| titleOfInvention | A kind of preparation method of cigarette butt tar extract and its application in cigarette |
| abstract | The invention provides a preparation method of a cigarette butt tar extract and its application in cigarettes. The method comprises the steps of extracting waste cigarette butts with supercritical carbon dioxide to obtain a tar extract; wherein, the extraction pressure is 20-50 MPa , the temperature is 20 ~ 80 ℃. The invention uses waste cigarette butts as raw materials, utilizes supercritical carbon dioxide extraction to prepare tar extract, and is applied to heat-not-burn cigarettes to improve the aroma, smoke and taste characteristics of heat-not-burn cigarettes, and effectively solve the problem of heat-not-burn cigarette aroma. Issues such as slack. The invention obtains tar extract with higher extraction rate from waste cigarette butts by optimizing the conditions of supercritical carbon dioxide extraction. In addition, the present invention uses the discarded cigarette butts as raw materials, which can not only avoid the cigarette butts from polluting the environment, but also utilize the by-product tar after the cigarette is burned. |
