Example Embodiment

[0067] Example 1

[0068] Extract the mature seeds of fenugreek as raw material, crush the sample to 20 mesh after roasting, and the feeding amount is 200kg, join in the ultrasonic extraction tank 1, seal the feeding port and the discharge port, and add methyl acetate of 5 times the weight of the fenugreek sample. Ester, ultrasonically extracted at 45°C for 35min, after the extraction, start the air compressor to pressurize the ultrasonic extraction tank, let the extract pass through the filter sieve plate of the discharge port 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 the vacuum pump was started at the same time to concentrate the extract until the methyl acetate was evaporated to dryness. The methyl acetate recovered after the sample was concentrated was returned to the ultrasonic extr...

[0071] Example 2

[0072]The fenugreek pure oil obtained by the above method is used in cigarette cut tobacco, and the fenugreek pure oil is added to the cigarette cut tobacco according to the ratio of 5 / 100,000 of the weight of the cut tobacco, and the cut tobacco is made into a finished cigarette for evaluation and smoking. The results show that: the fenugreek pure oil prepared by the invention can effectively impart a charred sweet aroma similar to maple syrup and a nutty aroma to cigarettes, the aroma quantity and aroma quality of cigarette smoking are improved, and the miscellaneous air of cigarette smoking can be covered. , improving the comfort of cigarette smoking, better than the control sample (ie, the cigarette without adding the fenugreek absolute oil obtained by the present invention). or,

[0073] In the cigarette filter tip forming process, the fenugreek absolute oil obtained by the present invention is added to the triacetin in an amount of 1 wt % of the amoun...

Example Embodiment

[0075] Example 3

[0076] During the preparation process of the electronic cigarette liquid, the fenugreek pure oil of the present invention is added to the fenugreek flavor electronic cigarette liquid in a proportion of 5% by weight. The results show that: the total score of the pure fenugreek oil of the present invention is higher, and its advantages are mainly manifested in that the characteristics of burnt sweetness and nut kernel aroma similar to maple syrup are outstanding, the aroma quality is good, and the aroma quantity is sufficient; The aftertaste is cleaner and better than the control sample (that is, the electronic cigarette without adding the fenugreek absolute oil obtained by the present invention).

Abstract

The invention discloses a preparing method of fenugreek absolute oil. Following devices including an ultrasonic extraction tank (1), a chromatographic column (2), an air compressor (3), a concentration tank (4), a reverse resin column (5), a condenser (6), a vacuum pump (8) and a solvent recovery tank (7) are used. The method includes the steps of firstly, conducting ultrasonic extracting on fenugreek raw materials; secondly, conducting purifying through the chromatographic column (2); thirdly, conducting concentrating; fourthly, conducting purifying through the reverse resin column (5); fifthly, conducting decompressing to remove ethyl alcohol to obtain the fenugreek absolute oil. By means of the devices, the fenugreek absolute oil can be efficiently extracted and purified, the obtained fenugreek absolute oil is used for cigarettes, electronic cigarettes or heated-non-combusted cigarettes, and the sucking comfort is effectively improved.

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...
