Whitened tobacco composition |
| abstract |
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. |
