Abstract
Tobacco flavorants loaded into semi-open micro cavities of shaped fibers add flavor to tobacco smoke during the smoking process. The shaped fibers are end-capped shaped multi-lobals that form semi-open cavities between the lobals to effectively entrain solid and liquid flavorant materials. The flavorant material may be in solid particulate forms, such as menthol solids and menthol impregnated carbon or silica gels, and may also be in liquid form such as menthol in dissolved or melt forms.
