ABSTRACT:
A process for degreening and coloring tobacco by subjecting the tobacco to air containing ethylene gas and thereafter wilting, dehydrating and curing. The air containing ethylene gas is exchanged within a controlled environment at a substantially high rate to not only replenish the oxygen and nitrogen content, but also to remove the carbon dioxide generated in the coloring process that can inhibit further coloring. The process also permits increasing the temperature around the tobacco during the wilting and dehydrating stages so as to substantially decrease the total time required for curing the tobacco.
