Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a method for removing colored and odorous components from orange roughy oil obtained from deep-sea bone color and for purifying it.

(b) Conventional technology Orange roughy oil is extracted from the skin, subcutaneous fat, or head of orange roughy, a deep-sea teleost fish that lives in the deep seas of various parts of the southern hemisphere, using a boiling method.

It is an orange oil obtained by dehydration. This one is C
A wax ester having an even number of carbons from 3° to C46,
In addition to being used in cosmetics due to its light, sticky feel, it can also be used in high-end lubricants, polishing waxes, textile and pharmaceutical industries, and its sulfurized oil in the lubricant industry.

Orange roughy oil is purified by deodorization, decolorization, or distillation depending on the purpose of use.

To give an example of a purification method, decolorization is performed by mixing orange roughy oil and 1 to 2% of clay, heating the mixture at 105° C. for 915 to 30 minutes, and then removing the clay by pressure filtration. Moreover, deodorization is performed by blowing steam under reduced pressure in a deodorizing device and treating at 200 to 250° C. for 1.5 to 2 hours.

(C) Problems to be Solved by the Invention However, in the decolorization method, only a part of the colored components in orange roughy oil are decolorized, and it is difficult to make the oil completely colorless. Further, even in the above deodorizing method, the fishy odor of Orange Lasoffee crude oil remains, and the odor cannot be completely deodorized. For this reason, it is difficult to refine and produce colorless and odorless orange roughy oil using conventional decolorization and deodorization methods, and it is difficult to use it in the cosmetics and pharmaceutical industries, which require a high degree of purification.

Therefore, an object of the present invention is to provide a refining method capable of obtaining colorless and odorless orange roughy oil, which is also suitable for the above-mentioned uses.

(e) Means for Solving the Problems As a result of intensive research to solve the above-mentioned problems of conventional decolorization and deodorization methods, the present inventors have found that silica gel It was discovered that odorous components are selectively adsorbed, and that orange lasso oil itself is difficult to adsorb, and based on this finding, the present invention was completed.

That is, the method for refining orange roughy oil of the present invention involves adding a solvent to orange roughy crude oil obtained from the skin, subcutaneous fat, and head of orange roughy, and bringing these into contact with silica gel to extract the orange roughy oil from the orange roughy oil. It is characterized by removing colored and odorous components.

The shape of the silica gel particles used in the present invention is 180~
Preferably, it has a spherical shape of 500 μm. Commercially available silica gels such as Microbeads 4B (manufactured by Fuji Davison) and Microsphere Gel (manufactured by Asahi Glass Co., Ltd.) can be used.

The solvent used in the present invention is petroleum ether.

Hydrocarbon solvents such as hexane are preferred, or mixtures thereof can be used. The amount of these solvents used is preferably 1 to 10 times the amount of orange roughy oil. If the amount is less than this, the adsorption operation using silica gel will not proceed smoothly, and if it is more than this, the cost for recovering the solvent will be too high, which is uneconomical.

The stirring temperature is not particularly limited, but it needs to be below the boiling point of the solvent.

Further, the time period for which the mixture of orange roughy oil and the solvent is brought into contact with the silica gel is preferably in the range of 0.5 to 4 hours.

(e) Examples Example 1 1 kg of orange roughy oil was dissolved in 101 hexane, 2.5 kg of silica gel (Microbeads 4B manufactured by Fuji Davison) was added, and the mixture was stirred at 25°C for 3 hours. Perform decolorization and deodorization treatment. Silica gel was removed from the resulting treatment liquid and hexane was distilled off to obtain 825 g of purified orange roughy oil.

Example 2 500 g of orange roughy oil is dissolved in 31% ethanol, 1 kg of silica gel (Microsphere Gel manufactured by Asahi Glass Co., Ltd.) is added, and the mixture is stirred at 25° C. for 3 hours to perform decolorization and deodorization treatment. The silica gel was removed from the resulting treatment liquid and ethanol was distilled off to obtain 430 g of purified orange roughy oil.

Comparative Example 1 Add 2% white clay to 1 kg of orange roughy oil,
After heating and stirring at 5° C. for 30 minutes, the white clay was removed using 0.2% Celite and decolorization was performed. Next, the mixture was deodorized by heating at 200° C. for 2 hours while blowing steam under reduced pressure to obtain 890 g of purified orange roughy oil.

Table 1 shows the results of measuring the chromaticity and odor of each of the above refined oils.

Table 1 (f) Effects of the Invention According to the present invention, it is possible to produce colorless, odorless refined orange roughy oil without fishy odor, which could not be obtained by conventional refining methods.

Therefore, this product is particularly suitable for use in cosmetics, pharmaceuticals, etc., and is of great industrial significance.
