Abstract
The present invention relates to a pollen sac deaeration embedding method which uses a pollen sac as a wall material. Firstly, a pollen slag is pretreated, and then a sac core material to be embedded is filled in the pollen sac by passing through the germ pore of the pollen under the action of negative pressure; subsequently, the germ pore is sealed by a sealing agent to form a microcapsule of 10 to 200 mu m, wherein the sealing agent is a natural polymer material, such as chitosan, or a resinous material. According to the character of the sac core material, the pollen sac deaeration embedding method can be concretely divided into three methods for preparing microcapsules. The present invention has the advantages that a wall material combined by pollen slags, chitosan or resin is embedded with fat-soluble nutritive substances and water-soluble nutritive substances to be made into a microcapsule, and the microcapsule masks the unpleasant smell of the embedded substances and can prevent the oxygenizing deterioration of the embedded substances, so that the physical property of the embedded substances is stabilized, the embedded substances have higher biological activity and longer shelf life, and the shelf life of a commodity is prolonged.
Description
Technical field
The present invention relates to a kind of preparation method of microcapsules, mainly is a kind of pollen sac deaeration embedding method.
Background technology
Microcapsules technology is a kind of technology that solid or liquid coating is made the formation fine particle with filmogen.The fine particle that obtains is microcapsules, and general appearance is spherical, and size is at the 5-500 mu m range.Generally, capsule is exactly " pocket ", and microcapsules are exactly " small pocket ".The material that wraps in microcapsules inside is called the capsule heart.The capsule heart can be a solid, also can be liquid or gas.The coating film that the microcapsules outside is formed by filmogen is called the wall material.The wall material is normally formed by macromolecular material natural or that synthesize, also may be inorganic compound.When the advantage of microcapsules technology was to form microcapsules, the capsule heart was isolated with external environment by coating, and its character can be retained with having no effect, and under proper condition, the capsule heart can be discharged again when the capsule material is destroyed.This brings many facilities to use.Behind liquid formation microcapsules, become pressed powder, this all brings great convenience for its use, transportation, storage.
The material that can use of preparation microcapsules is a lot, as natural macromolecular material or organic synthesis material.The maximum characteristics of these materials are to have certain film forming, and more stable at normal temperatures.Commonly used have a starch based: maltodextrin, cyclodextrine, converted starch etc.; Water-soluble glue class: gelatin, Arabic gum, agar, algin etc.; Synthesized polymer material: polyamide, polyisoprene, polyethylene, epoxy resin etc.
The determining and should consider of microcapsule preparation method in actual production according to combined factors such as physicochemical property, product quality requirement and the equipment of encapsulated heart material, costs, the purpose that reaches not only economy but also meet the demands.The cyst material of selecting for use must meet the national health requirement, does not react with the core material that is wrapped.The method that the feed addictive microencapsulation adopts is mainly spray drying process, complex coacervation, beta-schardinger dextrin-investment.
Summary of the invention
Technical problem to be solved by this invention provides a kind of biologically active that stability is high, maintenance is higher that can make core material, and the lower pollen sac deaeration embedding method of financial cost.
The technical solution adopted for the present invention to solve the technical problems.This pollen sac deaeration embedding method adopts pollen bag as the wall material, and after described pollen bag was meant and produces pollen extract, discarded pollen slag was mainly the pollen shell of hollow, i.e. the pollen bag that germinal aperature is open and content has disengaged.The pollen slag is carried out preliminary treatment, with the pollen slag behind the extraction pollen extract, wash with water again and remove residual sugar, anhydrate so that 3000rpm is centrifugal with centrifuge, dry or put baking oven low temperature with daylight, temperature is controlled at below 70 ℃, can keep active material such as flavonoids useful in the pollen slag to biology, oven dry will prevent to go mouldy and damage by worms after doing, and can carry out the 5-8kGy radiation treatment.Core material with want embedding is entered in the pollen bag by the germinal aperature of pollen under suction function then, and core material is the solution or the composite bacteria liquid of oily liquids or soluble solids; After then adopting sealing compound that germinal aperature is sealed, finally make microcapsules.
The technical solution adopted for the present invention to solve the technical problems can also be further perfect.Described sealing compound is natural macromolecular material such as shitosan, its deacetylation＞90%, and ash content＜8%, mercury＜0.3mg/kg is dissolved in shitosan in 2% the acetum, is made into the chitosan-acetic acid solution of 1-1.5%.The deacetylation of shitosan is big more, is soluble in diluted acid more, and the consumption of shitosan liquid is the 10-15% of the capsule heart and wall material total amount, and the embedding effect is better.Described sealing compound also can adopt resinous material, and as polymethacrylates, in 95% ethanol, state reaches capacity with resin dissolves.The use amount of resin ethanolic solution is the 10-15% of the capsule heart and wall material total amount during embedding.
1), core material is oily liquids (fish oil), adds vitamin E or other antioxidants of fish oil amount 1-3% in refining fish oil, fully mixing proterties according to core material can be specially following three kinds of microcapsule preparation methods:; The fish oil capsule heart is added in the pollen slag that the degassing is handled, fish oil is entered in the pollen bag through pollen germination pore under suction function, after the inflation, again with the fish oil outside the beta-schardinger dextrin-absorption pollen bag of 5-10%, close the germinal aperature of pollen bag at last with the shitosan fluid-tight, after the low temperature drying, promptly make the fish oil powdery product of microencapsulation.2), core material is soluble solids solution (complex enzyme for feed), and complex enzyme is dissolved in water, reaches saturation state; The complex enzyme saturated solution is added in the pollen slag that the degassing is handled, the enzyme saturated solution is entered in the pollen bag through pollen germination pore under suction function, after the inflation, dry under low temperature (under 40 ℃) or freezing conditions; Close the germinal aperature of pollen bag again with the alcohol resin fluid-tight, after the low temperature drying, promptly make the complex enzyme powdery product of microencapsulation.3), core material is compound lactobacillus bacterium liquid, will make 10 by cultivation and fermentation
9-10
10The bacterium liquid of individual/ml adds in the pollen slag that the degassing is handled, and bacterium liquid is entered in the pollen bag through pollen germination pore under suction function, after the inflation, and freeze drying; Promptly make the compound lactobacillus powdery product of microencapsulation.
The effect that the present invention is useful is: carry out the fat-soluble and water-soluble nutrient substance of embedding by the wall material of pollen slag, shitosan or resin combination and make micro-capsule, this kind micro-capsule has been covered by the unhappy smell of embedding substance, can prevent by the oxidation deterioration of embedding substance, make by the embedding substance stable in properties and have higher biologically active, have the long shelf-life, prolonged the shelf life of commodity.
