Description

A kind of preparation method of the biodegradable food package film of high-performance
Technical field:
The present invention relates to the preparation field of a kind of food package film, be specifically related to a kind of biodegradable food of high-performance The preparation method of packaging film.
Background technology:
The economic construction that develops into of packing business is made that contribution, but on the one hand product packaging consumes ample resources, the opposing party Bread dress residue is but the polluter that can not be ignored, and brings serious environmental problem, and vast majority of people thinks packaging The environmental pollution brought is only second to water pollution, ocean lake pollution and air pollution, is in the 4th.According to estimates, the whole world The rubbish quantity abandoned every year is close to 10,000,000,000 tons, and packaging waste just account for about 1/3, then account for 1/2 from volume, this A little garbages not only consume resource, and occupy great space and expend a large amount of processing cost, the most many packagings The material of thing is non-degradable material, in meeting longer-term persistence environment, causes environmental pollution, has a strong impact on ecological balance.Packaging with Environmental protection is just being put in face of people as a social hotspots, it has also become the serious problems solved are badly in need of in various countries.Therefore, green package Being the common need of survival and development of mankind, development green package is the inevitable choice of 21 century.
Green package refers to harmless, of low pollution, meets all kinds of packaging article of environmental requirement, including environment and resource Implication of both regeneration.Green package in the strategy of sustainable development requires the design of product packaging, manufactures, uses and process The requirement of the ecological environmental protections such as low consumption, decrement, of low pollution all should be met.Green Package Technology is used in food, permissible Promote national economic development, the most also provide a practicable approach for solution food pollution.Thus, packaging for foodstuff should Pay much attention to environmental protection and ecological balance problem.The feature of green package be pollution-free, can reclaim or regenerate, easily decompose.Green bag The development trend of dress is degradable environmentally friendly packing material and edible packing material.
The edible packaging resource of exploitation the most both at home and abroad is extensive, and research and development prospect ten people is optimistic.Its research and development Major domain polysaccharide edible packing membrane, protein-based edible packing membrane, microorganism copolyester edible packaging with And the aspect such as polysaccharide, protein, fatty acid complex mould assembly edible packing membrane.Edible with vegetable polysaccharides or animal polysaccharide as substrate Property packaging mainly have starch film, modified cellulose film, animals and plants glued membrane, chitosan film etc..But the packaging film studied at present Have that heat stability is bad, the shortcoming of poor mechanical property.
Summary of the invention:
It is an object of the invention to provide the preparation method of the biodegradable food package film of a kind of high-performance, the method prepares Food package film biological degradability good, thermal stability is excellent, and mechanical property is good.
For achieving the above object, the present invention is by the following technical solutions:
The preparation method of the biodegradable food package film of a kind of high-performance, comprises the following steps:
(1) collagen protein is dissolved in deionized water, is subsequently adding cross-linking agent, keep solution temperature to be 2-10 DEG C, stirring Mixing 20-30h, obtains modified collagen protein solution；
(2) modified collagen protein solution is warming up to 60-70 DEG C, is sequentially added into sodium alginate, carboxymethyl cellulose, modification Starch, glycerol, then stirring insulation 30-60min, obtains pasty state mixed liquor；
(3) using power is the microwave of 140-600W, and point pasty state mixed liquor prepared step (2) 2-4 time carries out irradiation, Variations in temperature interval is 30-60 DEG C, is incubated 10-30min after being warming up to fixed value every time；
(4) the pasty state mixed liquor after microwave treatment is placed in deaeration machine removing bubble, is subsequently poured into die for molding, It is dried at temperature 80-120 DEG C, 10-20 hour, takes off film and obtain the biodegradable food package film of high-performance.
Preferred as technique scheme, described cross-linking agent, collagen protein, deionized water, sodium alginate, carboxymethyl are fine Dimension element, modified starch, the mass ratio of glycerol are (0.05-1): 2:(50-80): (2-3): (0.5-1.5): (1-2).
Preferred as technique scheme, described cross-linking agent is metal salt crosslinking agent and the one of Polyphenols cross-linking agent.
Preferred as technique scheme, described metal salt crosslinking agent is chromic sulfate, chromium sulfate basic, aluminum sulfate, sulfur One in acid titanium and Disulfatozirconic acid..
Preferred as technique scheme, described Polyphenols cross-linking agent is rubber tannin, Baybery tannin, chaste tree Tannins From Barks With the one in larch tannin.
Preferred as technique scheme, described modified starch is cyclodextrin, maltodextrin, amylose, methyl One or more mixing in the isocyanate-modified starch of acrylic acid 2-, hydroxypropyl PASELLI EASYGEL.
The method have the advantages that
The microwave that the present invention selects power to be 140-600W carries out microwave treatment, and when microwave power is less than 140W, microwave is anti- Answer device not to be provided that stable microwave power output, when microwave power is higher than 600W, cause reaction system owing to heating too fast Temperature exceedes the phenomenon of design temperature, and material can cause irreversible damage；
The present invention uses suitable microwave treatment, can be effectively improved the heat stability of material, but also so that pole Property material in the electromagnetic field of high frequency conversion produce instantaneous dipole, cause polarity to increase, promote the generation of cross-linking reaction, and Add the effect of cross-linking reaction；
The packaging film excellent in mechanical performance that the present invention prepares, biodegradability is good, and preparation method is simple, process conditions Gentleness, low cost.
