The present disclosure provides a substrate which includes microcrystalline cellulose, a binder, an aerosol forming material, and optionally an active ingredient, a flavorant, or both an active ingredient and a flavorant. The final form of the substrate can be configured for use in aerosol generating components for aerosol delivery devices. Further provided are aerosol generating components and aerosol delivery devices including the substrate. Such devices utilize electrically generated heat or combustible ignition sources to heat the substrate, providing an inhalable substance in the form of an aerosol.

There is provided a flavour system for use in a tobacco industry product. The flavour system comprises lyophilised botanical material, an activator capable of releasing flavourant from the lyophilised botanical material through contact of the activator with the lyophilised botanical material, and a removable barrier preventing contact between the lyophilised botanical material and the activator. The barrier is removable to permit the activator to contact the lyophilised botanical material, thereby to cause release of the flavourant.

An embodiment of the present disclosure provides a method of flavoring and aging smoking materials, the method including: adding a flavoring, which is diluted in a base solution, to a smoking material; and aging the smoking material, to which the flavoring is added, under constant temperature and humidity conditions.

The invention provides a method of manufacturing an amorphous solid, the method comprising: a) forming a slurry comprising a particulate botanical material, a gelling agent and an aerosol-former material; b) forming a layer of the slurry; and c) drying the slurry to provide the amorphous solid.

A solvent for aerosol-generating material includes predominantly 1, 3-Propanediol and glycerol, wherein the 1, 3-Propanediol is less than 50% by weight based on the total weight of the solvent. In particular, it is shown also herein that when the ratio of 1, 3-Propanediol to glycerol is 3:7, the solvent significantly improves for example thermal stability as well as decreases inhaled flavours concentrations.

A substrate is provided comprising an aerosol-generating material, the aerosol-generating material comprising a thermoreversible amorphous solid, the thermoreversible amorphous solid comprising: 0.5-20 wt % of iota- and/or kappa-carrageenan; 20-80 wt % of an aerosol-former material; 20-70 wt % of a flavorant and/or an active substance; wherein these weights are calculated on a dry weight basis. Consumables and non-combustible aerosol provision systems comprising the substrate, as well as methods of making and using these, are also provided.

An aerosol-generating material including an amorphous solid, wherein the amorphous solid includes: 1-60 wt % of a gelling agent; 5-80 wt % of an aerosol-former material; and 10-60 wt % of an active substance; wherein these weights are calculated on a dry weight basis, and wherein the gelling agent includes alginate and pectin, wherein a ratio of the alginate to the pectin is from 1:1 to 10:1.

The invention relates to a population of particles for use in a non-combustible aerosol provision system, wherein each particle comprises (i) a binder, (ii) an absorbent, wherein the absorbent comprises silica or a silicate, and (iii) an aerosol-generating material, wherein the population of particles has a bulk density of between about 0.5 and about 1.1 g.Math.cm.sup.−3 or wherein the median particle size, D50, is between about 1 mm and about 2 mm. The invention also relates to a cartridge for use in a non-combustible aerosol provision system, to a non-combustible aerosol provision system and to a method of manufacturing the particles.

Disclosed herein are compositions and methods for oral delivery of nicotine and nicotine derivatives. In one embodiment the nicotine is delivered in an oral packets, pouches, or sachets.

The present disclosure provides component-containing extruded structures, which include various components entrapped within a base material matrix, and to products containing such component-containing extruded structures. The disclosure also includes a method for entrapping the components, including mixing the component or components with a base material in water, extruding the mixture, and removing at least a portion of the water therefrom. The resulting component-containing extruded structure can then be incorporated within various products, e.g., consumable products such as aerosol-generating devices and components, oral and smokeless products, and conventional smoking articles.
