Abstract
A method of treating tobacco with a strong acid to inhibit alkaloid loss during drying. The tobacco is then treated with weak base to neutralize the acid. The preferred strong acid is phosphoric. The preferred weak base is ammonium hydroxide. An added benefit of this treatment is burn retardation by ammonium phosphates resulting in cigarette puff number increase.
