Problems solved by technology

[0004] However, the above-mentioned fragrance sustained release method is not fully applicable to HNB
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
In addition, there are also a small number of research reports on the flavor release technology of heat-not-burn tobacco products, but most of them are aimed at monomer flavors with certain special structures or categories, such as menthol and β-ionone. Research on Fragrance Sustained Release Technology with Applied Value

Embodiment 1

[0071] Flavor A is a commonly used tobacco 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, geranyl acetone, β-damascenone, Damascone, menthol, methyl phenylacetate, tobacco extract, fig extract, apple extract, jujube tincture, vanilla bean tincture, benzoin balm, licorice liquid extract, etc.

[0072] In order to promote the slow and uniform release of essence A during the heating stage, the weight of this scheme is 17g / m 2 Highly absorbent hemp pulp paper (using Manila hemp pulp, water absorption ≈5g / m 2 ) is the support material to adsorb and fix the essence A. The specific implementation method is as follows: Weigh 360g of essence A, 90g of hydroxypropyl methylcellulose, and 3kg of 85% ethanol solution and mix them together. After the ma...

Embodiment 2

[0076] Another kind of optimized embodiment adopts the highly absorbent cigarette paper stick paper (adopting Canadian northern wood wood pulp, water absorption ≈7.5g / m2) with a grammage of 25.5g / m2 2 ). The specific steps are as follows: first coat the essence A on the paper, remove the solvent, and then coat a layer of film material on the surface.

[0077] The specific steps of this scheme are as follows: Weigh 360g of essence A, dilute to 3kg with 85% ethanol solution and stir evenly. The fragrance solution was coated on the paper material, and the coated paper material was transported to the drying box along with the conveyor belt, and dried at a low temperature of 50° C. to remove moisture, and the fragrance slow-release material A was obtained. Then prepare 3kg of 3% hydroxypropyl methylcellulose solution and apply it on the material A to obtain the final fragrance sustained-release material. By comparing the weight of the paper before and after coating, it can be see...

Embodiment 3

[0080] In another optimized embodiment, the essence A and the film material are mixed and coated on the paper, and after the solvent is removed, a layer of film material is coated on the surface. This program uses highly absorbent cigarette stick paper with a grammage of 25.5g / m2 (Canadian northern wood pulp, water absorption ≈7.5g / m2) 2 ).

[0081] The specific steps are as follows: Weigh 500g of essence A, 90g of hydroxypropyl methylcellulose, and 2410g of 85% ethanol solution and mix them together, stir evenly after completely dissolving, and obtain the flavoring coating liquid. The fragranced coating solution is applied to the paper material by scraping, and the coated paper material is transported to the drying box along with the conveyor belt, and after drying at 50°C to remove moisture, the fragrance sustained-release material A is obtained. . It is 3% hydroxypropyl methylcellulose solution that preparation 3kg concentration is again, is coated on the fragrance slow-r...

Abstract

The invention belongs to the technical field of heat-not-burn tobacco products, and particularly discloses a fragrance slow-release material which comprises a paper base material and a polymer layer compounded on the surface of the paper base material, and the paper base material and / or the polymer layer contain / contains flavors and fragrances. The invention also provides a preparation method andapplication of the fragrance sustained-release material, and also comprises a heating rod and a cigarette holder rod compounded with the fragrance sustained-release material, and a heat-not-burn tobacco product. The invention innovatively discovers that a high-adsorbability paper base material is used as a framework material, the surface of the framework material is coated with a polymer, and flavors and fragrances are distributed in the paper base material and / or the polymer, so that the fragrance sustained-release material is obtained. The paper base material is innovatively used as a bearing material, and the adsorption and encapsulation effects of the paper base material and the polymer on the flavors and fragrances are further utilized, so that the immobilization and slow release of the flavors and fragrances can be effectively realized.

Description

technical field [0001] The invention relates to a flavor slow-release material and its application in heat-not-burn tobacco products, belonging to the technical field of novel tobacco products. Background technique [0002] Heat-not-burn tobacco products (also known as low-temperature cigarettes, HNB) are a new type of tobacco products with flavor characteristics closest to traditional cigarettes, and the harmful chemical components and biological toxicity of smoke are lower. However, because the tobacco material part of HNB is continuously in the "high temperature environment" of about 180-350 ° C, which is significantly different from the "puff-by-puff combustion" of traditional cigarettes, resulting in the release of flavor substances, especially the highly volatile external flavor substances. It is not uniform, and it is often completely volatilized in the first and second sips. The difference in taste before and after smoking is large, and it is difficult to guarantee i...
