Description
Technical field
The present invention relates to food preservation field, more particularly to a kind of compound antiseptic packaging films of food preservation and its preparation
Method.
Background technology
Cold fresh meat, is called chilled meat, refers to strict implement veterinary quarantine system, the poultry trunk after butchering is carried out rapidly cold
But handle, make trunk temperature (using hind shank center as measurement point) is interior when 24 is small to be reduced to 0-4 DEG C, and in following process, circulation
With the fresh meat in the range of 0-4 DEG C is remained in sales process.But the refrigerated storage temperature of cold 0-4 DEG C of fresh meat can not press down completely
The growth and breeding of some cryophiles are made, therefore cold fresh meat shelf life is short, surface brown stain and juice loss are more serious.
The corruption of cold fresh meat can be slowed down cold fresh meat packaging to a certain extent, extend the shelf life of cold fresh meat.At present
The novel package mode of cold fresh meat is mainly vacuum-packed and controlled atmospheric packing.Authorize the middle promulgated by the State Council of Publication No. CN201105860Y
Bright patent gives《A kind of new raw fresh meat thermal contraction freshness protection package membrane》, its main feature is that providing a kind of fresh meat VLDPE/
Viscous/PVA/EVOH/PVA/ glues/LDPE seven-layer structure thermal contraction freshness protections.Authorize the Chinese invention of Publication No. CN1657366A
Patent gives《High oxygen antistaling packaging technology for supermarket fresh meat》, its main feature is that with the salt of 1-3% and the cooking wine of 2-5%
Carry out subtracting antibacterial processing, while using the O of 60-80%2And 20-40%CO2Gas component, loads PP thermoforming bags by cold fresh meat
Mounted box, makees the progress high oxygen modified atmosphere fresh-keeping packaging of packing box cover layer to extend its shelf-life with PA/PE or BOPP/PE composite membranes.
It is contemplated that supermarket's cost input and the operability of supermarket staff, above-mentioned patented method lack reality in the market
Border application.
The corruption of cold fresh meat is largely due to caused by the breeding of microorganism, so providing a kind of tear-use tool
The packaging material for having biocidal property is only needed for market.Antimicrobial packaging is most important one kind in active packing, is by using it
Packaging material with bactericidal effect, suppresses the growth of food microorganisms in storage and avoids the secondary pollution of food, from
And extend the shelf-life of food.Therefore compared with ordinary packing, antimicrobial packaging is to ensuring food security and extending food shelf
The effect of phase is more prominent.
The content of the invention
The present invention provides a kind of compound antiseptic packaging films of food preservation, and the compound antiseptic packaging films are especially suitable for right
The packaging of cold fresh meat, has cold fresh meat preferable antibacterial and Bao Se to act on.
The present invention provides following technical solution：
A kind of compound antiseptic packaging films of food preservation, including the PE film layers and chitosan being bonded to each other/lauramide essence
Propylhomoserin hydrochloride ethanol ester composite nano fiber layer；
In the chitosan/lauramide arginine monohydrochloride ethanol ester (LAE) composite nano fiber layer, chitosan with
The mass ratio of lauramide arginine monohydrochloride ethanol ester is 1~5: 1.
Can mutually it be cooperateed between chitosan and lauramide arginine monohydrochloride ethanol ester in composite nano fiber layer
Effect, makes composite nano fiber layer have a preferable antibacterial effect, at the same the PE film layers of outer layer can stop well cold fresh meat and
The contact of outside air, reduces pollution of the bacterium to cold fresh meat in air.
Preferably, the mass ratio of chitosan and lauramide arginine monohydrochloride ethanol ester is 1~2: 1.
Chitosan and lauramide arginine monohydrochloride ethanol ester ratio the two is mutually cooperateed with antibacterial effect have compared with
When big influence, chitosan and excessive lauramide arginine monohydrochloride ethanol ester mass ratio, due to lauramide arginine salt
The relatively low fungistatic effect of hydrochlorate ethanol ester content does not reach optimum efficiency；Chitosan and lauramide arginine monohydrochloride ethanol ester matter
Amount than it is too small when, due between chitosan and lauramide arginine monohydrochloride ethanol electrostatic interaction formed polymer on the contrary
The biocidal property of compound can be reduced.
There are countless tiny holes in composite nano fiber layer, considerably increase chitosan/lauramide arginine salt
The contact area of hydrochlorate ethanol ester composite nano fiber and cold fresh meat top layer air, improves chitosan and lauramide arginine salt
Hydrochlorate ethanol ester is to the inhibitory action of bacterium in the air of cold fresh meat top layer, the fungistatic effect of raising film entirety.Preferably, it is described
In chitosan/lauramide arginine monohydrochloride ethanol ester composite nano fiber layer, porosity is 65~75%；Form compound receive
A diameter of 120~200nm of the nanofiber of rice fibrous layer.
Present invention also offers the preparation method of the compound antiseptic packaging films of food preservation, comprise the following steps：
(1) chitosan and lauramide arginine monohydrochloride ethanol ester are dissolved in the acid solution that volumetric concentration is 70~90%
In, obtain electrostatic spinning liquid；
The mass ratio of chitosan and lauramide arginine monohydrochloride ethanol ester is 1~5: 1；
(2) by the electrostatic spinning liquid electrostatic spinning to the surface of PE films, to obtain the final product.
The fibre diameter that electrostatic spinning obtains is uniform and controllable, and obtained nano fibrous membrane has higher specific surface area
And porosity, add chitosan/lauramide arginine monohydrochloride ethanol ester composite nano fiber and cold fresh meat top layer air
Contact area, improve its fungistatic effect.
Preferably, in the electrostatic spinning liquid, the mass ratio of chitosan and lauramide arginine monohydrochloride ethanol ester
For 1~2: 1.
The concentration and viscous effects electrostatic spinning process of electrostatic spinning liquid, diameter and form tool to obtained nanofiber
There is large effect.The excessive solution viscosity of chitosan concentration is excessive, and electrostatic spinning process cannot be smoothed out；Chitosan concentration mistake
Hour, the intermolecular company of twining is not enough to successfully carry out electrostatic spinning process.Preferably, in the electrostatic spinning liquid, chitosan
Mass concentration is 30~50g/L.
Preferably, the acid solution is acetic acid solution.Acetic acid contributes to chitosan and lauramide arginine monohydrochloride
The dissolving of ethanol ester, and acetic acid is nontoxic to human body.
Preferably, in step (2), electrospinning conditions are：Electric field strength is 1.5~2.5kV/cm, and it is 10 to receive distance
~15cm, electrostatic spinning flow velocity are 0.25~0.5ml/h.
It is further preferred that used specification of syringe is 5ml during electrostatic spinning, syringe needle is the 20G pins of tack
Head.
Compared with prior art, beneficial effects of the present invention are：
(1) the compound antiseptic packaging films of food preservation of the invention are prepared using electrospinning process, have fiber
Porous structure, therefore the compound antiseptic packaging films have high-specific surface area, and bacteriostatic agent LAE distributions can be made more uniform, carried
The fungistatic effect and fresh-keeping effect of high packaging film entirety；And there is mutually synergistic effect, enhancing is each other between chitosan and LAE
Fungistatic effect；When cold fresh meat carries out fresh-keeping using electrospinning chitosan/PE films, its total plate count 3 days is i.e. exceeded, and uses this hair
When bright packaging film carries out fresh-keeping, the total plate count of cold fresh meat 6 days is not exceeded, and yellowish pink keeps good；
(2) chitosan and LAE are food-grade, and are all biodegradable materials, nontoxic to human body；
(3) the preparation method technique of the compound antiseptic packaging films of food preservation of the invention is simple, suitable for industrial production.
