Embodiment 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 concentration to the ultrasonic...

Embodiment 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 triacetin, and then th...

Embodiment 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 method for preparing tobacco absolute. The following devices are used: an ultrasonic extraction tank (1); a chromatographic column (2); an air compressor (3); a concentration tank (4); ); Condenser (6); Vacuum pump (8); Solvent recovery tank (7); Steps are: 1. tobacco raw material is ultrasonically extracted; 2. purified by chromatography column (2); 3. concentrated; 4. passed by reverse resin column ( 5) purify; 5. decompression removes ethanol, promptly obtains described tobacco absolute. The device of the present invention can efficiently extract and purify tobacco absolute, and the obtained tobacco absolute can be used in cigarettes, electronic cigarettes or heat-not-burn cigarettes to effectively enhance and improve their smoking comfort.

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...
