Definitions
- the present invention relates to a cigarette mainstream smoke component adsorbent and a cigarette filter comprising the same.
- a flavorant is added to leaf tobacco shreds used in a cigarette in order to adjust the flavor and the taste.
- the flavorant includes a primary flavorant as a casing source and a secondary flavorant as a top flavor.
- the components of the secondary flavorant exhibit relatively high volatility and are likely to be decomposed by heat. Accordingly, when the cigarette containing the secondary flavorant is smoked, the smoker would taste the flavor to a lesser extent because of the volatilization of the secondary flavorant during the storage thereof.
- the secondary flavorant migrates to and is adsorbed on the charcoal, resulting in a partial deterioration of the flavor and taste.
- the charcoal having the secondary flavorant adsorbed thereon suffers a decreased capability of removing tobacco mainstream smoke components.
- Japanese Patent No. 3744953 discloses a tobacco filter incorporating capsules containing a deodorant, such as activated carbon. These capsules are destroyed by external force when stubbing out the cigarette to thereby release the deodorant within the filter, thus eliminating the smoke odor.
- a deodorant such as activated carbon.
- these capsules are destroyed by external force when stubbing out the cigarette to thereby release the deodorant within the filter, thus eliminating the smoke odor.
- the deodorant is encapsulated in the capsules and the capsules are destroyed by external force when stubbing out the cigarette after smoking to thereby release the deodorant within the filter, the deodorant cannot exert its function during smoking the cigarette.

- the cigarette mainstream smoke component adsorbent according to the present invention has its activated carbon covered by a highly airtight glucan film when the cigarette is not smoked (for example, during storage), so that the adsorption of flavorant contained in the cigarette, etc. can be suppressed. Accordingly, the total amount of deliverable flavorant components contained in the cigarette is not decreased before smoking, so that the flavor can be delivered at a relatively high proportion into the mainstream smoke.
- the glucan film When the adsorbent is brought into contact with tobacco mainstream smoke generated by, e.g., repeated smoking actions, the glucan film is for the first time partially dissolved and detached mainly by highly polar components (moisture, etc.) contained in the tobacco mainstream smoke, so that the inherent adsorptive function of the activated carbon can be exerted, thereby attaining the adsorption of gas components contained in the cigarette mainstream smoke.
- tobacco mainstream smoke generated by, e.g., repeated smoking actions
- a 5% by weight concentration aqueous pullulan dispersion was prepared.
- Activated carbon 250 ⁇ m average particle diameter (palm husk activated carbon employed in conventional charcoal filters; specific surface area: 1000 m 2 /g), 15 kg, was placed in a tumbling fluidized-bed granulation drier (Model SFC-15 manufactured by Freund International Ltd.).
