Embodiment 1

[0018] Embodiment 1, a kind of method for extracting cigarette additive from fenugreek with supercritical extraction method, it is characterized in that concrete steps are as follows:

[0019] After 600g of dried fenugreek seeds are pulverized, filter with a 20-mesh sieve to obtain fenugreek coarse powder; then fully infiltrate the fenugreek coarse powder with 0.5 times the mass percent 50% ethanol of the fenugreek coarse powder weight, stir evenly, and put it in. After baking for 1 hour at a temperature of 50 °C in an oven, put it into a 3L supercritical extraction kettle; fill the supercritical carbon dioxide fluid as an extractant into the supercritical extraction kettle and fully contact with the fenugreek coarse powder, and extract 5 hours, wherein the extraction temperature of the supercritical carbon dioxide fluid is 50 ° C, and the extraction pressure is 35 MPa; after the first extraction is completed, 0.5 times the mass percent of the fenugreek coarse powder weight is ...

Embodiment 2

[0021] Embodiment 2, a kind of method for extracting cigarette additive from fenugreek with supercritical extraction method, it is characterized in that concrete steps are as follows:

[0022] After crushing 6000g of dried fenugreek seeds, filter with a 20-mesh sieve to obtain fenugreek coarse powder, and then fully infiltrate the fenugreek coarse powder with 60% ethanol with a mass percentage of 0.6 times the weight of the fenugreek coarse powder, stir evenly, and put it in. Oven, bake for 5 hours at a temperature of 50 ° C, put into a 10L supercritical extraction kettle; fill the supercritical carbon dioxide fluid as an extractant into the supercritical extraction kettle and fully contact with the fenugreek coarse powder, and extract 10 hour, wherein the extraction temperature of the supercritical carbon dioxide fluid is 50 ° C, and the extraction pressure is 35 MPa; after the first extraction is completed, add 1 times the mass percentage of the fenugreek coarse powder to the...

Embodiment 3

[0024] Embodiment 3, a kind of method for extracting cigarette additive from fenugreek with supercritical extraction method, it is characterized in that concrete steps are as follows:

[0025] After crushing 600g of dried fenugreek seeds, filter with a 20-mesh sieve to obtain fenugreek coarse powder, then fully infiltrate the fenugreek coarse powder with 70% ethanol with a mass percentage of 0.7 times the weight of the fenugreek coarse powder, stir evenly, and put it in. Oven, bake for 2 hours at a temperature of 45 ° C, and put it into a 3L supercritical extraction kettle; use supercritical carbon dioxide fluid as an extractant and fill it into the supercritical extraction kettle to fully contact with the fenugreek coarse powder, and extract 8 hours, wherein the extraction temperature of the supercritical carbon dioxide fluid is 50 ° C, and the extraction pressure is 35 MPa; after the first extraction is completed, 0.75 times the mass percent of the fenugreek coarse powder wei...

Abstract

The invention provides a method for extracting a tobacco additive from common fenugreek seeds by adopting a supercritical extraction method. The method comprises the following steps: smashing common fenugreek seeds, filtering the smashed common fenugreek seeds to obtain common fenugreek seed coarse powder, adding 50-70% of alcohol with the weight being 0.5-2 times of that of the common fenugreek seed coarse powder into the common fenugreek seed coarse powder, carrying out baking at 50-60 DEG C for 1-5 h, adding the baked product into a supercritical extraction kettle, introducing supercritical carbon dioxide fluid into the supercritical extraction kettle, carrying out extraction for 5-10 h, adding an entrainer, carrying out extraction for 30-120 min, and separating the extract liquor obtained after the reextraction in a separation kettle, thus obtaining the common fenugreek seed tobacco additive. With the adoption of the method, the cells of the common fenugreek seeds swell, are heated and then crack, thus the aroma substances release easily, therefore, the yield of the product can be improved, in addition, the effects of enriching the tobacco fragrance, improving the quality of aroma, and masking the foreign smell are achieved, the whole process is simple and easy to master, the production is safe, and the industrial production can be completely satisfied.

Description

technical field [0001] The invention relates to the technical field of extracting flavors for cigarettes, in particular to a method for extracting additives for cigarettes from fenugreek by a supercritical extraction method. Background technique [0002] Fenugreek, warm in nature, bitter in taste, belongs to the kidney meridian, is an annual herb of the leguminous family. The whole herb of fenugreek has a strong and lasting smell of coumarin, which can be used as medicine. It has the functions of warming the kidney and helping yang, dispelling cold and relieving pain, moistening the lung and nourishing yin, calming the brain and soothing the nerves, relaxing the nerves, and dredging collaterals and relieving pain. It is mainly used for the treatment of cold hernia. , abdominal fullness, cold and damp beriberi, kidney deficiency, backache, impotence, etc. Fenugreek can be used as feed; tender stems and leaves can be eaten as vegetables, and can be sun-dried and milled into f...
