Abstract
The invention provides a method for extracting ostrich oil, which comprises the following steps: grinding refrigerated ostrich adipose tissues, adding a petroleum ether solvent for extraction, carrying out reflux extraction at 40-65 DEG C, filtering and mixing the extract, and distilling under the conditions with the temperature being 40-45 DEG C and the vacuum degree being 70-95kPa to remove the extracting solvent, thereby obtaining the ostrich oil. The method of the invention has the advantages of simple process, convenient operation and low equipment investment. Moreover, the extraction rate of the ostrich oil can reach 90 percent. Compared with the prior art, the extracted ostrich oil product has the functions of keeping the skin wet, resisting the corrosion, easing the pain in joints and muscle, preventing the inflammation, and promoting the wound healing.
Description
Technical field
The invention belongs to the extraction and the working method of natural product, relate generally to a kind of animal grease preparation method of extract and products thereof.
Background technology
Ostrich is at present maximum in the world birds, originates in Africa, like short of rainly in arid, and living in competent desert of illumination and grassland, mainly is food with the plant.Ostrich is good at and runs, and endurance is pure, and dash speed can reach per hour 70 kilometers, but ostrich can not fly, and belongs to cursorial birds, again because of its breastbone is flat, and does not have a carina, and belongs to flat chest catalogue.In addition, wild ostrich is included by " CITS ", belongs to world's protection species.
Ostrich has high economic worth, and main products comprises meat, Pi Hemao.Ostrich meat is " three low a height " meat, i.e. lower fat, low in calories, low-cholesterol and high protein are regarded as the main body food of 21 century by WTO expert.Ostrich skin and feather then can be used as the important source material of famous and precious leather, advanced processes product and high-grade ornament.In recent years, the aquaculture development of domestic ostrich is very fast, and the amount of livestock on hand of ostrich reaches thousands of, becomes the first ostrich in Asia and cultures state.But owing to many-sided reason, the market of ostrich goods mainly in overseas, the economic benefit fluctuation that ostrich is cultured is bigger.Therefore, the comprehensive exploitation that strengthens ostrich is the basic outlet of China's ostrich aquaculture, particularly to the development and use of ostrich oil.
Ostrich oil derives from ostrich fat, mainly form by lipid acid such as palmitinic acid, stearic acid, oleic acid, linolic acid, but its unique lipid acid is formed, and makes it have unique biochemistry and physico-chemical property, and extremely application prospects is arranged in health care and cosmetic industry.Ostrich oil has superpower penetrating power, relaxed muscle rapidly, and alleviating fatigue can also be repaired damaging cells fast, promotes tissue regeneration.Ostrich oil has tangible anti-inflammatory analgetic effect, makes it aspect treatment rheumatosis, sacroiliitis, cervical spondylosis, prolapse of lumbar intervertebral disc and the wound good result arranged all.
At present, the report of domestic introduction and health care of research ostrich oil and medical functions increases gradually.Patent CN200610105029.1 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.Patent CN 200910021992.5 has reported a kind of extraction of ostrich oil and oil, fat separation method, adopts ether to make the solvent extraction ostrich oil, then liquid oil of centrifugation and solid-state fat.The technological deficiency of this method is: ether is inflammable and explosive limiter stage reagent, exists the potential safety hazard that can not be ignored in the use, so suitability for industrialized production is very difficult.Patent CN 200910102292.9 discloses a kind of supercritical extraction method of ostrich oil.This method has been avoided dissolvent residual, and has the advantage of environmental protection.The weak point of this technology is that facility investment is big, the technical requirements height.
Summary of the invention
The present invention is intended to keep to greatest extent utilize the normal reflux extractive technique on the basis of ostrich oil activeconstituents and good characteristic, and providing a kind of is that extraction solvent extracts the greasy method of ostrich with the sherwood oil.The present invention is achieved through the following technical solutions: with the ostrich fatty tissue after the refrigeration is raw material, rub into particulate state minced meat, pack in the extraction element, every gram raw material adds the petroleum ether extraction solvent of 10～30mL, in 40～65 ℃ of refluxing extraction 1～2 time, extraction time 1～3h is with extracting solution suction filtration, merging; Then, be under the condition of 70～95kPa at 40～45 ℃ with vacuum tightness, extraction solvent is removed in distillation, obtains the ostrich grease.The ostrich oil fat prod normal temperature that obtains is light yellow oily liquid down, and refrigeration is placed as lurid solid.
In ostrich fatty tissue solvent extraction process, used extraction solvent is a sherwood oil, and its outward appearance and proterties are: colourless transparent liquid has the kerosene smell, boiling range: 30-90 ℃ serves as better with 40-60 ℃ wherein.
In view of the present situation of ostrich oil extracting method, it is the new method for extracting of solvent extraction ostrich oil with the sherwood oil that the present invention proposes a kind of.The characteristics of this method are, technology is simple, and is easy to operate, low equipment investment, and also the extraction yield of ostrich oil can reach 90%.Compared with prior art, the invention has the advantages that: technology is simple, and is easy to operate, low equipment investment, and also the extraction yield of ostrich oil is higher.The ostrich oil product has the maintenance skin wet, and is anticorrosion, alleviates the function of joint, myalgia, anti-inflammatory and promotion wound healing.
