Problems solved by technology

Studies have found that chitosan film does have a certain fresh-keeping effect, but it still does not achieve the best effect. Therefore, it is very necessary to add some substances to chitosan to enhance its antibacterial and fresh-keeping effects.
However, there is no relevant report on the preparation of microcapsule edible films by using cinnamon essential oil.

Embodiment 1

[0029] Dissolve 0.6g of chitosan with a mass concentration of 7g / L in 40ml of 1% acetic acid solution by volume, stir for 1h and filter with a pore size filter with a pore size of 1 μm, and leave the mixed solution for 12h. 1mol L -1 Na 2 CO 3 The solution was added to the above-mentioned chitosan mixed solution, the pH of the solution was adjusted to 5.0, and then 0.3 g of polyoxyethylene sorbitan monooleate was added, and a uniform mixture was obtained after stirring at 50° C. for 30 min. Add 0.03 g of cinnamon essential oil to the mixture, and stir for 1 h at room temperature to obtain the final oil-in-water emulsion. 20 ml of prepared sodium tripolyphosphate (TPP) with a mass concentration of 1.5 g / L was dropped dropwise into the obtained oil-in-water emulsion, stirred for 30 min, and then refrigerated and centrifuged to obtain chitosan-cinnamon essential oil nanoparticles. The collected chitosan-cinnamon essential oil nanoparticles were washed 3 times with ultrapure wa...

Embodiment 2

[0032] 0.28g of chitosan with a mass concentration of 7g / L was dissolved in 40ml of 1% acetic acid solution by volume, stirred for 1h and then filtered with a pore size filter of 1 μm, and the mixed solution was allowed to stand for 12h. 1mol L -1 Na 2 CO 3Add the solution to the chitosan solution prepared above, adjust the pH of the solution to 6.0, then add 0.3 g of polyoxyethylene sorbitan monooleate, and stir at 50° C. for 30 minutes to obtain a uniform mixture. Add 0.03 g of cinnamon essential oil to the mixture, and stir for 1 h at room temperature to obtain the final oil-in-water emulsion. 20 ml of prepared sodium tripolyphosphate (TPP) with a mass concentration of 1.5 g / L was dropped dropwise into the obtained oil-in-water emulsion, stirred for 30 min, and then refrigerated and centrifuged to obtain chitosan-cinnamon essential oil nanoparticles. The collected chitosan-cinnamon essential oil nanoparticles were washed 3 times with ultrapure water, then oscillated on a...

Embodiment 3

[0035] 0.28g of chitosan with a mass concentration of 7g / L was dissolved in 40ml of 1% acetic acid solution by volume, stirred for 1h and then filtered with a pore size filter of 1 μm, and the mixed solution was allowed to stand for 12h. 1mol L -1 Na 2 CO 3 Add the solution to the chitosan solution prepared above, adjust the pH of the solution to 6.2, then add 0.3 g of polyoxyethylene sorbitan monooleate, and stir at 50° C. for 30 minutes to obtain a uniform mixture. Add 0.07 g of cinnamon essential oil to the mixture, and stir for 1 h at room temperature to obtain the final oil-in-water emulsion. 20 ml of prepared sodium tripolyphosphate (TPP) with a mass concentration of 1.5 g / L was dropped dropwise into the obtained oil-in-water emulsion, stirred for 30 min, and then refrigerated and centrifuged to obtain chitosan-cinnamon essential oil nanoparticles.

Abstract

The present invention discloses a preparation technology of essential oil microcapsule edible film. The technology firstly uses chitosan as a wall material and cinnamon essential oil as a core material, an ion gel method is used to prepare chitosan-cinnamon essential oil microcapsules, then the chitosan is used as a film-forming base material, the chitosan-cinnamon essential oil microcapsules aremixed with the chitosan base material, and finally the film is formed through drying by using a tape casting method. The microcapsules of the chitosan-cinnamon essential oil microcapsule edible film prepared by using processing conditions present a uniform spherical distribution, the cinnamon essential oil is good in embedding effects, bioactive components of the cinnamon essential oil can be effectively protected, thereby volatilization of the essential oil is delayed, and the prepared essential oil microcapsule edible film is safe, non-toxic and harmless, can inhibit growth of microorganismsin packaging fruits and vegetables, thereby prolongs a shelf life of the fruits and vegetables, and also has relatively important practical research significance in other food packages.

Description

technical field [0001] The invention relates to a preparation method of a packaging material, in particular to a preparation process of an edible film of essential oil microcapsules. technical background [0002] Microcapsule technology is a technology that uses film-forming materials to embed solids, liquids or gases into clathrates with functional core-shell structures. The prepared clathrate is called microcapsule, and the particle size of the capsule is usually several microns to thousands of microns. Among them, the inner wrapped substance is called the core material, also called the guest molecule, and the outer coating material is called the wall material. , also known as the main molecule, the wall material is generally a natural or synthetic polymer material, and the core material can be liquid, solid, or gas, or a mixture of one or more substances. As an emerging technology, microcapsule technology has been widely used in food, chemical industry, agriculture and o...
