Abstract
The invention relates to a method for preparing essential oil microcapsules. According to the method, the essential oil microcapsules are prepared by taking sodium alginate as a capsule material, a syringe as a piercing device, taking a CaCl2 solution as a curing solution, using Tween-80 as an emulsifier and using silicon dioxide as a drying agent. The essential oil microcapsules prepared by the method provided by the invention have the advantages of uniform particles, good flowability and stable storage, and can control slow release.
Description
Technical field
The invention belongs to technical field of food science, relate to a kind of preparation method of essence microcapsule; The inventive method utilizes orifice method to be prepared essence microcapsule, can make essence product slowly discharge with temperature control in use.
Background technology
Microcapsules are a kind of taking polymer as wall shell, by solid, liquid or gaseous matter embedding, seal up for safekeeping at interior vesica.The film that the wall material of microcapsules forms can separate internal and external environment, can increase widely core to external world environment as the stability of light, heat, oxygen, pH etc., extend the release time of core, increase the validity of core.In recent years, the fields such as medicine, food, printing and dyeing have been widely used in.
Common essential oil is mostly made up of materials such as alcohol, aldehyde, acid and esters, these materials all have lower boiling point, and many materials all contain unsaturated bond, therefore they be easy to volatilization, occur oxidative degradation or with other material generation chemical reactions, cause the decline of quality.Conventional microcapsule method comprises following several: that spraying is dry, spraying is congealed, sprayed is cooling, freeze drying, complex coacervation and molecule embedding.Above-mentioned microcapsule method differs from one another, and is wherein most widely used in industry with spray drying process.And say in some sense, spray drying process is unsuccessful for the embedding of very volatile composition or high-thermosensitive composition, this is its weakness that is difficult to overcome.
Summary of the invention
The present invention is exactly for the problems referred to above, and a kind of preparation method of efficient, a kind of essential oil microcapsules that storage-stable is good is provided.The essential oil microcapsules that the present invention utilizes the orifice devices such as thin mouth dropper, syringe to obtain, uniform particles, good fluidity, storage-stable, can control slow release.
For realizing above-mentioned purpose of the present invention, the present invention adopts following technical scheme:
A preparation method for essential oil microcapsules, it is capsule material that the method is selected sodium alginate, syringe is orifice device, CaCl
2solution is consolidation liquid, and Tween-80 is emulsifying agent, and silica is that drier makes.
Particularly, the preparation method of these essential oil microcapsules, comprises the steps:
(1) take the sodium alginate of certain mass, be made into the aqueous solution of mass concentration 1%, press core wall mass ratio for (1-2): (1-3) add essential oil, add again the emulsifier solution of the mass concentration 0.4% of sodium alginate and essential oil mixed solution quality 2%, carry out emulsifying, time 10min;
(2) take the CaC1 of certain mass
2, be made into the sodified water solution of mass concentration 2%, after stirring, gained sodified water solution is heated to 40 DEG C, and regulate pH value between 4-5, insulation slowly stirring 1h;
(3) at the mixed liquor of syringe in-built in steps (1) gained, push the mixed liquor in syringe, mixed liquor flows out through syringe needle, falls into and fills CaC1
2in the sodified water solution tank of solution, be solidified into micro gel bead, centrifugal, remove supernatant and obtain solid micro gel bead, through distilled water washing, process finally by vacuum drying chamber is dry, obtain essential oil microcapsule product.
Preferably, described syringe needle aperture is 0.45mm.
Preferably, CaC1 in described step (3)
2the speed of agitator of solution is 800r/min.
Preferably, in described step (3), in syringe, the extrusion speed of mixed liquor is 2ml/min.
Preferably, the height of described syringe needle and sodified water solution tank is 10cm.
The beneficial effect that the present invention has:
The essential oil microcapsules that the present invention makes, uniform particles, good fluidity, storage-stable, can control slow release.
Brief description of the drawings
Fig. 1 is the schematic diagram of preparing of essential oil microcapsules.
Detailed description of the invention
The present invention will be further described by the following examples, but do not limit protection scope of the present invention.
