Abstract: A smoking article includes a smokable material and a filter downstream of the smokable material. The filter comprises a capsule having a core and a breakable shell. The core has a mixture including one or more lipid compounds and one or more humectants. The lipid compounds account for 50% or more of the weight of the mixture. At least one of the one or more humectants is capable of interacting with one or more smoke constituents to reduce the concentration of the one or more smoke constituents in mainstream smoke.

Abstract: There is provided a smoking article (100) incorporating an additive delivery system. The additive delivery system comprises a frangible capsule (110) comprising a breakable shell containing a liquid core. The shell can be broken by means of a pressure to release a single burst of the liquid core. Further, the additive delivery system comprises a sustained-release liquid delivery material (111) comprising a liquid composition. The liquid composition is releasable in discrete amounts from the liquid delivery material upon compression of the liquid delivery material so as to selectively combine the first and second additive. The frangible capsule and the sustained-release liquid delivery material are spaced apart, such that a consumer can separately and selectively activate the release of additive from either component of the delivery system.

Abstract: A smoking article (10) incorporates a liquid release component of a sustained release liquid delivery material (20) comprising a closed matrix structure having a polymer matrix defining a plurality of domains. A liquid composition is trapped within the domains and is releasable from the closed matrix structure upon compression of the material. The polymer matrix is formed of one or more polysaccharides cross-linked by multivalent cations. The concentration of multivalent cations in the closed matrix structure varies such that along a line extending through the liquid release component from the outer surface of the closed matrix structure to the centre of mass of the liquid release component, the highest concentration of multivalent cations within 250 microns from the outer surface is at least 1.5 times the highest concentration of multivalent cations within 500 microns from the centre of mass.

Abstract: A smoking article (10) incorporates a liquid release component of a sustained release liquid delivery material (20), the liquid delivery material comprising a closed matrix structure having a polymer matrix defining a plurality of domains. A liquid composition is trapped within the domains and is releasable from the closed matrix structure upon compression of the liquid release component. The polymer matrix is formed of one or more anionic polysaccharides cross-linked by multivalent cations. A filler comprising one or more amphiphilic polysaccharides is incorporated within the polymer matrix. The one or more amphiphilic polysaccharides of the filler are selected from starch chemically modified to be amphiphilic and starch derivatives chemically modified to be amphiphilic.

Abstract: A method for the production of a flavour granule for a smoking article comprises the steps of: a) forming an inner core by compaction of particles of herbaceous plant material; b) providing a coating suspension of coloured binder particles comprising at least one colourant and at least one polymeric binder in a solvent; c) applying the coating suspension to the outer surface of the inner core to form an outer layer, wherein the coating suspension is applied to the inner core within a coating system and wherein within that coating system the vapour pressure of the solvent is greater than 5 kPa; and d) drying the outer layer to evaporate the solvent.
