Abstract

The invention discloses a coixseed bran oil microcapsule and a preparation method thereof. The microcapsule is formed by embedding coixseed bran oil with wall materials accounting for, by weight 70%-75% of the coixseed bran oil microcapsule; the wall materials are prepared from, by weight, 40%-45% of Arabic gum and 50%-55% of maltodextrin. The preparation method includes the steps of preparation of wall material solutions, preparation of wall-material primary emulsions, preparation of microcapsule emulsions, spray drying and the like. Under the condition that the emulsions and organic solvents are not added, emulsibility of the Arabic gum is fully utilized, and adding order of the wall materials and core materials is changed; the microcapsule is prepared with the spray drying method, so that the obtained microcapsule is high in stability and embedding rate.

Description

A kind of Semen Coicis rice oil microcapsule and preparation method thereof
Technical field
The present invention relates to a kind of Semen Coicis rice oil microcapsule and preparation method thereof, belong to the microcapsule system in foods processing technique Standby field.
Background technology
Semen Coicis bran is the exterior materials that Semen Coicis removes when being processed into polished rice, i.e. the seed coat of Semen Coicis accounts for the total matter of whole Semen Coicis The 6%-10% of amount, oil content is 20%~25%, more high than the oil content of Semen Coicis, but is taken as honest and clean all the time The animal feed of valency and be not fully utilized, not only cause the significant wastage of Semen Coicis bran resource, also have impact on agricultural and sideline product The deep processing and utilization of product.The most less to the research of Semen Coicis bran, existing research shows: rich in multiple unsaturation in Semen Coicis rice oil Fatty acid and bioactive ingredients, the several functions active component such as including plant sterol, alkanol, oleoyl, lactams and flavone, tool There are the effects such as anticancer, antitumor, antiinflammatory, antioxidation and blood sugar lowering.
Microcapsule technology is a kind of embedding techniques, scattered solid, liquid or gas entrapment will form the technology of microgranule; It is intended to protect sensitive materials, improves materiel machining characteristic and control its release during storage and use.By Semen Coicis After rice oil is prepared as microcapsule powder, under the protection of outer layer dense film, decrease external environment (such as O2, pH, moisture, temperature Deng) destruction to Semen Coicis rice oil, particularly Oxidative demage, substantially increase the storage-stable of Semen Coicis rice oil.Additionally, Semen Coicis bran Become solid-state by liquid after oil microcapsule, it is simple to process, transport and preserve, and product good water solubility, weighing are conveniently, widen The range of application of Semen Coicis rice oil.
In existing technology, to the research of grease microcapsule the most all uses interpolation organic solvent or the method for emulsifying agent Process oil phase to be allowed to merge with aqueous phase, but the active substance in the fragile bad oil of organic solvent and flavor component, and current research table Bright, the use of emulsifying agent can change the intestinal microbial population of rat thus cause the generation of Obesity of Rats disease.There is presently no for The related art of the comparative maturity of Semen Coicis rice oil microcapsule.
Summary of the invention
It is an object of the invention to: under conditions of without emulsifying agent, it is provided that a kind of Semen Coicis rice oil microcapsule and preparation thereof Method, solves Semen Coicis rice oil oxidative rancidity problem in production, storing and intermediate links, improves the stability of product, widen Its range of application.
The present invention is achieved through the following technical solutions this purpose:
First, the present invention proposes a kind of Semen Coicis rice oil microcapsule, its micro-glue made with wall material embedding Semen Coicis rice oil Capsule, wherein, wall material amount accounts for the 70%~75% of this Semen Coicis rice oil microcapsule quality;Wall material is by arabic gum and maltodextrin system Becoming, in wall material raw material, by mass percentage, arabic gum accounts for 40%~45%, and maltodextrin accounts for 50%~55%.
The preparation method of this Semen Coicis rice oil microcapsule comprises the steps:
(1) prepared by wall material solution: added by arabic gum in the hot water of 60~70 DEG C, and stirring and dissolving prepares wall material Solution;
(2) prepared by wall material just emulsion: being added in the wall material solution that step (1) obtains by Semen Coicis rice oil, temperature is maintained at 40~60 DEG C, stirring and emulsifying 10~15 minutes, then add maltodextrin as wall material in the ratio of arabic gum and maltodextrin Filler, stirring and emulsifying 15~20 minutes, prepare wall-forming material just emulsion;It is initially charged after Semen Coicis rice oil forms first emulsion and adds again Enter maltodextrin, it is therefore an objective to make full use of the emulsibility of arabic gum, strengthen the stability of microcapsule, avoid additionally adding simultaneously Emulsifying agent.
(3) preparation of microcapsule emulsion: the wall material that step (2) is prepared just emulsion high speed disperser with The VELOCITY SHEAR 8 of 20000r/min~10 minutes, stop to emulsion and be cooled to room temperature, then with high speed disperser with 10000r/ The VELOCITY SHEAR of min 10 minutes, then under the pressure of 30~40Mpa, homogenizing prepares microcapsule emulsion for twice;
(4) it is spray-dried: the microcapsule emulsion that step (3) prepares is spray-dried;The air intake of spray dryer Mouthful temperature controls at 180 DEG C, and air outlet temperature is 80~90 DEG C, and sample introduction flow is 4ml/min, stir under the conditions of normal pressure and temperature into Sample, prepares Semen Coicis rice oil microcapsule.
Wherein, in step (1), the consumption of water is arabic gum in this microcapsule, maltodextrin and three kinds of raw materials of Semen Coicis rice oil 1.8~2.3 times of gross weight.
Beneficial effects of the present invention: (1) present invention prepares Semen Coicis rice oil microcapsule with Semen Coicis rice oil for raw material, " change give up into Precious ", resource sufficient, solve intensive processing and the storing of Semen Coicis rice oil, the problem of oxidation of becoming sour of Semen Coicis product, widen simultaneously The range of application of Semen Coicis rice oil.(2) present invention is under conditions of without emulsifying agent and organic solvent, makes full use of arabic gum Emulsibility, change wall material and the order of addition of core, use spray drying method to prepare microcapsule, its microcapsule prepared is stable Property is strong, embedding rate is high.
