Abstract
The present invention relates to a gas-phase free radical scavenger for a cigarette, particularly to a cigarette with low free radical and low toxicity and a production method thereof. The gas-phase free radical scavenger is prepared from tea polyphenol and vitamine C in preferable proportion of 1: 1.
Description
The present invention relates to a kind of cigarette gaseous phase free radical scavenger, low free radical and low toxicity cigarette and production method thereof.Or rather, the present invention relates to a kind of low free radical and low toxicity cigarette and production method of making as the cigarette free radical scavenger with Tea Polyphenols, vitamin C and bluish dogbane thereof.
Smoking to the harm of health by many investigation and experiment confirm.
When world national governments advocate smoking cessation and legislation ban on opium-smoking and the opium trade, scientist and tobacco scientific workers are actively making great efforts the harm of research reduction cigarette, development is low poisons and the nonhazardous cigarette, it is little to be intended to solve comprehensive ban on opium-smoking and the opium trade effect, the contradiction that aspects such as the consumer is numerous, the economic benefit of smoking and social benefit, smoking and health exist.
In the production of cigarettes field,, generally be to adopt the cigarette filter technology for eliminating the noxious material in the cigarette.The cigarette filter great majority are made by NACF or acetate fiber filter material, and this respect can be referring to CN2174854Y and CN/088763A.Another kind of means are at pipe tobacco itself, promptly pipe tobacco are carried out specially treated, referring to CN1045515A.CN2132392Y discloses a kind of activated carbon fiber composite cigarette filter tip capable, and its filter fiber is formed by the fiber composite butt joint of two sections unlike materials at least.
But, the above-mentioned commonsense method that removes the noxious material in the cigarette does not all have from dealing with problems in essence.In fact, along with free radical medical science and the biological development of free radical, epidemiology survey confirms: free radical is the most serious product of harm in the cigarette.It can directly or indirectly be attacked, damaging cells, and can cause the generation of various diseases.Free radical is a carcinogenic substance, can cause cancer.This is noted by the country of some science prosperity.
In recent years, aspect the research of cigarette free radical, be confined to inquire in theory in the world, radicals scavenging is technical in cigarette does not become effective, and up to now, does not see the report of low free radical and low toxicity cigarette as yet.
The research that reduces free-radical contents in the cigarette is very a forward position and a complicated problem, does not solve in the world so far at all.Some research institutions only concentrate on the tar in the research of cigarette free radical, and tar content reaches the purpose that reduces free radical in the cigarette to reduce.
Therefore, be starved of:
1. set up the accurate detection of a cover and confirm in the cigarette and the free radical kind and the method for character, particularly gaseous phase free radical that produce in the smoking process;
2. study its mechanism, and work out efficiently harmful targetedly free radical scavenger of nontoxic attached effect on this basis human body harm;
3. darker because of hazard ratio solid phase (tar phase) the free radical extent of injury of gaseous phase free radical, it is more difficult to remove, therefore, research object and sweep-out method must be based on gaseous phase free radicals, and should set up the free radical scavenger adding method that adapts to modern cigarette process technical conditions.But fact proved, be very difficult.
Task of the present invention is to solve above-mentioned prior art problems, and a kind of low free radical and low toxicity cigarette and production method thereof are provided.
Free radical comprises solid phase free radical and gaseous phase free radical two parts in the cigarette, by the research of cryotronics spin resonance (ESR) method, find that the solid phase free radical mainly is polycyclic aromatic hydrocarbon free radical and quinone/semiquinone (Q/QH) free radical, wherein the Q/QH free radical accounts for 85% greatly, and this type free base is easy to be oxidized to oxygen radical.Mostly free radical in the gas phase is instantaneous unstable the existence, can not directly observe with the ESR spectrometer, and the inventor has set up with spin catching agent PBN or DMPO and unsettled radical-scavenging lived and changed into a kind of spin adduct that can use the ESR wave spectrum to detect.That is: adopt spin capture (DMPO or PBN) and ESR technology to combine and distinguish gaseous phase free radical.Assert that through test it is alkoxy radical and alkyl diradical.
Discover that gaseous phase free radical and solid phase free radical all are the free radicals that human body is had serious harm in the cigarette, but gaseous phase free radical has stronger oxidisability, and the solid phase free radical has certain reproducibility.Cigarette smoke is the Main Ingredients and Appearance in consumer's suction body, is the main path of harmful free radical harmful to human.
At These characteristics, on the strategy of cigarette radicals scavenging, be target with comprehensive removing cigarette free radical, serve as basic to remove gas phase.
Scavenger requires efficiently, has no side effect, and is pointed to free radical in the cigarette, technical feasible at cigarette producing process, and has better economic.
Through experimental study, the inventor finds, selects cigarette radicals scavenging agent prescription: Tea Polyphenols, vitamin C and bluish dogbane can suppress the cigarette toxin effectively as main component, particularly reduce gaseous phase free radical in the cigarette.
For this reason, determine the technology path of following removing free radical: add bluish dogbane medicinal extract and remove the solid phase free radical in pipe tobacco, add free radical scavenger and remove its gaseous phase free radical in filter tip, the two coordinates to remove free radical in the cigarette comprehensively.Experiment showed, that above-mentioned three kinds of components have removes the effect concertedness preferably.Use single component to remove effect and be lower than composite components removing effect.Just be based on above discovery, just finishing the present invention.
The present invention relates to a kind of low free radical and low toxicity cigarette, it is characterized in that the filter tip of cigarette is mixed and made into finite concentration and active carbon with Tea Polyphenols and vitamin C.According to the another embodiment of the present invention scheme, when cigarette throwing, soak into pipe tobacco, to obtain to fall the optimum synergistic effect of low smoke and non-toxic with bluish dogbane medicinal extract.
Remove in the prescription at gaseous phase free radical, Tea Polyphenols and ascorbic percentage by weight are 1: 1.The purity of Tea Polyphenols is preferably 60-95%, is higher than the upper limit 95%, and it is uneconomical to purify; And being lower than lower limit 60%, practical function is insufficient.Accounting for pipe tobacco gross weight 1-5 ‰ according to the content that experiment showed, scavenger is advisable.
Term " Tea Polyphenols " is a kind of green-tea extract, is actually the blocking agent of lipid peroxidation free chain reaction.
Should be pointed out that Tea Polyphenols, bluish dogbane and ascorbic combination as free radical scavenger basis of the present invention are necessary.If only select wherein a kind of for use, though the effect of falling low smoke and non-toxic is also arranged, effect is insufficient.That is to say the arithmetic sum height of the combination of these three kinds of compositions of employing than the efficient of using these three kinds of compositions to obtain respectively separately.Facts have proved that use radicals scavenging technology of the present invention, the gas phase clearance rate can reach 26.8%.
The method of soaking into pipe tobacco with bluish dogbane medicinal extract illustrates that it is for referencial use that this patent related content is incorporated into this paper at this in all United States Patent (USP)s 06/711,620 of the inventor.
The radicals scavenging effect is measured by the following method:
Radicals scavenging solution is sprayed onto on the pipe tobacco equably dries cigarette.Make reference system with the cigarette of the same race that does not add bluish dogbane, make trapping agent with PBN or DMPO and collect gaseous phase free radical, detect with the ESR method, pretending with the ESR wave spectrum of the cigarette that added scavenger and reference system cigarette free radical respectively is the relative value of free-radical contents, under the same conditions, the linearity of the wave spectrum of these two kinds of cigarette is identical with live width.Free radical scavenging activity calculates as follows:
E=(HO-HX)/HO * 100% wherein HO is that the reference system peak is strong, and HX is that to add the peak of sample of scavenger strong.
Following examples are intended to illustrate the present invention, are not that it is limited.
