For example, the sorbent can include, but is not limited to, carbon such as activated carbon, alumina, silicate, molecular sieve, and zeolite. The sorbent can be used alone or in combination. In a preferred embodiment, the sorbent is activated carbon. Gas components can be filtered and removed from tobacco smoke using a porous material such as activated carbon (e.g., a pore sorbent). The pore sorbent can have pores with a width or diameter of less than about 20 Å (angstroms). While the porous material can be effective in filtering tobacco smoke, it can interfere with the ability of a cigarette designer to add volatile flavor components such as menthol. In particular, the pore sorbent tends to absorb and / or adsorb flavor components from the time of tobacco manufacture until consumer use, thereby reducing the efficacy of the flavor components of the cigarette. In addition to the reduction in the efficacy of flavor components due to absorption / adsorption by the pore sorbent, there are two further problems when the flavor components migrate to the sorbent and the sorbent absorbs / adsorbs the flavor components. According to an exemplary embodiment, the flavor components can cause the sorbent to have active sites, thereby reducing the sorbent's ability to remove target gas-phase components from the smoke.

[0035] The term "additive" means any material or component that changes the properties of the cigarette during smoking. One or more appropriate additive materials or combinations of materials can be included within one or more flavorant particles to change the properties of the cigarette 10. Such additives can include other smoke modifiers such as flavors, humectants, and chemical reagents such as 3-aminopropylsilyl (APS). Furthermore, the additive can include diluents, solvents, or processing aids that do not affect or affect the sensory properties of the mainstream smoke and are useful for the treatment of additives and the encapsulation of additives and the production of cigarettes. In an exemplary embodiment, the additive can include one or more flavors such as liquid flavors or solid flavors and flavor formulations or flavor-containing materials. The term "flavor" or "tobacco flavor" can include any flavor compound or tobacco extract that is disposed in a liquid state and is releasable within one or more flavorant particles and is suitable for enhancing the flavor of the mainstream smoke produced, for example, by a cigarette. Suitable flavors or flavorings can include, but are not limited to, menthol, mint flavors such as peppermint and spearmint, chocolate, licorice, citrus and other fruit flavors, γ-octalactone, vanilla, ethylvanillin, breath freshener flavors, spice flavors such as cinnamon, methyl salicylate, linalool, bergamot oil, geranium oil, lemon oil, ginger oil, and tobacco flavors. Other suitable flavors can include acids, alcohols, etc.

It may contain flavor compounds selected from the group consisting of calls, esters, aldehydes, ketones, pyrazines, and combinations or blends thereof.

[0038] For example, according to an exemplary embodiment, the flavor particles 50 can contain from about 1 wt% to about 10 wt% of flavor or flavoring and from 99 wt% to 90 wt% of wax, and more preferably from about 2 wt% to about 5 wt% of flavor or flavoring and from 98 wt% to 95 wt% of wax. For example, according to an exemplary embodiment, the molten wax contains 5 wt% of flavor and 95 wt% of wax. In one embodiment, the additive can serve as a chemical reagent for one or more components of the mainstream smoke. Such additives can include, by way of example, chemical additives that interact with one or more components of the mainstream smoke.

[0039] The flavor particles in the filter structure appear to have advantages particularly for cigarettes containing activated carbon. In a cigarette containing activated carbon in the filter, by placing the flavor particles in the filter downstream of the activated carbon, the activated carbon is substantially prevented from absorbing the released additives and thereby inactivating the carbon. Thus, when the additive is a flavor component, the activated carbon is substantially prevented from absorbing the flavor during storage and smoking of the cigarette.
