ていた。BACKGROUND OF THE INVENTION Arachidonic acid
acid, all cis 5,8,11,14-eicosatetraenoic acid) is at the beginning of the arachidonic acid cascade, a series of enzymatic reactions that biosynthesize various bioactive substances such as prostaglandins, leukotrienes and the like. It is a highly unsaturated fatty acid and one of the essential fatty acids. Arachidonic acid is also found in breast milk and is thought to be involved in the growth process from fetal to infancy,
It is desired to mix arachidonic acid with infant formula. For such purposes, it is necessary to formulate a safe product containing arachidonic acid with as high a purity as possible in order to avoid contamination with unnecessary substances. Conventionally, arachidonic acid-containing lipid products have been obtained by extracting from fish oil or egg yolk oil, or by producing a triglyceride containing a large amount of arachidonic acid in a bacterium such as Mortierella and purifying it from the cells.

On the other hand, in the case of a method using a microorganism, there is a risk of contamination by a protein derived from the microorganism, and it has been difficult to say that the method is perfect in terms of product safety.

る。Examples of the organic solvent include alcohol solvents such as methanol, ethanol, isopropanol and octanol, and chlorinated solvents such as hexane, acetone and chloroform and methyl chloride. These can be used alone or in combination. However, from the viewpoint of safety and the like, ethanol or hexane or a mixed solvent thereof is suitable, and ethanol or a mixed solvent of ethanol and hexane is preferable. The mixing ratio of ethanol and hexane is arbitrary, but ethanol / hexane (volume ratio) =
0.1-10 are preferable, and 0.5-2 are more preferable. The amount of the solvent used is at least an amount that can immerse the dry raw material to be extracted,
About 2 to 10 times, preferably about 3 to 5 times by weight the dry raw material
Use twice the amount of solvent. The extraction temperature may be within a range where the quality of the arachidonic acid-containing phospholipid does not deteriorate, and is usually about 1
The temperature is 0 to 80 ° C, preferably 30 to 70 ° C, more preferably 50 to 70 ° C. When the extraction treatment is performed using ethanol alone, it is preferable to maintain the temperature at or below the reflux temperature of ethanol. If the temperature is exceeded, the phospholipids are liable to be altered and colored. The extraction time varies depending on the type and state of the raw materials, the processing temperature, the type of the solvent and the amount used, but is generally about 0.5 to 5 hours, preferably about 1 to 2 hours.
The extraction operation may usually be performed once, but may be repeated several times as desired. In order to increase the extraction efficiency, the raw material may be appropriately chopped or extracted with stirring. The extract thus obtained contains, as a main component, a phospholipid containing arachidonic acid at a high concentration among the fatty acids constituting the phospholipid, and contains a mixture of the phospholipid and triglyceride.

The solvent is distilled off at 60 ° C. or lower. By performing the treatment at such a low temperature, oxidation, deterioration, decomposition, alteration, and the like of the extracted components such as arachidonic acid-containing phospholipids in the raw materials can be prevented, and the object of the present invention can be produced in a high quality state. As a means for distilling off the solvent, a distillation treatment is preferable. Distillation is performed under reduced pressure, preferably under high vacuum (5-30 mHg). The solvent recovered in this way can be reused for a new extraction process. Any commercially available distillation machine is used for distillation,
In order to completely remove the residual solvent, a falling film type or centrifugal type molecular still is preferred. The conditions for molecular distillation are not particularly limited, but the temperature is 70 ° C. or less, and the degree of vacuum is 10 −5 to 0.1 m.
At mHg, preferably 10 −3 mmHg, circulation may be performed as many times as necessary to remove the solvent. The number of circulations is arbitrary, but usually about 3 to 5 times is sufficient. In addition, a purified product obtained by molecular distillation or the like is allowed to coexist with a large amount (about 2 to 10 times) of acetone, and phospholipids, which are insoluble components, are separated and collected, whereby the content of arachidonic acid-containing phospholipids in the extract is determined. Can be further enhanced. Next, acetone is removed at a low temperature by a freeze-drying method or the like to obtain a final product.

After homogenization, the mixture was extracted at 60 ° C. for 2 hours while standing, and the extract was filtered. The filtrate was concentrated under reduced pressure of 30 mmHg in a hot bath at 70 ° C. using a rotary evaporator to obtain a concentrate containing 2 to 4% by weight of ethanol.
Next, the concentrate is heated at a product temperature of about 60 ° C and an evaporation surface temperature of about 100 ° C.
The mixture was subjected to a molecular distillation treatment three times at a temperature of 65 ° C. and a falling temperature of 65 ° C. to obtain a paste-like extract (total lipid). The extract was added to about 5 times the amount of acetone, and the mixture was stirred. Then, insoluble components were filtered off and dried at 30 ° C. in vacuo to obtain phospholipids. Further, for each of the above total lipids and phospholipids, hydrolysis of lipids and methyl esterification of fatty acids were performed by the hydrochloric acid-methanol method (10% hydrochloric acid / methanol solution, heating at 80 ° C. for 3 hours). This was subjected to gas chromatography to analyze the constituent fatty acids of each lipid, and particularly the arachidonic acid content was determined. Table 2 shows the results. In Table 2, lipid content (% by weight) = (weight of total lipid / weight of dried organ) × 100,
Phospholipid content in total lipids (% by weight) = (weight of phospholipids / weight of total lipids) × 100, and arachidonic acid content in total lipids or in phospholipids (% by weight) is determined by the constituent fatty acids of each lipid. It is a content ratio of an arachidonic acid component therein.

る。Table 2 shows that extracts from liver and spleen contain high concentrations of arachidonic acid as a constituent fatty acid of total lipids and phospholipids, and these organs are suitable as raw materials of the present invention. I have. In the case of the small intestine, the content of total lipids is low, but the content of arachidonic acid among the constituent fatty acids of phospholipids is high, so that it can be used as a raw material. However, the stomach and large intestine are considered to be unsuitable as raw materials in terms of the arachidonic acid content of total lipids and phospholipids. The phospholipids obtained in this example, especially products obtained from the liver, spleen, and small intestine, were compared with conventional phospholipid products from yolk (the content of arachidonic acid in the constituent fatty acids was 1 to 5% by weight). And the arachidonic acid content of the constituent fatty acids is high,
Because it is rich in phospholipids, it is suitable as an additive to a composition enriched with arachidonic acid, especially an infant milk powder.

Further, as a result of analyzing the obtained methyl ester of the constituent fatty acid of each lipid by gas chromatography, the total lipid content was 15.7%; the arachidonic acid content in the total lipid was 18.5%; Lipid content 41.7%, arachidonic acid content 2 in phospholipids
