Problems solved by technology

In 2003, Zhang Wenqing of East China University of Science and Technology and others carried out the experimental research on "extraction and comprehensive utilization of ostrich oil" for Shanghai Pudong Xiechuang Ostrich Industry Co., Ltd.; Extracted from living wild ostriches; Dalian Ruifang Biochemical Products Co., Ltd. said that they have ostrich oil for sale; the above companies only say "extraction" or have conducted "extraction research", but there is no public report on the extraction method
So up to the present, there are no technical publications and patent documents related to ostrich oil at home and abroad.

Embodiment 1

[0018] (1) Weigh 200 g of fresh ostrich fat, wash it with tap water, and dry it at room temperature. Put it into a gradient type multifunctional extractor, add 400ml of ether, reflux extraction at 45°C for 2h, and cool the extract to room temperature. (2) Filtrate the extract, concentrate the filtrate at 40° C. under stirring, recover ether, and obtain primary ostrich fat. (3) then prepare the fine ostrich oil at 45 ℃, vacuum degree 0 -4 Concentrate under reduced pressure at Mpa for 1 h, remove the residual ether solvent, and obtain 189.1 g of refined ostrich oil with a yield of 94.55%. (4) Place the refined ostrich fat obtained after concentration at 25° C. for 20 h, and centrifuge to obtain 90.77 g of refined liquid ostrich oil and 98.33 g of refined solid ostrich fat.

Embodiment 2

[0020] (1) Weigh 300 g of fresh ostrich fat, wash it with tap water, and dry it at room temperature. Put it into a gradient multifunctional extractor, add 600ml of diethyl ether, reflux extraction at 40°C for 3h, and cool the extract to room temperature. (2) Filtrate the extract, concentrate the filtrate at 45° C. under stirring, recover ether, and obtain primary ostrich fat. (3) Then prepare the refined ostrich oil at 40 ℃, vacuum degree 10 -3 Concentrate under reduced pressure at Mpa for 2 h to remove residual ether to obtain 286.2 g of refined ostrich oil with a yield of 95.4%. (4) The refined ostrich fat obtained after concentration was placed statically at 25° C. for 24 hours, and centrifuged to obtain 137.83 g of refined liquid ostrich oil and 148.37 g of refined solid ostrich fat.

[0021] Since the temperature of the whole technological process of the present invention does not exceed 45 DEG C, the temperature is low, the active ingredients in the ostrich oil can be ...

Abstract

The invention discloses an method for extracting ostrich oil and separating oil and grease, which comprises the following steps: firstly, cleaning and drying fresh ostrich fatty, placing the ostrich fatty into a graded multifunctional extraction apparatus, adding aether, refluxing under 40-45 DEG C and extracting for 2-3h, cooling extracting solution to the room temperature and filtering; secondly, mixing and concentrating the filtered extracting solution under 40-45 DEG C, recovering the aether, and obtaining the primary ostrich oil grease composite; thirdly, vacuumizing and reducing and concentrating the primary ostrich oil grease composite under 40-45 DEG C for 1-2h, removing the residual solvent, and obtaining the fine ostrich oil grease composite; fourthly, stewing the obtained fine ostrich oil grease composite under 20-25 DEG C after being reduced and concentrated for at least 20h, and then separating eccentrically, and obtaining the fine liquid ostrich oil and the solid ostrich grease.

Description

technical field [0001] The invention relates to a method for deep processing of agricultural by-products, in particular to a method for extracting refined ostrich oil and separating oil and fat. Background technique [0002] Native to Africa, the ostrich is the largest omnivorous bird in the world. Its meat is not only delicious, but also has the advantages of high protein content and low cholesterol, which is especially suitable for the taste of modern consumers. In addition to edible meat and eggs, ostriches have many uses. Ostrich skin can be made into high-quality leather, which is soft, durable, beautiful, breathable, strong in tension, not easy to age, and can be curled. Not only has a long service life, but also increases with time, and the surface of the product is brighter, which is very popular among consumers. The large feathers of ostriches are decorations for European and American women's clothes and hats, and the short tail feathers can be made into "ostrich ...
