Description
Technical field
The present invention relates to Food Packaging technology field, particularly relate to a kind of antibacterial food packaging with food fresh keeping function
Material and preparation method thereof.
Background technology
Microorganism volume is small, of a great variety, breeding rapidly and adapts to the ability of environment by force, the widest in distributed in nature
General.Major part food nutritious, moisture is high, it is easy to caused putrid and deteriorated by the pollution of microorganism, significantly
Shorten the shelf-life of food.The microorganism how preventing food is polluted, and the shelf-life of prolongation food is always the whole world and is correlated with
Scientist's research and the problem paid close attention to.Along with the development of science and technology, utilize packaging material for food prepared by antimicrobial technology
The most more can become a kind of practical and reliable antibacterial scheme.
In the last few years, along with going deep into and the expansion of Application of micron of nanotechnology research, application nano material realized
Antibacterial functions has become current current research focus." nano-ZnO/LDPE antibacterial food packaging material are developed " literary composition is with low close
The strong antibacterial action Nano-class zinc oxide that has of activation processing, as the base material of packaging for foodstuff, is passed through melting blending by degree polyethylene
Method is added in base material, then through single screw extrusion machine and inflation film manufacturing machine, the pellet of gained is blow molded into thin film, i.e. prepares and provides
Having the packaging material of antibacterial functions, result of the test shows: the packaging material prepared can not only extend the shelf-life of food, improves
The safety of food, and the antibacterial that can be effectively prevented between person to person, people and thing, people and food, thing and food is intersected
Infect, give the new implication of packaging for foodstuff and function.
But nano zine oxide Antibacterial Mechanism is photocatalysis antibacterial in literary composition, under there is no light catalysis, effect of food preservation
Difference, shelf life is short, and condition is harsh and broad-spectrum antibacterial property is narrow, needs a kind of nontoxic, durable antibacterial effect of interpolation badly and urges without light
The antibacterial compatibility therewith changed；Only have obstruct and defencive function with packaging material for food in eight-legged essay, structure is single, along with food
The importance of packaging material safety constantly rises, and the requirement of packaging material for food is continuously increased by market, it is desirable to can be fresh
Extend the shelf life with the food of high-quality, especially the demand to Active Packaging Materials because it can pass through deoxygenation, antibacterial,
Dehumidifying, the pack environment of material internal of changing package except modes such as ethylene, release ethanol, prevent the growth of microorganism, Jin Erti
The shelf-life of high food, thus be necessary prior art is modified.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of antibacterial food with food fresh keeping function
Product packaging material and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of antibacterial food packaging material with food fresh keeping function, are prepared by the raw materials in: low density polyethylene
Alkene 100, nano zine oxide 2.5-3.3, cinnamon essential oil 5.1-5.7, straw ashes 2-4, carbic anhydride 2.4-2.7, high fructose syrup
Slurry 3-5, copper 8-quinolinolate 1.2-1.5, citric acid 0.9-1.3, Melia azedarach L. wood powder 3-5, MTES 5.9-6.4,
Suitable quantity of water.
The manufacture method of described a kind of antibacterial food packaging material with food fresh keeping function, comprises the following steps:
(1) citric acid is added suitable quantity of water and is heated to 80-95 DEG C of stirring to all dissolving, keep constant temperature to add nano zine oxide,
High-speed stirred back flow reaction 1-2 hour, filtering and washing is to neutrality and dries, and adds cinnamon essential oil and puts in mixer, with
The rotating speed high-speed stirred of 10000r/min obtains modified nano zinc oxide in 30 seconds；
(2) straw ashes, Melia azedarach L. wood powder being ground uniform 120-140 mesh sieve excessively, at 570-590 DEG C, activation processing 20-30 is divided
Clock, be cooled to room temperature add MTES, copper 8-quinolinolate ultrasonic disperse 40-50 minute modified straw ash
Cinder；
(3) by step (1), (2) reaction mass stirring and evenly mixing, ultrasonic grinding 10-15 minute, add Low Density Polyethylene and other
Residual components mixes, and puts into melt blending, pelletize in double screw extruder, obtains packaging pellet；
(4) the packaging pellet blowing obtained in step (3) is made the thin film of thickness about 70-90 μm, discharging.
The invention have the advantage that the present invention with Low Density Polyethylene as base material, by receiving after silane coupler activation processing
Rice zinc oxide, as photocatalysis antibacterial agent, makes the organic principle such as antibacterial, moisture be decomposed, thus kills or bacteria growing inhibiting,
And compound cinnamon essential oil, even if still having stronger antibacterial and mouldproof performance under conditions of unglazed, broad-spectrum antibacterial property is high；Simultaneously
Adding modified straw ashes as filler, adsorptivity is strong, by deoxygenation, dehumidify, change package material except modes such as ethylene
Internal pack environment, prevents the growth of microorganism, degradable low cost, utilizes the antibacterial food packaging material that the present invention prepares
There is good fresh-keeping effect, make food at not adding preservative agent, without having the longer shelf life phase in the case of cold preservation.
