Description

The present invention relates to aerosol-generating substrates containing homogenized plant material obtained from cumin seed particles, and to aerosol-generating articles incorporating such an aerosol-generating substrate. The present invention also relates to an aerosol obtained from an aerosol-generating substrate containing cumin seed particles. Aerosol-generating articles in which an aerosol-generating substrate, such as a tobacco-containing substrate, is heated rather than combusted are known in the art. Typically, in such articles, the aerosol is generated by heat transfer from a heat source to a physically separate aerosol-generating substrate or material, which may be located in contact with, within, around, or downstream of the heat source. During use of the aerosol-generating article, volatile compounds are released from the substrate by heat transfer from the heat source and are entrained in air drawn through the article. As the released compounds cool, they condense to form an aerosol. Some aerosol-generating products contain a flavor additive that is delivered to the consumer during use to provide a different sensory experience, such as enhancing the aerosol's mouthfeel. The flavor additive can be used to deliver a taste sensation (flavor), an olfactory sensation (smell), or both a taste and olfactory sensation to the user inhaling the aerosol. Providing heated aerosol-generating products containing flavor additives is known. Flavoring additives are also commonly found in conventional combustible cigarettes. These are smoked by lighting the end of the cigarette opposite the mouthpiece, causing the tobacco rod to burn, generating inhaled smoke. One or more flavoring additives are typically mixed with the tobacco in the tobacco rod to impart an additional flavor to the inhaled smoke as the tobacco burns. Such flavoring additives can be provided, for example, as essential oils. The aerosol from a regular cigarette, which contains numerous components that interact with receptors located in the mouth, produces a sensation of "mouth fullness," that is, a relatively strong sensation in the mouth. "Mouthfeel," as used herein, refers to the physical sensations in the mouth caused by a food, drink, or aerosol and is distinct from taste. It is a fundamental sensory attribute that, along with taste and odor, determines the overall flavor of a food product or aerosol. There are challenges in replicating the consumer experience of traditional combustible cigarettes in aerosol-generating products, where the aerosol-generating substrate is heated rather than burned. This is partly due to the lower temperatures achieved during heating of such aerosol-generating products, which results in a different profile of the volatile compounds released. It would be desirable to provide a new aerosol-generating substrate for a heated aerosol-generating article that delivers an aerosol with improved mouthfeel and mouthfeel. It would be particularly desirable if such an aerosol-generating substrate could deliver an aerosol with a sensation comparable to that of a conventional combustible cigarette. It would also be particularly desirable if such an aerosol-generating substrate could deliver an aerosol with reduced levels of undesirable aerosol compounds compared to existing aerosol-generating substrates, such as those containing only tobacco. It would also be desirable to provide such an aerosol generating substrate that can be easily incorporated into an aerosol generating article and that can be manufactured using existing high-speed methods and devices. The present invention relates to an aerosol-generating article comprising an aerosol-generating substrate, wherein the aerosol-generating substrate is formed from homogenized plant material including cumin seed particles, referred to herein as "homogenized cumin-based material." The homogenized cumin-based material may further comprise an aerosol-forming substance. The homogenized cumin-based material may further comprise a binder. The aerosol-generating substrate may further comprise at least approximately 15 micrograms of procurcumenol per gram of substrate, based on dry weight. The aerosol-generating substrate may further comprise at least approximately 20 micrograms of cuminaldehyde per gram of substrate, based on dry weight. The aerosol-generating substrate may further comprise at least approximately 10 micrograms of isothymol per gram of substrate, based on dry weight. According to the present invention, an aerosol-generating article is provided, comprising an aerosol-generating substrate, wherein the aerosol-generating substrate is formed from a homogenized cumin-based material including cumin seed particles. According to the present invention, the homogenized cumin-based material comprises: cumin seed particles, an aerosol-forming substance, and a binder. The aerosol-generating substrate further comprises at least about 15 micrograms of procurcumenol per gram of s
