Embodiment 1

[0068] Flavor A is a commonly used conventional cigarette flavor, which is applied to heat-not-burn tobacco products in the present invention, and the flavor components contained therein mainly include: ethyl acetate, ethyl butyrate, ethyl 2-methylbutyrate, isovaleric acid Ethyl esters, furfural, hexyl caproate, 3-methyl-pyrazine, 2-ethyl-3-methylpyrazine, benzaldehyde, acetophenone, macrostigmatrienone, geranylacetone, beta- Damascenone, dihydrodamascenone, menthol, methyl phenylacetate, tobacco extract, fig extract, apple extract, date tincture, vanilla bean tincture, benzoin balm, licorice liquid extract, etc. For the thermogravimetric curve of essence A, see figure 1 , the analysis shows that when the temperature reaches 150°C, more than 60% of the essence A has been lost due to rapid volatilization. The essence is directly injected into the heating end of the heat-not-burn tobacco product with a flavoring injection device. The evaluation results show that there is a stro...

Embodiment 2

[0074] Another optimized implementation is to use an adsorbent to absorb flavors and fragrances, and then add polyvinyl alcohol 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 activated diatoms Pass the soil through a 40-mesh sieve, dry it in an oven at 500°C for 12 hours, and cool it at room temperature for later use; mix the essence A with 40-mesh diatomaceous earth in a ratio of 1:1, stir evenly, and place it in a room temperature environment for 0.5 hours; After dissolving polyvinyl alcohol (pharmaceutical grade, type 1788) with 10 times the volume of water, add it to the above system and stir well until the absorbing material and flavor and fragrance are evenly dispersed in the polyvinyl alcohol liquid; spread the above liquid evenly On a flat plate, the solvent is removed by hot air drying at 30°C to obtain a sustained-release sheet; it is cut into filaments with a le...

Embodiment 3

[0077] According to the method of Example 2, the adsorbent is replaced by Hβ-molecular sieve, and the essence B is used as the slow-release essence. The aroma components contained in the essence B mainly include: ethyl acetate, ethyl propionate, ethyl butyrate, isovaleric acid Ethyl esters, ethyl caproate, furfural, 3-methylpyrazine, amyl valerate, benzyl alcohol, ethyl caprylate, benzyl acetate, ethyl caprate, macrostigmazonone, beta-damascenone, Damascone, Geranylacetone, Sclare Oil, Lemon Oil, Tobacco Extract, Cocoa Extract, Vanilla Bean Tincture, Iris Extract, Licorice Fluid Extract, etc. The prepared flavor sustained-release thin slices are cut into shreds and blended into the tobacco material of heat-not-burn tobacco products. It also has a good sustained-release effect, which can make the flavors and fragrances release slowly and uniformly between 100-250°C, and release continuously The time is more than 25 minutes, and the weight loss rate is 13% within 15 minutes.

Abstract

The invention belongs to the technical field of heat-not-burn cigarettes, and particularly discloses a polyvinyl alcohol-based aroma sustained-release material for heat-not-burn tobacco products. Thematerial comprises a polyvinyl alcohol base material and a cigarette aroma material compounded in the polyvinyl alcohol base material. The invention also provides a composite sheet compounded with thesustained-release material. In addition, 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-burn cigarettes. The invention innovatively discovers that the material is applied to the heat-not-burn tobacco product, and can overcome the technical problems that the first aroma is too strong, the second aroma is basically volatilized completely, the product is difficult to endow specific quality style characteristics and the like caused by quick aroma release in the flavoring technology of the heat-not-burn tobacco product. The aroma sustained-release effect of the product can be remarkably improved, the smoking sensory quality is improved, andthe 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, during the smoking process of heat-not-burn tobacco products, the heating part of the tobacco is always in a heated state as a whole, resulting in the release of aroma substances, especially the release of highly volatile additional aroma substances is very uneven. After two puffs, it will basically evaporate completely, and it is difficult to keep the t...
