Abstract
The present invention relates to oxidation resistant edibility synthesized thin film of a kind of antibacterial and preparation method thereof.Curcumin and solubilizer are blended, heated and ultrasonically treated by this method first, then it is uniformly mixed with gelatin, plasticizer solution, regulation mixed liquor pH value is to add cross-linking agent solution after 7 ~ 11, finally dries in injection mould after uniform mixing at room temperature and prepares synthesized thin film.The present invention assigns the oxidation resistant performance of gelatin film antibacterial by adding natural active matter curcumin, and being successfully introduced into for curcumin can promote gelatin materials to show different colors in different pH environments, realize the environmental pH response of gelatin membrane material.In addition, the characteristics of synthesized thin film that the present invention is provided also has extensive raw material sources, good high mechanical strength, water preventing ability, degraded by environment and edibility, it has market potential application value in medicine and food packaging applications.
Description
Technical field
The present invention relates to plastics arts, there is antibacterial, oxidation resistance, mechanical strength in particular to one kind
High, edibility synthesized thin film of degraded by environment and preparation method thereof.
Background technology
The nutriments such as food during the storage easily by environment in microorganism polluted, in turn result in the change of food
Matter and corruption.In addition, ultraviolet present in environment and free radical also can result in the oxidation of the materials such as lipid, its mouth is destroyed
Taste, or even produce some pathogenic, carcinogenic chemical compositions.Therefore, in order to extend preservation time of the materials such as food, medicine, grind
Exploitation is studied carefully with significant compared with intensive ultraviolet absorbability and stronger antibacterial, the new packaging material of oxidation resistance.
Gelatin is the Partial digestion product of collagen in the connective tissues such as animal skin, bone, sarolemma, flesh evil spirit.Due in gelatin
Make it that there is stronger absorbability, therefore the albumen prepared by raw material of gelatin to ultraviolet containing a large amount of aromatic amino acids
Material can effectively prevent food corrupt because of caused by Ultraviolet Oxidation.But, gelatin is as a kind of protein easily by micro- life
Thing pollutes, in addition the water preventing ability and bad mechanical strength of gelatin based material, it is impossible to meet the requirement of market application.It therefore, it can lead to
Crossing addition antiseptic, antioxidant and cross-linking modified method strengthens the physicochemical property of gelatin materials.Curcumin (Curcumin)
It is crocus crystallization or powder that zingiberaceous plant turmeric, curcuma zedoary, the root tuber of root tuber of aromatic turmeric or rhizome Hydrolysis kinetics are obtained.Curcumin has
The effects such as anti-inflammatory, antibacterial, anti-oxidant, anti-cancer, anticancer, antiatherosclerosis, reducing blood lipid.Because curcumin molecule two ends have
Two hydroxyls, it can occur the conjugation of electron cloud deviation in the basic conditions, and then promote the color of curcumin by xanthochromia
It is red.Therefore, curcumin is compound in the gelatin-based albumen that can be prepared in gelatin substrate with excellent antibacterial and antioxygenic property
Material, at the same time the gelatin-based protein material is also with environmental pH response.Based on this, curcumin is incorporated into by the present invention
In gelatin membrane material, the antibacterial and oxidation resistant function of gelatin membrane material are realized.In addition, the raw material that the present invention is selected are can
The material of food and degraded by environment, meets the theory of Green Chemistry.
The content of the invention
Traditional is that synthesis high molecule plastic prepared by raw material can offer convenience to our life based on oil, still
It can not environmental degradability cause serious white pollution.The energy crisis being on the rise in face of the whole world and environmental pollution, grind
Study carefully and develop the biological plastics of new degraded by environment and have great importance.The present invention is using gelatin as raw material, by adding day
Prepared by right active material curcumin and cross-linking modified method have stronger antibacterial, oxidation resistance, degraded by environment and high machine
The edibility synthesized thin film of tool intensity, its specific preparation method is as follows：
(1) it is (0.5 ~ 1) curcumin to be dissolved in into ethanol with water volume ratio:In 1 ethanol-water solution, preparing mass concentration is
0.04 ~ 1% curcumin solution, then by its with mass concentration for 1 ~ 10% the solubilizer aqueous solution 25 ~ 60oUnder the conditions of C altogether
Mix and stir 10 ~ 20min, afterwards ultrasonically treated 5 ~ 20min, obtain the curcumin solution of solubilization processing；
(2) aqueous gelatin solution that mass concentration is 5 ~ 15% is prepared, the plasticizer for accounting for gelatin dry weight 10 ~ 20%, room temperature is then added
20 ~ 30min of lower stirring, the curcumin solution of itself and solubilization processing is blended in equal volume afterwards, and 20 ~ 30min is stirred at room temperature, is adjusted
Section mixed liquor pH value be 7 ~ 11 after add cross-linking agent solution, at room temperature continue stir 10 ~ 30min, be finally injected into mould
In 25 ~ 40oIt is to prepare the oxidation resistant edibility synthesized thin film of antibacterial that 24 ~ 48h is dried under the conditions of C；
The solubilizer is starch, oxidized starch, cyclodextrin, methyl-cyclodextrin, carboxymethyl-cyclodextrin and hydroxypropyl-cyclodextrin
In any one or a few mixture；
The plasticizer is any one or a few mixture in D-sorbite, mannitol, maltitol and glycerine；
The crosslinking agent is Tea Polyphenols, tannic acid, OPC, Geniposide, dialdehyde xanthans, dialdehyde carboxymethyl cellulose, double
Starch aldehyde, dialdehyde sodium alginate, dialdehyde synanthrin, any one or a few mixing of dialdehyde konjaku glucomannan and dialdehyde Weilan gum
Thing, its addition is the 5 ~ 20% of gelatin dry weight.
It is of the invention compared with existing gelatin membrane material, have the following advantages that：
(1) by will be homogeneously introduced to after curcumin solubilising in gelatin substrate, the stability of curcumin can not only be strengthened, and
And gelatin materials can be made to there is good antibiotic property and compared with strong anti-oxidation performance.
(2) synthesized thin film prepared by the present invention has quick environment pH value response, its energy in different pH environments
It is enough to show different colors in time.
(3) the characteristics of synthesized thin film prepared by the present invention also has edibility and degraded by environment, meets Green Chemistry
Idea of development, its medicine and food packaging applications there is market potential application value.
