FLAVOR BEAD AND CIGARETTE FILTER

摘要

Disclosed is a perfumed bead comprising a particulate carrier and a glucan film and a perfume material both supported on the particulate carrier. The emission of the aroma from the perfume material is regulated by the glucan film. The perfume material is carried in the perfumed bead so that the aroma of the perfume material is emitted when the glucan film contacts with a main-stream smoke of a cigarette and the dissolution of at least a part of the glucan film is caused.
