Abstract
A composite filter tip of cigarette for decreasing the gas-phase free radicals in the smoke of cigarette is prepared from ferulic acid, sodium hypophosphite and activated carbon through immersing activated carbon in the solution of the first two, drying, applying it to acetate fibres, forming filter tip, and combining it with ordinary filter tip.
Description
Technical field:
Patent of the present invention relates to tobacco product, particularly a kind of composite cigarette filter tip capable of effective reduction cigarette smoke gaseous phase free radical and manufacture method thereof.
Background technology:
Free radical often for having atom, molecule or the ion of unpaired electron, has paramagnetism, and the character of most of free radicals is very active, has very high reactivity, participates in a large amount of chemical reactions.Can produce thousands of compounds behind the cigarette burning, wherein comprise the very high free radical of a large amount of activity.In recent years smoking and health problem are discovered that the free radical in the cigarette smoke is the major reason that gives rise to diseases.Contain stable free radicals such as quinone/semiquinone free radical and polycyclic aromatic hydrocarbon free radical in the cigarette smoke tar, but oxygen reserve in the consumer, and the oxygen radical that the activity of generation is higher is attacked multiple material in the body, causes a series of toxicological effects and multiple pathology.Along with falling updating of burnt technology, the tar content of cigarette reduces significantly at present, and the solid phase free radical also decreases in the tar.The another kind of free radical that contains in the cigarette smoke is a gaseous phase free radical; NO free radical, oxygen radical, alkyl diradical (R) and alkoxy radical (RO) etc. are arranged; wherein mainly be alkyl diradical (R) and alkoxy radical (RO); these radical lifes are short; character is active unusually; can cause the membrane lipid peroxidating by the attack cell membrane, but materials such as coup injury cell and enzyme cause the generation of various diseases such as lung cancer.Because smoke gaseous phase free radical toxicity is bigger, and the content in flue gas does not reduce with the minimizing of tar content, fall tar and can not directly reduce cigarette smoke gaseous phase free radical, and common filter tip can not effectively be removed it, therefore develop cigarette smoke gaseous phase free radical scavenger efficiently, reduce the gaseous phase free radical in the cigarette smoke, will improve the security of smoking greatly, have crucial social benefit.
In order to reduce cigarette smoke gaseous phase free radical, some research institutions and production of cigarettes manufacturer have carried out some researchs both at home and abroad, Chinese patent CN1145206A as BJ Tobacco Factory's application, Tea Polyphenols and vitamin C mixing use are made filter tip, are 26.8% to the cigarette smoke gaseous phase free radical clearance rate; And for example the Chinese patent CN1356072A of Shanghai Tobacco's application is the composite filter tip that additive is made with Tea Polyphenols, pyenogenol and active carbon, can make gaseous phase free radical reduce by 14.8%～23.4%; These methods all use organic substances such as Tea Polyphenols, pyenogenol to remove smoke gaseous phase free radical, but because the antioxidant that is added in the filter tip is with generation effect between solid-state form and the gaseous phase free radical, make that the effect of these organic substances removing cigarette smoke gaseous phase free radicals that antioxidant effect is very strong in solution is not very good, and its stability of removing cigarette smoke gaseous phase free radical can not be guaranteed well.
Summary of the invention:
The purpose of this invention is to provide composite cigarette filter tip capable of a kind of effective reduction cigarette smoke gaseous phase free radical and preparation method thereof.
Through screening constantly, find, when adopting organic oxidation-resistant agent forulic acid and strong inorganic reducing agent inferior sodium phosphate synergy can remove cigarette smoke gaseous phase free radical effectively by multiple combinations of substances test back on the basis of repeatedly experiment for the inventor.Inferior sodium phosphate is a kind of very strong inorganic anti oxidant, and forulic acid is that main source is plants such as samphire asafoetide and Ligusticum wallichii.Forulic acid and inferior sodium phosphate among the present invention are worked in coordination with, and can remove free radical effectively, can suppress peroxidization and radical reaction, and forulic acid can combine the infringement of antagonism radical pair tissues such as diaphragm lipid with biological film phospholipid.The inventor combines these two kinds of materials and active carbon and is applied to remove in the cigarette industry cigarette smoke gaseous phase free radical.And the research of this respect of the present invention there is no report.The experiment proved that, can make cigarette smoke gaseous phase free radical remove effect very effectively with very stable by utilization said components of the present invention.
The binary composite filter tip that the present invention is made up of common fibrous filter candle and reinforced filter stick, activated carbon supported forulic acid and the inferior sodium phosphate that contain in the reinforced filter stick.
Accounting for reinforced filter stick percentage by weight by forulic acid, inferior sodium phosphate, the made composite activated carbon of active carbon is 29.7%～41.4%.
The length ratio of described reinforced filter stick and common cellulose acetate filter rod is 1: 1～2: 1.
Test after deliberation, forulic acid and inferior sodium phosphate account for to following weight than the time, can reach the effect of better removing cigarette smoke institute phase free radical.
The content of forulic acid and inferior sodium phosphate is respectively 0.06%～1% and 0.9%～3.3% of this composite cigarette filter tip capable weight by weight.
And forulic acid and inferior sodium phosphate account for to following weight than the time, the cigarette smoke gaseous phase free radical clearance rate can reach 29.4%.
The content of forulic acid and inferior sodium phosphate is respectively 0.3%～0.5% and 1.5%～1.8% of this composite cigarette filter tip capable weight by weight in the described composite filter tip.
Preparation method of the present invention is:
Active carbon is fully immersed in forulic acid and the ortho phosphorous acid sodium solution, makes it to be uniformly dispersed, obtain composite activated carbon after the drying; With this composite activated carbon on the acetate silk that is added on shredding on the filter-stick forming device equably and roll-forming make reinforced filter stick, to make reinforced filter stick and the compound binary composite filter tip that makes of common cellulose acetate filter rod, a kind of composite cigarette filter tip capable of effective reduction cigarette smoke gaseous phase free radical.
The present invention is a kind of composite cigarette filter tip capable that can effectively reduce cigarette smoke gaseous phase free radical.It is dispersed in free radical scavenger on the active carbon, can make the abundant haptoreaction of scavenger and flue gas, favourable and performance antioxidation.Forulic acid is a kind of good natural, phenolic hydroxyl group on its phenyl ring can be removed free radical, suppress peroxidization and radical reaction, and inferior sodium phosphate is a kind of very strong inorganic reducing agent, be very easy to the flue gas gas phase in the very strong unstable radical reaction of oxidisability, it is lost activity.The mutual coordinative role of these two kinds of materials of forulic acid and inferior sodium phosphate can be stablized and remove cigarette smoke gaseous phase free radical effectively, makes the flue gas free radical lose the activity of biological substances such as damaging cells, reduces the harm of smoking cigarette to human body.The cigarette that has adopted composite filter tip of the present invention to make, cigarette smoke gaseous phase free radical can reduce by 20.6%～29.4%.In addition, the present invention can keep stable in removing gaseous phase free radical effect in longer a period of time, the cigarette smoking process does not produce peculiar smell, can meet cigarette product requirement suction preferably distinguishes the flavor of, the products in circulation process has the particularity of certain hour, adopt binary composite filter tip of the present invention, its production cost is low, is applicable to the cigarette product suitability for industrialized production fully.
