Description
Technical field
The present invention relates to a kind of preparation method of cigarette absolute oil, specifically a kind of cigarette preparation side of tealeaves absolute oil
Method.
Background technology
Essentially from the bud-leaf of plant of theaceae tea, it has become people daily to tealeaves as the plant of medicine-food two-purpose
The indispensable means of livelihood in life.China be also in the world tealeaves cultivate, make, drinking earliest country.Tea aroma
And its research of composition has the history of nearly 100 years so far, according to pertinent literature, more than 600 kinds and tealeaves have been identified at present
The related volatile materials of fragrance, although different teas kinds has different Type of aroma, but it is respectively provided with certain thing
Matter basis, also the difference just because of the balance between all kinds of fragrance and various fragrance component ratios forms the perfume (or spice) of different teas
Gas feature.
Knowable to current documents and materials report, most of tea extract with tealeaves as raw material, by after enzymolysis processing,
Refilter, concentrate and prepare tea extract.The extract fragrance that the method is obtained not enough enriches, in lifting cigarette flavor matter,
Improve oral cavity pleasant impression and assign cigarette style characteristic aspect and go back Shortcomings, and technique is complex, reappearance is not good enough, production week
Phase is long.
Also there is patent to disclose the method that essence spice for cigarette is prepared using tealeaves, such as Patent No. at present：
ZL201010282751.9 is first passed through carries out steam distillation to tea raw material, then carries out post adsorption treatment to distillate, obtains
Tealeaves volatility causes perfumery.Due to the means using high temperature distillation, thermal sensitivity aroma component is subject to the method in easily causing tealeaves
Destruction, and then have influence on the odor characteristic of final products；Patent No.：ZL201210181152.7 tea raw materials are through deproteinization
After treatment, it is applied in reconstituted tobacoo.Though the method is processed through deproteinization, cellulose, colloid for wherein still containing etc.
Material can bring certain negative effect to the suction mouthfeel of reconstituted tobacoo；Patent No.：ZL201510472142.2 tealeaves is former
After material is extracted, successively through petroleum ether, ethyl acetate and extracting n-butyl alcohol after, then through normal-phase chromatography post separation and high performance liquid chromatography
Prepare, finally give tobacco humectant.The method technique is cumbersome, and product yield is low, and consumption of organic solvent is big, easily causes pollution.
The content of the invention
The present invention is exactly to overcome present in above-mentioned technology of preparing not enough, there is provided a kind of cigarette preparation side of tealeaves absolute oil
Method, the method is simple efficiently, energy-conserving and environment-protective, and tealeaves absolute oil gives off a strong fragrance, and has preferable application effect in cigarette.
The technical scheme is that：A kind of cigarette preparation method of tealeaves absolute oil, comprises the following steps：
(1) tealeaves is crushed to 10-20 mesh, prepares tea raw material, it is standby.
(2) tea raw material after being processed through step (1), adds the 2-6 times of 10%-50% ethanol water measured, in 55-
Dynamic countercurrent is extracted 2 times under the conditions of 70 DEG C, each 1-2h, after extraction terminates, merges extract solution twice.
(3) by the extract solution after merging under the conditions of -0.090MPa~-0.095MPa, 50 DEG C -55 DEG C, it is concentrated under reduced pressure
To tealeaves concentrate.
(4) to the ethyl acetate solution that its 0.8-1.2 times of weight is added in tealeaves concentrate, being sufficiently mixed is carried out for the first time
Liquid-liquid extraction, stratification obtains ethyl acetate phase.
(5) in the water phase after being processed through step (4), extraction 3-6 times is repeated, its 0.2-0.5 times of weight is added every time
Ethyl acetate solution, after stratification, collect ethyl acetate phase.
(6) ethyl acetate phase after merging is carried out depressurizing dense in -0.090MPa~-0.095MPa, 30 DEG C of -35 DEG C of conditions
It is reduced to without ethyl acetate taste, prepares tealeaves medicinal extract.The ethyl acetate that concentration is distilled out can be recycled.
(7) to the absolute ethyl alcohol that its 4-6 times of weight is added in tealeaves medicinal extract, 30min is stirred, is stood under the conditions of 3-5 DEG C
6-12h。
(8) precipitation solution for obtaining step (7), using 100nm ceramic membrane filters, half flowing is concentrated under reduced pressure into by membrane filtration liquid
Paste, as cigarette tealeaves absolute oil.
Further, in the step (3) tealeaves concentrate relative density 1.055 ± 0.0080.
Further, condition concentrated under reduced pressure in the step (8) is：Pressure：- 0.090MPa~-0.095MPa, temperature
It is 40 DEG C -45 DEG C.
It is an advantage of the invention that：The method is simple efficiently, energy-conserving and environment-protective, and the tealeaves absolute oil fragrance for preparing is true to nature strong,
It is added in cigarette, cigarette perfume can be enriched, lift aroma quality, improves oral cavity pleasant impression, and assign cigarette peculiar style and features.

Aroma quality is risen, improves oral cavity pleasant impression, and assign cigarette idiosyncrasy feature.Specific smoking result such as following table：
Cigarette green tea absolute oil is smoked panel test effect table
In the effect above table, aroma quality effect is better, and score value is higher, 18 points of full marks；Perfume quantity effect more good grades are higher,
15 points of full marks；Smoke behavior is better, and score value is higher, 10 points of full marks；The miscellaneous fewer score value of gas is higher, 12 points of full marks；Smaller point of excitant
It is worth higher, 20 points of full marks；Pleasant impression is more comfortable, and score value is higher, 25 points of full marks, amounts to 100 points of full marks.
Be can be seen that come the five kinds of different cigarettes that with the addition of the preparation in the present invention are used with cigarette by the effect above contrast table
Substantially, aroma quality lifting, perfume quantity increases cigarette odor characteristic after green tea absolute oil, and miscellaneous gas and excitant are reduced, and pleasant impression is more easypro
It is suitable.
The detailed description of specific embodiments of the present invention is the foregoing is only, the present invention is not limited with this, it is all at this
Any modification, equivalent and improvement for being made in the mentality of designing of invention etc., should be included in protection scope of the present invention it
It is interior.
