Description
Technical Field
The invention belongs to the technical field of heating cigarettes, and particularly relates to a particle material capable of heating and releasing aerosol, and a preparation method and application thereof.
Background
The heating non-burning cigarette is mainly characterized in that an external heat source is utilized to heat a material containing tobacco components, so that substances such as flavor components in the tobacco are released under the heating condition. Because the material containing the tobacco components does not participate in combustion, a large amount of harmful components generated by pyrolysis are avoided. The consumer obtains sensory experience, simultaneously reduces the harm of released substances to human bodies, and simultaneously reduces environmental pollution. According to research results, the aerosol of the heated non-combustible cigarette is reduced by more than 90 percent compared with the traditional cigarette smoke, and can provide the nicotine level basically equivalent to the cigarette.
The existing heating cigarette smoking material generally has three forms of tobacco sheets, tobacco leaves and tobacco reconstituted grains, wherein the existing tobacco reconstituted grains are prepared by adding aerosol products, tobacco extracts, tobacco essence and other substances into the crushed tobacco leaves and adopting a powder reconstituted grain process.
CN117137177a discloses a low-hygroscopicity heating cigarette tobacco granule and a preparation method thereof, the tobacco granule takes a low-hygroscopicity pill core parent core as an inner core, and an outer layer containing tobacco components is wrapped outside the inner core. The invention adopts the low-hygroscopicity pill core as the parent nucleus material, which has no negative effect on the sensory quality, greatly reduces the hygroscopicity of tobacco particles and obviously improves the quality stability of cigarettes.
CN116138486a discloses a preparation method of a feed liquid and a tobacco filler for heating cigarettes and a granular heating cigarette, the preparation method comprises: mixing tobacco fragments with water, heating and refluxing, and collecting tobacco essential oil and water extraction residues; adding ethanol solution into the water extraction residue for heating reflux, and collecting leaching solution and ethanol extraction residue; freezing the leaching solution, and centrifugally filtering to obtain a first extract; cooling and drying the alcohol extraction residues, performing carbon dioxide supercritical extraction, and collecting a second extract and supercritical residues; mixing tobacco essential oil, the first extract and the second extract to prepare a feed liquid for heating cigarettes; adding a feed liquid into the second tobacco to prepare tobacco particles, thereby obtaining a first tobacco filler; and soaking the residue-loaded material in essence, and drying to obtain the second tobacco filler. By adopting the method, the production cost can be reduced while the quality of the flue gas is improved; the whole process is environment-friendly, and no waste water and waste residue are generated.
However, the above method mainly has the disadvantages of complex process, high energy consumption, and loss of aroma components in tobacco leaves in the preparation process, and influence on the quality of products, so that it is necessary to develop a heating-releasing aerosol particle material which has a simple process and is easy to store.
