Abstract

The invention discloses an entrapment agent for selectively lowering crotonaldehyde content in cigarette smoke, which is obtained by mixing propylene glycol and glycerol at the volume ratio of 1:3 to 3:1 and then uniformly stirring. Meanwhile, the invention also discloses a filter stick with the entrapment agent, and the filter stick is prepared by adopting the following steps: (1) the entrapment agent is dissolved in plasticizer glycerol triacetate for forming tows, and during dissolution, the entrapment agent is 6-18% of the glycerol triacetate by mass percent to obtain an entrapment agent and glycerol triacetate mixed solution; and (2) in the tow forming process, the entrapment agent and glycerol triacetate mixed solution is sprayed to be added into a filter stick, and the additive amount of the entrapment agent is 0.01-0.5 mg so as to obtain the required filter stick. According to the invention, the crotonaldehyde content in the cigarette smoke can be remarkably lowered, meanwhile, the cigarette smoke moisture can be maintained, the smoke humidification is enhanced, the smoke quantity and the smoke quality are both improved and a cigarette is endowed with a better smoking feeling. The method and the formula are simple, the raw material source is wide and the cost is low.

Description

The trapping agent of crotons aldehyde and filter stick in selectivity reducing cigarette fume
Technical field
The present invention relates to technical field of cigarettes, refer to particularly trapping agent and the filter stick of crotons aldehyde in a kind of selectivity reducing cigarette fume.
Background technology
Aldehyde compound is one of main gaseous component in cigarette smoke.Wherein low grade aldehyde has strong impulse smell, and along with the increase of molecular weight, penetrating odor reduces, and has produced gradually fragrance.Studies show that, low grade aldehyde in cigarette (main nail aldehyde, acetaldehyde, methacrylaldehyde and crotonaldehyde etc.) there is the toxicity of cilium, sense organ and the respiratory system of stimulation human body that can be in various degree in cigarette smoking process, long-term suction meeting causes more serious harm to human body.
A part of aldehyde and the ketone result that seemingly tobacco directly shifts in flue gas gas phase, however triglycerides when most of this class volatile compound is smoking from precursor (as sugar, pectin, protein) and tobacco forms.At least from gas phase, identified at present 20 kinds of aldehyde and 6 kinds of ketone, these volatile carbonyl compounds particularly formaldehyde, methacrylaldehyde and crotonaldehyde are the toxin of cilium, after sucking together with HCN and NH3, suppress the excremental removing of lung, thereby cause PUD D, meanwhile, formaldehyde also can bring out rhinocarcinoma.
2009, Zhengzhou tobacco research institute is thanked on the basis of sword equality 29 kinds of harmful components (comprising 4 kinds of TSNAs, 3 kinds of PAHs, 8 kinds of carbonyls, 7 kinds of aldehydes matters, HCN, NO, NOx, NH3, CO, nicotine and tar etc.) and 4 kinds of toxicologic index (mouse sucks anxious malicious test, cell toxicity test, Salmonella reversion test and cell micronucleus test) in the main flume of having analyzed 163 cigarette samples, has set up the functional relation of harmful ingredients in flue gas and toxicologic index.By adopting without information variable elimination method and genetic algorithm, filtered out the most representative 7 kinds of cigarette smoke harmful components, i.e. CO, HCN, NNK, NH3, B[a] P, phenol and crotonaldehyde.Burst size based on 7 kinds of harmful components in cigarette mainstream flue gas, has set up a kind of new cigarette smoke harmfulness index.
Based on above research background, the research that reduces crotonaldehyde is an important field of research in cigarette technology.At present, the technology of the reduction crotonaldehyde of mainly taking is mainly adsorption technology and ventilation dilution technology, comprising: utilize containing charcoal filter tip and from cigarette smoke, remove some volatile aldehyde and ketone, thereby greatly reduce the toxicity of flue gas to cilium; To filter tip punching, increase the ventilation dilution rate of cigarette, also can reduce volatile aldehyde.The medium effect of having studied aldehyde material in silk fiber adsorption filtration cigarette main flume is protected in field, with silk fiber, prepare cigarette filter, then by smoking-simulating and collection main flume, by the amount of the content of aldehyde material in colorimetric method for determining cigarette main flume and the aldehyde material of filter tip absorption.Result of study shows: filter-tip silk fiber packed density is larger, in main flume, the content of aldehyde material is lower, aldehyde matter content in filter tip acetone leachate is higher, illustrates that silk fiber has very significantly effect in adsorption filtration cigarette main flume aspect aldehyde material.
But above technology exists the selective and specific aim that cannot realize crotonaldehyde to reduce, in absorption and dilution crotonaldehyde, other material in flue gas and a lot of important aroma component are also adsorbed and diluted, cause flue gas thin out, exhaust gas volumn and flue gas matter decline, and have had a strong impact on cigarette smoking quality.
Summary of the invention
Above-mentioned deficiency for prior art, the trapping agent and the filter stick that the object of this invention is to provide crotons aldehyde in a kind of selectivity reducing cigarette fume, it and crotonaldehyde can produce aldol reaction, while applying in ensureing cigarette on safe and harmless basis, react with crotonaldehyde, crotonaldehyde in flue gas is retained down, reaches the effect that reduces cigarette harm.
For achieving the above object, the trapping agent of crotons aldehyde in selectivity reducing cigarette fume provided by the invention, is characterized in that: it is propane diols and glycerine to be take to the ratio that volume ratio is 1:2.5 ~ 2:1 allocate, and is uniformly mixed to form.
The present invention also provides a kind of filter stick with above-mentioned trapping agent, and its special character is: it is prepared by following steps:
(1) trapping agent is dissolved in to wire-beam forming with in plasticizer triacetyl glycerine, during dissolving, to account for the mass percent of triacetyl glycerine be 6 ~ 18% to trapping agent, obtains trapping agent and triacetyl glycerine mixed solution;
(2) in wire-beam forming process, spray trapping agent and triacetyl glycerine mixed solution adds in filter stick, the addition of described trapping agent is 0.01 ~ 0.5mg, makes required filter stick.
Propane diols and glycerine are humectants conventional in cigarette, can play effective maintenance flue gas moisture, increase flue gas moist feeling, improve the soft degree of flue gas, reduce the irritating effect of cigarette smoking.After propane diols and glycerine are allocated according to a certain percentage, use it in cigarette filter rod, not only can further keep flue gas moisture, improve flue gas suction quality, can also effective selectivity reduce crotons aldehyde in flue gas, reduce cigarette smoking harm.
Consumer is when cigarette smoking, and flue gas passes through the trapping agent in filter stick, the crotonaldehyde generation aldol reaction in the propane diols in trapping agent and glycerine and flue gas, and effectively catching crotonaldehyde, has reduced cigarette smoke harm.
The invention has the advantages that:
1, trapping agent of the present invention can with flue gas in crotonaldehyde produce aldol reaction, the crotonaldehyde in effectively catching flue gas, realizes the object of elective reduction crotonaldehyde after the ratio that deduction tar changes.
2, in trapping agent, alcohols used is all good humectants of effect conventional in cigarette, can keep the moisture of flue gas to exceed lost, improves moist feeling and the mildness of flue gas, reduces dry sensation and excitant that suction produces.
3, trapping agent adding technology process of the present invention is simple, and raw material sources used are extensive, with low cost, easy to utilize.
