Abstract
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.
