Abstract
Flavorful tobacco-derived flavorful components of a tobacco material are provided by extraction of the tobacco material with an extraction solvent in the form of a polyhydric alcohol or ester thereof. The tobacco material is subjected to extraction conditions above about 100.degree. C. and under conditions sufficient to provide the flavorful tobacco-derived extraction product. The tobacco material and the extraction solvent can be contacted in the presence of at least one reaction component such as at least one amino acid and/or at least one sugar.
