Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a fine powdered nutritional supplement from eel or eel bone as a nutritional supplement such as calcium.

[0002]

2. Description of the Related Art It is widely known that boiled and dried animal bones are generally used as nutritional supplements such as calcium. Most of these fine powders consist of terrestrial animals such as cows and pigs and fishes such as horse mackerel and sardine that live near the sea surface, and do not require special techniques for production.

[0003] Animal bone contains various mineral components including calcium, and is used for human health such as prevention of osteoporosis. However, the fact is that bones of animals containing calcium phosphate as a main component are not always welcomed in terms of low absorption rate and containing harmful trace components. In contrast, the bones of eels and eel eggs laid or resident in the deep sea (hereinafter referred to as “eels”) contain a large amount of calcium and minerals, which are important as nutrient sources for the elderly and people with weak bones. Role is expected. Bone of eel and the like is a by-product generated when making eel kabayaki and the like, and is advantageous in manufacturing cost.

[0004]

However, when producing fine powder by crushing bones of eel and the like, heating, drying and crushing are performed in the same manner as making fine powder from sardine, horse mackerel, and mackerel bone. However, it is difficult to separate the bone marrow fluid from bones of eels and the like, so it is not possible to obtain a fine white powder that is clean and white, and the bone marrow penetrates and smells remain, making it unsuitable for drinking. There is.

[0005] Therefore, an object of the present invention is to remove the bone marrow fluid from eel bones or the like so that the bones of the eel bones and the like which are suitable for drinking and have a high absorption rate can be used as raw materials. To provide a method for producing a fine powder nutritional supplement.

[0006]

According to the first aspect of the present invention, after separating bone and attached meat from fish bones taken out from eel or conger, the separated bone is granulated to form bone grains. In the method for producing a bone fine powder obtained by drying and then pulverizing, the above-mentioned bone particles are immersed in a salt solution having a salt concentration of 10% or more for 6 hours or more, and the salt is washed away to remove bone marrow fluid from the above-mentioned bone particles. A method for producing a fine powder nutritional supplement using eel or conger bone as a raw material, comprising drying defatted bone grains after drying.

According to a second aspect of the present invention, the concentration of the saline solution is set to 1
0 to 22%, the immersion time is 6 to 12 hours,
This is a method for producing a fine powder nutritional supplement using eel or conger bone as a raw material.

[0008]

Next, the manufacturing method of the present invention will be described with reference to the drawings. FIG. 1 shows an outline of the manufacturing process of the present invention, and the reference numerals in this figure use arithmetic numerals for the process names and are surrounded by ellipses indicated by right-pointing arrows from some process frames. Alphabet is used for the name. These names are temporary names given to the intermediate products produced by the process.

First, it is necessary to supply raw materials as a preparatory act before entering this step. The raw material is fish bone that comes out when it is cut to cook eel etc. This bone a is a blanching 1 that separates the head and internal organs from the remaining fish bone part after removing the meat part used for kabayaki etc. (In the stage of preparing eel dishes). At this time, care must be taken because if the bone a is not washed immediately at the time of separation, blood may permeate the bone and may result in coloring of the final product. Normally, these bones a are collected in a frozen state, but of course, in the case where the manufacturing facility of the present invention is located near a processing plant for eel or the like, it is also possible to supply the bones without freezing. This is more cost effective.

[0010] The bone a separated in the branching step 1 from the eel or the like supplied to the production facility of the present invention is as follows:
The first cleaning step 2 is entered. In the first washing step 2, for example, 30 kg of bone a is put into a boiling boiler at a time, and is boiled again and taken out after a lapse of 10 to 15 minutes. Further, the mixture is put into a food mixer, and the mixture is rotated for about 3 to 5 minutes with almost half the amount of water to agitate both to remove only the liquefied meat juice. In the first washing step 2, the operations of stirring and removing the gravy are performed in two steps.
By repeating this process up to three times, a bone having no gravy or the like attached to the surface can be obtained.

The bone from which the meat has been removed by the primary washing step 2 is subjected to a mincing step 3. Here, the bone is put into a mincing machine and finely chopped into rice grains. Here, the bone in the rice grain state is referred to as a bone grain.

Next, the bone b is subjected to a secondary washing step 4
The deposits attached in the mincing step 3 and the like are removed. In the secondary washing step 4, the bone particles b are simultaneously put into a food mixer, for example, for about 5 kettles (about 150 kg), and the attached matter is washed away by stirring the mixture with an almost double amount of water for 10 to 15 minutes.

[0013] Bone b washed in the secondary washing step 4
After draining, in preparation for the next saline immersion process,
For example, bags are packed in retort bags (mesh bags) at a ratio of 400 cc of water to 500 g of bone particles. The bone particles b put in the retort bag are put into a high-concentration saline solution tank together with the retort bag and subjected to the next salt solution immersion treatment step 5a.

The salt solution immersion step 5a is a step for removing the bone marrow fluid remaining in the core of the bone b using the osmotic pressure of sodium. The immersion time is 6 to 12 hours, preferably 8 to 10 hours. The bone marrow fluid in the bone b is removed by suction into a concentrated saline solution by osmosis.

Next, the bone particles b from which the bone marrow fluid has been removed in the salt solution immersion treatment step are subjected to the next tertiary washing step 5b to separate the oil and fat components from the bone marrow from the bone particles. Here, the operation of placing the bone b in a food blender together with, for example, approximately three times the amount of water and stirring for 15 to 20 minutes is repeated two or three times. Thereby, the fat component of the bone marrow is completely removed from the bone grain b. Here, a bone from which the oil and fat component of the bone marrow is completely removed from the bone grain b is referred to as a fine bone, and is represented by a symbol c. The salt water immersion treatment step 5a and the tertiary washing step 5b are combined to form a bone marrow fluid removing step 5.

Next, the fine bone c is drained and then dried in a hot air drying step 6. In this hot air drying step 6, the fine bone c is put in a hot air drier and dried by heating at a temperature of, for example, 65 ° C. for several minutes.

The dried fine bone c is then crushed in a crushing step 7 to become a powder d. In the pulverizing step 7, the fine bone c is put into a rotary pulverizer, and an impact is applied to the pulverized c.
Make 50-200 mesh powder. The powder d obtained by the pulverization will be of a quality suitable for drinking in the next sterilization / deodorization step 8.

In the sterilization / deodorization step 8, the powder d is put into an infrared irradiation device and irradiated with infrared rays (electromagnetic waves) having a wavelength of, for example, 3 to 12 μm, particularly far infrared rays having a wavelength of about 5 μm.
Performs sterilization and deodorization, and activates cells.
Irradiation with far infrared rays is suitably for 7 to 12 minutes. If the time is less than 7 minutes, the effects of sterilization and deodorization are insufficient, and if the time exceeds 12 minutes, the quality is deteriorated, which is not preferable.

Here, the powder sterilized and deodorized is sieved only in a fine powder in the next particle sorting (sieving) step 9. In this step, for example, a fine powder e of 200 mesh or less is sieved from the powder using a classifier equipped with a 200 mesh sieve. 200 screened
The fine powder e having a mesh or less can be drunk as it is with a spoon or the like and put into a mouth. The fine powder thus produced is bottled or bagged to produce a fine powder nutritional supplement product f.
It can be shipped as

In the above-mentioned steps other than the bone marrow fluid removing step, the same fine powder nutritional supplement can be obtained by other means.

[0021]

According to the present invention, it is possible to reliably obtain a fine powdered nutritional supplement made from bones such as eel and the like, which is white and has no harmful components and is easy to drink. This fine powder nutritional supplement has a very high calcium content, which makes it easier to drink and contributes to an increase in demand. As a result, the elderly skeleton such as osteoporosis and other health benefits It is possible to contribute to improvement.
