Problems solved by technology

At present, methods of preparing rose absolute for flavoring cigarettes mainly use methods such as solvent extraction, supercritical extraction, and molecular distillation. These methods have high production costs and low yields of absolute oil.
In addition, due to the complex composition of the existing rose extract, it is used in new rose products, which affects the smoking experience of electronic cigarettes and heat-not-burn cigarettes

Embodiment 1

[0068] The raw materials for extraction are frozen and crushed to 15 meshes of Yunnan plateau roses. The feeding amount is 200kg. The samples are crushed to 15-20 meshes and added to the ultrasonic extraction tank 1. Seal the feeding port and the discharging port, and add 5 times the weight of the rose sample. Ultrasonic extraction of methyl acetate at 45°C for 35 minutes. After the extraction, start the air compressor to pressurize the ultrasonic extraction tank, and let the extract pass through the filter sieve plate at the outlet and lead to the chromatography column for purification.

[0069] 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 extract...

Embodiment 2

[0072]The rose absolute prepared by the above method is used in cigarette shreds, the rose 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 evaluation and smoking. The results show that: the rose absolute prepared by the present invention can effectively strengthen the rose fragrance characteristic of cigarette products, the aroma quantity and aroma quality of cigarette smoking are all improved, and it can also cover up the miscellaneous gas of cigarette smoking and improve cigarette smoking. The comfort is better than that of the control sample (i.e. the cigarette that does not add the rose absolute obtained by the present invention). or,

[0073] In the cigarette filter molding process, the rose absolute obtained by the present invention is added to the triacetin according to the 1wt% amount of the plasticizer triacetin, and then the triacetin added with the ...

Embodiment 3

[0076] During the preparation process of the electronic cigarette liquid, the rose absolute of the present invention is added to the rose flavored electronic cigarette liquid in a proportion of 5% by weight. The result shows: the total score of the rose absolute of the present invention is higher, and the advantage mainly shows in that the aroma quality is good, and the amount of aroma is sufficient; secondly, it shows that the miscellaneous gas is light, and the aftertaste is cleaner, which is better than that of the contrast sample (that is, the product obtained without adding the present invention) e-cigarettes of rose absolute).

Abstract

The invention discloses a preparation method of rose absolute, which uses the following devices: 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. Rose raw material is ultrasonically extracted; 2. Purified by chromatography column (2); 3. Concentrated; 4. By reverse resin column (5) purify; 5. ethanol is removed under reduced pressure, promptly obtains described rose absolute. The device of the invention can efficiently extract and purify the rose absolute, and the obtained rose 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 essence and fragrance for tobacco, and in particular relates to a method for efficiently preparing rose absolute and the application of the rose 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 heat ...
