Abstract

The invention relates to a processing method for reducing benzo [ a ] pyrene content in cigarette smoke, which is characterized in that finished cigarettes or box-packed cigarettes are placed in a gamma-ray radiation area for gamma-ray radiation, the adopted gamma-ray radiation source is isotope cobalt-60 or cesium-137 or iridium-192 or selenium-75, the radiation dose is 4KGy-40KGy, and the benzo [ a ] pyrene content in the cigarette smoke can be reduced by 12-70%, and the smoking quality of the cigarettes processed by the method is basically not influenced; in addition, the finished cigarette can be effectively prevented from mildewing in the storage process through gamma ray irradiation.

Description

The processing method of benzo [a] pyrene content in a kind of reduction cigarette smoke
Technical field
The present invention relates to reduce the technology of harmful components in the cigarette smoke, particularly a kind of treatment technology that can effectively reduce benzo in the finished product cigarette smoke [a] pyrene content.
Background technology
Along with improving constantly and progress of science and technology of living standards of the people, smoking is to extremely social concerns of health affected.At present, tobacco science and technology tentatively discloses, harmful components in the coke tar in cigarette, it is one of main matter of harm health of smokers, contain multiple carcinogenic substance and short cancer thing in the tar, for example well-known carcinogen benzo [a] pyrene, its procarcinogen therefore one is exactly: benzo [a] pyrene is at first at 6 hydroxylations, form 6-hydroxy benzo [a] pyrene (it can form covalent compound with nucleic acid), further be oxidized to 6-oxygen benzo [a] pyrene free radical again, this free radical can be attacked human DNA and form bond, thereby causes canceration.In a word, reducing tar content, improve the smoking security and be subjected to the tobacco business common concern always, also is one of urgent problem in the current cigarette industry development.
In recent years, tobacco business is from cigarette process technology aspect both at home and abroad, by improving air permeance for cigarette paper, adopting the filter tip with different structure, the technology such as dilution, expanded cut tobacco stem and reconstituted tobacoo, adding medicinal herb components of punching, reduce tar content in cigarette, some gratifying achievements have been obtained, but the tar content of the cigarette of Chu Shouing is still generally higher in the market.
Along with deepening continuously of " smoking is with healthy " problem, development low tar, low harm cigarette are the only ways of whole world tobacco business.
Summary of the invention
Purpose of the present invention just provides the treatment technology of benzo [a] pyrene content in a kind of technology reduction finished product cigarette smoke simple, with low cost.
The present invention has finished goal of the invention by following technical scheme is provided:
The tobacco product (cigarette props up or cigarettes) that the cigarette machine is produced, after the packing, with hanging the hang-up tobacco bale, be placed in the gamma-ray irradiation district, with radio isotope cobalt-60, caesium-137, iridium-192 or selenium-75 is gamma-ray radiation source, the loading of source amount is 300,000 Curie to 150, ten thousand Curie, and the dosage of irradiation is at 4KGy-40KGy (1KGy=1000Gy).Tobacco product adopts and utilizes the gas chromatography instrument behind gamma-ray irradiation---and select ion monitoring method (SIM) to measure the content of benzo [a] pyrene in the cigarette smoke.Compare sample with the Cigarette that does not pass through gamma-ray irradiation, carry out flue gas analysis and suction evaluation.
The gamma-ray irradiation device that the present invention adopts is made of gamma-rays radioactive source, source storage well, source frame, hoisting mechanism, transfer system, control system, safety interlock system.
The processing method of benzo [a] pyrene content in a kind of reduction cigarette smoke of the present invention can make benzo in the cigarette smoke [a] pyrene content decline 12-70%, and the sucking quality of cigarette is unaffected substantially; In addition, gamma-ray irradiation can also prevent going mouldy in the finished cigarettes storage process effectively.
The gamma-rays that the present invention adopts, its frequency is 3 * 10 12~3 * 10 15MHz, gamma-ray photon energy is up to 1.1732MeV, and therefore, gamma-rays can make generation ionization of most organic matter molecule or chemical bond disconnect.When the gamma-ray irradiation finished cigarettes, cigarette props up the presoma of middle benzo [a] pyrene, accept to become unstable after the gamma-rays photon energy as the electronics in the components such as protein, carbohydrate, cellulose, electronics will transit to the high level track from the low-lying level track, cause atom to be excited state, when excitation energy is higher than molecular ionization potential, the then molecule generation ionization of protein, carbohydrate, cellulose etc.; In addition, molecular excitation can be converted into the chemical bond vibrational energy again, when this vibrational energy surpasses chemical bond energy, be in the covalent bond fracture of molecule of the protein, carbohydrate, cellulose etc. of excitation state, generate little molecule free radical, a nearly step is converted into materials such as amino acid, monose, thereby reaches the purpose that reduces benzo [a] pyrene content in the finished product cigarette smoke.
The ray that gamma-rays sends from atomic nucleus inside when being the decay of radio isotopes such as cobalt-60, caesium-137, iridium-192 or selenium-75.It is widely used in fields such as radioactive breeding, food fresh keeping, disposable use medical article sterilizing, radiographic inspection, radiation chemistry, material composition analysis, customs's container detections, has brought huge benefit to the mankind; In addition, can not produced artificial radioactivity, non-residual toxicity behind the irradiation by the article of gamma-ray irradiation.1997, the International Atomic Energy Agency and the World Health Organization announced that jointly the high dose radiation that surpasses 10KGy (Gy is the abbreviation of Gray, irradiation unit) also is safe, and these conclusions have greatly promoted the development of irradiation industry, are now generally accepted in the world.
