  • Tobacco reconstitution process
    Patent number: 5501237
    Abstract: Reconstituted tobacco having good wet strength is provided. Tobacco material is extracted with water to yield an insoluble portion and an aqueous portion containing water soluble tobacco components. The insoluble portion is formed into a sheet-like shape and contacted with a pectin release agent. Alternatively, the insoluble portion is contacted with pectin release agent and then formed into a sheet-like shape. 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.
