Abstract
The invention relates to a fennelflower seed volatile oil microcapsule preparation method and belongs to the technical field of microcapsules. The processing steps includes that chitosan and isolated soy protein are used as wall materials; the fennelflower seed is used as core material; monostearin and sucrose ester are used as compound emulsifier; the materials are homogenized under high pressure to form lactescence, and finally, fennelflower seed volatile oil microcapsule products are prepared by freezing and drying the lactescence. The fennelflower seed volatile oil microcapsule preparation method is simple, does not need special technological equipment; the stability and solubility of products are better, and the products are easy to store and transport.
Description
Technical field
The invention belongs to microcapsule technology field, be specifically related to a kind of preparation method of Semen Nigellae microcapsule.
Background technology
Semen Nigellae volatile oil is the chemical constituent extracted in the dry mature seed of dimension medicine nigella glandulifera Freyn, is mainly m-p-Cymene, thymoquinone etc.Just find that Semen Nigellae volatile oil can expansion bronchus the sixties in last century abroad, then find that it has antitussive effect, active component thinks the thymoquinone in volatile oil.Although Semen Nigellae volatile oil has many pharmacologically actives, there is also the shortcomings such as volatile, dissolution dispersity is poor, have impact on its application.
Microcapsule technology refers to and utilizes macromolecule filming material to form after the solid of specifying and liquid embedding the embedding techniques that diameter is 1 ~ 1000 μm of particle.These solids be embedded, liquid are referred to as core, and its outer wall is called wall material.The microcapsule that core material is formed after embedding, has different new function in the past and character.The function of microcapsule mainly contains: one be prevent or slow down core material volatilization unstable, the effect of the protection core such as oxidation and corruption; Two is overcome some core material poor fluidities, not easily preserve, be inconvenient to the shortcoming of transporting; Three is bad smell or the taste of covering core material, makes core material slow releasing etc. according to certain requirement.
At present, there are no research report Semen Nigellae volatile oil being carried out to micro encapsulation.Be also main mainly with spraying dry to the micro encapsulation of other volatile oil in production, the report that freeze-drying prepares volatile oil microcapsule is also comparatively rarely seen.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of Semen Nigellae volatile oil microcapsule.
The present invention is achieved by following technical solution:
A. to be the chitosan of 2:1 ~ 3 and soybean protein isolate distilled water preparation mass percent concentration by mass ratio be 20 ~ 40% wall material solution, after ultrasonic pretreatment, for subsequent use; ;
B. be that the monoglyceride of 1:1 and the compound emulsifying agent of sucrose ester add in above-mentioned wall material solution by the Semen Nigellae volatile oil of 20 ~ 30% of coating material quality and the mass ratio of 1 ~ 2%, stand-by stir 10min under 2000 ~ 4000r/min rotating speed after;
C. above-mentioned mixed liquor is added in high pressure homogenizer, at 60 ~ 70 DEG C, homogenizing 10min under 10 ~ 20MPa, form Semen Nigellae volatile oil emulsion;
D. put into after the pre-cooling of Semen Nigellae volatile oil emulsion the preparation that freezer dryer vacuum lyophilization completes microcapsule, obtained Semen Nigellae volatile oil microcapsule.
The protein content > 90% of the soybean protein isolate described in step a.
Vacuum lyophilization condition described in steps d is :-30 ~-40 DEG C, 50 ~ 100Pa.
The invention has the advantages that: adopt freeze-drying, effectively prevent the loss of Semen Nigellae volatile oil in preparation process, and Semen Nigellae volatile oil is after the process of freeze-drying micro encapsulation, the shortcoming of self can be overcome, its stability and dissolution dispersity are all improved, and are easy to storage and transport.
Further illustrate the present invention below in conjunction with detailed description of the invention, but the scope of protection of present invention is not limited to following embodiments.
