Abstract

<P>PROBLEM TO BE SOLVED: To provide a method for efficiently and stably harvesting oil having high quality as skin care oil or skin cream and preventing degeneration of its quality. <P>SOLUTION: Fat mass is collected from a slaughtered ostrich body and passed through a chopper to be a minced state. The minced fat mass is put into a steaming cooker and oil is separated with 60-90°C hot water. Activated clay is added to the crude ostrich oil, agitated at 70-80°C for about 10 minutes and filtered by paper filter. Filtered oil is put into a vessel and kept at a state of reduced pressure for ≥1 days to remove odors. Tocopherol (vitamin E) is added to the oil, bamboo charcoal is dipped in the oil in 1/10-1/100 weight of the oil and stood for 10-20 days to enhance transparency and remove the odors. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

Detailed Description of the Invention

The present invention relates to a series of production methods such as extraction, decolorization, deodorization, purification, and oxidation prevention of ostrich oil.

The fatty acid composition of ostrich oil contains not only oleic acid and palmitic acid, but also palmitoleic acid, which is abundant in human sebum.
For this reason, demand for skin creams and cosmetics that can be easily adapted to human skin can be expected. However, a colorless, odorless and highly accurate oil is desired for use in these applications.

General methods for separating and collecting high-quality lipids and oils are as follows: (1) plant raw materials such as rapeseed and olives are mechanical compression or organic solvent extraction; (2) animal raw materials such as pork fat and fish oil Generally, a method (rendering) of heating and boiling with water (steam) is performed.

A method for efficiently extracting and refining oil having a higher purity than fat mass collected from ostrich carcasses has not been clarified.

Problems to be solved by the invention

For animal raw materials such as ostrich, heating (cooking) with water (steam) is generally performed (rendering), but depending on the method of oil separation, extraction, and purification, the extraction rate is low, and the oil has an odor. The quality is not constant, such as occurrence, low transparency, turbidity, or shade of yellow, which is a problem in stably collecting high quality oil as skin care oil or skin cream.

The present invention collects a fat mass from an ostrich carcass while having high freshness, efficiently extracts and separates the oil by the following method, purifies it, and applies an antioxidant treatment to provide odorless for skin care. In this method, it is possible to obtain a high-purity oil having high transparency and low coloration.

Means for solving the problem

In the present invention, the fat mass is separated from the carcass within 24 hours after the ostrich slaughter.
From the separated fat mass, the muscle and other parts other than fat are visually removed with a knife or knife.
The fractionated fat is minced through a chopper with a plate hole of 1 mm to 5 mm.
The minced fat is put into a steam kettle shown in FIG. 1 and oil is extracted and separated with hot water at 60 to 90 ° C.
Activated clay is added to the separated oil in an amount of 1 to 5%, stirred at 70 to 80 ° C. for about 10 minutes, and then filtered through a paper filter.
The filtered oil is transferred to a container, and the pressure in the container is reduced to 600 mmHg or less with a vacuum pump, and the state is maintained for one day or more to remove odor.
Tocopherol preparation (vitamin E) 0.001 to 0.005% is added to this oil to prevent oxidation.
Furthermore, bamboo charcoal with a weight ratio of 100: 1 to 10 is added to the oil and kept for 10 to 20 days to improve transparency and deodorize.
By filtering this oil again with a paper filter, it is possible to collect a highly transparent ostrich oil without odor.

The invention's effect

The effect of the first invention is that, if separation, extraction and purification are performed by this method, ostrich oil can be collected efficiently. The effect of 2nd invention can extract | collect ostrich oil with no odor and high transparency. The effect of the third invention is that the quality of the ostrich oil can be kept high for a long time.

Claims (4)

A fat mass separated from the carcass within 24 hours after sterilization of ostrich is minced by applying it to a chopper with a plate hole of 1 mm to 5 mm, and then put into a steam kettle shown in FIG. Oil extraction method. A purification method in which 1-5% of activated clay is added to the collected crude ostrich oil, stirred at 70-80 ° C. for about 10 minutes, and then filtered through a paper filter. A deodorizing method in which filtered oil is transferred to a container, and the pressure in the container is reduced to 600 mmHg or less with a vacuum pump to maintain the state for one day or more to remove odor. Tocopherol preparation (vitamin E) 0,001 to 0.005% is added to the above oil to prevent oxidation and 1-10 bamboo charcoal is added to the oil weight 100 and kept for 10-20 days to improve transparency and deodorize .
