摘要： A method of preparing a whitened tobacco material is provided, the method including the steps of (i) extracting a tobacco material with an aqueous solution to give a tobacco pulp and a tobacco extract; (ii) treating the tobacco pulp with at least one of a caustic reagent and an oxidizing agent for a time and at a temperature sufficient to lighten the color of the tobacco pulp to give a whitened tobacco pulp; (iii) clarifying the tobacco extract to remove higher molecular weight components; and (iv) combining the whitened tobacco pulp with a clarified tobacco extract to form a whitened tobacco material. The whitened tobacco material can be isolated and incorporated into a smokeless tobacco product. The invention also provides a smokeless tobacco product incorporating a whitened tobacco material. The smokeless tobacco product may be a snus-type formulation contained within a sealed pouch.

摘要： A smokeless tobacco product is configured for insertion into the mouth of a user and incorporates materials from
Nicotiana species (e.g., tobacco-derived materials) and plant materials from non-
Nicotiana species (e.g., non-tobacco plant materials). The tobacco material can have the form of processed tobacco material (e.g., granulated, reconstituted, heat treated, or otherwise processed tobacco laminae and/or stem), tobacco extract (e.g., an extract of water soluble tobacco components obtained by extracting tobacco with water), or a combination thereof. The non-tobacco material can have the form of vegetable pulp (e.g., sugar beet pulp), pulp obtained after removal of water soluble components as a result of water extraction treatment, or a combination thereof. The tobacco product is composed of a mixture of the tobacco material and non-tobacco material components; such as a mixture of tobacco material, tobacco extract and processed non-tobacco material, or a mixture of aqueous tobacco extract and water-extracted vegetable pulp.
