Abstract

The invention discloses a method for preparing an electronic cigarette liquid through microwave-assisted extraction. An extraction liquid and mixed tobacco leaves are mixed and irradiated by microwaves, organic phases are merged after filtering and washing operation, an organic solvent is finally removed, and a tobacco leaf extract is obtained, wherein the extraction liquid and the mixed tobacco leaves are mixed in the weight ratio being (1:1)-(5:1); the adopted power is 400-800 W during microwave irradiation; the faint-scent tobacco leaf extract is prepared from Yunnan Yuxi faint-scent tobacco leaves, Yunnan Dali faint-scent tobacco leaves and Yunnan Qujing faint-scent tobacco leaves. By comparison with conventional extraction methods such as a room-temperature extraction method and a heating reflux method, the extraction time is greatly shortened, the use quantity of solvents is reduced, and the extraction efficiency is remarkably improved. Besides, the extract is prepared from mixed tobacco leaf extracts, and different tobacco leaf extracts complement each other in scent, so that the scent and the taste of the electronic cigarette liquid are more close to those of conventional cigarettes.

Description

technical field [0001] The invention relates to a method for preparing electronic cigarette liquid by using microwave-assisted extraction. It belongs to the field of tobacco chemical industry. Background technique [0002] E-cigarettes are currently a widely popular alternative to cigarettes. There have been many literature and patent reports on the preparation and preparation of e-liquid in e-cigarettes. [0003] In order to imitate the original flavor of traditional cigarettes, a method of preparing e-cigarette liquid by using tobacco leaf extracts combined with tobacco flavors and flavors has been developed. For example, a preparation method of electronic cigarette liquid (patent application No. 201110184068.6), a flue-cured tobacco type electronic cigarette liquid (patent application No. 201110263484.5), an electronic cigarette liquid that can effectively improve the sensory quality of electronic cigarettes (patent application No. ) and so on disclosed the preparation...
