Abstract
Cellulose granules small enough such that they can be retained in a cigarette filter and capable of carrying sufficient amounts of volatile functional substance and vaporizing it easily. The cellulose granules are obtained from an extrusion granulating step and a spheronizing step, with smaller variability in particle diameter than that of conventional cellulose granules.
