Abstract
The present invention relates to a method for reducing the nitrosamine content in smoke of a cigarette. The method has the scheme that the radiation treatment for the finished cigarette is carried out by using a microwave. The cigarette has the original smell after the microwave treatment, but the total nitrosamine content in smoke of the main flow is reduced to 52 to 76%. Moreover, the total nitrosamine content in smoke of the side flow is reduced to 21.5 to 53%.
Description
The present invention relates to the method for microwave radiation processing finished cigarettes.
Cigarette burning produces main flow and side-stream smoke.Main flume is meant that the smoker sucks the flue gas in oral cavity, and side-stream smoke is meant that cigarette props up spontaneous firing and is directly released into airborne flue gas.
Contained nitrosamine causes people's great vigilance with its strong carcinogenicity in the cigarette smoke.Nitrosamine is the extensive chemical carcinogenic substance, has about 90% to be proved to be and to have carcinogenesis surplus in the of 300 in kind of the nitrosamine compound: internal organs that animal is all and organize all can be by induced tumor, and main target organ is liver, oesophagus, lung, stomach and kidney; Can also carry out heredity by placenta, cause the offspring to distort.The Chinese adult male sex on average consumes 10 cigarette for each person every day, and the average annual aggregate consumption of cigarette has reached 18,000 hundred million, accounts for 1/3rd of global aggregate consumption.The cigarette sidestream smoke directly intersperses among among the crowd, and contaminated environment also injures health, and the involuntary smoker who is hurt reaches several hundred million crowds in China.
Use filter tip, be included in admixture zeolite in the filter tip (referring to patent CH-A-653200, UA-A-3703901, FR-A-2165174, WO 9607335 and WO 9704865) and all be difficult to selectively remove nitrosamine, more can not solve the pollution problem of passive smoking.Japan Patent (JP6214772) adopts menthol, ascorbic acid, lecithin and 4-hydroxyl-3-methoxylbenxaldehyde etc. to make the adsorbent of tar, can reduce the content of flue gas nicotine, CO, benzo [α] pyrene and nitrosamine when being used for the fire end of cigarette.This method is the cost height not only, and because it only has suction-operated, so effect is not remarkable.
European patent (EP0740907) is Y, X, ZSM-5, micro-pore zeolite such as M and β (aperture is 0.5-0.7nm) mixes among the LC-674 with gel (C-Gel), be sprayed on cigarette on the pipe tobacco after forming suspension, the harmful components in combustion process in the catalytic elimination cigarette smoke comprise nitrosamine.Several main components in the nitrosamine such as nitrosonornicotine (NNN), nitroso anabasine (NAB) equal size descend, and the content of dimethylnitrosamine (NDMA) but has rising.Whether the nitrosamine total amount that does not offer some clarification in this patent in cigarette master, the side-stream smoke is significantly reduced.
The applicant in patent application (CN98111479.2), disclose a kind of in pipe tobacco incorporating modified zeolite reduce content of nitrosamines cigarette in the side-stream smoke; The cigarette that reduces the additive of content of nitrosamines in the cigarette smoke and contain this additive is disclosed in patent application (CN99114106.7), all can significantly reduce the nitrosamine total amount in cigarette main flume and the side-stream smoke, and not change original style of cigarette and mouthfeel.
The feature N-NO key of nitrosamine than common C-H, C-C, C-N key a little less than, about 300 ℃, can be disconnected.
American Qiong Ni R William Si handles, reduces the technology of its tobacco-specific nitrosamine (TSNA) content disclosing drying after the microwave radiation is used for tobacco and hemp results among its patent application WO 9805,226 and WO 9858,555 and the CN97198261.The tobacco product of gained is dry and flavous leaf, and it is compared with the tobacco of conventional drying and contains the almost NNN and the NNK of insignificant amount.But this patent need be used the long-time radiation more than 150 seconds, and the drying etc. that is adapted at tobacco leaf is used in handling in earlier stage.
The microwave handling method that the purpose of this invention is to provide content of nitrosamines in a kind of simpler and easy, reduction cigarette smoke that cost is cheaper.
Technical scheme of the present invention is as follows:
Tobacco product after the cigarette (cigarette props up or cigarettes) is evenly paved, and carries out the microwave radiation, and the operating frequency of microwave device is 2450MHz, and radiant power is 500-2000W, and radiated time is 10-100 second.Tobacco product can reduce the content of nitrosamine in this cigarette smoke after radiation.
The microwave handling method of content of nitrosamines in the reduction cigarette smoke that the present invention uses, it can be with packaged cigarettes directly through microwave treatment, and required small investment, technology are simple especially and cost is cheap.Adopt its mouthfeel of cigarette after the present invention handles constant, and the total amount of nitrosamine is lowered 52-76% in the mainstream smoke, then reduces 21.5-53% in the sidestream smoke, thereby can protects smoker and involuntary smoker's health.
Further specify the present invention by the following examples.
Embodiment:, tobacco product is compared through carrying out same test before and after the microwave treatment for detecting the reduction effect of the present invention for nitrosamine total content in the cigarette shreds.The inventor adopts apparatus and method (the Caldwell W. of Caldwell report, J.Assoc.Off.Anal.Chan., 73 (5), 783,1990) collect side-stream smoke, to use pH value instead be 150mL citric acid-disodium hydrogen phosphate buffer solution of 4.5 but it is collected liquid.To the mensuration that cigarette smoke is collected nitrosamine total content in the liquid, the inventor adopts improved AAS (referring to CN97107228.0A).
[example 1] directly places finished cigarettes (fire-cured tobacco type is renovated packing, and tar content is 18mg, and nicotine content in smoke is 1.2mg) on the rotating disk of MLS-1200Mega micro-wave digestion device and carries out the microwave radiation.Refire test in radiation under the 1000W power after 45 seconds, collect main flow and side-stream smoke and analyze the nitrosamine total content.The nitrosamine total content props up from 6.46nmol/ and is reduced to 3.03nmol/ and props up in the side-stream smoke, has been reduced 53.1%.The nitrosamine total content props up from 1.88nmol/ and is reduced to 0.63nmol/ and props up in the main flume, has been reduced 66.5%.The professional of cigarette factory aspirates evaluation to the cigarette before and after the microwave radiation, confirms that its original style is not changed.
