Tobacco Product, Preparation and Uses Thereof

Abstract

A smokeless oral tobacco product comprises a cyclodextrin or cyclodextrin derivative. Such a product can further comprise a flavourant complexed with the cyclodextrin or derivative thereof. Cyclodextrins or their derivative can be used in smokeless oral tobacco products to complex with molecules which arise or solubilize during use of the product and optionally to also release, e.g., flavour or aroma during use of the product.
