A smokeless tobacco product configured for insertion into the mouth of a user of the product is provided, the tobacco product including a water-permeable pouch containing a tobacco formulation, the tobacco formulation including a tobacco material and a plurality of microcapsules dispersed within the tobacco material, the plurality of microcapsules including an outer shell encapsulating an internal payload. The internal payload may include an additive such as water, flavorants, binders, colorants, pH adjusters, buffering agents, fillers, disintegration aids, humectants, antioxidants, oral care ingredients, preservatives, additives derived from herbal or botanical sources, and mixtures thereof. Microencapsulated flavorants include tobacco-containing flavorants, such as tobacco extracts or a particulate tobacco material, sweeteners (e.g., sweeteners containing neotame), and vanillin (optionally in a complexed form).

The smokeless tobacco product of claim 1, wherein the payload of the microcapsules further comprises a tobacco-containing flavorant. 3. The smokeless tobacco product of claim 2, wherein the tobacco-containing flavorant comprises a tobacco extract or a particulate tobacco material. 4. The smokeless tobacco product of claim 1, wherein the payload of the microcapsules further comprises neotame. 5. The smokeless tobacco product of claim 1, wherein the payload of the microcapsules further comprises vanillin optionally in a complexed form. 6. The smokeless tobacco product of claim 1, wherein the microencapsulated sugar beet fiber material is present in an amount of at least about 5 percent based on the weight of the dry formulation. 7. The smokeless tobacco product of claim 1, wherein the payload of the microcapsules further comprises a buffering agent. 8. The smokeless tobacco product of claim 7, wherein the buffering agent buffers within a pH range of about 6 to about 10. 9.
