  • Patent number: 4318417
    Abstract: Flavorant composition for tobacco may be produced by heating certain synthesized inorganic ion-exchangeable compound containing zirconium or titanium metal together with tobacco flavorant in organic solvent to adsorb the flavorant to the exchanger. This flavorant composition may be applied advantageously to filter cigarette so as to be added to the portion of filter tip in the form of triple-filter or dual-filter. The flavorant in the flavorant composition having been added to filter tip scarcely volatilizes when it has only been left as it is, however such flavorant may be released readily from the composition by wet smoke passing through the filter tip when smoked, whereby aroma and taste of the flavorant may effectively be produced. The amount of tobacco flavorant capable of producing moderate aroma and taste is far lesser than that of flavorant that has customarily been added to the portion of blended cut tobacco.
