Problems solved by technology

Tobacco-flavored e-cigarettes need to add tobacco extracts to provide tobacco aroma. Most of the commercially available tobacco extracts use ethanol as a solvent. After heating and extracting, they are concentrated to prepare extracts without fine separation. The following problems exist in the use of e-cigarettes: One is that the aroma of the cigarette is weak and has a greenish smell. Due to the presence of high-boiling substances such as sugars, proteins,

Abstract

The invention discloses E-cigarette nicotine liquid and a preparation method thereof and belongs to the technical field of E-cigarette nicotine liquids. The E-cigarette nicotine liquid is made from high-nicotine tobacco extract, tobacco flavor and the like, wherein the tobacco extract has rich tobacco characteristic fragrant ingredients (such as megastigmatrienone, beta-damascone, pyrones, and furanones) and nicotine, can provide tobacco aroma and curing aroma and meet the physiological needs of consumers, and provides better satisfaction. The high-nicotine tobacco extract has very low contents of high-boiling-point ingredients and macromolecular substances (such as proteins, pectin, and polysaccharides), is free of burnt smell and low in sweetness, and can supplement aroma and cover peculiar odors, lower stimulus and improve taste strength. By being used with tobacco flavors, the E-cigarette nicotine liquid has enhanced curing aroma and tobacco aroma, and has strong aroma and good volatility. The preparation process of the E-cigarette nicotine liquid is simple, is simple and easy to perform, and is applicable to large-scale industrial production and application.

Description

technical field [0001] The invention relates to an electronic cigarette liquid, and also relates to a preparation method of the electronic cigarette liquid, belonging to the technical field of electronic cigarette liquid. Background technique [0002] E-cigarettes are electronic devices that deliver nicotine to the respiratory system by means of heating. When inhaled, there is a feeling of "breathing the clouds" similar to smoking. Compared with traditional cigarettes, e-cigarettes do not undergo combustion, do not contain harmful components such as tar, CO, and hydrocyanic acid, do not produce second-hand smoke, and do not produce ash and cigarette butts. In recent years, as a substitute for traditional cigarettes, it has developed rapidly in Europe, America and other countries. [0003] E-cigarette liquids mainly use propylene glycol and glycerin as solvents, supplemented with flavors and fragrances to improve the taste, such as coffee extract, mint extract, strawberry ex...
