Problems solved by technology

[0006] There are also relevant patent reports about the extraction method of ostrich oil, but they all adopt solvent (ether, sherwood oil, supercritical carbon dioxide) to extract, and the extraction rate of extraction with organic solvent is very high, but there is a potential safety hazard, and supercritical carbon dioxide extraction is used to avoid Solvent residue and other problems, but the extraction efficiency is greatly reduced
Such as: Patent CN200910021992.5 reports a method for the extraction of ostrich oil and the separation of oil and fat. Ether is used as a solvent to extract ostrich oil, and then the liquid oil and solid fat are centrifuged. This method uses ether as an extraction solvent, but ether is flammable Explosive, and has an anesthetic effect on the human body, there is a great safety hazard in the process of use
Patent CN200910102292.9 reports a supercritical extraction method of ostrich oil. This method avoids problems such as solvent residues, but the preparation method requires large equipment investment, high technical requirements, high production and operation costs, and the extraction of this method The extraction rate is very low, and the extraction rate is only about 40%, which causes waste of raw materials
Patent CN201010120721.8 provides a method for extracting ostrich oil with petroleum ether solvent. This method can make the extraction rate of ostrich oil as high as 90%. However, the main problem of this method is the solvent residue. If the operation is improper, it will easily bring negative effects

Embodiment 1

[0018] Wash the ostrich adipose tissue, mince it with a meat grinder, and freeze it in the refrigerator for later use. Weigh 230g of ostrich adipose tissue, place it in a vertical high-pressure steam sterilizer, add 1500mL of water, set the temperature at 95°C, and extract for 1 hour. First heat to remove cold air, and close the exhaust valve when a large amount of white steam is discharged. , when the temperature reaches 95°C, automatic timing, after 1 hour of extraction, wait for it to cool down automatically, when the pressure gauge shows 0, first open the exhaust valve, then open the lid, take out the extract, filter it with gauze, and filter out the oil slag, pour the oil-water mixture into a separatory bottle, place it in an oven at 40°C, let it stand for stratification, discard the water phase, and separate the oil layer to obtain 114g of ostrich crude oil, which is light yellow solid after refrigerated storage. The yield is 49.56%.

Embodiment 2

[0020] Weigh 200g of ostrich adipose tissue, put it in a vertical high-pressure steam sterilizer, add 1500mL of water, set the temperature at 105°C, and extract for 1h. First heat to remove cold air, and close the exhaust valve when a large amount of white steam is discharged. , when the temperature reaches 105°C, automatic timing, after extraction for 1 hour, wait for it to cool down automatically, when the pressure gauge shows 0, first open the exhaust valve, then open the lid, take out the extract, filter it with gauze, and filter out the oil slag, pour the oil-water mixture into a separatory bottle, place it in an oven at 50°C, let it stand for stratification, discard the water phase, and separate the oil layer to obtain 128g of ostrich crude oil, which is light yellow solid after refrigerated storage. The yield is 64.00%.

Embodiment 3

[0022] Weigh 210g of ostrich adipose tissue, put it in a vertical high-pressure steam sterilizer, add 1000mL of water, set the temperature at 115°C, and extract for 1h. , when the temperature reaches 115 ℃, automatic timing, after extracting for 1 hour, wait for it to cool down automatically, when the pressure gauge shows 0, first open the exhaust valve, then open the lid, take out the extract, filter it with gauze, and filter out the oil slag, pour the oil-water mixture into a separatory bottle, place it in an oven at 60°C, let it stand for stratification, discard the water phase, and separate the oil layer to obtain 138g ostrich crude oil, which is light yellow solid after refrigerated storage. The yield is 65.71%.

Abstract

The invention belongs to the technical field of chemical invention, particularly relating to a preparation method and application of refined ostrich oil. The preparation method of the ostrich oil comprises the following steps: taking ostrich fat tissue as a raw material, mincing, putting into an extraction device, adding water, pressurizing to extract, and filtering and separating to obtain crudeostrich oil; melting the crude ostrich oil, adding dilute aqueous alkali, stirring, standing for layering, and collecting an oil phase; carrying out centrifugal dehydration after an oil layer is melted; collecting an upper layer of clarified oil phase; and drying in vacuum to remove trace moisture so as to obtain the refined ostrich oil. The ostrich oil disclosed by the invention can be used for preparing cosmetics, medical paste and body surface inflammation resistant drug. The preparation method has the advantages of simple technology, small equipment investment and high yield, is convenient to operate, does not contain organic solvent and is environmentally-friendly.

Description

technical field [0001] The invention belongs to the technical field of chemical inventions, and in particular relates to a preparation method and application of refined ostrich oil. Background technique [0002] The African ostrich (Struthio camelus) is the largest bird among birds. It may have evolved from flying ancestors, but it is flightless itself. It is a special animal in Africa, mainly distributed in the south of the Sahara Desert. All African ostriches in the world today belong to the same race, and can be divided into 4 existing subspecies and 1 modern extinct subspecies in biological classification. [0003] Wild ostriches belong to the protection category of the Convention on International Trade in Endangered Species of Wild Fauna and Flora, and domesticated ostriches are now being developed and utilized. Domesticated ostrich refers to the production population selected by artificial hybridization, which can be developed and utilized as a commodity circulation. ...
