The flavor and aroma characteristics of the smoke of a tobacco blend incorporating Oriental tobacco are improved by subjecting that blend to heat treatment. Oriental tobacco having a relatively high sucrose ester content is combined with a second dissimilar Oriental tobacco material and/or a non-Oriental tobacco material to form a tobacco mixture, and that mixture is heated for a time and under conditions sufficient to reduce the concentration of sucrose esters in the Oriental tobacco. Tobacco blends having reduced levels of sucrose esters yield smoke that does not possess undesirable off-notes provided by pyrolysis products of those sucrose esters; namely, 2-methylpropionic acid, 3-methylbutyric acid and 3-methylpentanoic acid.

Method of reducing the sucrose ester concentration of a tobacco mixture

Cigarettes which heat but do not burn tobacco are described, preferably having a carbonaceous fuel element extruded around a physically separate aerosol generating means, comprising an aerosol forming material. These cigarettes are capable of producing substantial quantities of aerosol, both initially and over the useful life of the article, without significant thermal degradation of the aerosol former and without the presence of substantial pyrolysis or incomplete combustion products. Preferably, a barrier member is provided to substantially prevent fluid flow between the aerosol generating means and the fuel element. The barrier member is disposable as the cigarette burns back. Also described are embodiments wherein the aerosol generating means encircles at least a portion of the extruded fuel element. In addition, apparatus and method for making smoking articles are described.
