Embodiment 1

[0018] Embodiment 1, a method for extracting tobacco additives from Fenugreek by supercritical extraction, is characterized in that the specific steps are as follows:

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

Embodiment 2

[0021] Embodiment 2, a method for extracting tobacco additives from Fenugreek by supercritical extraction, is characterized in that the specific steps are as follows:

[0022] After crushing 6000g of dried fenugreek seeds, filter them through a 20-mesh sieve to obtain fenugreek coarse powder, then use 0.6 times the weight of fenugreek coarse powder to fully infiltrate the fenugreek coarse powder with 60% ethanol by mass, stir evenly, and put Oven, at a temperature of 50°C, bake for 5 hours and put it into a 10L supercritical extraction kettle; fill the supercritical carbon dioxide fluid as an extraction agent into the supercritical extraction kettle to 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, adding 1 times the mass percentage of fenugreek coarse powder weight to the supercritical extr...

Embodiment 3

[0024] Embodiment 3, a method for extracting tobacco additives from Fenugreek by supercritical extraction, is characterized in that the specific steps are as follows:

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

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 spices for cigarettes, in particular to a method for extracting tobacco additives from fenugreek by supercritical extraction. Background technique [0002] Fenugreek, warm in nature, bitter in taste, returns to the kidney meridian, is an annual herb of the leguminous family. Fenugreek whole herb has a strong and long-lasting coumarin smell. It can be used as medicine. It has the effects of warming kidney and yang, dispersing cold and relieving pain, moistening lung and nourishing yin, calming brain and nerves, relaxing nerves, dredging collaterals and relieving pain. It is mainly used to treat cold hernia , abdominal fullness, cold-damp beriberi, kidney deficiency, backache, impotence, etc. Fenugreek can be used as feed; tender stems and leaves can be used as vegetables, and can be dried and ground into flour and steamed as a flavor enhancer; The volatile oil contained in the whole herb is us...
