FLAVOR BEAD AND CIGARETTE FILTER

摘要

A flavor bead includes a particulate carrier, a glucan film supported by the particulate carrier, and a flavorant. The flavorant is supported by the flavor bead such that release of flavor from the flavorant is suppressed by the glucan film, but the flavor is released by the glucan film being at least partially dissolved when the glucan film contacts with tobacco mainstream smoke.
