Description

Technical Field

[0001] The invention belongs to the technical field of tobacco flavors and fragrances, and particularly relates to a tobacco flavor bead liquid, a preparation method thereof and an application thereof in cigarettes. Background Art

[0002] Cigarette flavoring technology is the core technology for building Chinese cigarettes. It plays a key role in shaping product style, improving the quality of cigarette aroma and improving the quality of smoking. As the original taste of tobacco, the original aroma of tobacco can give the smoke a rich and soft, rich layer, and outstanding characteristics of tobacco style when smoking. While promoting major special projects such as "harm reduction and tar reduction" and optimizing the formula structure of cigarettes in the tobacco industry, maintaining the taste of cigarettes and giving consumers physiological satisfaction is a huge challenge facing cigarette design. To this end, technicians have developed various types of tobacco flavors and added them to tobacco, mouthpieces or cigarette paper to improve the original aroma of cigarettes, enhance satisfaction and highlight the style characteristics of tobacco leaves.

[0003] Among them, the bursting bead flavoring in the filter rod flavoring has become an important direction for technicians to study tobacco-flavored cigarettes because of its advantages such as controllable flavor substances and large flavor carrying capacity. When the smoker smokes the bursting bead cigarette containing tobacco flavor, he only needs to pinch the bursting bead, and the bursting bead core liquid will be immersed in the silk bundle, and the flavor substances in the further bursting bead core liquid will be released with the smoke, thereby achieving the purpose of enhancing the tobacco flavor of the cigarette. However, the core liquid of the existing tobacco-flavored bursting bead is almost all prepared with full flavor essence. Although the prepared tobacco-flavored bursting bead core liquid can highlight the tobacco flavor to a certain extent, it cannot restore the true tobacco flavor. The main reason is that the chemical composition in tobacco is very complex, and there are more than 700 kinds related to aroma. There are many synergistic effects between these tobacco flavor substances. Therefore, it is very necessary to prepare a tobacco-flavored bursting bead core liquid extracted and separated by pure natural extraction.

[0004] In the method for preparing popping beads, an appropriate amount of diluent, usually caprylic decanoic acid glyceride (ODO), needs to be added to the popping bead core liquid to ensure that the flavor substances have a certain concentration and volatility. It is the best solution to use caprylic decanoic acid glyceride as the extraction solvent of tobacco raw materials to prepare tobacco flavor popping bead core liquid. However, in the prior art, Chinese patent CN201711173594 discloses a method for preparing tobacco flavors using caprylic decanoic acid glyceride and its application in cigarette popping beads. During its preparation process, it needs to be extracted under high temperature heating conditions of 110-150°C, which is prone to decomposition of some heat-sensitive components and loss of volatile aroma components; Chinese patent CN201810585916.6 discloses a method for preparing tobacco flavors with tobacco aroma, tobacco popping beads and popping bead cigarettes, and its preparation process needs to be treated at -20-0°C low temperature and 15-200MPa high pressure, which has high equipment requirements and difficult operation; and it is not easy to directly use caprylic decanoic acid glyceride to extract tobacco flavor substances under easily controlled conditions, because the diffusion and penetration ability of caprylic decanoic acid glyceride is not ideal, and the dissolution state is not good, so it is impossible to quickly and effectively dissolve the flavor substances to fully express the aroma characteristics of the original tobacco aroma. For this reason, it is very necessary to develop a popping bead core liquid with mild preparation conditions and outstanding tobacco aroma characteristics.

[0005] In order to solve the above problems, the present invention is proposed. Summary of the invention

[0006] The present invention aims at the problems that most of the existing tobacco-flavored bursting bead liquids are blended products and cannot restore the original tobacco flavor, and the existing natural tobacco-flavored bursting bead liquids have harsh preparation process conditions and inevitably lose aroma substances during the preparation process. The present invention proposes a tobacco-flavored bursting bead liquid and a preparation method thereof and an application in cigarettes. Liquid membrane separation technology is adopted, and caprylic / capric glyceride is selected as the internal phase. The aroma components in the tobacco raw materials are effectively separated under mild conditions. The prepared tobacco-flavored bursting bead liquid greatly improves the sensory quality of cigarettes.

[0007] The technical solution adopted by the present invention is:

[0008] The first aspect of the present invention provides a method for preparing tobacco-flavored explosive bead liquid, comprising the following steps:

[0009] Step (1), mixing tobacco raw material and tobacco aroma component extraction solvent in proportion, performing hot extraction 2-3 times, cooling, filtering, and combining the filtrate to obtain tobacco extract;

[0010] Step (2), mixing the surfactant, the membrane carrier and the aqueous phase in proportion, adding an equal volume of the internal phase caprylic decanoic acid glyceride to the mixed solution, placing the resulting mixed system in an emulsification container and stirring and emulsifying at a high speed to obtain a stable oil-in-water-in-oil (O / W / O) emulsion;

[0011] Step (3), mixing the tobacco extract obtained in step (1) and the emulsion obtained in step (2) in proportion, stirring, letting the mixture stand, separating the emulsion phase and the organic phase, and collecting the emulsion phase to obtain a mixed solution containing tobacco aroma components;

[0012] Step (4), centrifuging the emulsion obtained in step (3) to separate the oil phase and the emulsion, collecting the oil phase, removing excess water with anhydrous Na2SO4, filtering, and collecting the filtrate to obtain a caprylic decanoic acid glyceride solution containing aroma components;

[0013] Step (5), the caprylic decanoic acid glyceride solution containing the aroma component obtained in step (4) is concentrated under reduced pressure until no liquid drips out, the tobacco aroma component extraction solvent is removed, and the solution is cooled to room temperature to obtain the tobacco aroma bursting bead liquid.

[0014] Preferably, in step (1), the tobacco aroma component extraction solvent is one or both of ethyl acetate and n-hexane;

[0015] The tobacco raw material is one or more of Honghua Dajinyuan flue-cured tobacco leaves, K326 flue-cured tobacco leaves, Zimbabwe tobacco leaves, Yunnan dry tobacco leaves, and Baile tobacco leaves;

[0016] The mixing ratio of the tobacco raw material and the tobacco aroma component extraction solvent is 1:8-15 by mass ratio;

[0017] The heat extraction temperature is 50-90° C., and the heat extraction time is 1-5 h.

[0018] Preferably, in step (2), the mixing volume ratio of the surfactant, the membrane carrier, the aqueous phase and the internal phase caprylic decanoic acid glyceride is 1-10:1-10:80-98:80-98;

[0019] The high-speed stirring emulsification speed is 5000-10000r / min, and the stirring time is 10-20min;

[0020] In the step (3), the mixing ratio of the tobacco extract and the emulsion is 1-5:5-10; the stirring speed is 100-500 r / min, the stirring time is 30-60 min, and the standing time is 2-4 h;

[0021] In the step (4), the centrifugal speed is 3000-5000 r / min, and the centrifugal time is 30-90 min;

[0022] The dosage of anhydrous Na2SO4 is 5-10% of the oil phase mass.

[0023] Preferably, the surfactant in step (2) is Tween 20, the membrane carrier is cuprous ammonium acetate, and the aqueous phase is deionized water.

[0024] Preferably, the temperature of the reduced pressure concentration in step (5) is 40-60° C., and the vacuum degree is -0.07 to -0.09 MPa.

[0025] Step (2) and step (3) mainly use liquid membrane separation technology. Liquid membrane separation technology is a process technology that uses a liquid membrane as a separation medium to separate two mutually soluble liquids with different compositions, and uses the concentration difference as a driving force to achieve the separation of a certain type of substance. It can also promote mass transfer by adding a carrier to the liquid membrane and utilizing the reversible coordination reaction between the component and the carrier.

[0026] Whether the liquid membrane separation technology can achieve effective separation of the target substance depends mainly on the construction of the liquid membrane and the process of implementing the separation. The liquid membrane is composed of a membrane phase, an internal phase and an external phase, and the membrane phase is composed of a membrane solvent, a surfactant, a membrane carrier, etc. The membrane solvent is the matrix material of the membrane phase, which is equivalent to the hydrophobic part of the lipid bilayer of the biological membrane, accounting for about 80%-90% of the total membrane phase; the surfactant is used to activate the surface of the membrane solvent, and then dispersed in another immiscible liquid phase to form an emulsified liquid membrane; the membrane carrier plays a decisive role in the separation speed and is the key to the liquid membrane separation technology. Because the membrane solvent has the ability to dissolve, some substances can diffuse through the membrane solvent, that is, the purpose of mass transfer and separation of substances is achieved.

[0027] According to the present invention, the tobacco extract obtained in step (1) is the external phase, the liquid membrane is prepared in step (2), and the liquid membrane separation process is performed in step (3).

[0028] The second aspect of the present invention provides a tobacco-flavored explosive bead liquid prepared by the preparation method described in the first aspect.

[0029] The third aspect of the present invention provides a popping bead comprising the tobacco-flavored popping bead core liquid prepared by the preparation method described in the first aspect.

[0030] The fourth aspect of the present invention provides an application of tobacco-flavored bursting bead liquid prepared by the preparation method described in the first aspect in cigarettes, wherein the tobacco-flavored bursting bead liquid uses caprylic acid glyceryl ester as the bursting bead liquid solvent and has good adaptability to machines, and the tobacco-flavored bursting bead liquid can greatly enhance the tobacco aroma, significantly enhance the smoke concentration and strength, and has a comfortable aftertaste, significantly reduces impurities, and significantly improves irritation.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The present invention applies liquid membrane separation technology to the separation of tobacco flavor substances for the first time. After a large number of experiments, the inventors specifically selected cuprous ammonium acetate as the membrane carrier and selected caprylic decanoic acid glyceride as the internal phase. The tobacco flavor bead liquid finally separated significantly improves the quality of cigarettes.

[0033] 2. The present invention innovatively adopts a two-step method to extract and separate the original aroma substances of tobacco. Specifically, a specific proportion of ethyl acetate and / or n-hexane is first used as an extraction solvent to extract as many main aroma components in the tobacco raw materials as possible, and then liquid membrane separation technology is used to separate and enrich the aroma substances that can enhance the original aroma of tobacco.

[0034] 3. After extensive research, the present invention uses caprylic decanoic acid glyceryl as the internal phase, adds a specific proportion of cuprous ammonium acetate as a membrane carrier, and Tween 20 as a surfactant, which ultimately improves the diffusion and penetration ability of caprylic decanoic acid glyceryl, improves the dissolution state of caprylic decanoic acid glyceryl, and effectively dissolves the flavor substances.

[0035] 4. The tobacco original fragrance bursting bead core liquid prepared by the present invention has a stable online bursting bead forming effect, and after being pinched, the personalized fragrance characteristics are obvious, and the tobacco original fragrance flavor is better retained, and the fragrance is natural, pure, coordinated, and natural. After being pinched, the personalized fragrance characteristics are obvious, the fragrance is rich and full, pure and comfortable, and the aftertaste is clean and comfortable, which more completely expresses the tobacco aroma characteristics; the aroma intensity is enhanced, the top fragrance is rich and full, the tobacco aroma is supplemented, the smoke is fine and soft, the smoke is rich and full, the layering and satisfaction of the smoke fragrance are enhanced, and the quality of cigarettes is improved.

[0036] 5. The present invention is simple to operate, has mild conditions, is easy to control, is suitable for actual production conversion, and is suitable for promotion and application as a method for preparing special tobacco flavors. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] Comparative Example 1

[0063] Compared with Example 1, this comparative example is different in that caprylic decanoic acid glyceride is used to directly extract and separate the flavor substances of the tobacco raw material in this comparative example, and the specific steps are as follows:

[0064] Take Honghua Dajinyuan tobacco raw materials that have been aged for more than 2 years and have a moisture content of ≤5.0%, crush and sieve, take Honghua Dajinyuan tobacco raw materials of 40 mesh and below and mix them evenly with caprylic decanoic acid glyceride in a mass ratio of 1:8, stir at room temperature at a stirring speed of 30r / min for 1h, then heat the system to 65°C, and heat the system at this temperature for 2h, during which time the stirring is continuously carried out at a stirring speed of 30r / min. After the extraction is completed, the system is cooled to room temperature, filtered through 400-mesh gauze, the filtrate is collected, and the above steps are repeated for secondary extraction, wherein the second hot extraction time is 1, and then the two filtrates are combined to obtain the bursting bead core liquid directly extracted with caprylic decanoic acid glyceride.

[0065] Application Comparative Example 1

[0066] Referring to the conventional process of popping bead cigarette production, the tobacco flavor extracts prepared in Examples 1-3 and Comparative Example 1 were respectively made into 4 kinds of popping bead cigarettes, and cigarette-Example 1 (50 cigarettes), cigarette-Example 2 (50 cigarettes), cigarette-Example 3 (50 cigarettes), and cigarette-Comparative Example 1 (50 cigarettes) were obtained. All the above cigarettes were placed in a constant temperature and humidity chamber (temperature 22±1°C, humidity 60±2%) for 48 hours of equilibrium, and were evaluated by smoking experts in accordance with "GB5606.4-2005 Cigarette Part 4 Sensory Technical Requirements" and "YC / T 497-2014 Cigarette Chinese Cigarette Style Sensory Evaluation Method". The results of the smoking evaluation are shown in Tables 1, 2, and 3:

[0067] Table 1 Results of smoking evaluation of tobacco flavor popping beads cigarettes

[0068]

[0069] Table 2 Evaluation results of the comfort characteristics of tobacco flavor popping beads cigarettes

[0070]

[0071] Table 3 Evaluation results of smoke characteristics of tobacco flavor popping beads cigarettes

[0072]

[0073] from Figures 1 to 3It can be seen that the preparation method of the present invention effectively enriches the main aroma components from the tobacco extract, and compared with the method of comparative example 1, the aroma components of the popping bead core liquid obtained by the preparation method of the present invention are rich. Combined with Tables 1 to 3, it can be seen that the tobacco original aroma popping bead core liquid prepared by the present invention is prepared into popping beads and applied to cigarettes. It has a prominent tobacco aroma when smoking, significantly improves the smoke concentration and strength, and has a comfortable aftertaste, significantly reduces impurities, and greatly improves irritation. However, the popping bead core liquid prepared by the method of comparative example 1 does not have the above-mentioned obvious effects. This is because comparative example 1 uses caprylic decanoic acid glyceride for direct heating extraction. Due to the unsatisfactory penetration and diffusion capacity of caprylic decanoic acid glyceride, no more flavor substances are extracted.

[0074] At the same time, it is explained that the tobacco bead core liquid prepared by the method through the combination of solvent extraction and emulsion liquid membrane separation technology can more completely express the original aroma characteristics of tobacco, with a strong top aroma, enhanced aroma intensity, and significant flavor enhancement effect, and has good application prospects.
