected to volume expansion conditions. Flavor components are supercritically extracted from burley tabacco and directly applied to the flue-cured tobacco while the extraction fluid is in a supercritical or subcritical state.

Abstract: Cut shredded or otherwise comminuted tobacco is treated with a volatile flavoring additive in a continuous process wherein the additive is combined with a polyhydric alcohol carrier and the additive/polyhydric alcohol combination is applied to the tobacco [by gas-atomizing spray nozzle means] under controlled conditions.

Abstract: A continuous process and apparatus for applying treating fluids to tobacco involves a vertically disposed tower or chamber that is provided with tobacco inlet and outlet means, a plurality of cooperating, vertically spaced baffles arranged in alternating fashion and a plurality of spraying devices located within the tower or chamber at points intermediate the inlet and outlet means. Tobacco and treating fluid are introduced into the tower or chamber at controlled flow rates via the tobacco inlet means and spraying devices, respectively, to give tobacco treated with the desired quantities of treating fluid.
