Abstract
Abstract An article of manufacture comprising tobacco and a small but effective amount of one or a mixture of monoesters of monoand/or di-alkylmalonates as a flavorant composition. The indicated malonates decompose during smoking of the tobacco by decarboxylation to give the corresponding alkanoate esters which improve the taste and aroma of tobacco smoke. For example, monoethyl sec-butylmalonate in a cigarette at a level of about one ppm on the tobacco will produce a smoke flavor characterized by a fermented apple-peel with an English walnut-like taste. The flavor and taste apparently arise from the conversion of the monoethyl sec-butylmalonate to ethyl Beta -methylvalerate.
