Abstract
The invention discloses a starch-based film (as shown in attached graphs) with antibacterial microcapsules and a method for manufacturing the starch-based film. Starch is used as a film forming base material, the antibacterial microcapsules and auxiliaries such as gelatin, glycerin and CaCl<2> are added into the starch, and the starch-based film is manufactured in molds by the aid of a tape casting process. The method includes firstly, manufacturing the microcapsules from clove essential oil and beta-cyclodextrin by the aid of a molecular inclusion process, and reserving the microcapsules; secondly, stirring the starch at certain temperatures to form paste, heating and dissolving a certain quantity of the gelatin, and weighing certain quantities of the glycerin and the CaCl<2> for standby application; thirdly, proportionally adding the gelatin, the microcapsules, the glycerin, the CaCl<2> and the like into the liquor of the starch after the paste of the starch is formed, and stirring the gelatin, the microcapsules, the glycerin, the CaCl<2> and the like in the liquor of the starch for 20min to obtain mixed liquor; fourthly, cooling the mixed liquor until the temperature of the mixed liquor is equal to the room temperature, pouring the mixed liquor into the self-made molds, carrying out tape casting on the mixed liquor, drying the mixed liquor in drying tanks until the weight of the mixed liquor is constant; fifthly, tearing the film and testing the performance of the film. The starch-based film with the antibacterial microcapsules and the method have the advantages that the starch-based film is made of extensive raw material sources and is safe, hygienic, environmental friendly and degradable, and excellent inhibition effects can be realized for microorganisms in foods; the starch-based film can be used for antibacterial packages for the fresh foods and has a broad development prospect.
Description
Technical field
The present invention relates to a kind of starch base antibacterial film containing microcapsule and preparation method thereof.
Background technology
Starch is considered to one of biological degradation packaging material most with prospects.The starch film that starch is made after gelatinization, retrogradation, drying has that tensile property is good, transparency advantages of higher, but still there is germ resistance bad shortcoming during for packing.Multinomial research shows by the mode of compound, to improve the anti-microbial property of starch film.Clove oil has stronger fungistatic effect, but is insoluble in water, less stable, and oxidizable, volatilization, limits its antibacterial effect to a certain extent.Microcapsulary is that a kind of film forming material is solid or the coated technology making it to be formed fine particle of liquid.Clove oil can be wrapped in wall material by microcapsulary, the germ resistance of clove oil can be kept, its validity period can be extended again.
Preparation method about antibacterial starch-based film has some bibliographical informations like this:
Kuorwel etc. are studied the anti-microbial activity (AM) of starch-based film to streptococcus aureus that is external or that be seeded in cheddar cheese-surface scribbling phantol, isothymol or thymol.Research shows: within the scope of finite concentration, and the susceptibility order of streptococcus aureus to antiseptic-germicide is: thymol > isothymol > phantol.
China of State of Zhao waits Bulbus Allii quintessence oil to add in tapioca (flour) and has made antibacterial starch edible film, and when result shows that adding Bulbus Allii quintessence oil is 1.5% of tapioca (flour) quality, antibacterial starch edible film has best antibacterial effect to intestinal bacteria and streptococcus aureus.
Cinnamon essential oil, chitosan and N,O-Diacetylmuramidase add in W-Gum film by Zhao Dan, have made antibacterial starch film, and have studied it to intestinal bacteria and streptococcus aureus inhibition.Result shows, the W-Gum film adding chitosan has best inhibition to intestinal bacteria, and the W-Gum film adding cinnamon essential oil has best inhibition to streptococcus aureus.
In sum, current Chinese scholars mainly concentrates on research prepared by antibacterial starch-based film and add natural or artificial antiseptic-germicide in starch film.Plants essential oil is a kind of natural antibacterial agent of good performance, but its main complex method adds in film base material, or is coated on the surface of film.Because essential oil has volatility, this limits its antibacterial effect to a certain extent.Clove oil is wrapped in wall material, make the microcapsule with germ resistance, and antibacterial microcapsule is added in starch film liquid, starch-based film can be made to obtain good germ resistance, extend its antibacterial validity period, be an important development direction prepared by antibacterial starch-based film simultaneously.
Summary of the invention
Patent of the present invention mainly for be Problems existing in existing domestic and international antibacterial starch-based film preparation, provide a kind of good anti-bacterial effect, starch-based film containing antibacterial microcapsule that validity period is long and preparation method thereof.
The present invention for achieving the above object, is realized by technical scheme below.
The mass percent prepared containing the starch-based film of antibacterial microcapsule of the present invention:
According to the per-cent that technical scheme provides, the present invention is as follows containing the starch-based film preparation method of antibacterial microcapsule:
1) 6g beta-cyclodextrin 36ml distilled water is dissolved, for subsequent use.
2) 1g clove oil is dissolved in the ethanol that 20ml volume fraction is 60%, and dropwise adds in the aqueous solution of beta-cyclodextrin.
3) stir at 60 DEG C of temperature after 2.5 hours and take out, be chilled to until solution the refrigerator being placed on 4 DEG C after room temperature and leave standstill 24 hours.
4) by leave standstill after solution suction filtration, filter residue dehydrated alcohol and distilled water wash respectively.
5) dry at 50 DEG C of temperature, make clove oil/beta-cyclodextrin antibacterial microcapsule, for subsequent use.
6) the starch wiring solution-forming of film gross weight 44-50% is taken, gelatinization 20min at 80 DEG C.
7) take the gelatin of film gross weight 9-17%, continue at 60 c to stir 20min.
8) glycerine of 26% is added again, 9-17% antibacterial microcapsule and 4-8%CaCl
2stirring reaction 20min makes film forming liquid.
9) film forming liquid is carried out froth breaking, cooling.Then pour in molding jig, put into 50 DEG C of thermostatic drying chambers, after being dried to constant weight, take off film.
The present invention is about the preparation method of the starch-based film containing antibacterial microcapsule, this preparation method utilizes microcapsulary to be wrapped in beta-cyclodextrin by clove oil, and add in starch base fluid, by solution casting method after curtain coating in molding jig, after freeze-day with constant temperature certain hour, namely break the mold can be made into the starch-based film containing antibacterial microcapsule.Feature of the present invention:
1) the technology of the present invention is using starch etc. as one-tenth film base material, has wide material sources, with low cost, the advantages such as degradable green;
2) clove oil that the technology of the present invention adopts is the excellent natural antibacterial agent of a kind of antibacterial effect, and harmless to human non-toxic, safety and sanitation;
3) use microcapsulary to be wrapped in beta-cyclodextrin by clove oil, overcome the volatile shortcoming of essential oil, extend antibacterial ageing;
4) starch-based film containing antibacterial microcapsule that prepared by present invention process has good antimicrobial property and sanitation performance, can be used for the packaging of fresh product, has vast potential for future development.
