Problems solved by technology

[0005] However, the above-mentioned flavor sustained-release method is not applicable to heat-not-burn tobacco products
Because its heating temperature is much lower than the combustion temperature of traditional cigarettes, some aroma precursors cannot be cracked to produce flavor substances, or the flavor and fragrance wrapped in it cannot be released because the cracking temperature of the microcapsule wall material is not reached, or it is only Relying on the adsorption capacity of the adsorbent, it is impossible to achieve slow and uniform release of flavors and fragrances
[0006] In addition, there are also a small number of research reports on the flavor release technology of heat-not-burn tobacco products, but only for monomer flavors with certain special structures or categories, and the technical means are limited, especially the lack of general flavor release technology research
For example, the Chinese patent document with the publication number CN102821628 A provides a supramolecular complex fragrance immobilization and controlled release technology, which utilizes the non-covalent bond interaction between the supramolecular compound and the fragrance fragrance to realize the control of the fragrance fragrance. release, the patent mainly involves simple fragrance materials such as menthol and lemon oil, and does not describe the fragrance slow-release effect of essences or fragrance bases with complex components

Embodiment 1

[0066] Flavor A is a commonly used cigarette flavor, which contains some common volatile and semi-volatile flavor components, mainly including: water, ethyl butyrate, ethyl 2-methyl butyrate, ethyl isovalerate, furfural, Hexyl caproate, 3-methyl-pyrazine, 2-ethyl-3-methylpyrazine, benzaldehyde, acetophenone, macrostigmatrienone, geranylacetone, β-damascenone, di Hydrodamascone, menthol, methyl phenylacetate, tobacco extract, fig extract, apple extract, jujube tincture, vanilla bean tincture, benzoin balm, licorice liquid extract, etc.

[0067] In order to promote the slow and uniform release of flavor A during the heating stage, this solution uses hydroxypropyl methylcellulose as a sheet substrate to fix flavor A and applies it to the heating end of the heat-not-burn tobacco product. The specific implementation method is as follows: Weigh 4g of hydroxypropyl methylcellulose (food grade, produced in India), and add about 30ml of water to completely dissolve the hydroxypropylmet...

Embodiment 2

[0076] Another optimized implementation is to use an adsorbent to absorb flavors and fragrances, then add hydroxypropyl methylcellulose solution to make flavor slow-release sheets, and apply them to the heating end of heat-not-burn tobacco products. The specific steps are as follows: take the activated The final diatomite is passed through a 40-mesh sieve, dried in an oven at 500°C for 12 hours, and cooled at room temperature for later use; mix essence A with 40-mesh diatomaceous earth at a ratio of 2:1, stir well, and then add an appropriate amount of hydroxypropyl methyl Base cellulose (the ratio of the three is 2:1:4), add about 10 times the volume of water to dissolve the hydroxypropyl methylcellulose to form a viscous liquid, stir well until the absorbent and flavors and fragrances are evenly dispersed; The above liquid is evenly coated on a flat plate, and the solvent is removed by drying with hot air at 30°C to obtain a thin sheet with a thickness of about 0.5mm; it is c...

Embodiment 3

[0079]Hydroxypropyl methylcellulose was used as substrate to immobilize fragrance A, and cyclodextrin was added as adsorbent. The specific implementation steps are as follows: Weigh 1g of cyclodextrin, mix it with 2g of essence A, and equilibrate at room temperature for 0.5h; then add 4g of hydroxypropyl methylcellulose, dissolve it with about 40ml of water to form a viscous liquid, and stir it fully to make it Disperse evenly; apply the above liquid on a flat plate, remove the solvent by evaporating at room temperature, and obtain a thin-film sustained-release composite material with a thickness of about 0.5mm; cut the thin slice and blend it into heat-not-burn tobacco products at a ratio of 2% in tobacco materials.

[0080] The test results show that the hydroxypropyl methylcellulose flavor sustained-release sheet added with cyclodextrin can significantly improve the uniformity of flavor and fragrance release in heat-not-burn tobacco products, which is beneficial to the flav...

Abstract

The invention belongs to the technical field of heat-not-burning cigarettes, and particularly discloses a hydroxypropyl methyl cellulose-based aroma sustained-release material for heat-not-burning tobacco products, wherein the hydroxypropyl methyl cellulose-based aroma sustained-release material comprises a hydroxypropyl methyl cellulose base material and a cigarette aroma material compounded in the hydroxypropyl methyl cellulose base material. The invention also provides a composite sheet compounded with the sustained-release material. The invention also provides preparation methods of the sustained-release material and the composite sheet, and an application method of the sustained-release material and the composite sheet in heat-not-burning cigarettes. According to the invention, with the application of the material in a heat-not-burning tobacco product, the technical problems that the flavoring technology of the heat-not-burning tobacco products is too fast in fragrance release, the first fragrance is too strong, the second fragrance is basically volatilized completely, the products are difficult to endow specific quality style characteristics and the like are overcome; and thearoma slow-release effect of the product can be remarkably improved, the smoking sensory quality is improved, and the product is endowed with stable quality style characteristics.

Description

technical field [0001] The invention relates to a method for slow-release of flavor of heat-not-burn tobacco products and an application thereof, and belongs to the technical field of slow-release of flavor of novel tobacco products. Background technique [0002] Heat-not-burn tobacco products (low-temperature cigarettes) are a new type of tobacco products with flavor characteristics closest to traditional cigarettes. The harmful chemical components and biological toxicity of smoke are relatively low, and they are currently the development focus of the tobacco industry in various countries around the world. [0003] However, since the tobacco material part of heat-not-burn tobacco products continues to be in a "high temperature environment" of about 200-350°C from the first puff of smoke, it is significantly different from the "puff-by-puff combustion" of traditional cigarettes, resulting in the release of flavor substances , especially the highly volatile added fragrance su...
