[0005] Preferably, in step S1, sodium starch octenyl succinate and maltodextrin are added to water and stirred at 40-50° C. and a stirring speed of 500-800 r / min until sodium starch octenyl succinate and maltodextrin are completely dissolved; and / or, In step S2, the alcohol-soluble flavor and the stock solution are stirred at 40-50° C., with a stirring speed of 500-800 r / min and a stirring time of 20-40 min.
[0006] Preferably, stirring is performed in a constant temperature water bath; In step S2, the alcohol-soluble flavor is slowly added dropwise into the stock solution under stirring.
[0007] Preferably, in step S3, homogenization is performed at room temperature, the homogenization rate is 7000-10000 r / min, and the homogenization time is 15-30 min.
[0008] Preferably, in step S4, drying is performed in any one of the following ways: Air dry naturally at room temperature; Dry at 40-50℃ for 12-18h; Freeze-dry at -40℃ - -60℃ for 20-30h.

[0010] Preferably, in step S4, 80-150 mesh screen is used for sieving; and / or, In step S5, the maximum diameter of the alcohol-soluble flavor sustained-release tablets obtained by tabletting is less than or equal to 5 mm.
[0011] An alcohol-soluble flavor sustained-release tablet prepared by any of the preparation methods described above.
[0012] A cigarette, wherein the cigarette filter rod is provided with a viewing window, and the above alcohol-soluble flavor sustained-release tablet is arranged in the viewing window.
[0013] Microcapsule technology is a micro-packaging technology for storing solids, liquids or gases. It uses natural or synthetic polymer materials as wall materials to wrap the contents to form microcapsules. After the core material is microencapsulated, it can be released again through external stimulation or sustained release. The release time and release rate of the core material can be controlled, so that the application time can be extended and the validity period can also be extended. This application utilizes the above-mentioned characteristics of microcapsules, and uses sodium octenyl succinate starch and maltodextrin, which are harmless to the human body and will not have adverse effects on the tobacco smoking taste, to wrap the alcohol-soluble flavor, reduce the influence of the external environment and its own loss, and can effectively enhance the stability of the flavor; the alcohol-soluble flavor is solidified in the wall formed by sodium octenyl succinate starch and maltodextrin, and there are a large number of micropores on the microcapsule wall. The alcohol-soluble flavor can be released through the micropores, which delays the natural release rate of the alcohol-soluble flavor, prolongs the release process, and also reduces the loss of the flavor during processing, transportation, storage and release.
[0014] Specifically, the present application first provides a method for preparing an alcohol-soluble flavor sustained-release tablet, comprising the following steps: S1, mixing sodium starch octenyl succinate, maltodextrin and water to obtain a stock solution; S2. Mix the alcohol-soluble flavor with the stock solution to obtain a mixed solution. S3. Homogenize the mixed solution to obtain an emulsion. S4. Dry, crush and sieve the emulsion to obtain alcohol-soluble flavor sustained-release microcapsules. S5. Compress the alcohol-soluble flavor sustained-release microcapsules into tablets to obtain alcohol-soluble flavor sustained-release tablets.
[0015] The present application also provides an alcohol-soluble flavor sustained-release tablet prepared by the above-mentioned preparation method, which has high stability and can prolong the effect time and storage time of the aroma during the cigarette smoking process.
[0016] The applicant found that directly adding microcapsules wrapped with flavors to cigarette shreds or filter rod tows still has problems such as insufficient fragrance, short storage time, and loss of fragrance during transportation. The present application microencapsulates flavors and spices, then agglomerates and extrude them into sheets, and then applies them to the field of cigarette flavoring, which can further improve the stability and sustained release performance of the flavors, extend the fragrance retention time, and effectively reduce the loss of fragrance during processing, transportation, and storage, and improve the fragrance release effect during the smoking process.
[0017] In order to facilitate the placement of the alcohol-soluble flavor sustained-release tablet into cigarettes, it is preferred that the maximum diameter of the tablet is less than or equal to 5 mm. For example, the alcohol-soluble flavor sustained-release tablet is made into a round tablet with a diameter of 4 mm and a thickness of 2 mm; it can also be made into a spherical shape or other shapes.
[0018] The present application also provides a cigarette with the alcohol-soluble flavor sustained-release tablet added. Specifically, the alcohol-soluble flavor sustained-release tablet is added to the window of the cigarette filter rod, and consumers can directly observe it in the hollow window of the cigarette filter rod, which not only enhances the flavor of the cigarette, but also has a good visual effect, further innovating the appearance design of the cigarette, making the innovative cigarette product novel and unique, and better able to attract the interest of consumers.
[0019] The types of flavors used in this application are not particularly limited, as long as they are alcohol-soluble flavors, commercially available tobacco flavors can be used. The flavors can be mint, pineapple, lemon, jasmine, and the like. This application is to encapsulate commercially available flavors with sodium octenyl succinate starch and maltodextrin to achieve the effects of increasing stability and prolonging the release process. Different types of alcohol-soluble flavors are used to prepare alcohol-soluble flavor sustained-release tablets with different aromas and flavors to enrich the flavor of cigarettes. When using colored alcohol-soluble flavors, the intensity of the fragrance can also be reflected by the depth of the color of the microcapsule.
[0020] In step S4, natural air drying is used after post-treatment to avoid unnecessary loss of flavor caused by temperature. At the same time, the water content after ethanol washing is low enough, and ethanol is highly volatile, so it can be removed by natural air drying without the need for freeze drying. Considering the temperature and cost, natural air drying is the best treatment method. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Comparative Example 1 The same as Example 5, except that the stock solution formula is changed to: 5g maltodextrin, 10g sodium starch octenylsuccinate, and 10g deionized water.
[0034] The alcohol-soluble flavor sustained-release tablets prepared in Examples 5-7 and Comparative Example 1 were placed in a hollow filter rod of a cigarette, and the macroscopic morphology and odor were evaluated as follows:
[0035] The alcohol-soluble flavor sustained-release tablets prepared in Examples 5-7 are placed in a hollow filter rod and present different colors. After smoking, the alcohol-soluble flavor has a fresh and obvious aroma, a full aroma, good permeability, and a relatively coordinated overall smoke, which improves the quality characteristics of the cigarette products and improves the problem of aroma loss during storage of cigarette products.
[0036] In Comparative Example 1, too little maltodextrin, sodium starch octenylsuccinate and deionized water are used, resulting in an excessively high concentration of flavor in the alcohol-soluble flavor sustained-release tablets. As a result, the odor is strong, making the aroma part account for too large a proportion of the entire flue gas, thereby covering up the original taste of the flue gas itself, resulting in a poor effect.
