The method can more favorable maintain the active component and the unique penetrability of the ostrich oil, has simple method, convenient operation, short production time, no residual solvent, environmental-friendly production process and industrial application prospect, more favorable prevents the oxidation and decomposition of an unsaturated fatty acid component, maintains the active component and the favorable penetration characteristics of the ostrich oil and leads the materials not to be in contact with a poisonous organic solvent in the process of extraction.
Description
Technical field
The invention belongs to the extraction and the working method of natural product, relate generally to a kind of animal oil and fat preparation method of extract, relate in particular to a kind of preparation method of ostrich oil.
Background technology
Ostrich belongs to tropical desert birds, is maximum birds.Through degenerating over the past thousands of years, ostrich has become and only can not run and can fly, but its explosive power is very strong, reaches 70 kilometers/hour 3 seconds, and speed per hour can continue for 70 kilometers to run about 40 minutes.The ostrich build of growing up is very large, raises one's head 2.5 meters, and holding capacity is strong, and regenerative power is strong, and self-healing ability is strong.Surprisingly, living in the refrigerant latitudes ostrich can keep in joint, the subzero 30 degree left and right sides ossifing flexibly and not.The scientist's of the U.S. and Iceland research confirms: the adipocyte in the middle of the osteoarthrosis can be after the ostrich bone damage self quick reparation.
At Europe And Africa, people find for a long time, and ostrich oil can be eliminated because of sacroiliitis, the caused pain of scapulohumeral periarthritis in the utmost point releive in the short period of time muscle and joint, but also the bruise that causes because of motion or slight wound inflammation are played therapeutic action.The experimental study of modern science shows that also ostrich oil has the ability of very strong infiltration skin, can ooze apace to reach bone or skin depths.
In recent years, the aquaculture development of domestic ostrich is very fast, and the amount of livestock on hand of ostrich reaches thousands of.Simultaneously, also development to some extent of the comprehensive processing technology of ostrich.Patent CN200410067086.6 has studied a kind of prepared food method of processing ostrich meat.This working method combines ostrich meat nutritive ingredient and traditional Chinese medicine knowledge, makes the color of ostrich meat all good, and mouthfeel is peculiar, meets the demand of modern nutritive, nourishing and health-care.Patent CN 02123771.9 proposes a kind of Ostrica bone medicinal liquor and preparation method thereof, has developed the pharmaceutical use of Ostrica bone.Patent CN 200610105029.1 utilizes the ostrich treated oil to make the novel sunscreen cosmetic cream of preserving moisture.Through scientific composition, product innovation has significant desalination freckle, gets rid of pigmentation, keeps skin life, prevents the advantage that water molecules runs off.Patent CN200610042782.0 then utilizes ostrich oil to develop the Tibetan medicine paste of a kind of effective treatment skin wound and burn and scald.Obviously, for the great interest of peculiar effect of ostrich oil and product innovation research having caused all circles with show great attention to, but seldom about the extraction of ostrich oil and Study on Processing Technology.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of ostrich oil, realize through following steps:
(1) minced meat shape ostrich fat is encased in the barrel of supercritical extraction unit configuration, puts into extraction kettle to barrel again, open CO
2Steel cylinder, through condensing surface with fresh CO
2Liquefaction, liquid CO
2Become supercutical fluid through HPP, mixing tank and interchanger, setting the extraction kettle pressure range is 15～40MPa, and the temperature of extraction kettle is 35～60 ℃;
(2) supercritical solution after the extraction gets into separator 1 and separator 2 successively, and the pressure range of separator is 4～9MPa, and TR is 40～60 ℃, separates out the grease-like extract through the reduction pressure of separator, CO in the supercritical extraction process
2Recycling, is the extraction kettle of 1L with respect to volume, CO
2Flow range is 10～30L/h, and extract is emitted from the bottom of separator aperiodically, is collected in the container, and the supercritical fluid extraction product is a Liquid Paraffin smectic solid.
In the supercritical extraction process, the extraction kettle pressure range is 15～40MPa, serves as better with 20～25MPa wherein; Extraction temperature is 35～60 ℃, serves as better with 45～55 ℃ wherein.
The pressure of separator 1 is 7～9MPa, and temperature is 50～60 ℃; The pressure of separator 2 is 4～6MPa, and temperature is 40～55 ℃.
Ability according to supercritical extraction equipment is set appropriate C O
2Flow.With respect to volume is the extraction kettle of 1L, CO
2Flow range is 5～30L/h, serves as better with 15～20L/h wherein.The time of dynamic extraction is 1～5 hour, serves as better with 2～3 hours wherein.The supercritical extraction process can be used pure CO
2Make extraction agent, also can add ethanol, methyl alcohol, water or acetone in CO
2In as cosolvent, wherein pure CO
2For better.
Supercritical liquid extraction technique is a kind of new bio separation and purification technology of just rising late 1970s.It does not have the separated from solvent problem of traditional solvent, thereby makes the extraction process of natural product that revolutionary improvement take place.Ostrich oil extract through the inventive method acquisition; For the white medicinal extract shape of jade product, kept ostrich oil effective constituent preferably, nutritious; Be the real green organic products that adopts advanced supercritical extraction, can be used for the protective foods exploitation or as the raw material of pharmaceutical compound.
The traditional preparation process method of animal oil and fat mainly is a smelting process.Whether smelting process can be divided into two types of dry method melting and wet method meltings according to adding water.Smelting process makes protein denaturation through heating, thereby the destruction of adipose tissue cell flows out fat.Because heating, cause the destruction of the active ingredient that unsaturated fatty acids in the grease etc. is important easily.
Helpful being of the present invention:
(1) preparation method is reasonable in design, the preparation method is simple, and is easy to operate, and the PT is short, only handles and supercritical CO through raw material
2Extracting and separating can obtain the ostrich oil extract;
(2) because extract the lower and closed-loop operation of temperature, the oxidation and the decomposition of unsaturated fatty acids composition be can avoid preferably, the activeconstituents of ostrich oil and good Penetration Signature kept as far as possible;
(3) material does not contact deleterious organic solvent in the leaching process, no solvent residue, production process environmental protection.
