About introducing using in the delicious, frozen poultry " The light catalyst " Research report
" light catalyst " It is a kind of nanometer metal oxide material ' The titanium dioxide is commonly more used) ,Its painting, to the surface of substrate, under the function of the light, produce and catalyze and degrade the function strongly: Can degrade the poisonous harmful gas in the air effectively; Can kill many kinds of bacterium effectively, and can bacterium or toxin decomposing and harmless treatment that fungi release; Still possess the function of deodorizing, resisting corruptly etc. at the same time. At present, " light catalyst " Has not used in the delicious frozen poultry products publicly, in order to understand " light catalyst " The result used in the delicious frozen poultry products, the technique center, to " light catalyst " That if you can't go on material, materials will collect,combine meat chicken process Company product tube carry on in using by " the light catalysting " on poultries fresh frozen Experimental result,situation analysis as follows:
First, " light catalyst " Summary
" light catalyst " It is the light + catalyst ' Catalyst) Compound word,it is it is with semiconductor material of the photocatalysed function for general name since every one is represented by titanium dioxide.
" light catalyst " As its name suggests regard as the energy source of the chemical reaction with photic energy, utilize titanium dioxide ( TiO2 ) As catalyst, accelerate redox reaction, make, absorb in external oxygen and water molecule stimulate poling have active OH - and O 2 - free radical, these can nearly decompose all to oxidize free radical with extremely strong strength to the human body or environment harmful organic matter and some inorganic substances, enable their oxidize and resolve into the steady and harmless material rapidly ' Water, carbon dioxide) ,In order to reach the scavenging, sterilizes, odor-resistant function.
Second, " light catalyst " Employ the principle
" light catalyst " The titanium dioxide is seen and only can be produced, the negative electron, the positive electron binds with water molecule in the air and produces the oxygen radical of hydrogen, practice has proved, the oxygen radical of hydrogen has strong oxidation that decomposes ability, it can decompose inorganic matter of almost all the organic compounds and a partial inorganic matter, resolve them into nonpoisonous carbon dioxide and water, and the negative electron binds with oxygen in the air and produces active oxygen, oxidize ion superly, oxidizing ion superly has very strong oxidation that decomposes ability too, it can destroy the intersection of bacterium and cell membrane of organic matter the, the intersection of solidification and protein of virus, harmful compound released while sterilizing on the resolving bacterium's corpse. In addition, " light catalyst " Exceeding the hydrophilicity of titanium dioxide, can remove the dust in the body surface, greasy dirt under the aqueous function of light sum, reach the function of self-cleaning.
Third, " light catalyst " Function
1,Scavenging : Because " light catalyst " The hydrogen oxygen radical that the titanium dioxide produces will destroy the organic gas molecular energy key in advance, make the organic gas become the simplex gas molecule, accelerate the organic matter, gaseous resolving, oxidize various organic matter, oxides of nitrogen, sulfoxide and ammonia,etc. such as formaldehyde, benzene in the air, reduce and become the innoxious substance. It can make human body bad smell, animal bad smell and the intersection of cigarette and bad smell is removed, scavenging. Light catalyst titanium oxide can give play to and subdue the fine characteristic such as being discredited, antibacterial, antipollution while contacting the light, especially solving atmospheric environmental deterioration, impact on indoor environment of chemistry in new building material and furniture, at the time of the air pollution scheduling problem which the car exhaust produces, well received by people.
2,Deodorize: " light catalyst " Titanium dioxide than the intersection of ozone and anion, have better oxidation ability; Have stronger adsorption force than the activited carbon, also have unexistent resolving efficiency (decompose bacteria) of activited carbon . " light catalyst " Deodorize ability according to the authoritative laboratory test in American-European countries with titanium dioxide, titanium dioxide of every square centimeter compares with fibrous activited carbon with high capacity and efficiency of every square centimeters, the deodorant ability of the titanium dioxide is 150 times of the fibrous activited carbon with high capacity and efficiency, it is equivalent to 500 pieces of living carbon refrigerator deodorizer.
3,It is corrupt to defend: Prevent tar of cigarette, the generally smeary one is adhered to and the toilet nightstool turns to be yellow; Prevent the metal from getting rusty, prevent the fading of the object applied.
A, destroy cell membrane of cell, make cytoplasm run off, lead to the fact bacterium's death with ultra the intersection of oxidation and ability of titanium dioxide;
B, solidifying protein of the virus, inhibit the activity of the virus, and bacterium of swimming while catching, killing the air, its ability is up to 99.96%;
C, can kill Escherichia coli, green the intersection of suppuration and fungus, Staphylococcus aureus, dark the intersection of song and fungus,etc.;
"anaphylactogen, reduction anaphylactia and asthma in d, detachable air, can also decompose bacteria, improve the tinea pedis situation and and does not injure the skin.
5,Resist the rot and antibacterial: Prevented mucidding and algal and producing, the ones that prevented scale were adhered to.
6,Keep fresh: While keeping fruit and grain, if drib goes bad among them, the miscellaneous part will go bad soon. This is because the already rotten part will release and can promote ripe and aging ethyne gas such as fruit and vegetables, promote other parts to be ripe and wearing out and accelerating the corruption. If use the light catalyst, can resolve ethyne gas into the carbon dioxide and water, enable fruit and grain to keep for a long time, raise the market price of the goods. Put in the strawberry case " The light catalyst " Block makes the strawberry keep fresh or use the device making fruit and grain keep fresh for a long time to already commercialize in places such as the food warehouse,etc.. Use light catalyst decompose the intersection of ethyne and gas, at the same time still can prevent reproduction and deodorant, etc of bacterium and mould,etc. under warehouse from, make products quality stable and releive the job environment while, and make it possible that the blending of different crops is preserved. Can also be used for planting the fungus, spherical save of rhizome at the same time, prevent the yellowing of spinach, garlic,etc.. Utilize this kind of result of the light catalyst, prevent the food corruption, inhibit the discharge of the rubbish, see that make people fix one's eyes on from solving the view of grain problem and waste problem.
Fourth, " titanium dioxide " Operating range and standard in the food
" national standard food additive of food security uses the standard " to stipulate in GB2760-2011: The titanium dioxide is the colourant, use the standard as follows:

Seventh, to introducing using in the delicious, frozen poultry " The light catalyst " Analysis propose
It is knowing to collect material and experiment situation by the above:
1,The regulation of national standard " The light catalyst " The titanium dioxide of main material is not being allowed as food additive the delicious, frozen poultry is being used, if it violates the national food safety standard to use.
2,Introduce using in the delicious, frozen poultry " The light catalyst " Will cause the human body to intake directly " The light catalyst " The material, has not intaked " light catalyst " about the human body now Experiment data,it is unable if you can't judge on poultries fresh frozen, introduce to last " the light catalyst " Endanger the situation to the human body.
3,The company uses " The light catalyst " Try out and test, the result reveals that uses " light catalyst " only in the fresh poultry There are certain results, " light catalyst " under the condition of the illumination to receive The applicable scope is minor.
4,Use " light catalyst " Need to invest the production cost, but can bring the obvious benefit perhaps.
Have technical conditions now according to our company, its actual application ability and result in delicious, frozen poultry keeps fresh that do not possess understanding, need to unite the national large-scale experiment organization and carrying on the deep experiment and proving, even can application, national related departments also sanction, use, the masses of consumer add, store to additive in, misunderstand generally at present in addition. In view of the above-mentioned situations, propose this technology wouldn't introduce.
