Description
Technical field
The present invention relates to a kind of cigaratte filter and its filtering materials, living more particularly, to a kind of biology for cigaratte filter
The preparation method of property protein material, and it is applicable in the filter tip of the biological activity protein material.
Background technique
Through official confirmation, at least 5289 kinds of ingredients in tobacco and cigarette smoke, harmful components are 149 kinds, and complete at present
Ball medical field is consistent with tobacco business to approve and concerns main 46 kinds of ingredients therein.The tobacco factory in the whole world is all researching and developing and is creating
This project of new lowering harm and decreasing coking, but technology not especially desirable so far.Growing to even greater heights and consuming with world's Anti-smoking activity
Generally enhancing of the person to smoking and health concerns, requirement of the market to cigarette is higher and higher, and the pressure that tobacco faces is increasingly
Greatly, especially some countries have required to mark and reduce harmful substance listed in Hoffmann list, therefore, tar reduction in recent years
Harm reduction is the development trend of domestic and international tobacco.The tar and tool harmful components for how making cigarette significantly reduce, while keeping again
Cigarette odor-absorbing makes consumer obtain physiology satisfaction, is the maximum challenge that Cigarette design faces.
Filter tip is a kind of filtrating equipment of flue gas being installed in cigarette, is played an important role in cigarettes reduce coke damage.Mesh
It is preceding domestic generally using vinegar is fine or the third fine common filter tip, and have that selectivity is high, functional filter-tip of excellent adsorption is using less.
Currently, the technological means generallyd use is: in common filter tip material, active carbon, the silicon of single addition porous high surface area
Barbiturates (active carbon is lower to the adsorption capacity of polar substances and carbon monoxide) or bioactive extracts (it is more complicated, with
The reaction of flue gas it is difficult to predict).Selectivity, efficiency, complexity, cost control etc. of this several substance in absorption harmful substance
Aspect is different, especially in selectivity, it is difficult to really realize it is larger while harmful substance is greatly decreased, keep it is original
Cigarette perfume and taste is sucked, this is particularly important in the domestic market mainly based on flue-cured tobacco, and market reaction is very sensitive in this respect.
In addition, the vinegar fibre ingredient of general filter tip is difficult to degrade, certain harm is caused to environment.In short, as national governments are to volume
The limitation of cigarette is increasingly stringenter and consumer is increasingly enhanced smoking and the concern of health, and sucks the demand of taste, only
It has been difficult to meet the growth requirement of cigarette market with a kind of Special Cigarette Filter of single function additive, that is to say, that Special Cigarette Filter is
Developed from a kind of additive single function to the multi-functional direction of multiple additives.In addition, cigarette consumption person is sucking volume for a long time
It is close heated due to being contacted with combustion parts when cigarette, and influenced by smoke components, the cell of oral cavity especially lip be easy by
It corrodes, oxidation, fibrosis, Yi Yinfa lesion.
Summary of the invention
One aspect of the present invention discloses a kind of preparation method of biological activity protein material for cigaratte filter,
Be characterized in that the following steps are included:
(1) protein gene merges
By new blood at 10 DEG C, it is centrifugated 2 minutes by the speed of 500r/min, then with the speed of 2000r/min
Centrifuge separation 10-12 minutes, takes third layer liquid i.e. haemoglobin liquid；Isolated haemoglobin liquid is sent into aseptic experiment room,
α chain and albumen β chain are isolated with sequenator and Peptide synthesizer, amino acid sequence analysis instrument, is closed by cell fusion apparatus
At bioprotein；
(2) albumen culture
The bioprotein of fusion is sent into albumen slot, in be added in albumen slot the distilled water of 2 times of quality of bioprotein into
Row culture cultivates 30 DEG C of temperature, and blowing air amount is 0.8 times of volume of albumen slot, cultivates 2h, and biological egg then is added to sedimentation basin
80 times of white matter amount of tryptose soya agar culture medium；
(3) chelatropic reaction
The activated carbon that partial size is 40-60 mesh is added into sedimentation basin, is kept for 10 DEG C of temperature, and 90rpm is stirred 20 minutes, makes to live
Property carbon is sufficiently merged with albumen, after the completion of chelatropic reaction is abundant, takes supernatant liquor；Wherein it is public to be added 5 for 1 kilogram of bioprotein
The coconut shell activated carbon of jin；
(4) carrier embeds
Supernatant liquor is added in Bacillus acidi lactici selectivity agar, 10 DEG C of Yu Wendu, after cultivating 24 hours, enters back into zero
Lower 40 degree freeze 24 hours, hence into dormant state, by the protein fusion particle of process dormant state or protein fusion liquid into
