Embodiment 1

[0068] The raw material is extracted from mature seeds of fenugreek. The sample is roasted and crushed to 20 meshes. The feeding amount is 200 kg. It is added to the ultrasonic extraction tank 1, the feeding port and the discharge port are sealed, and methyl acetate 5 times the weight of the fenugreek sample is added. Esters were ultrasonically extracted at 45°C for 35 minutes. After the extraction, the air compressor was started to pressurize the ultrasonic extraction tank, and the extract was allowed to pass through the filter sieve plate at the outlet and lead to the chromatographic 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...

Embodiment 2

[0072]The fenugreek absolute oil prepared by the above method is used in cigarette shreds, the fenugreek 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 fenugreek absolute oil prepared by the present invention can effectively endow cigarettes with a maple syrup-like caramel-sweet aroma and nutty aroma, improve the aroma quantity and aroma quality of cigarette smoking, and can also cover up the miscellaneous gases of cigarette smoking , improving the comfort of cigarette smoking, which is better than that of the control sample (that is, the cigarette without adding the fenugreek absolute oil obtained by the present invention).

[0073] or,

[0074] In the cigarette filter molding process, the fenugreek absolute oil obtained in the present invention is added to triacetin by 1 wt% of the amount of plasticizer ...

Embodiment 3

[0077] During the preparation process of the electronic cigarette liquid, the fenugreek absolute oil of the present invention is added to the fenugreek-flavored electronic cigarette liquid in a proportion of 5% by weight. The results show that: the total score of the fenugreek absolute oil of the present invention is relatively high, and its advantages are mainly manifested in the characteristics of charred sweetness similar to maple syrup and the characteristics of nutty kernels, good aroma quality, and sufficient aroma; secondly, it is light in miscellaneous odors, The aftertaste is cleaner and better than that of the control sample (that is, the electronic cigarette without adding the fenugreek absolute oil obtained by the present invention).

Abstract

The invention discloses a preparation method of fenugreek absolute oil, which uses the following devices: ultrasonic extraction tank (1); chromatography column (2); air compressor (3); concentration tank (4); reverse resin column ( 5); Condenser (6); Vacuum pump (8); Solvent recovery tank (7); The steps are: ① Ultrasonic extraction of fenugreek raw material; ② Purification by chromatography column (2); ③ Concentration; ④ Passing reverse resin Column (5) purification; ⑤ decompression except ethanol, promptly obtains described fenugreek absolute. The device of the present invention can efficiently extract and purify the fenugreek absolute oil, and the obtained fenugreek absolute oil 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 fenugreek absolute and the application of the fenugreek 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 nat...
