Electronic cigarette liquid containing tobacco extract and preparation method thereof

Abstract

The invention discloses an electronic cigarette liquid containing tobacco extract. The electronic cigarette liquid comprises the following components in parts by weight: 1-2 parts of tobacco extract, 10 parts of deionized water, 15-60 parts of glycerol, 26.5-69 parts of propylene glycol, and 0-8 parts of auxiliary materials. A preparation method of the electronic cigarette liquid comprises the following steps of using the flue-cured tobacco leaves, drying and crushing into powder, sterilizing by ultraviolet rays, adding the deionized water, accelerating the solvent extraction, adjusting the pH (potential of hydrogen) value of the obtained extraction liquid to 10-13 by sodium hydroxide, distilling by water steam, re-extracting the distilled liquid by food level ethyl acetate, depressurizing and concentrating the extraction liquid, obtaining the water steam distilling tobacco extract, dripping into a mixture of the deionized water, the glycerol, the propylene glycol and the auxiliary materials, and uniformly stirring, so as to obtain the electronic cigarette liquid. Compared with the prior art, the electronic cigarette liquid has the characteristics that the tobacco extract has no pigment, the content of harmful matters is low, the components are simple, the water solubility and high boiling point are realized, and the electronic cigarette liquid is favorably prepared in the subsequent period.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to an electronic cigarette liquid and a preparation method thereof. Background technique [0002] The World Health Organization Framework Convention on Tobacco Control strictly prohibits cigarette consumers from smoking in public places, and many countries have issued corresponding regulations to prohibit smoking in closed places. Cigarette consumers are dependent on smoking cigarettes, and the success rate of compulsory smoking cessation is low. Therefore, new tobacco products have emerged as excessive smoking cessation products. Electronic cigarette is one of the new tobacco products, which is an electronic delivery device that transmits nicotine to the respiratory system by means of electronic heating. Although electronic cigarettes have the taste of cigarettes, they have no soot, no combustion, no tar, carbon monoxide and other harmful substances. [0003] The preparation method of the ...

AI Technical Summary

Problems solved by technology

CO 2 The tobacco extract obtained by supercritical extraction not only has high harmful components and complex extract components, but also has potential safety hazards, and not all components in the extract are water-soluble, and the components used in the preparation of e-cigarette liquids are required to be water-soluble

The tobacco extract obtained by dry distillation also has the disadvantages of complex extract components and not all components are water-soluble
