The vitamin content of vitamin slow-release microcapsule powder prepared by the present invention can reach more than 70%, and the present invention has the characteristics of high content, favorable fluidity and extrusion resistance, can be further made into tablets and has a favorable slow-release effect.
Description
Technical field
The invention relates to a kind of preparation method of high-content oil-soluble liquid vitamins slow-releasing microcapsule powder.The oil soluble liquid vitamins comprises the succinate of the acetate of vitamin E or vitamin A or vitamin E or A or vitamin E or dissolves in the oil-soluble solid vitamin of oiliness material such as the mixture of vitamin D or vitamin K or two or more fat soluble vitamin etc., belongs to biomedical sector.
Background technology
Oil soluble liquid vitamins product such as vitamin E (being called for short VE), since finding, it enlarges day by day at medical industry and Application in Food Industry.Nineteen fifty-nine, U.S. food and the official confirmation VE of nutrition committee are the essential compositions of human nutrition.Because VE has many physiological functions,, FAO (Food and Agriculture Organization of the United Nation) and world health replenish an amount of VE to satisfy human body requirements every day so knitting suggestion.The major function of VE is: (1) antisterility function can be used for treating habituation or threatened abortion; (2) antitumaous effect; (3) can be used for treating cardiovascular disease such as coronary heart disease, myocardial infarction, arteriosclerosis; (4) have anti-oxidation function, and can improve the utilization rate of oxygen in the blood, thereby improve muscle endurance, can be used for treatment of diseases such as progressive muscular dystrophy; (5) have anti-aging effects, can strengthen the human body immune function, the old people takes VE for a long time, can improve its general situation, comprises the functional status of lymphsystem, skeletal muscle and cardiovascular system.In order to make full use of these functions of VE, various forms of VE new product technologies of preparing continue to bring out, thereby it is more widely used at aspects such as medicines and health protection, food industry, cosmetics industry, animal feed and sensitive materials.But along with the increase of oral VE number, the especially increase of the oral quantity of old people, present dosage form just seems and is far from suitable.Because peroral dosage form still based on capsule, is the assurance high-load, efficient, capsule is done bigger and bigger.But after this capsule enters human body, a large amount of contents still exist with the grease form, thereby, there is major defect aspect flowability, the absorption, show as low bioavailability, therefore study VE new product and just seem extremely important with high bioactivity and high-absorbility.
The main component of VE is an alpha-tocopherol, but normally oil-soluble liquid such as tocopherol and ester type compound thereof such as tocopherol acetate, tocopherol succinate etc., and water insoluble, its bioavailability is low, and absorption difference uses and transports also extremely inconvenient.For improving bioavailability and absorption efficiency, to be convenient to again take, pack, transport and sell, oneself becomes the developing direction of this product exploitation VE powder or VE sustained-release micro-spheres powder.At present, the domestic common VE powder (content: 50%), be mainly used in animal feed additive of only producing.And abroad, pharmaceutical grade high-load VE sustained-release micro-spheres powder (content: 75%) except that as the medical product, also be widely used as nutrient additive for food and food supplement, improved the bioavailability of VE greatly, also opened up new wide market for the application of VE powder.
United States Patent (USP) (6,030,645) introduced a kind of method for preparing the oil soluble liquid microcapsule, be that oil soluble material emulsifyings such as VE are dispersed in the aqueous gelatin solution, form minuteness particle, by spray drying, emulsion is sprayed on the bed that is paved with the calcium silicates powder, form the microcapsule that the outside is surrounded by calcium silicate powder.
The high-load VE powder of preparation that United States Patent (USP) (6,020,003) is introduced is to make the capsule material with a kind of not gelatin hydrolysate, and VE emulsifying is dispersed in the aqueous gelatin solution, forms minuteness particle, makes by spray drying.
United States Patent (USP) (6,001,554) method for preparing high-load VE microcapsule of Jie Shaoing is by VE emulsifying being dispersed in the aqueous solution of cellulose ether, by changing temperature or regulating pH, make the capsule material solidify to form primary particle, the aqueous solution that adds another seed capsules material again carries out coating the second time or coating for the third time, and the particle of Xing Chenging makes microcapsule by spray drying at last.
There is following technical deficiency in above-mentioned technology: only by spray drying granulation, the difficult control of balling-up size coats also tightly inadequately, makes olefiant seepage easily, does not have slow releasing function; In addition～and the aspect, repeatedly coat and be difficult to accomplish high oil content.
Summary of the invention
The preparation method that the objective of the invention is to avoid deficiency of the prior art and a kind of high-content oil-soluble liquid vitamins slow-releasing microcapsule powder is provided.A kind of preparation method of high-content oil-soluble liquid vitamins slow-releasing microcapsule powder, its characteristics are to adopt Water-In-Oil bag oil (O
1/ W/O
2) the emulsion cladding process, the vitamin slow-releasing microcapsule powder of preparation can form nucleocapsid structure, and one or more emulsion particles are covered by in the scrotiform shell, and the microcapsule of Xing Chenging is in dispose procedure like this, can one by one elaioleucite be discharged, reach the effect of long-acting slow-release.Adopt each vitamins slow-releasing microcapsule powder vitamin content of system of the present invention can reach more than 70%, have the feature of content height, good fluidity, anti-extruding, can further make tablet, have good slow release effect.
Purpose of the present invention can reach by following measure: the plain analog derivative of the outer clad material series fiber of high-load vitamin slow-releasing microcapsule powder, or polypeptide class such as gelatin, or Biodegradable materials such as polysaccharide such as arabic gum, account for the 8-15%wt of microcapsule: comprised the succinate of the acetate of vitamin E or vitamin A or vitamin E or A or vitamin E or dissolve in the oil-soluble solid vitamin of oiliness material such as the mixture of vitamin D or vitamin K or two or more fat soluble vitamin etc. that the content of oil soluble materials such as the vitamin that is coated or its ester is more than 70% by the oil soluble liquid vitamins that coated; The center of high-load vitamin slow-releasing microcapsule is the O/w emulsion kernel, includes one or more emulsion particles: the particle diameter of high-load vitamin slow-releasing microcapsule is at 100-400um.The microcapsule clad material is cellulose derivative such as biodegradable hydroxypropyl cellulose, hydroxypropyl emthylcellulose, hydroxypropylmethyl cellulose phthalate, ethyl cellulose, methylcellulose etc. or polypeptide analog derivative such as polyamino acid, gelatin etc. or polysaccharide derivatives such as arabic gum, sodium alginate etc., biomedical material.Can be wherein a kind of, also can be two or more mixtures of material.For fat soluble vitamin is the microcapsule of capsule core material, adopts Water-In-Oil bag oil (O
