The invention provides an smokeless tobacco composition adapted for oral use, the composition including a tobacco material and an effervescent material. The effervescent material includes an acid component and a base component, wherein the acid component includes a triprotic acid such as citric acid and at least one additional acid. The invention also provides a method for making a smokeless tobacco composition that involves first forming a granulation mixture, granulating the granulation mixture, and then blending the resulting granules with further blending components. Thereafter, the material can be formed into a predetermined shape, such as by compression or extrusion. The acid component of the effervescent material is divided into two portions, the first portion added to the granulation mixture and the remaining portion added during the blending step.

A method for producing a flavor source that supports an inhaling flavor component contained in a tobacco raw material, comprises: step A of performing an alkali treatment on the tobacco raw material; and step B of arranging an alkali-treated tobacco raw material and a flavor base material configured by non-tobacco material within a same space in such a way that the alkali-treated tobacco raw material and the flavor base material are maintained in a non-contacting state, thereby inducing the flavor base material to support the inhaling flavor component emitted as a vapor phase from the tobacco raw material.

Methods for creating concentrated plant material solution, including combining ethanol-soluble, water-insoluble concentrated plant material with ethanol to define mixtures and reducing the amount of ethanol in the mixtures until the mixtures have viscosities compatible for use with electronic cigarettes. Some examples include combining ethanol-soluble, water-insoluble concentrated plant material, hydrocarbon bases, and liquid solutions containing ethanol to define mixtures, removing the hydrocarbon bases from the mixtures, and reducing the ethanol content of the mixtures until the mixtures define viscosities compatible for use with electronic cigarettes. Some examples include extracting solute from source materials and including the extracted solute in the ethanol-soluble, water-insoluble concentrated plant material.
