摘要： 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.

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.Cellulose fibers with an average fiber length of 0.1 mm to 0.5 mm and an average polymerization degree of 400 to 1200 are used.
