Description
Technical field：
The present invention relates to berry fresh-keeping film-coating field of material technology, more particularly to a kind of fresh-keeping packaging of chitosan containing decanoy acetaldehyde
Film and preparation method.
Background technology：
Coating-film fresh-keeping refers to the material with film forming applying upper on berry surface by modes such as sprinkling, dipping, brushings
One layer of very thin film, so as to suppress the gas exchanges of fruits and vegetables, reduces respiratory intensity, reduces the evaporation of moisture, reduces disease
Opportunistic pathogen directly infects to berry, preferably maintains the freshness and hardness of berry, reaches and delay berry putrid and deteriorated, make slurry
Fruit keeps the preservation technology of certain freshness.Because its have the advantages that simply, conveniently, cost is low, effect is good, easy to spread,
Have become an active research field of comparison both at home and abroad.
Find that it has inorganic particulate and metallic, especially nanoscale in current chitosan antistaling agent application process
Other inorganic particulate and metallic in polymeric matrix disperse it is uneven, into membrane structure it is poor the problem of, so as to cause it
Block-water performance is poor in preservation process, fruit vegetable nutrient ingredients from lossing is very fast.Meanwhile, this kind of compelx coating material needs to add other
Cosolvent or coupling agent, or core shell structure is made by the method for chemistry, its composition is relative complex, and edible safety is poor, system
Standby process is cumbersome, and has an effect on the final performance of compelx coating material.
The content of the invention：
Present invention aim to address existing fresh-keeping film-coating is odorous and preservation process in water preventing ability is poor, fungistatic effect is poor, battalion
The problem of ingredients from lossing is very fast is supported there is provided a kind of film forming compact structure is homogeneous, water preventing ability and biocidal property are good compared with strong, mechanical strength,
Suppress berry gas exchanges, reduction respiratory intensity, reduce moisture evaporation, reduce pathogen to berry directly infect contain
Decanoy acetaldehyde chitosan fresh-keeping packaging film and preparation method.
Above-mentioned purpose is realized by following technical scheme：
A kind of fresh-keeping packaging film of chitosan containing decanoy acetaldehyde, its composition includes:Chitosan, gelatin, glycerine, cordate houttuynia, it is described
The parts by weight of chitosan are 1.7, and the parts by weight of described gelatin are 1.2, and the parts by weight of described glycerine are 0.3, institute
The parts by weight for the cordate houttuynia stated are 20-60.
The described fresh-keeping packaging film of chitosan containing decanoy acetaldehyde, described chitosan is amphipathic chitose derivative and parent
One kind of aqueous chitosan derivatives, described amphipathic chitose derivative is to complete methyl dodecyl chitosan, complete methyl
Oleoyl chitosan, light propyl group cetyl-chitosan or oleoyl chitosan season cut with scissors any one in salt, described hydrophily shell
Polysaccharid derivative is to complete the one kind for cutting with scissors salt in methyl chitosan, light propyl group chitosan or chitosan season.
A kind of preparation method of the fresh-keeping packaging film of chitosan containing decanoy acetaldehyde, this method comprises the following steps：
（1）The cordate houttuynia bought is dried after cleaning at a temperature of 65 °C, is then smashed with pulverizer, cordate houttuynia is shredded with knife,
Then add 70% ethanol solution；
（2）The ethanol solution for adding cordate houttuynia is extracted into filter 23 after 2h in 40 DEG C of waters bath with thermostatic control, filtrate rotary evaporation is extremely
1g/mL；
（3）It is Herba Houttuyniae extract that filtrate is prepared into 20-60g/100ml by solvent of distilled water；
（4）Chitosan, gelatin, glycerine are prepared to 1.7g/100ml chitosan solution, 1.2g/ by solvent of distilled water respectively
100ml gelatin solution and 0.3g/100ml glycerite；
（5）The chitosan solution of same volume, gelatin solution, glycerite and Herba Houttuyniae extract are mixed respectively
Multiple preservative solutions；
（6）The Multiple preservative solutions configured are subjected to atomizing coating problems to berry, the surface of berry is just soaked completely
For standard, air-dry it at a temperature of 10 °C, the surface of berry is formed one layer of antibacterial preservative film.
Beneficial effect：
1. preparation method of the present invention is simple, easy to operate, pass through specified raw material, proportioning and order of addition so that the material finally prepared
Expect that homogeneous film forming compact structure, water preventing ability and biocidal property are good compared with strong, mechanical strength, not only have suppression berry in berry is fresh-keeping
Gas exchanges, reduction respiratory intensity, the evaporation for reducing moisture, reduce directly infect etc. effect of the pathogen to berry, and
The loss of nutritional ingredient can be reduced, fresh-keeping effect is improved.
Cordate houttuynia, also known as the folding basal part of the ear are added in the present invention, is gained the name because fresh grass has a fish like smell, cordate houttuynia is traditional simply
Active ingredient in Chinese medicine, all herbal medicine, cordate houttuynia is decanoyl acetaldehyde (negative raw meat grass element) and methyln nonyl ketone (methylnonanone).
There is the lower present invention that acted synergistically after addition cordate houttuynia antibacterial, antiviral, raising immunity of organisms, resolving sputum, diuresis, anticancer etc. to make
With.
The chitosan added in the present invention is a kind of polysaccharide large biological molecule of polycation, from chitin
Partially deacetylated, chitosan belongs to edible natural material, direct-edible, and its bacteriostasis property is stronger, after the present invention is added
Liquid surface formation shell membrane, can prevent the intrusion in storage period miscellaneous bacteria in process, in addition, chitosan is also with penetrating
Property and moisture retention, prevent the characteristics such as brown stain, simultaneously as crude antistaling agent in the present invention, can effectively suppress various germs invasions and
Growth.
The present invention, using hydrophily chitosan derivatives as matrix, adds using specific polymer shell polysaccharid derivative as raw material
Plus antibacterial material decanoy acetaldehyde, chitosan film is possessed antibacterial and think performance, slow down berry moisture scatter and disappear and it is rotten.
Fresh-keeping atomizing film effect prepared by the present invention is good, and being applied to berry coating-film fresh-keeping can significantly protect
Protect the color and luster of berry and reduce rotting rate, with stronger fungistatic effect, and berry Vc in storage loss can be suppressed
With acidity reduction, it can significantly extend the fresh keeping time of berry at 4 DEG C.
Not only technique is simple, easy to operate, environmentally friendly, pollution-free for the preparation method for the class coating material that the present invention is provided, Er Qiesuo
Material is chitosan derivatives, its edible safety, and anthocyanidin, TSS, Vc, PPO enzyme, titratable acid are all contained in berry
Content, MAD, this several material play decisive role to the freshness of berry, and berry all regular shapes are easy to spraying, because
This present invention is applied to the fresh-keeping of all berries.
