Example Embodiment

[0066] Example 1

[0067] The raw material for extraction is shredded tobacco discarded in the cigarette production workshop or the tobacco redrying workshop. The feeding amount is 200kg. The sample is crushed to 15-20 mesh and added to the ultrasonic extraction tank 1. The feeding port and the discharging port are sealed. times the amount of methyl acetate, ultrasonic extraction at 45°C for 35 minutes, after the extraction, start the air compressor to pressurize the ultrasonic extraction tank, let the extract pass through the filter sieve plate at the outlet and lead to the chromatography column for purification.

[0068] After the extract passed through the chromatographic column was transferred to the concentration tank, the temperature of the concentration tank was raised to 80° C., and at the same time, the vacuum pump was started to concentrate the extract until the methyl acetate was evaporated to dryness. Return the methyl acetate recovered after the sample concentrati...

[0070] Example 2

[0071] The tobacco absolute prepared by the above method is used in cigarette shreds, the tobacco absolute is added to the shredded tobacco at a ratio of 5 / 100,000 of the weight of the shredded tobacco, and the shredded tobacco is made into finished cigarettes for smoking. The results show that: the tobacco absolute prepared by the present invention can effectively strengthen the tobacco aroma characteristics of cigarette products, the aroma quantity and aroma quality of cigarette smoking are all improved, and it can also cover the miscellaneous gas of cigarette smoking, and improve the quality of cigarette smoking. The comfort is better than that of the control cigarette (that is, the cigarette without adding the tobacco absolute obtained by the present invention). or,

[0072] In the cigarette filter molding process, the tobacco absolute obtained by the present invention is added to triacetin according to the amount of 1wt% of the amount of plasticizer tr...

[0074] Example 3

[0075] During the preparation process of the electronic cigarette liquid, the tobacco absolute of the present invention is added to the tobacco-flavored electronic cigarette liquid in a proportion of 5% by weight. The results show that: the total score of the tobacco absolute of the present invention is relatively high, and its advantages are mainly manifested in its good aroma quality, sufficient aroma quantity, and significantly improved burnt feeling of product smoking; Compared with the control sample (that is, the electronic cigarette without adding the tobacco absolute obtained in the present invention).

Abstract

The invention discloses a preparation method for tobacco absolute oil. The preparation method is performed with the following devices: an ultrasonic extraction tank (1), a chromatography column (2), an air compressor (3), a concentration tank (4), a reverse resin column (5), a condenser (6), a vacuum pump (8) and a solvent recovery tank (7). The preparation method comprises the following steps: 1,subjecting a tobacco raw material to ultrasonic extraction; 2, carrying out purification through the chromatography column (2); 3, carrying out concentration; 4, carrying out purification through thereverse resin column ( 5); and 5, carrying out decompressing to remove ethanol so as to obtain the tobacco absolute oil. The devices provided by the invention can realize highly-efficient extractionand purification of the tobacco absolute oil; and the tobacco absolute oil obtained by using the preparation method provided by the invention is used in cigarettes, electronic cigarettes or heat-not-burn cigarettes, and effectively enhances and improves the suction comfort of the cigarettes, the electronic cigarettes and the heat-not-burn cigarettes.

Description

technical field [0001] The invention belongs to the field of preparation of flavors and fragrances for tobacco, and in particular relates to a method for efficiently preparing tobacco absolute and the application of the tobacco absolute in flavoring cigarettes, electronic cigarettes and heat-not-burn cigarettes. Background technique [0002] Cigarette flavoring is the core technology to enhance the style of cigarettes. Especially in recent years, the continuous promotion of tar reduction and harm reduction work in the tobacco industry has gradually reduced the amount of tar released in cigarettes, and with it, the aroma and taste of cigarettes have also decreased. , which often requires means of flavoring to ensure and improve the sensory quality of cigarettes, and to satisfy consumers' pursuit of the aroma and taste of cigarettes. In addition, with the development of new tobacco products such as e-cigarettes and heat-not-burn cigarettes, new tobacco products also have a str...
