Abstract
A process for manufacturing reconstituted tobacco with reduced nitrogenous content by submitting cured tobacco material, including whole leaf, stems, scraps, fines and lamina, as well as burley leaf and stem, to an extraction with a solution containing sodium acetate, sodium hydroxide, potassium hydroxide or mixtures thereof. The extraction process, in addition to denitrifying the tobacco material, also produces reconstituted tobacco paper with characteristics similar to flue cured tobacco leaf.
