Description
Technical field
The invention belongs to the irradiation technique application; Also belong to tobacco tar-reducing harm reduction technical field; Relate to the application of electron accelerator irradiation technology in reducing tobacco harm, especially a kind of electron accelerator irradiation treatment technology that can reduce volatile phenol content in the cigarette smoke.
Background technology
Tobacco is one of important industrial crops of China, in national economy, occupies an important position.At present, there are 1,100,000,000 smokers in the whole world, and in state-owned more than 300,000,000, smoking has become a kind of social group behavior.As far back as the thirties in 20th century just the someone to propose smoking meeting harm healthy, especially nineteen fifty Britain Royal Society of Medicine and U.S. doctor's political affairs general administration in 1964 formally deliver smoking and healthy relation report, it is harmful clearly to have proposed smoking.Along with people's is to the pay attention to day by day of health, cigarette suck the focus that security has become Recent study, cause showing great attention to of countries in the world government.
The harmful substances that mainly contains that influences the smoking property of cigarette security is tarry matters in smoke, but the material of 99.4% in the tar is harmless, and is aroma component mostly, and harmful components only account for 0.6%, and wherein phenol compound is one type of harmful substance that people pay close attention to.Phenol type substances has strong corrosiveness to skin, mucous membrane, can suppress nervous centralis or infringement liver, renal function, can also promote carcinogenic.Representative in these compounds is phenol, hydroquinones, resorcinol, catechol, paracresol, metacresol and orthoresol, wherein maximum with the harmfulness of phenol again, is classified as one of 7 kinds of cigarette smoke harmful components of evaluating cigarette harmfulness.Phenol compound in the flue gas produces in sucking process, and in smoking process, macromolecular compound mainly is that the polyphenol compound cracking generates phenol type substances in the tobacco leaf.But, the smoker that the whole world is numerous, it is unpractical eliminating tobacco, also is impossible.Therefore, harmful components improve the target that the smoking security has become current international consensus and pursuit to the harm of health in the reduction cigarette smoke, also are one of great research topics that needs to be resolved hurrily in the current tobacco industry development.
At present; Taking a series of reducing tar and reducing harm measures aspect the cigarette process technology in the world; Developed various forms of filter tips, improve cigarette paper natural permeable degree, punching dilution, add technology such as Chinese herbal medicine and chemical addition agent, expanded cut tobacco, stem and reconstituted tobacoo (tobacco science and technology; 2000, (8): 3-6).Comprehensive utilization each item technology can be regulated the tar content of cigarette, but especially not obviously minimizing of phenol type substances of harmful components does not reach the purpose that improves the smoking security.In addition, along with the reduction of tar content, the smoke perfume composition also reduces thereupon, makes the cigarette desalination, also can change cigarette odor-absorbing, causes bad mouthfeel, can not satisfy smoker's requirement.In addition, the method that reduces content of phenol type substances in the flue gas through microwave processing method is arranged also, disclose a kind of cigarette technological method for processing of low phenol content like one Chinese patent application CN 201010288186.7.This invention is to utilize microwave means through changing the content that the cigarette technology for making tobacco threds reduces phenol in the cigarette mainstream flue gas; Though phenol content has certain effect in the flue gas to reducing; But microwave equipment is expensive; Processing cost is high, is difficult for combining with existing tobacco processing technology, is difficult in the suitability for industrialized production and applies.Therefore, these treatment measures do not possess and conform with desirable selectivity, and it is necessary to develop a kind of method of phenol type substances that reduces in the cigarette smoke.
Summary of the invention
A kind of method that can reduce phenol harmful components in the cigarette smoke that the object of the invention provides to above-mentioned existing in prior technology problem just; After its main feature is the electron beam or x-ray irradiation of tobacco leaf/finished cigarette through the electron accelerator generation; Can effectively reduce the phenol harmful components in the flue gas; Improve the security of sucking of cigarette, and can desinsection, sterilization, and do not influence its sucking quality.
