The disclosure provides products configured for oral use, the products including compositions comprising a porous alumina component and a releasable material that is retained in pores of the porous alumina. The releasable material retained in the pores of the porous alumina may be configured for controlled release therefrom.

A process for preparing an orally-enjoyable film of encapsulated plant material includes combining particles of finely divided plant material, a first coating material, and a second coating material, then inducing gelation to form a gel matrix of the particles coated with the first coating material embedded in the second coating material, followed by forming a film from the gel matrix. Also disclosed is a film of coated particles of finely-divided plant material, made of a gel matrix of plant material at least partially surrounded by a first coating material and embedded in a second coating material.

A capsule for delivery of a flavoring in water-pipe smoke is disclosed herein. The disclosed capsule includes a core bead of an inert material and a coating layer encapsulating the bead. The coating layer contains a flavoring, an absorbent-binder, a mist-maker, a sweetener, a thickener. The coating layer is configured to provide release of the flavoring, sweetener and of the mist-maker when heated.

This invention discloses a kind of microburst-microcapsule designed for cigarettes and a smoking article with such microburst-microcapsules. Wherein the microburst-microcapsule is composed of a microcapsule wall and an aerosol generation material encapsulated by the microcapsule wall. The microburst-microcapsule can be filled in cigarette. When the cigarette lights, the high temperature generated from its combustion zone will vaporize the nearest aerosol generation materials packaged in the aforesaid microburst-microcapsule. The vapor pressure will cause the microcapsule wall burst. As a result, the aerosol from the aforesaid aerosol generation materials will vapor out of the microcapsule wall. Tobacco-free carbonaceous fuels or solid carbonaceous from high temperature vacuum destructive distillation of tobacco filament can be used as combustion materials for aforesaid cigarettes.

An electrically heated smoking article includes a filter layer, a hollow tube layer stacked at a lower end of the filter layer, an aerosol-forming substrate layer stacked below the hollow tube layer and including a mixture of a solid moisture absorbent and a liquid aerosol-forming substrate capsule, and a wrapping portion surrounding the filter layer, the hollow tube layer, and the aerosol-forming substrate layer to maintain a stack structure. The liquid aerosol-forming substrate capsule includes a liquid aerosol-forming substrate at a center, a first emulsifier layer completely surrounding the liquid aerosol-forming substrate, and a first coating material layer covering a surface of the first emulsifier layer.

Embodiments described herein include a ground tobacco composition, wherein at least 90% by weight of the tobacco in the composition has a particle size in the range of about 200 m to about 5 mm.

Described is a pouched product for oral use that includes a liquid permeable cover material and a portion sized amount of a filling material including a water insoluble particulate material, the filling material being enclosed by the liquid permeable cover material. The water insoluble particulate material contains less than 0.5% of particles passing through a sieve having a mesh size of 250 m, the filling material includes one or more water soluble components.

The capsule includes the matrix with one or more portions of a filler material. The filler material is a plant-based cellulose material. The one or more portions define interstices. A containing structure contains the matrix. A consumable substance is infused within the filler material. The consumable substance is nicotine, a flavorant, a pre-aerosol formulation, a combination thereof, or a sub-combination thereof. The device includes a heating section with the capsule.

A smoking article (10) incorporates a liquid release component (20), the liquid release component comprising an inner core of a sustained release liquid delivery material and a frangible outer shell encapsulating the inner core. The liquid delivery material comprises a closed matrix structure comprising a cross-linked polymer matrix defining a plurality of domains; and a liquid composition that is trapped within the domains and is releasable from the closed matrix structure upon compression of the material. The frangible outer coating comprises at least one film-forming polymer and at least one plasticiser.

A process for preparing an orally-enjoyable film of encapsulated plant material includes combining particles of finely divided plant material, a first coating material, and a second coating material, then inducing gelation to form a gel matrix of the particles coated with the first coating material embedded in the second coating material, followed by forming a film from the gel matrix. Also disclosed is a film of coated particles of finely-divided plant material, made of a gel matrix of plant material at least partially surrounded by a first coating material and embedded in a second coating material.
