Description
Technical Field
The invention relates to the field of tobacco, in particular to a Chinese herbal medicine-supermolecule aerogel and a preparation method and application thereof.
Background
Tobacco has been a consumer product of life for refreshing, calming and soothing the spirit and has been in the history of human development. However, during smoking, the temperature of the tobacco is raised from normal temperature to 950 ℃, and in the process, the oxygen content, the combustion degree and the components of the cigarette are complex and various, and the combustion of the cigarette actually generates a series of chemical reactions in a carbonization, pyrolysis, condensation and other modes to generate smoke with extremely complex components. Researches show that 92% of cigarette smoke is gas such as carbon monoxide, hydrocyanic acid, ammonia and the like; 8% of the smoke dust with the particle size of 0.1-2 μm is particulate matters, the particulate matters are called tar, and nicotine, polycyclic aromatic hydroxyl, benzopyrene, beta-naphthylamine and the like are contained in the particulate matters, so that the particulate matters are main harmful matters of cigarettes.
At present, the technologies of tobacco tar reduction mainly include two types: firstly, the production amount of tar is reduced: for example, the tar content in the tobacco raw materials is reduced by agricultural measures, or the tar content in the cigarette products is reduced by technical measures such as adding tobacco sheets, adding combustion improver, expanding tobacco shreds, changing the specifications of cigarettes, reducing the tobacco shred quantity, reducing the suction port number of cigarettes and the like. Secondly, the flue gas filtration efficiency is improved: by changing the filter aids and parameters, adding adsorbents, etc.
However, these methods have little room for tar reduction at present, and low tar cigarette formulations have high tobacco quality requirements. In addition, compared with the gaps between acetate filaments in the cigarette filter tip (30-100 μm), the particle size of the tar is integrally and integrally smaller by an order of magnitude, so that the acetate filter tip has a relatively open structure to the cigarette smoke, and if the pores of the filter tip are blindly reduced, the combustion effect of the cigarette is affected.
Disclosure of Invention
Aiming at the problems existing in the prior art, the invention provides the Chinese herbal medicine-supermolecule aerogel and the preparation method and application thereof, which can achieve the effect of reducing tar while increasing the health degree and the taste of cigarettes.
In a first aspect, the present invention provides a method for preparing a herbal-supramolecular aerogel comprising: mixing supermolecule aerogel with solution of lipophilic Chinese herbal medicine component, soaking after ultrasound, and drying; the supramolecular aerogel is prepared from raw materials including sodium alginate and carboxymethyl cyclodextrin.
The hydrogel is a three-dimensional polymer network with extremely high hydrophilicity formed by crosslinking macromolecular polymer chains, has a large number of uniform pore diameters, and can obtain aerogel by losing moisture through freeze drying of the hydrogel, and the three-dimensional pore structure can be completely reserved in the process. The supermolecular aerogel disclosed by the invention refers to an aerogel containing supermolecules. Supermolecules are generally defined as complex, organized aggregates of two or more molecules held together by intermolecular interactions, and maintained in a degree of integrity that provides defined microscopic and macroscopic properties. Reported supermolecular macrocyclic hosts include DNA, crown ethers, cyclodextrins, calixarenes, calixapyrroles, calixazoles, cucurbiturils, pillar arenes, and the like.
Sodium alginate is a byproduct of brown algae kelp or gulfweed after extracting iodine and mannitol, and the molecule is formed by connecting beta-D-mannuronic acid (beta-D-mannuronic acid, M) and alpha-L-guluronic acid (alpha-L-guluronic acid, G) according to a (1- & gt 4) bond, is a natural polysaccharide, and has the stability, solubility, viscosity and safety required by auxiliary materials of a pharmaceutical preparation. Sodium alginate has been widely used in the food industry and in the pharmaceutical field.
Since the outer rim of cyclodextrin is hydrophilic and the inner cavity is hydrophobic, it can provide a hydrophobic binding site like an enzyme, as a Host (Host) enveloping various suitable guests (guests), such as organic molecules, inorganic ions, and gas molecules, etc.
Based on the cavity property of cyclodextrin, the Chinese herbal medicine components are combined into the cavity of the cyclodextrin through the actions of host and guest by ultrasonic and soaking, and the reticular porous Chinese herbal medicine-supermolecule aerogel is obtained after drying. Tobacco tar is an extremely complex mixture of numerous hydrocarbons and oxides, sulfides and nitrides of hydrocarbons, and the polarity of the aerogel network can be altered by modifying the oleophilic herbal ingredients such as menthol into the aerogel. The lipophilic aerogel is then implanted into a cigarette filter to increase the filter's effectiveness in filtering oily substances (e.g., tar, benzene derivatives) from the smoke to some extent. In addition, the Chinese herbal medicine components can positively influence the taste diversity of cigarettes through volatilization, and achieve the purpose of wetting the throat and clearing the throat of smokers.
According to the preparation method of the Chinese herbal medicine-supermolecule aerogel provided by the invention, the mass ratio of the sodium alginate to the carboxymethyl cyclodextrin is 3-5:1.
In some embodiments of the present invention, the preparation process of the herbal medicine-supramolecular aerogel comprises:
s1, weighing 5g of sodium alginate, dissolving in 100ml of distilled water to obtain 5% (W/V%) sodium alginate solution, and then weighing 1g of carboxymethyl cyclodextrin, dissolving in 5% sodium alginate solution.
S2, weighing 0.2g of calcium carbonate, adding the calcium carbonate into 20mL of the sodium alginate cyclodextrin solution, stirring vigorously to uniformly distribute the calcium carbonate in the sodium alginate cyclodextrin solution, adding 0.2g of gluconolactone, continuing stirring vigorously for 1min, and standing for gelling.
S3, freezing the prepared hydrogel for 24 hours at the temperature of minus 20 ℃, and then drying the hydrogel in a freeze dryer for 48 hours to obtain the supermolecule aerogel.
S4, putting the dried supermolecule aerogel into 99% menthol solution, carrying out ultrasonic treatment for 3 hours, then soaking for 24 hours, taking out, putting into an oven, and drying at 60 ℃ for 24 hours to remove menthol which is not complexed with cyclodextrin.
According to the preparation method of the Chinese herbal medicine-supermolecule aerogel provided by the invention, the lipophilic Chinese herbal medicine component is one or more of menthol, eucalyptus, origanum, clove, achyranthes bidentata, thyme, lemon and rose essential oil.
Further, when the lipophilic herbal ingredient is a solid, for example menthol crystals, a solution having a concentration of more than 95% is formulated using a solvent in which it is soluble;
when the lipophilic herbal ingredient is a liquid, such as menthol essential oil, it is directly mixed with the supramolecular aerogel.
Menthol is a kind of Chinese medicine extract, is a kind of terpenoid organic compound, has special fragrance of peppermint, and is cool after initial burning. Can be used as irritant in medicine, acts on skin or mucosa, and has effects of refreshing and relieving itching; it can be used as wind-dispelling medicine for treating headache, and inflammation of nose, pharynx and larynx. According to the invention, after menthol is modified into the supermolecule aerogel, substances such as tar in smoke can be better adsorbed, the taste of cigarettes can be increased, and menthol has the effects of clearing heat from throat and benefiting throat, so that the menthol plays a positive role in the health of smokers.
According to the preparation method of the Chinese herbal medicine-supermolecule aerogel provided by the invention, the ultrasonic power is 200-300W, and the time is 2-3h.
According to the preparation method of the Chinese herbal medicine-supermolecule aerogel provided by the invention, the soaking time is 24-48h.
According to the preparation method of the Chinese herbal medicine-supermolecule aerogel, the drying is freeze drying, and the treatment temperature of a sample before freeze drying is-80 to-20 ℃.
In a second aspect, the present invention provides a herbal-supramolecular aerogel prepared by the above-described preparation method.
In a third aspect, the present invention provides a method for reducing tobacco tar comprising disposing the above herbal-supramolecular aerogel in a cigarette filter.
In a preferred embodiment of the present invention, the Chinese herbal medicine supermolecule aerogel is made into a cylinder with the same diameter as the cigarette filter tip, and is arranged in the middle section of the cigarette filter tip, and the length of the cylinder is 1/5-1/3 of the cigarette filter tip.
Because the mesh porous structure of the prepared Chinese herbal medicine-supermolecule aerogel has more pore diameters and complex internal channels, the cigarette filter tip can not be directly used as the cigarette filter tip because the cigarette filter tip can not meet the smoking requirement of the cigarette, and the tar filter system of the cigarette is formed by combining the cigarette filter tip with the traditional cigarette filter tip. Compared with the traditional acetate fiber cigarette filter tip, the cigarette filter tip of the composite aerogel can intercept and adsorb tar in cigarettes through more proper pore diameter and added lipophilic Chinese herbal medicine components, and can adsorb some harmful free radicals in smoke through a principle of host-guest combination. Experimental data show that compared with the traditional single acetate fiber filter tip, the composite cigarette filter tip has better tar reducing effect, and the taste of the cigarette can be improved by selecting proper Chinese herbal medicine components.
The method of the invention is mainly aimed at the improvement scheme of reducing tar in the cigarette filter tip process. From the economical point of view, the materials used in the method are cheap and easy to obtain and are common raw materials in food and medicine processing; from the perspective of safety and health, the materials are widely used in the fields of medicines, foods and the like, and have no harm to human bodies; from the usability, the scheme not only can reduce tar and other harmful gas molecules in the smoke of the cigarette, but also can add some flavor and taste to the cigarette, thus being a new mode with various tastes. Therefore, the method has good application prospect, not only better ensures the health of vast smokers, but also provides more special fragrance for cigarettes.
The invention provides a Chinese herbal medicine-supermolecule aerogel, a preparation method and application thereof, wherein based on the cavity property of cyclodextrin, chinese herbal medicine components are combined into the cavity of the cyclodextrin through the actions of host and guest by ultrasonic and soaking, and the reticular porous Chinese herbal medicine-supermolecule aerogel is obtained after drying. The aperture of the dry aerogel is closer to the grain diameter of the large-size tar, and the large-size tar can be better filtered, so that the tar content in the flue gas is reduced. Meanwhile, the Chinese herbal medicine components in the aerogel are also beneficial to adsorbing or neutralizing harmful substances such as tar and the like, so that the filtering effect on the tar is improved. In addition, these herbal ingredients can also positively affect the variety of tastes of cigarettes.
