A preparation method of solidified tobacco extract and its application in electronic cigarettes

Abstract

The invention provides a preparation method of a solidified tobacco extract. The preparation method comprises the following steps: 1) conducting extracting: drying, crushing and sieving tobacco raw materials, and conducting supercritical extraction; 2) conducting separating: dissolving an extract obtained in the step 1) and uniformly mixing the dissolved extract, cooling an obtained solution until the solution becomes layered, conducting filtering to remove lower liquid, and reserving an upper solid so as to obtain a primary shaped material; and 3) conducting shaping: dissolving the primary shaped material with the addition of an atomizing agent, oscillating and uniformly shaking, and condensing and shaping so as to obtain the solidified tobacco extract. Furthermore, the invention also provides an application of the solidified tobacco extract prepared by the method as an aerosol forming matrix in an electronic cigarette. According to the preparation of the solidified tobacco extract and the application of the solidified tobacco extract in the electronic cigarette provided by the invention, various problems caused by the addition of additives as well as flavors and fragrances can be avoided, and such problems as tar leakage and the like caused by conventional electronic cigarette liquid can be also avoided; therefore, the solidified tobacco extract is quite worthy of popularizing and applying.

Description

technical field [0001] The invention belongs to the technical field of electronic cigarettes, and relates to a preparation method and application of a condensed tobacco extract, in particular to a preparation method of a condensed tobacco extract and its application as an aerosol-forming matrix in an electronic cigarette . Background technique [0002] E-cigarette is a new product born in the international tobacco control environment. It is the application of high technology in tobacco products in the new century, and it is a new thing in the field of cigarettes. In recent years, the e-cigarette market has grown exponentially, sales have increased year by year, and domestic and foreign markets are developing rapidly. One of the most important parts of an e-cigarette is the aerosol-forming substrate. The smoke formed when the electronic cigarette is smoked is called aerosol; the solid or liquid material containing tobacco used to generate the aerosol is called the aerosol-f...

AI Technical Summary

Problems solved by technology

[0004] However, although the solid e-cigarette liquid prepared above effectively solves the problems of liquid e-cigarette liquid leakage, backflow, and inconvenient storage and transportation, a large amount of curing agents and excipients are added, and these additives have long-term effects on the lungs. The safety problem of the product has not been verified, and the use of a large number of additives increases the production cost and process difficulty
