Abstract: Cigarettes are provided which contain a filtering system and flavorants encapsulated with polyvinyl acetate, wherein deactivation of a sorbent by the flavorant is reduced through the encapsulation of the flavorant within the polyvinyl acetate. A preferred flavorant is menthol. The encapsulated flavorants are prepared by mixing at least one flavorant with polyvinyl acetate and a solvent, such as ethanol, and forming the encapsulated flavorants. Methods of making cigarettes and smoking the articles are also provided.

Abstract: Delivery of additives in a smoking article is provided through thermally degradable, robust immobilized additive inserts. Additives can be immobilized in an elongated device or an insert, wherein the elongated device or the insert is sufficiently robust to allow the elongated device or the insert to be manually or machine inserted into a smoking article while maintaining the structure of the elongated device or the insert. By providing additives in the form of thermally degradable immobilized additive inserts, migration and/or loss of the additives in a smoking article prior to smoking can be reduced.

Abstract: A tobacco smoking mixture and/or a cigarette wrapper with high-temperature ammonia-release agents therein are provided, wherein the high-temperature ammonia-release agents are present in an amount effective to reduce the cytotoxicity of gas phase or particulate matter formed during smoking of the cigarette. The high-temperature ammonia-release agents can be formed by heating an aqueous mixture of an iron precursor compound, an ammonia source compound and an acid.

Abstract: Improved delivery of additives is provided through encapsulation. The encapsulated additives can be formed by encapsulating additives using co-ionic cross-linking, in-situ overcoating, and/or step-growth overcoating. By encapsulating additives, additives can be made heat and moisture stable and migration and/or loss of the additives within a cigarette, such as an activated carbon containing cigarette, can be reduced.

Abstract: Electrically heated cigarettes used in an electrical smoking system include a flavoring-release additive and sorbent effective to remove one or more gas-phase constituents of mainstream tobacco smoke. The flavoring-release additive includes gamma cyclodextrin and at least one flavoring. Flavoring is released in a cigarette upon the flavoring-release additive reaching at least a minimum temperature during smoking. The flavoring-release additive can have various forms including, for example, powder and films.

Abstract: A tobacco smoking mixture and/or a cigarette wrapper with high-temperature ammonia-release agents therein are provided, wherein the high-temperature ammonia-release agents are present in an amount effective to reduce the cytotoxicity of gas phase or particulate matter formed during smoking of the cigarette. The high-temperature ammonia-release agents are capable of reducing the cytotoxicity of gas phase or particulate matter by evolving ammonia at temperatures greater than about 200° C., wherein the ammonia can interact with the particulate matter. Additionally, the high-temperature ammonia-release agents can be formed by heating an aqueous mixture of an iron precursor compound, an ammonia source compound and an acid.
