Embodiment 1

[0068] Red dates produced in Shule, Xinjiang are used as raw materials for extraction. After the red dates are pitted, they are dried, crushed to 18 mesh, and the feeding amount is 200kg. They are added to the ultrasonic extraction tank 1, and the feeding port and the discharging port are sealed. 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 extraction tank 1, an...

Embodiment 2

[0072] The jujube absolute oil prepared by the above method is used in shredded cigarette tobacco, the jujube absolute oil 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 evaluation and smoking. The results show that the jujube absolute oil prepared by the present invention can effectively strengthen the jujube aroma characteristic of cigarette products, the aroma quantity and aroma quality of cigarette smoking are all improved, and the miscellaneous gas of cigarette smoking can also be covered up, and the quality of cigarette smoking can be improved. Comfortability is better than that of the control sample (i.e. the cigarette without adding the jujube absolute oil obtained by the present invention). or,

[0073] In the cigarette filter forming process, the jujube absolute oil obtained by the present invention is added to the triacetin by 1 wt% of the amount of the pla...

Embodiment 3

[0076] During the preparation process of the electronic cigarette liquid, the jujube absolute oil described in the present invention is added to the jujube-flavored electronic cigarette liquid at a ratio of 5% by weight. The results show that: the total score of jujube absolute oil of the present invention is higher, and the advantages are mainly reflected in the characteristic characteristic of roasted sweetness of jujube, good aroma quality, and sufficient aroma; secondly, it is light in miscellaneous gas, and the aftertaste is cleaner, which is better than Control sample (that is, the electronic cigarette without the jujube absolute oil obtained in the present invention).

Abstract

The invention discloses a preparation method of red jujube clean oil, which uses the following devices: an ultrasonic extraction tank (1); a chromatographic column (2); an air compressor (3); a thickening tank (4); a reverse resin column (5); a condenser (6); a vacuum pump (8); a solvent recovery tank (7). The method includes the steps of (1) ultrasonic extraction of red jujube raw material; (2),purifying by chromatographic column; (3); concentration; (4) purifying by a reverse resin column; (5) removing ethanol under reduced pressure to obtain the pure red jujube oil. The device of the invention can efficiently extract and purify the red jujube clean oil, and the obtained red jujube clean oil can be used in cigarette, electronic cigarette or heated non-combustible cigarette, so as to effectively improve and improve the smoking comfort of the cigarette.

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 jujube absolute and the application of the jujube 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 ...
