Description

A kind of arghan element packaging film with antibiotic effect and preparation method thereof
Technical field
The present invention relates to arghan packaging film technical field, particularly relate to a kind of pineapple leaves fibre with antibiotic effect Dimension element packaging film and preparation method thereof.
Background technology
With cellulose as raw material, the different macromolecule member material of processability is at necks such as medical science, biology and food medicine Territory plays an important role, and has become as the focus of current research.China often produces substantial amounts of Fructus Ananadis comosi per year, and arghan has The health-care effecies such as antibacterial, smelly eliminating, utilize arghan to prepare macromolecule member material and have huge development prospect.Pineapple leaves is fine The fiber macromolecular alignment of dimension crystallization song is neat, regular, and the polyhydroxy structure of fiber molecule and strong hydrogen bonding effect make it clean Cleanliness and the degree of orientation are higher, and chemical reactivity is low, thus cause its application to be restricted." the agriculture in south such as Wei Xiaoyi, Yang Qin Journal ", 2016,47(1): 101-106 " arghan element film preparation process optimization " utilizes emulsifying cut mode to make pineapple leaves Cellulose dissolution improves the chemical reactivity of arghan in ionic liquid, it is achieved the preparation of cellulose membrane, specifically does Method is: be ground into cotton shape with Universalpulverizer after first being dried by arghan element, and alkali processes and acid treatment realizes it respectively Purification process, is then being placed in together with ionic liquid in mulser, is carrying out shear treatment, acquisition prepare the cellulose of film from Sub-liquid homogeneous phase solution, is layered on homogeneous phase solution on the carrier scribbling politef afterwards, through casting solution (glycerol, second Alcohol) etc. soak drying and forming-film；This process technique improves the chemical reaction activity of arghan element, improves the equal of coating solution Phase, but operate and employ substantial amounts of acidizer and alkali inorganic agent, adds somewhat to pollute, add Fructus Ananadis comosi Leaf fibre element film preparation cost, the cellulose membrane function singleness simultaneously prepared.Nano-cellulose have high-crystallinity, high intensity, The excellent properties such as high-specific surface area, environmental friendliness and low cost, also exist substantial amounts of-OH in its molecular structure, with other skies So macromole is easily formed intermolecular and intramolecular hydrogen bond when being blended, and when being used for making membrane material, can make the formation of intermingling material Membrane structure more stable.Gamma-polyglutamic acid-(γ-PGA) is the homopolymer of glutamic acid, is a kind of water soluble polymer, by D- Glutamic acid or Pidolidone form, by alpha-amido and γ-carboxyl, the anionic polymer that γ-amido link is combined into, and have The feature features such as good biocompatibility, good water solubility, degradable, edible, film property, as the life of a kind of new green environment protection Thing material receives much concern, but readily soluble because meeting water, and certain degree limits its application.Micro-nano bubble refers to that diameter is between micron Bubble (bubble of a diameter of 10-50um in water body) and nano bubble (a diameter of bubble less than 200nm in water body) it Between bubble, have big specific surface area, can in water body the time of staying long, and micro-nano bubble is when shrinking, it is possible to Producing substantial amounts of hydroxyl radical free radical, these substantial amounts of hydroxyl radical free radicals can attract the hydrogen in arghan element to a certain extent Key, plays equivalent acidifying alkalization and destroys the effect that hydrogen bond is identical, the nanorize promoting arghan is improved its chemical reaction Activity has certain facilitation.
The fibrous membrane that arghan based on modified gamma-polyglutamic acid-and high chemical reactivity combines is to improving Fructus Ananadis comosi Comprehensive utilization and the abundant packaging film kind of leaf are significant.
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 arghan with antibiotic effect Element packaging film and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of arghan element packaging film with antibiotic effect, including following parts by weight of component: arghan 100- 102, endo cellulase 6-7, chitosan 69-70, nano zeolite powder 3-4, sodium citrate 3-4, appropriate glycerol, appropriate Water.
A kind of arghan element packaging film preparation method with antibiotic effect, comprises the following steps:
(1), will arghan dry after become cotton shape by pulverization process 30min in Universalpulverizer, afterwards and sodium citrate And the water mixing and stirring of gross weight 2-3 times to obtain slurry standby；
(2), by the water mixing and stirring of nano zeolite powder, endo cellulase and gross weight 1-2 times, it is spray-dried to change The high temperature resistant endo cellulase of property is standby；
(3), the slurry that step (1) obtains is heated to 80 DEG C, and be continuously added into modified, high temperature resistant endo cellulase mixing stir Mix enzymolysis 40min, after 100 DEG C of enzyme denaturing, use funnel sucking filtration, obtain modified arghan element standby；
(4) modified arghan element, chitosan and the water mixing and stirring of gross weight 2-3 times, by step (3) are obtained, Being then placed in the mulser with intense ultrasonic wave carrying out ultrasonic assistant emulsifying shear treatment 40min, to obtain homogeneous membrane solution standby With, wherein ultrasonic power 1000W, emulsifying shear rate 15000r/min；
(5), homogeneous membrane solution is layered on the corrosion resistant plate scribbling politef, after cooling molding, uses ethanol solution Soak 2h at 40 DEG C, take out, cool drying and get final product.
The invention have the advantage that the present invention uses the arghan of enzyme pretreatment and chitosan to prepare antimicrobial packaging Film, has good antibiotic property, stretch-resistance and barrier, its hot strength and elongation at break be respectively 7.4MPa and 19.1%, in the preparation process of film, by means of the enzyme that nano zeolite powder is modified, decrease traditional fibre element soda acid purification process The pollution caused and expense cost, it is achieved that environmental protection produces；Furthermore, ultrasonic assistant emulsifying shear treatment one step achieves The further nanorize of arghan and coating solution homogeneous, the micro-nano bubble that ul-trasonic irradiation produces is in coating solution Existence, the dissolving of the material promoting coating solution is homogeneous, decreases conventional homogeneous liquid preparation process intermediate ion liquid Use；On the one hand the nano zeolite powder used improves the heat-resisting quantity of enzyme, contributes to the enzymolysis under high temperature, improves enzymolysis Efficiency, on the other hand, as one of filmogen, nanostructured material further increases barrier and the tension of membrane material Stretching property.
Detailed description of the invention
A kind of arghan element packaging film with antibiotic effect, including following parts by weight of component: arghan 100, endo cellulase 6, chitosan 69, nano zeolite powder 3, sodium citrate 3, appropriate glycerol, appropriate water.
