Abstract (en)
[origin: US2003159703A1] Flavored carbon useful as a filtering material of a smoking article such as a cigarette is made by applying liquid flavorant to activated carbon particles in a fluidized bed. The flavored carbon can be used to impart desired taste to mainstream smoke while removing one or more components from mainstream smoke.
