Problems solved by technology

[0004] At present, coffee extracts are used as tobacco additives. The main products are extracts, tinctures, absolutes, etc. Traditional coffee extract preparation methods mainly use methods such as solvent extraction, supercritical extraction, and molecular distillation. The production costs of these methods High, low net oil rate
In addition, the existing coffee extract is used in new tobacco products due to its complex composition, which affects the smoking experience of electronic cigarettes and heat-not-burn cigarettes

Embodiment 1

[0069] The raw material used for extraction is Yunnan arabica coffee, which is fermented and roasted, and crushed to 15 meshes. The feeding amount is 200 kg. It is added to the ultrasonic extraction tank 1, the feeding port and the feeding port are sealed, and methyl acetate, which is 5 times the weight of the coffee sample, is added. 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.

[0070] 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 extr...

Embodiment 2

[0073] The coffee absolute prepared by the above method is used in cigarette shreds, the coffee absolute is added to the cigarette shreds 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 coffee absolute prepared by the present invention can effectively endow cigarettes with elegant and natural coffee-specific toasted aroma and nutty aroma, improve the amount and quality of aroma smoked by cigarettes, and can also cover up miscellaneous gases smoked by cigarettes , to improve the comfort of cigarette smoking, which is better than that of the control sample (i.e. the cigarette without adding the coffee absolute obtained by the present invention).

[0074] or,

[0075] In the cigarette filter forming process, the coffee absolute obtained by the present invention is added to the triacetin according to the 1wt% amount of the plasticizer triacetin, and then the triacetin ad...

Embodiment 3

[0078] During the preparation process of the electronic cigarette liquid, the coffee absolute of the present invention is added to the coffee-flavored electronic cigarette liquid in a proportion of 5% by weight. The result shows: the total score of the coffee absolute of the present invention is higher, and the advantage is mainly shown in good aroma quality and sufficient aroma quantity; secondly, it is light in miscellaneous gas, and the aftertaste is cleaner, which is better than that of the control sample (that is, the coffee obtained without adding the present invention) e-cigarettes with coffee absolute).

Abstract

The invention discloses a method for preparing coffee 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); The steps are: 1. Ultrasonic extraction of coffee raw material; 2. Purification by chromatographic column (2); 3. Concentration; 5) purify; 5. decompression removes ethanol, promptly obtains described coffee absolute. The device of the present invention can efficiently extract and purify coffee absolute, and the obtained coffee 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 coffee absolute and the application of the coffee 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 advancement of tobacco tar reduction and harm reduction has gradually reduced the amount of tar released in cigarettes, and the accompanying reduction in cigarette aroma and taste. This often requires the use of flavoring methods to ensure and improve the sensory quality of cigarettes, so as 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, there is also a strong demand for new types of natural ...
