Example Embodiment

[0024] Example 1

[0025] Under the conditions of a roasting temperature of 180°C and a roasting time of 3.5h, the selected coptis is roasted, crushed, and filtered with a 40-mesh sieve for use. Put the above-mentioned coptis and 6 times the weight of the above-mentioned 50% ethanol solution into an extraction tank for reflux extraction. The extraction temperature is 60° C., and the extraction time is 4 hours. After the extraction, the extraction liquid a1 and the residue b1 are separated. Add 6 times the weight of the residue b1 in 50% ethanol aqueous solution to the residue b1, and perform reflux extraction again. The extraction temperature is 60° C., and the extraction time is 4 hours. After the extraction, the extraction solution c1 and the residue d1 are separated. After mixing the obtained extract a1 and the extract c1, coarse filtration was performed with a 160-mesh screen to obtain a crude filtrate of Rhizoma Coptidis. The obtained rough filtrate of Rhizoma Rhizoma Copti...

[0027] Example 2

[0028] Under the conditions of a roasting temperature of 200°C and a roasting time of 3 hours, the selected Coptis chinensis was roasted, crushed, and filtered with a 40-mesh sieve for use. The above-mentioned coptis and a 60% ethanol aqueous solution of 6 times the weight of the above-mentioned coptis were put into an extraction tank for reflux extraction. The extraction temperature was 65° C. and the extraction time was 4 hours. After the extraction, the extraction solution a2 and the residue b2 were separated. Add 6 times the weight of the residue b2 60% ethanol aqueous solution to the residue b2, and perform reflux extraction again. The extraction temperature is 65° C., and the extraction time is 4 hours. After the extraction, the extraction solution c2 and the residue d2 are separated. After mixing the obtained extract a2 and the extract c2, coarse filtration was performed with a 180-mesh sieve to obtain a crude filtrate of Rhizoma Coptidis. The obtained ...

[0030] Example 3

[0031] Under the conditions of a roasting temperature of 250°C and a roasting time of 2.5h, the selected Coptis chinensis was roasted, crushed, and filtered with a 50-mesh sieve for use. The above-mentioned coptis and 8 times the weight of the above-mentioned coptis in 70% ethanol aqueous solution were put into an extraction tank for reflux extraction, the extraction temperature was 70° C., and the extraction time was 5 hours. After the extraction, the extraction liquid a3 and the residue b3 were separated. A 70% ethanol aqueous solution of 8 times the weight of the residue b3 was added to the residue b3, and reflux extraction was performed again at an extraction temperature of 70° C. and an extraction time of 5 hours. After the extraction, the extraction solution c3 and the residue d3 were separated. After mixing the obtained extract a3 and the extract c3, coarse filtration was performed with a 200-mesh sieve to obtain a crude filtrate of Rhizoma Coptidis. Th...

Abstract

The invention discloses a preparation method for tobacco coptis chinensis extract. The preparation method comprises the following steps of: parching and crushing selected coptis chinensis, and filtering the parched and crushed coptis chinensis with a screen; adding an ethanol aqueous solution, weight of which is 4-12 times that of corresponding coptis chinensis, into the coptis chinensis to carry out reflux extraction, and separating the solution after the extraction is ended, thereby obtaining an extracting solution a and residues b; carrying out reflux extraction after adding the ethanol aqueous solution, weight of which is 4-12 times that of corresponding residues, into residues b, and separating the solution after the extraction is ended, thereby obtaining an extracting solution c and residues d; mixing the extracting solution a with the extracting solution c to obtain a mixed solution, and firstly carrying out rough filtration on the mixed solution by use of the screen; carrying out separation treatment on obtained coptis chinensis rough filtrate by use of a ceramic membrane; then, carrying out concentration treatment on the obtained coptis chinensis rough filtrate; and finally, separating and purifying the coptis chinensis rough filtrate by utilizing a molecular distillation technology, wherein obtained light molecular components are tobacco coptis chinensis extract. The preparation method has the advantages that: the prepared tobacco coptis chinensis extract is vivid in fragrance, and is sprayed on cut tobaccos to prepare cigarettes, so that the fragrance amount and the smoke concentration can be increased, the mouthfeel is improved, salivation is promoted and aftertaste is sweet.

Description

technical field [0001] The invention relates to the technical field of preparing an extract for tobacco, in particular to a preparation method of an extract of Coptidis rhizome for tobacco. Background technique [0002] Molecular distillation is a distillation method operated under high vacuum. At this time, the mean free path of vapor molecules is greater than the distance between the evaporation surface and the condensation surface, so that the difference in evaporation rate of each component in the feed liquid can be used to optimize the liquid mixture. to separate. [0003] The short-path still consists of an externally heated vertical cylinder, a central condenser located in it, and a wiper that rotates between the still and the condenser. The distillation process is: the material is added from the top of the evaporator, and the material liquid distributor on the rotor distributes it continuously and evenly on the heating surface, and then the film scraper scrapes the ...
