Another method of manufacturing flavorant particles includes melting a food grade wax and a flavorant into a molten wax, the molten wax having a melting temperature between about 50° C. to about 70° C.; and spray-chilling the molten wax into at least one solid flavorant particle, the solid flavorant particle having a diameter of between about 0.1 mm to about 2.0 mm.

An aerosol-generating element for an aerosol-generating article or system is provided, the element including: a solid continuous matrix structure; and an aerosol-generating formulation dispersed within the structure, in which the formulation is trapped within the structure and releasable from the structure upon heating of the element, in which the structure is an alginate matrix, in which the formulation consists of: nicotine from 1% by weight to 4% by weight of a total weight of the element, glycerin from 60% by weight to 80% by weight of the total weight of the element, a carboxylic acid from 0.5% by weight to 4% by weight of the total weight of the element, and balance water, in which the formulation dispersed within the structure is at least about 80% by weight of a total weight of the element, and in which the element includes less than 15% by weight of water.

Provided herein are a coating composition of a low ignition propensity cigarette paper, a smoking article using the same, and a method of manufacturing the low ignition propensity cigarette paper. The coating composition of the low ignition propensity cigarette paper according to some embodiments of the present disclosure includes Arabic gum, ethanol, water, and fructo-oligosaccharide. Fructo-oligosaccharide may remarkably delay the aging speed of the coating composition and block even fine pores so that the ignition propensity of the coating composition is significantly reduced.

A process is disclosed for incorporating additives into aerosol-producing substrates. During the process, an additive is incorporated into an infusing liquid. An aerosol-producing filler is submerged in the infusing liquid and the resulting mixture is subjected to reduced pressures that cause the infusing liquid to infuse into the material. The material is dried leaving behind the additive in a controlled amount and uniformly dispersed throughout the material. In one application, cannabidiol is incorporated into a tobacco filler or a hemp filler.

An aerosol-generating element for an aerosol-generating article or system is provided, the aerosol-generating element including: a solid continuous matrix structure; and an aerosol-generating formulation dispersed within the structure, in which the formulation is trapped within the structure and releasable from the structure upon heating of the aerosol-generating element, in which the structure is a polymer matrix including one or more matrix-forming polymers, in which the formulation dispersed within the structure includes at least one alkaloid or cannabinoid compound and a polyhydric alcohol, in which a polyhydric alcohol content in the formulation dispersed within the structure accounts for at least 30 percent by weight based on a total weight of the aerosol-generating element, and in which the aerosol-generating element has an equivalent diameter of at least about 0.5 millimetres and an ovality from about 2 percent to about 30 percent.
