Reconstituted Tobacco has ammonia incorporated therein. Tobacco is extracted with water to yield an insoluble portion and an aqueous portion containing water soluble tobacco components. The aqueous portion is contacted with ammonia to yield an ammoniated extract. The extract is applied to the insoluble portion which has been formed into a sheet-like shape. The resulting tobacco composition is dried to yield a reconstituted tobacco material treated with ammonia.
