摘要：
Reconstituted tobacco has phosphate salts 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 adjusted to a pH of about 7, and contacted with diammonium hydrogen orthophosphate. The extract then 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.
