Abstract
The invention relates to the technical field of preparation of tobacco extracts, and discloses a preparation method and application of a deproteinized tobacco extract. The method comprises the following steps: smashing chopped tobacco into tobacco powder; mixing the tobacco powder with water, and adding alkali for regulating the pH to 8-10; separating the mixture to obtain a precipitate A and a supernate A; regulating the pH of the supernate to 3-5, separating to obtain a precipitate B and a supernate B, and removing the precipitate B; concentrating the supernate B, mixing with the precipitate A, and adding alkali for regulating the pH to 7-8 to obtain the deproteinized tobacco extract. By adopting preparation method of the deproteinized tobacco extract, proteins in tobacco can be removed completely, and the tobacco extract with low protein content and a good flavoring effect can be obtained. By adding the deproteinized tobacco extract prepared by using the preparation method into cut tobacco in the mass ratio of 0.2-2 percent, the flavor quality and flavor amount of prepared cigarettes can be enhanced greatly while irritation to the mouth and throat is not increased.
Description
Technical field
The present invention relates to prepare the technical field of tobacco extract, more specifically, relate to a kind of preparation method and application of deproteinized tobacco extract.
Background technology
Tobacco extract obtains for raw material is prepared mainly with smashed tobacco powder, fragment etc., its increase nature this perfume of tobacco and old cigarette note, increasing smoke concentration, and cigarette perfume harmony aspect have irreplaceable effect, no matter its product directly applies to cigarette or allocates other balsamic base product aspects, have a large amount of application.Numerous flavouring essence for tobaccos produce family even cigarette enterprise all developed the various tobacco extracts of different material, different extraction processes.
Protein tobacco is along with growing of tobacco builds up, and as the exploitation of edible protein resource, tobacco protein has its positive role, for the impact of tobacco leaf sucking quality, needs to should be regarded as a different matter.Cured tobacco leaf protein content after ovennodulation is generally in 8% left and right.In tobacco product, focus on especially tobacco aroma and inhale taste, and protein content is too high, fragrance and jealous variation, produce acid, bitter taste and excitant.
The method of removing protein tobacco in existing tobacco extract technique is mainly enzymatic isolation method and chemical method, enzymolysis can decompose protein tobacco, enzymolysis liquid adds in cigarette can improve smoking property of cigarette quality, play the effect of flavouring and increasing flue gas concentration, but in the amino acid pipe tobacco combustion process that enzymolysis produces, can decompose and produce ammonia, and the volatilization of ammonia is one of irritating source of flue gas; Chemical method utilizes Maillard reaction principle, adds sugar and proteins react, but more difficult control course of reaction, and reaction is not thorough.
Existing Chinese patent notification number is that CN102894467A discloses a kind of immobilised enzymes preparation that utilizes and in conjunction with acetic acid bacteria fermentation, prepares the method for tobacco extract, to obtain and process product with immobilization processing with enzyme preparation tobacco extract raw material, recycling acetic acid bacteria fermentation process product obtains tunning, then by tunning concentration, thereby obtain tobacco extract.This method can reduce the content of starch in tobacco extract, protein, cellulose, lignin and pectic substance, higher to specification requirement, with traditional native enzyme molecular proportion, curing enzyme is relatively more fragile, wayward, and the time that this method needs is long, and the scope of application of tobacco extract is still had to certain limitation.
Summary of the invention
The preparation method who the object of this invention is to provide a kind of deproteinized tobacco extract, can remove the protein in tobacco comparatively up hill and dale, thereby obtain, protein content is low, the good tobacco extract of perfuming effect.
Another technical problem that will solve of the present invention is to provide the application aspect tobacco production of deproteinized tobacco extract that described preparation method obtains.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
The preparation method that a kind of deproteinized tobacco extract is provided, comprises the following steps:
S1. smashed tobacco powder is pulverized and obtained tobacco powder;
S2. the tobacco powder in S1 is mixed with water, and add alkali to regulate pH to 8 ~ 10;
S3. the mixture in S2 is carried out to separation, be precipitated A and supernatant A;
S4. after the supernatant A in S3 being regulated to pH to 3 ~ 5, carry out separation, be precipitated B and supernatant B, remove deposit B;
S5. after the supernatant B in S4 being concentrated, mix with the deposit A obtaining in S3, then add alkali to regulate pH to 7 ~ 8, obtain deproteinized tobacco extract.
Preferably, in S1, in the environment of 50 ~ 60 ℃, the moisture of smashed tobacco powder is dried to 4 ~ 7%, then the smashed tobacco powder after drying is pulverized, cross 100 mesh sieves, obtain tobacco powder;
Preferably, in S2, by tobacco powder and water according to the mass ratio mix and blend 1h of 0.5 ~ 1:10 after, add alkali to regulate pH to 8 ~ 10.Preferably, described tobacco powder mixes according to the mass ratio of 1:10 with water;
Preferably, in S3, the mixture that adopts centrifuge to obtain step S2 carries out separation, and wherein, the rotating speed of described centrifuge is 3000 ~ 5000rpm, and centrifugation time is 20min;
Preferably, in S4, the mixture that adopts centrifuge to obtain step S3 carries out separation, and wherein, the rotating speed of described centrifuge is 3000 ~ 5000rpm, and centrifugation time is 20min;
Preferably, in S4, adopt citric acid that supernatant A is regulated to pH to 3 ~ 5;
Preferably, in S5, adopt film scraper plate instrument that supernatant B is concentrated into 1/10 ~ 1/5 of original volume;
Preferably, in the method for the invention, regulating pH alkali used is NaOH.
The invention provides the deproteinized tobacco extract that described preparation method prepares.
The present invention provides the application of described deproteinized tobacco extract aspect tobacco production simultaneously, makes cigarette after specifically described deproteinized tobacco extract being put on to pipe tobacco.The deproteinized tobacco extract that uses preparation method of the present invention to make adds after pipe tobacco, especially in 0.2 ~ 2% the ratio that applies of tobacco quality, put on the cigarette of making after pipe tobacco, its fragrance matter and perfume quantity are all greatly improved, and oral cavity throat excitement does not increase.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention, through science design step by step, uses the pH value of the mixture of alkali conditioning tobacco powder and water by S2 after tobacco powder mixes by suitable ratio with hydromining, object is with alkali, the protein in tobacco powder to be dissolved out; Through S3, process again, obtain in deposit A and contain non-alkali solubility tobacco powder composition, standby; Gained supernatant A is the tobacco protein solution containing dissolving in a large number; Then through S4, process and obtain deposit B and supernatant B, according to the heavy characteristic of the molten acid of protein alkali, deposit B is mainly tobacco protein; In supernatant B, be mainly solubility in acid composition, standby; Finally by S5, process, add alkali to regulate pH to 7 ~ 8th, make deproteinized tobacco extract finally for neutral.After the present invention processes, can successfully remove the tobacco protein of 80% left and right in tobacco powder.The preparation method of deproteinized tobacco extract of the present invention can remove the protein in tobacco comparatively up hill and dale, thereby obtain, protein content is low, the good tobacco extract of perfuming effect.
The deproteinized tobacco extract that uses preparation method of the present invention to make adds after pipe tobacco, especially after applying in 0.2 ~ 2% the ratio that applies, fragrance matter and the perfume quantity of the cigarette of making are all greatly improved, and oral cavity throat excitement does not increase, and effectively promotes the quality of cigarette.
