Abstract

An orally-enjoyable tobacco product includes a portion of smokeless tobacco comprising an active ingredient and either: (1) a collection of tobacco particles at least partially enclosed by a coating comprising a water-soluble non-crosslinked component and a substantially water-insoluble cross-linked component, or (2) a pouch comprising smokeless tobacco enclosed in a water-permeable wrapper. The active ingredient is selected from the group consisting of a mercaptan, camphor, borneol, isoborneol, bornyl acetate, isobornyl acetate, mono-bornyl succinate, mono-isobornyl succinate, mono-bornyl formate, and mono-isobornyl formate. The active ingredient is present in an amount effective to reduce or eliminate the sensory irritation arising from the smokeless tobacco. Also disclosed is a method of making such a product.
