Abstract
The present invention adopts trace elements of selenium and zinc beneficial to human bodies to reduce the contents of tar and polycyclic aromatic hydrocarbon generated in the process of tobacco combustion, and the effect is obvious. Simultaneously, the present invention enhances the level of selenium and zinc in vivo of smokers and the capability of the epidemic prevention of human bodies on some diseases. The compound tobacco additive contains 1 to 4% of zinc acetate dihydrate and 0.0001 to 0.0003% of sodium selenite in tobacco shreds, and has the characteristics of convenient preparation, low cost, convenient popularization, etc. Furthermore, the compound tobacco additive is suitable for the production industry of cigarettes in China, and the original color and the original fragrance are fundamentally unchanged.
Description
The present invention adds compound additive reduces the tar that tobacco produces effectively in combustion process a kind of method in pipe tobacco, this kind additive is to utilize human body beneficial's trace element zinc, selenium are made.
The past people only think that contained nicotine is the main component that diminishes health in the tobacco.Modern science then thinks, what in the tobacco health is had more harm is not nicotine, but the tar ingredients in the flue gas.Contain a large amount of tar in the cigarette smoke, a regular-size cigarette tar content can reach about 30 milligrams.Think through the pharmacology evaluation: contain carcinogen in the tarry matters in smoke, therefore proof: tarry matters in smoke are the serious threats to health.Because the carcinogen in the discovery tobacco in the tar ingredients of flue gas, thereby harm of smoking is generally accepted by public institute.The many countries in west forbid that with the government decree form tobacconist advertises.Anti-in addition cigarette group occurs in succession, conducts vigorous propaganda harm of smoking.Face huge pressure from public opinion, the tobacconist just steps up to develop low-coke tar cigarette in order to extricate oneself from a predicament.Low-coke tar cigarette is born under this situation.
British government was announced the various cigarette tar contents of home sale in 1973, selected for the smoker.British government is divided into several levels with the height of tar content again in the near future.Its standard is as follows:
The division of above-mentioned tar is admitted for various countries in fact now and is accepted, and the U.S. just indicates national tobaccoman various trade mark cigarette tar contents to be reduced to below 15 milligrams to nineteen eighty-three at that time.The Chinese government also made stipulations in 1986: must indicate the class of tar content from the cigarette case of the various trades mark in 1987, and the regulation tar content divides high, normal, basic three shelves:
China is the first production and marketing big country now in the world, and cigarette quality particularly also lags behind international most advanced level in the work of reduction tobacco tar Study on content.Only there is a small amount of low tar cigarette listing in China at present, can not satisfy numerous smokers' demand far away.Therefore reduce no matter tar content is from raising people ' s health level in the flue gas, the cigarette product of China is squeezed into the international market more, obtaining bigger several respects such as economic benefit all is imperative key subjects.
Since the sixties, external tar content for the reduction smoke of tobacco has carried out number of research projects.Except the improvement tobacco bred, adopt the method for physics more, these methods comprise: improve the tobacco leaf processing method, improve the air permeability of cigarette paper, improve the filtration of filter tip and render a service or the like.These class methods are effectively reducing on the harmful components of flue gas, but flue gas also desalinated simultaneously, and the bigger people of craving for tobacco is not being met.Therefore, they tend to dark suction, heavily inhale and inhale morely, thereby make the total amount of the harmful components that these people suck and may not be certain to have tangible minimizing.
Improve the growing and cultivation technology of tobacco, improve quality of tobacco, this yes a kind of good method of improving quality of tobacco.But the time that obvious this way needs is long, and it is slow to take effect, and cost also can correspondingly increase.
Reducing the content of tar with the way of chemistry, at present, mainly is to add some combustion adjuvant, diluent, catalyst etc. in cigarette.Reduce the content of tar by the efficiency of combustion that improves cigarette, and can reduce some harmful components in the flue gas selectively, as people such as U.S. Norman V, with zinc oxide as additive in cigarette, polycyclic aromatic hydrocarbon content in the catalytic decomposition flue gas, it lowers efficiency and can reach 50%.(seeing CA Vol77149831111972).Use this way, additive is to do to mix to mix pipe tobacco, does not meet the present tobacco curing technology of China.And the method for indication of the present invention, its zinc acetate and sodium selenite compound additive can be water-soluble fully, can be sprayed on the pipe tobacco equably.
The objective of the invention is to use the additive in cigarette that human body beneficial's trace element is made, can reduce the content of tar, might play the prophylactic treatment effect to some disease again, (ArchEnvironHealth39(6) 419-4241984 among this way is being studied abroad) but do not see that formal achievement in research is arranged.
The present invention uses human body beneficial's trace element is handled tobacco, has promoted the completing combustion of pipe tobacco, has reduced the tar content in the flue gas.Its mechanism is speculated as: as the very easy decomposes of the zinc acetate of additive, under the situation of pipe tobacco burning, change zinc oxide into, reaction equation is:
In above-mentioned reaction, acetate is oxidized to carbon dioxide and water, emits a large amount of heat energy, the combustion heat △ H of acetic gas
298=-104.3 kcal/mol.Play combustion-supporting effect thereby improved ignition temperature, the zinc oxide of generation plays the catalytic decomposition polycyclic aromatic hydrocarbon.
In addition, the polycyclic aromatic hydrocarbon in the tar is considered to carcinogenic chief culprit.The sodium selenate that adds can be absorbed by the body.EPDML research and zoopery have proved that body improves the generation that the selenium level can effectively prevent diseases such as lung cancer.Having shown also in our biochemical test that sodium selenite has the reduction effect to the toxicity of tar, might be that selenium can be removed harmful free radical that polycyclic aromatic hydrocarbon produces.
Adopt the pipe tobacco that the present invention handled, the tar content in the cigarette smoke can be reduced by 16%～20%.The content of polycyclic aromatic hydrocarbon reduces by 30%～50%, and free-radical contents reduces by 20%.The result of study of relevant polycyclic aromatic hydrocarbon is tested with U.S. Hewlett Packard5880A type capillary chromatography; Tar is tested because of Filtrona-302 type smoking machine with English; The tar free radical is that the JES-FEIX type electron spin resonanceapparatus that Japan produces is tested.(seeing the data of consulting for details)
The preparation and the embodiment of the micro-compound additive that this method adopted are described below: zinc acetate is dissolved in the sodium selenite that adds certain ratio in the water more fully with its maximum solubility, then solution is diluted to certain volume.Compound additive is sprayed on the tobacco leaf before the perfuming equably, and the sprinkling amount is that per 100 gram pipe tobaccos add zinc acetate 1～4 gram; Sodium selenite 0.0001 gram～0.0003 gram.
The concrete prescription of compound additive has following a few example:
Example one, zinc acetate and sodium selenite add percentage by weight in the pipe tobacco be 3% and the weight of the weight/pipe tobacco of 0.0002%(zinc acetate or sodium selenite).Before tobacco perfuming, be sprayed on the pipe tobacco.
Result: reduce tar 16.22%, polycyclic aromatic hydrocarbon 28.5%, free radical 19.2%
Example two, the percentage by weight that zinc acetate and sodium selenite add in the pipe tobacco is 4% and 0.0001%.(weight of the weight/pipe tobacco of zinc acetate and sodium selenite) before tobacco perfuming, is sprayed on the pipe tobacco.
Result: reduce tar 18.32%, polycyclic aromatic hydrocarbon 39.2%, free radical 18.82%
In sum, be very significant with tobacco additive agent of the present invention to tar content, polycyclic aromatic hydrocarbon and the free-radical contents effect that reduces in the smoke of tobacco.And can improve the level of smoker to healthy trace elements with household in involuntary smoker's body, strengthen body immunity.
From the color, smell and taste aspect of cigarette, the cigarette that the tobacco of handling with the present invention is made, through the smoker and relevantly comment the cigarette expert appraisal: color, smell and taste do not have harmful effect, and the assorted gas and the excitant of cigarette alleviate to some extent.
From the possibility of promoting, the adding of trace element zinc, selenium does not change existing cigarette process.And 1 fen of cost less than of every bag cigarette increase.All kinds of cigarettes all can add, and the scope of application is wide.
Therefore it seems, the present invention because it to content of harmful in the tar reduce effect remarkable, easy to make, with low cost, be convenient to healthy and helpful to human body of the trace element promoting, added, will inevitably to tobacco change from now on cigarette product structure, produce low-toxic cigarette and produce positive role and obtain good effect.Its economic benefit also is very considerable.
