Therefore, the organoleptic properties of the aerosol-modifying agent can be readily perceived by the user, lower quantities of aerosol-modifying agent may need to be added to the aerosol-generating material to achieve the desired aerosol characteristics and the aerosol produced by the aerosol generating material can be used to carry a wide variety of different aerosol-modifying agents.

- the encapsulated aerosol-modifying agent may exhibit an aroma that is indicative of the flavour of the aerosol-modifying agent.

Accordingly, the increased flow of mainstream smoke enhances the delivery of the smoke modifying additive to the consumer and the smoking article ic can therefore exhibit improved delivery of a smoke modifying additive to a consumer compared to conventional smoking articles.
- An aerosolisable material was made as follows. Water and sodium alginate (Protanal® RF6650; 8% on a dry weight basis) were combined and mixed in a high-shear mixer for
- Exemplary Embodiment - Aerosol-Generating Material The aerosolisable material prepared as described above was blended with tobacco material to produce an aerosol-generating material comprising tobacco and the aerosolisable material.
- the relative quantities of aerosolisable material and tobacco material in the aerosol-generating material are shown in Table 1.
- the tobacco comprised tobacco leaf in an amount of about 50 wt% based on the total weight of the composition.
- About 40 wt% of the tobacco leaf was leaf obtained from the lower half of the tobacco plant and had a ratio of sugars to nicotine of about 10:1.
- the aerosol-generating material comprised tobacco stem in an amount of about 18 wt% based on the total weight of the composition.
- Cigarettes comprising the aerosol-generating material maybe marketed under the name “White Tobacco”.
- One cigarette did not comprise any additional flavourants.
- the other two cigarettes comprised a flavourant (menthol, 1 mg).
- the configurations are shown in Table 2.
- Cigarettes 1 to 3 were evaluated by a panel of expert smokers against a Control Cigarette which did not contain the aerosolisable material as described herein (Kent Super Slim (1 mg menthol)).
- Cigarettes 1 to 3 exhibited better after taste, better flavour perception and better mouthfeel compared with the Control Cigarette.
- Various embodiments of the invention may suitably comprise, consist of, or consist essentially of, appropriate combinations of the disclosed elements, components, features, parts, steps, means, etc, other than those specifically described herein.
