A preparation method of tobacco aroma substance for electronic cigarette liquid

Abstract

The invention discloses a method for preparing a tobacco herbal fragrant substance for cigarette solution of an electronic cigarette. The method comprises the steps that waste and inferior tobaccos are extracted in an ultrasound-enhanced supercritical extraction device for 1.5-2 hours at the temperature of 40-55 DEG C in the presence of an entrainer under the conditions that the ultrasonic frequency is 20KHz, the ultrasonic power is 100W, the flow rate of carbon dioxide of 10-20L / h and the extraction pressure is 15-25 MPa, so as to prepare a mixed solution of carbon dioxide and the tobacco herbal fragrant substance, wherein the entrainer is a mixed solvent of propylene glycol, ethanol and distilled water; the mixed solution is separated by virtue of a separation kettle at temperature of 45- 60 DEG C under the separation pressure of 7-12MPa to obtain the tobacco herbal fragrant substance. The tobacco herbal fragrant substance contains tobacco natural fragrant substance components, nicotine and the like and is applied to the cigarette solution of the electronic cigarette so that the cigarette solution of the electronic cigarette is endowed with the same sense organ characteristic and a satisfaction sense of smoking as common cigarettes. The extraction method is easy to carry out, low in cost, and stable and safe in product quality; the environment pollution is avoided; compared with the conventional supercritical extraction process, the method has the advantage that material consumption and energy consumption are reduced.

Description

technical field [0001] The invention relates to a preparation method of a tobacco aroma substance used in electronic cigarette liquid. Background technique [0002] Electronic cigarettes, also known as electronic cigarettes, are mainly used to quit smoking and replace cigarettes. It has the same appearance and taste similar to cigarettes, and even has a lot more flavor than ordinary cigarettes. It can also suck out smoke, taste and feeling like cigarettes. E-cigarettes do not have other harmful components such as tar and suspended particles in cigarettes, and there is no diffuse or lingering second-hand smoke in e-cigarettes. E-cigarette liquid is the essence extracted from plants and added with edible flavors. It has strong oxidation resistance and does not contain harmful substances such as carbon monoxide and tar. In order to ensure that e-cigarettes can bring smokers the same sensory quality as cigarettes, it is necessary to add spices, nicotine and other substances t...
