Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a new oil extraction method for marine animal oil, and in particular, to a new method for extracting marine animal oil.
This invention relates to a method for extracting oil while preventing chemical changes such as oxidation, decomposition, and polymerization as much as possible.

Japanese people have been eating a lot of acute species since their ancestors. Therefore, it is well known from experience that freshness has a great effect on taste. When marine animals are directly eaten, freezing them, for example, is used to maintain their freshness.

Cooking methods have also been researched, and to some extent that goal has been achieved.

Europeans and Americans ingest much more fat protein from cows than Japanese people, such as fat from cows (milk fat).
contains many lower saturated acids and less unsaturated acids. In oil chemistry, the degree of unsaturation of oils and fats is expressed by the iodine value (■-vd哄). Marine animal oil exhibits different vitality in the body than beef tallow, and its effects on the body are faster.

Therefore, it is important to use marine animal oils as food without altering their quality□.

However, the active ingredients of glycerides of highly unsaturated acids, which are the main components of marine animal oils, their higher alcohol esters, and other styrene 5-vitamin A, D, and 'Ili barrels undergo chemical changes such as oxidation, 9 decomposition, and 1 polymerization. Currently, most oil extraction methods are
Hasn't it been done? Marine animal oil is a compound having a highly unsaturated chemical structure as described above, and therefore is easily susceptible to chemical changes. As the main cause of turning marine animal oil rancid.

1) Heating marine animals while still hydrated above their biological temperature.

2) Contact with sunlight (ultraviolet rays, infrared rays, radiation, etc.), oxygen in the air, or other organic components (such as enzymes) can be considered.

1-However, as a conventional method for extracting marine animal oil.

, Assistance: Shifu・□, A method is used to separate proteins and chemically unstable oils. highly unsaturated,
It is a stabilized oil with a chemical structure, so-called hydrogenation, and is used for various purposes as hard flower oil.

This method is a method in which an active ingredient having a highly unsaturated chemical structure is converted into a mere hydrogenated oil, which is merely stabilized by 2, and is made into an oil with a low value of 1.

The object of the present invention is to preserve the active ingredients of marine animal oils having the above-mentioned highly unsaturated chemical structure as much as possible.

It is an object of the present invention to provide a method for extracting marine oil that can be separated without being affected by chemical changes. ' □ That is, 9 The present invention involves freezing a cut-off marine animal □ in pieces at a temperature below the animal's biological temperature, solidifying the moisture contained therein, and drying it directly in the air to remove the moisture.

This is a method for extracting marine animal oil, which is characterized by pressing and separating the oil.

Marine animal oils used in the present invention include:

Marine fish + 臘 + M + Body oil and internal organ oil of mackerel, salmon, cod shark, etc.

Cetaceans, whale body oils, skin oils, internal organ oils, etc.0 In short, the present invention is to extract marine animals in a temporary state that undergoes as little chemical change as possible at a temperature below the biological temperature of the animal, i.e. In order to make the first process more convenient with warm soap that has little deterioration, it is shredded into pieces of about 51W1 and then frozen, the moisture contained in it is solidified, the solidified moisture is sublimated, and it is dried directly in the air. ○If the air is directly replaced with carbon dioxide gas before direct air drying, oxidation during direct air drying can be prevented more easily with S-V, which is replaced with carbon dioxide gas than with air. It's so nice. After removing the moisture, the mixture is appropriately pressed using a milling device to separate the oil. Since the separated oil component retains most of its highly unsaturated chemical structure, it is preferable to directly encapsulate it and store it at a low temperature in the dark, or to convert it into a stable compound. According to the method of the present invention, separation was achieved with almost no chemical changes.
□The above results were confirmed by the following examiner.

Compared to the oil extracted by the conventional method in terms of 1 hue, 2 odor, 6 acid value, and 4 peroxide value, the oil produced by the present invention (9) has a lighter hue, less fishy odor, and lower acidity. One example will be explained below.

Example (1) 8M 250y frozen at -30°C is shredded and contains moisture to protect.

Prevent oxidation as much as possible. Next, evacuate the container directly to remove solid ice and dehydrate it until all small particles are completely removed. Add this dried product
Return the temperature to below 10°C and collect by squeezing.The amount of oil at that time is approximately 20.9.The oil in step 2 is CO, and it is packed into capsules (200"g) at the lowest possible temperature in an air stream. Near 7
,',3001'1g). Store in a cool, dark place until ready for consumption.

Example (2) Frozen cod fish 6002 was frozen and shredded in the same manner as in Example (1).
After completely solidifying the water content, direct air dehydration is performed.
After that, the temperature is returned to +1000 and the oil is extracted by pressing and oil 10
I got 01. The use of carbonic acid gas was the same as in the flow side (1), and the product was encapsulated.
