Description
Technical field
The present invention relates to plant extract and application thereof, be specifically related to a kind of Extractive and preparation method thereof and the application of this extract in cigarette.
Background technology
Laoyin tea is the xylophyta of Lauraceae, containing Multiple components, as materials such as amino acid, mineral element, vitamin C, vitamin B1, vitamin B2, flavonoids, Polyphenols, caffeines.The record such as Compendium of Material Medica has " cough-relieving, eliminate the phlegm, relieving asthma, relieve summer heat and quench one's thirst ".
For the extraction of Laoyin tea, in traditional handicraft, generally adopt water, alcohol extracts Laoyin tea, then after carrying out separation and purification, concentrate drying obtains the method for extract.But the Extractive active constituent content that the method obtains is low, is unsuitable for industrializing implementation.And the Extractive obtained in traditional handicraft, be dried powder, be also unsuitable for long period preservation.How to improve extraction process, to improve the content of the Extractive active ingredient obtained, be the direction that people make great efforts.On the other hand, present stage, because the pharmacological action of Laoyin tea, the domestic application study about Laoyin tea mainly concentrates on medicines and health protection field, and the application in cigarette has no relevant report.
Summary of the invention
The object of the invention is for described defect above, providing a kind of larger degree of convergence can improve the Extractive obtaining active constituent content in Extractive.
Another object of the present invention is to provide a kind of preparation method and the application of this extract in cigarette of Extractive.
The object of the invention is to be achieved by the following technical programs.
A preparation method for the extract of Laoyin tea, comprises the following steps successively:
1. pretreatment: Laoyin tea raw material to be extracted is dried under 40 ~ 70 DEG C of conditions, and the Laoyin tea powder being crushed to that granularity is 150-420 μm;
2. ultrasonic wave extracts: 8 ~ 15 times of water adding Laoyin tea powder weight, carries out ultrasonic extraction 15 ~ 30min, obtains extract;
3. ethanol removal of impurities: by step 2. in extract filter, filtrate carrying out is evaporated to 1 times of Laoyin tea powder quality, adds ethanol and makes alcohol content in concentrate reach 50 ~ 75%, stir, less than 4 DEG C static 8 ~ 24h;
4. UF membrane: by step 3. in mixed liquor filter, filtrate by hollow-fibre membrane, collects permeate;
5. concentrate: by step 4. in the permeate that obtains carry out reduced pressure concentration, described concentrated after thick solution be Extractive.
Preferably, described step 2. middle ultrasonic extraction condition is ultrasonic power 500 ~ 1000W, ultrasonic frequency 20KHz ~ 60KHz, and temperature is room temperature ~ 55 DEG C.
Preferably, described step 4. in hollow-fibre membrane molecular weight be 3k ~ 10k dalton.
A kind of Extractive, adopts said method to prepare.
The application of Extractive of the present invention in cigarette: the nontoxic organic solvent had no irritating odor of described Extractive is diluted, extension rate is 10-15 times; Before preparing cigarette, described Extractive dilution is sprayed at cured tobacco leaf surface according to the mass ratio of 0.1%-1%.
Described organic solvent is propane diols, sorbierite, xylitol or glycerine, or wherein any mixed liquor of more than two kinds.
The invention has the beneficial effects as follows: the present invention compared with prior art, employing ultrasonic extraction, membrane separation technique means prepare Extractive, active ingredient in Laoyin tea can be extracted comparatively complete, guarantee the content of active ingredient in Extractive.The extracting method of Laoyin tea of the present invention, can improve the purification effect in production process, improves the product quality extracting product, makes in whole production process efficient, is suitable for industrializing implementation.On the other hand, the Extractive that preparation method of the present invention obtains is applied in cigarette preparation, easy to use, and greatly can improve the interior quality of cigarette, assorted gas is reduced, and exhaust gas volumn increases, and improves mouthfeel, drastically increases the interior quality of cigarette.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in further details.
embodiment 1.
Accurately take 200g Laoyin tea, 45 DEG C of oven dry, and be crushed to the meal that granularity is 200um, add 1.6kg water, ultrasonic wave extracts 20min, ultrasonic power 500W, ultrasonic frequency 20KHz, constant temperature 35 DEG C, after extracting liquid filtering, be evaporated to 400g, add ethanol and make alcohol content in concentrate reach 50%, stir, less than 4 DEG C static 8 h.Filtered by mixed liquor, filtrate is the daltonian hollow-fibre membrane of 4k through molecular cut off again, collects permeate, is evaporated to thick solution, is Extractive I.
embodiment 2.
Accurately take 200g Laoyin tea, 55 DEG C of oven dry, and be crushed to the meal that granularity is 300um, add 2.4kg water, ultrasonic wave extracts 10min, ultrasonic power 800W, ultrasonic frequency 40KHz, constant temperature 45 DEG C, after extracting liquid filtering, be evaporated to 400g, add ethanol and make alcohol content in concentrate reach 60%, stir, less than 4 DEG C static 16 h.Filtered by mixed liquor, filtrate is the daltonian hollow-fibre membrane of 6k through molecular cut off again, collects permeate, is evaporated to thick solution, is Extractive II.
embodiment 3.
Accurately take 200g Laoyin tea, 65 DEG C of oven dry, and be crushed to the meal that granularity is 400um, add 3.0kg water, ultrasonic wave extracts 30min, ultrasonic power 1000W, ultrasonic frequency 60KHz, constant temperature 55 DEG C, after extracting liquid filtering, be evaporated to 400g, add ethanol and make alcohol content in concentrate reach 70%, stir, less than 4 DEG C static 24 h.Filtered by mixed liquor, filtrate is the daltonian hollow-fibre membrane of 8k through molecular cut off again, collects permeate, is evaporated to thick solution, is Extractive III.
Experimental test: Extractive I, II, III obtained in above-described embodiment 1,2 and 3 is all diluted to 10 times with 50% propylene glycol solution, be then sprayed at the middle-grade blank of same (non-flavoring and casing) flue-cured tobacco pipe tobacco surface, addition is 0.5% of pipe tobacco.Subsequent treatment cigarette process routinely carries out, namely after spraying the dilution of Extractive, by flue-cured tobacco tobacco storage 4 hours, then through chopping, dry silk, perfuming, storage silk, cigarette and packaging process and make cigarette finished product.The group of smokeing panel test be made up of 8 people to smoke panel test contrast to above-mentioned sample respectively, and the overall organoleptic's result of the test obtained is as shown in the table.Wherein, the interior quality of blank sample is all set as 0, improve to some extent (as assorted gas lowers, exhaust gas volumn increases, and mouthfeel is improved) relative to blank sample interior quality, then mutually deservedly just divide, score value is higher, and it is better to improve; Decrease (as assorted gas increases, exhaust gas volumn reduces, and mouthfeel reduces) relative to blank sample interior quality, then mutually deserved negative point, negative point lower, and it is poorer to improve.
| Sample | Assorted gas improves | Exhaust gas volumn is improved | Mouthfeel is improved |
| Blank sample | 0 | 0 | 0 |
| Extractive I | 2 | 3 | 3 |
| Extractive II | 2 | 2 | 2 |
| Extractive III | 1 | 1 | 1 |
From above table, relative to the cigarette of blank sample, the cigarette foreign gas of the Extractive that tobacco leaf increases obviously improves, and exhaust gas volumn increases, and mouthfeel is improved obviously, and cigarette interior quality is all improved.
Above content is in conjunction with concrete preferred embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, make some substituting or obvious modification without departing from the inventive concept of the premise, and performance or purposes identical, all should be considered as belonging to protection scope of the present invention.
