Embodiment 1

[0025] Under the conditions of a roasting temperature of 180°C and a roasting time of 3.5 hours, the selected Coptis chinensis was roasted, crushed, and filtered through a 40-mesh sieve for later use. Put the above-mentioned Coptidis rhizome and 50% ethanol aqueous solution which is 6 times the weight of the above-mentioned Coptidis rhizome into the extraction tank for reflux extraction, the extraction temperature is 60°C, the extraction time is 4h, and the extraction liquid a1 and residue b1 are separated after the extraction is completed. Add 50% ethanol aqueous solution of 6 times the weight of residue b1 to residue b1, and carry out reflux extraction again, the extraction temperature is 60°C, and the extraction time is 4h. After the extraction is completed, extract c1 and residue d1 are separated. After the obtained extract a1 and extract c1 were mixed, coarse filtration was performed with a 160-mesh sieve to obtain a coarse filtrate of Coptis rhizome. The obtained coptis ...

Embodiment 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 through a 40-mesh sieve for later use. Put the above-mentioned Coptidis rhizome and 60% ethanol aqueous solution which is 6 times the weight of the above-mentioned Coptidis rhizome into the extraction tank for reflux extraction, the extraction temperature is 65°C, and the extraction time is 4h. After the extraction is completed, the extraction liquid a2 and the residue b2 are separated. Add 60% ethanol aqueous solution of 6 times the weight of the residue b2 to the residue b2, carry out reflux extraction again, the extraction temperature is 65° C., and the extraction time is 4 hours. After the extraction is completed, the extract c2 and the residue d2 are separated. After mixing the obtained extract a2 and extract c2, perform coarse filtration with a 180-mesh sieve to obtain a Coptis rhizome crude filtrate. The obtained...

Embodiment 3

[0031] Under the condition that the roasting temperature is 250°C and the roasting time is 2.5 hours, the selected Coptis chinensis is roasted, crushed, and filtered through a 50-mesh screen for later use. Put the above-mentioned Coptidis rhizome and 70% ethanol aqueous solution which is 8 times the weight of the above-mentioned Coptidis rhizome into the extraction tank for reflux extraction, the extraction temperature is 70°C, the extraction time is 5h, and the extraction solution a3 and residue b3 are separated after the extraction is completed. Add 8 times the weight of residue b3 in 70% ethanol aqueous solution to residue b3, carry out reflux extraction again, extraction temperature is 70°C, extraction time is 5h, after extraction, separate and obtain extract c3 and residue d3. After mixing the obtained extract a3 and extract c3, perform coarse filtration with a 200-mesh sieve to obtain a Coptis rhizome crude filtrate. The obtained coptis rhizome crude filtrate is separate...

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 ...
