Description
Technical field
The present invention relates to Food Engineering Development field, particularly a kind of peony seed oil microcapsules and preparation method thereof.
Background technology
Peony seeds is the elite crystallization of peony plant, has natural longevity gene.The vegetable oil extracted by peony seeds, unsaturated fatty acid content reaches more than 90%, and wherein polyunsaturated fatty acid-linolenic acid content is more than 40%, is 140 times of olive oil.Peony seeds has kind containing multiple nutritional labelings useful to human body such as vitamin E, phytosterol, squalene, trace elements simultaneously, anti-oxidant, protect the liver, reducing blood lipid, hypoglycemic, sun-proof etc. in there is outstanding effect, be the pure natural plant grease of great exploitation potential for its.
On March 22nd, 2011, peony seed oil obtained new resource food approval.At present, the extraction process of peony seed oil reaches its maturity, but deep processing research is fewer, rarely has report for the scientific paper of the microcapsule embedded technology of peony seed oil and patent of invention.Patent document 1(CN104206561A, denomination of invention is " a kind of preparation technology of peony seed oil microcapsule powder ") disclose a kind of preparation method of peony seed oil microcapsules.The stabilizing agent that the method does not add salt ion one class carrys out equilibrium water solution system, causes embedding rate to reduce (embodiment 2 embedding rate 95.1%), the very fast phenomenon (test example 3) occurring oil slick in the different time of the reconstituted milk after reconstituting.In addition, spray-dired EAT (110-170 DEG C) and leaving air temp (60-90 DEG C) too high, the loss of volatile flavor substance can be caused, affect mouthfeel.Although be instant product, must heating hot water (80 DEG C of test example 2), be difficult to accomplish instant in cold warm water.Because which limit its application in food, medicine.Patent document 2(CN103948035A, denomination of invention is " peony seed oil microcapsules, its preparation method and application ") disclose two kinds of preparation methods of peony seed oil microcapsules: yeast method and complex coacervation.Wherein, yeast method needs the deactivation of yeast purifying, and complex coacervation needs solidification, and finally also want vacuum drying or freeze-drying, the operating time is long, and energy consumption is high, complex process, and industrialization difficulty controls, and efficiency is low.
In a word, above method is in peony seed oil microcapsules preparation process, and suitability for industrialized production is more difficult, and product stability is poor, affects the utilization of product in food, medicine, cosmetics, health products etc.
Summary of the invention
In order to make up above deficiency, the invention provides a kind of epigranular, restoration is good, dissolubility is good, can dissolve in cold water, solution deposit-free and floating thing, nutriment lose few peony seed oil microcapsules and preparation method thereof.
Technical scheme of the present invention is:
A kind of peony seed oil microcapsules, comprise core phase and wall material phase, according to weight parts, described core is made up of 10-60 part peony seed oil and 0.5-5 part oil soluble emulsifying agent; Described wall material is connect auxiliary agent, 20-150 part water, 1-8 part water soluble emulsifier and 0.5-5 part stabilizing agent formed by 20-75 part wall material, 5-50 part wall material.
Preferably, described oil soluble emulsifying agent is one or more in sucrose ester, fatty glyceride, phosphatide.Described fatty glyceride is generally mono fatty acid glyceride, bis-fatty acid glyceride or its mixture (aliphatic acid list double glyceride).
Preferably, described water soluble emulsifier is one or more in caseinic acid, casein sodium, Caseins, potassium salts, water-soluble plant albumen.
Preferably, described stabilizing agent is one or more in citric acid, natrium citricum, potassium citrate, sodium hydrogen phosphate, dipotassium hydrogen phosphate.
Preferably, described wall material is one or more in malt syrup (dextrin), gelatin, Arabic gum, xanthans, protein, converted starch, cellulose derivative; Described wall material connection auxiliary agent is sucrose and/or glycerine.
The preparation method of described peony seed oil microcapsules, step is as follows:
1) preparation of core phase, adds 0.5-5 part oil soluble emulsifying agent, heating for dissolving in 10-60 part peony seed oil, obtained core phase;
2) preparation of wall material phase, to join 20-75 part wall material and 5-50 part wall material connection auxiliary agent in 20-150 part water and to be heated to 50-90 DEG C, then adding 1-8 part water soluble emulsifier and 0.5-5 part stabilizing agent, obtained wall material phase;
3) described core phase mixed mutually with wall material, emulsifying homogeneous becomes particle diameter to be the emulsion of 100-2000nm;
4) by described emulsion drying-granulating, obtained peony seed oil microcapsules.
Preferably, heating for dissolving described in step 1), is heated to 30-60 DEG C.
If step 2) in do not add wall material connection auxiliary agent, during step 4) drying-granulating, wall material has easily produced porous, easily causes core to leak, therefore gained microcapsules instability.Wall material connection auxiliary agent (sucrose and or glycerine) has mobility under the hot environment of spraying-fluid bed, and its mobility impels wall material tight, even to core parcel.
Preferably, described oil soluble emulsifying agent is one or more in sucrose ester, fatty glyceride, phosphatide; Described water soluble emulsifier is one or more in caseinic acid, casein sodium, Caseins, potassium salts, water-soluble plant albumen; Described stabilizing agent is one or more in citric acid, natrium citricum, potassium citrate, sodium hydrogen phosphate, dipotassium hydrogen phosphate; Described wall material is one or more in malt syrup, gelatin, Arabic gum, xanthans, protein, converted starch, cellulose derivative; Described wall material connection auxiliary agent is sucrose and/or glycerine.
Preferably, emulsifying homogeneous described in step 3) first shears pre-emulsification in high-speed shearing machine; Then further emulsifying in high pressure homogenizer, the pressure of high pressure homogenizer is set to 20-80MPa.In step 3), after high-speed shearing machine high speed shear pre-emulsification, use pressure emulsifying homogeneous method to carry out nanometer, thus overcome the uneven shortcoming such as cause reconstituted milk floating oil, wall material protected effect bad of the particle diameter caused in prior art.
Preferably, drying-granulating described in step 4) carries out at spraying-fluid bed, and spraying-fluid bed EAT is set to 80-120 DEG C, and leaving air temp is set to 10-60 DEG C.
Beneficial effect of the present invention is:
The method that the present invention prepares peony seed oil microcapsules adopts microcapsules technology by peony seed oil microencapsulation, the method utilizes macromolecular material that is natural or synthesis that peony seed oil is rolled into microcapsules, therefrom product water dissolubility and stability better, and energy suitability for industrialized production, thus the range of application overcoming prior art existence is narrower, the problem of less stable.Comprehensive, peony seed oil microcapsules of the present invention have following advantages:
1. the present invention uses pressure emulsifying homogeneous to make emulsion particle diameter reach nanoscale, thus the product granularity obtained is even, restoration is good, dissolubility is good, can dissolve in cold water, solution deposit-free and floating thing, leave standstill after 48 hours without oil slick, can be composite arbitrarily with other emulsions, as milk, milk beverage etc.Thus widened the range of application of peony seed oil;
2. the present invention adopts low temperature drying, decreases the loss of peony seed oil volatile materials, retains fragrance and mouthfeel specific to peony seed oil;
3. this particle has certain compressibility, can make an addition in tablet, there will not be oil leakage phenomenon through tabletting machine, may be used on milk sheet, buccal tablet etc.
4. the peony seed oil microcapsules particulate obtained by the method for the invention has good mobility, therefore facilitates it and uses, transports and storage;
5. preparation method of the present invention is simple, and route is reasonable, safe and reliable, maintains the nutritional activities of peony seed oil, thus has remarkable advantage.
