Embodiment 1

[0022] The tobacco leaves used were Yuxi Hongda B2F, and the tobacco leaf samples were dried at 70°C and crushed to 80 mesh. Take the pulverized tobacco powder, use dimethyl ether as the subcritical extractant, glycerol triacetate as the entrainer, and carry out subcritical extraction at a temperature of 30°C and an extraction pressure of 2.5Mpa; the extractant dimethyl ether The amount is 10 times the weight of the smoke. The entraining agent triacetin consumption is 4 times of the tobacco weight. After the extraction is completed, the extraction mixture enters the separation tank, and the extraction solvent is separated by the principle of reduced-pressure evaporation to obtain a glycerol triacetate extract rich in tobacco aroma components. After recovery of dimethyl ether, the triacetin extract rich in tobacco aroma components was diluted 10 times with triacetin to make it fully dissolved, then cooled to room temperature, transferred to -15°C refrigerator for 10 hours, and...

Embodiment 2

[0024] The tobacco leaves used were Dali K326, and the tobacco leaf samples were dried at 75°C and crushed to 90 mesh. Take the pulverized tobacco powder, use dimethyl ether as the subcritical extractant, glycerol triacetate as the entrainer, and carry out subcritical extraction at a temperature of 25°C and an extraction pressure of 2.8Mpa; the extractant dimethyl ether The amount is 12 times the weight of tobacco. The entraining agent triacetin consumption is 5 times of the tobacco weight. After the extraction is completed, the extraction mixture enters the separation tank, and the extraction solvent is separated by the principle of reduced-pressure evaporation to obtain a glycerol triacetate extract rich in tobacco aroma components. After recovery of dimethyl ether, the triacetin extract rich in tobacco aroma components was diluted 10 times with triacetin to make it fully dissolved, then cooled to room temperature, transferred to -18°C refrigerator for 10 hours, and separat...

Embodiment 3

[0026] The tobacco leaf used was Honghe Yunyan-87, and the tobacco leaf samples were dried at 78°C and crushed to 95 mesh. Take the pulverized smoke powder, use dimethyl ether as the subcritical extractant, glycerol triacetate as the entrainer, and carry out subcritical extraction at a temperature of 28°C and an extraction pressure of 2.9Mpa; the extraction agent dimethyl ether The amount is 15 times the weight of tobacco. The entraining agent triacetin consumption is 5 times of the tobacco weight. After the extraction is completed, the extraction mixture enters the separation tank, and the extraction solvent is separated by the principle of reduced-pressure evaporation to obtain a glycerol triacetate extract rich in tobacco aroma components. After recovery of dimethyl ether, the triacetin extract rich in tobacco essential aroma components was diluted 8 times with triacetin to make it fully dissolved, then cooled to room temperature, transferred to -20°C for 8 hours, and cent...

Abstract

The invention discloses a preparing method of a cigarette filter stick additive. According to the cigarette filter stick additive, tobacco leaves are adopted as a raw material, and the method comprises the following steps of 1, preparing the raw material, wherein the tobacco leaves are dried at 50-80 DEG C, and are smashed to reach the mesh number of 50-100; 2, conducting subcritical extraction, wherein the smashed tobacco leaf powder in the step 1 is extracted at 0-50 DEG C and 0.5-3.0 MPa with dimethyl ether being an extraction agent and triacetin being a cosolvent; 3, preparing the filter stick additive, wherein dimethyl ether in the step 2 is recycled, and the obtained triacetin solution containing tobacco leaf extract is the cigarette filter stick additive. The invention further discloses application of the cigarette filter stick additive obtained through the preparing method in cigarette products.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and in particular relates to a method for subcritical extraction to prepare tobacco aroma components and its application in cigarettes. Background technique [0002] Nicotiana belongs to Solanaceae, tobacco annual or limited perennial herbaceous plants, among which tobacco N.tabacum L. is the most widely cultivated, and its mature leaves are important raw materials for the cigarette industry and a crop with high economic value. Although smoking is widely recognized as harmful to health, tobacco still has a strong appeal to thousands of consumers. In addition to the addictive properties of nicotine, the rich flavor substances in tobacco also play an important role. However, with the continuous improvement of consumers' health awareness, cigarette products must pay more attention to the requirements of low harm, safety, health and other aspects. During the innovation process of new cigarette pr...
