Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a method for producing a fish and shellfish extract, and in particular, cadmium, which is contained in a large amount in internal organs such as scallops, is contained at a content acceptable value or less for use in food, feed, and fertilizer applications. This is a method for producing a seafood extract in which shellfish poison is hardly detected.

[0002]

2. Description of the Related Art Heretofore, in this type, the following has been done. Most of the naturally-occurring scallops and ground lacquer shells live in the sandy bottom of the sea and are caught by a fishing method called girder-pulling. It holds the sand mud and shells. In addition, it has been clarified that most of cadmium, which is considered to be caused by the food chain, and shellfish toxins that appear with time are concentrated and concentrated in the midgut gland of the internal organs. For cadmium, the content acceptable standard value is shown for each application of food, feed and fertilizer, and for shellfish poisoning, the content regulation value is shown by the shellfish poison notification. Cadmium is one millionth of a unit of pp
m and shellfish poison are expressed in units of mouse units, and are usually invisible, and it is difficult to remove them directly from the actual organism. When processed into fishmeal meal, cadmium remains concentrated and remains in excess of the content allowed in feeds and fertilizers. Of the shellfish poisons, water-soluble shellfish poisons almost disappear by heat sterilization, but fat-soluble shellfish poisons are heat-stable, so oils and fats must be removed. For this reason, the internal organs such as the midgut glands that are by-products of scallop processing are dumped as landfill or incinerated as industrial waste.However, a peculiar odor, air pollution, and soil pollution are generated during disposal. It has been a source of pollution that induces pollution, such as the concern about, and significantly impedes life and the natural environment.

[0003]

The problems described in the prior art have the following problems. The ratio of each part of the scallop is 3 to 5 during the hypertrophied period of the sperm and ovary.
Seasonal fluctuations are large between June and July in the spawning season, but on average 51.7% of shells, 13.8% of scallops, and 3.7 of midgut glands.
%, Gills 4.7%, mantle 8.2%, sperm / ovary 3.9%
And there is a lot of water retention. If this is replaced with the composition ratio of the internal organs excluding the trabecular bone, the gut gland 18%, gills 23%, mantle 40%, and sperm / ovary 19%. Cadmium and shellfish poisoning are restricted to 18% of the midgut glands of the internal organs excluding the scallops, but gills hug a lot of sand and mud along with a sticky slime and The sperm and ovaries are not useful. Further, selective separation of only the midgut gland from fresh viscera is not accompanied by workability, and it is extremely difficult to directly remove cadmium and shellfish poison from the living body of the midgut gland. For this reason, the internal organs of scallops are dumped, landfilled or incinerated without treatment such as volume reduction or reduction, thereby inducing pollution and obstructing the daily life and natural environment.

The disposal method of burying in the soil induces unpleasant odors and flies due to the decay of oils and proteins from the landfill site, and becomes a storage place of a pollution source such as concern about soil pollution. The disposal method of incineration is to incinerate the internal organs of seafood that has a high water content and has a tendency to perish with a direct flame at 600 to 800 ° C, and it accumulates in large quantities without dehydration volume reduction, keeping freshness, and aging over time. In addition to the generation of peculiar odors including trimethylamine odor and hydrogen sulfide due to the heating and incineration of the material whose freshness has deteriorated, air pollution such as the scattering of cadmium and fly ash in the air, which significantly impairs daily life and the natural environment To do. The present invention has been made in view of the above circumstances, by embracing a large amount of sand and mud like scallops, shell fragments, and disposing of cadmium, seafood internal organs containing shellfish poison, etc. as industrial waste. The cadmium content of the extract of the protein digestion solution is a food product, in which a digestion product is produced by a fermentation process of a biochemical method of a protein that is a pollution source of the proposed pollution, and the substance is converted into an amino acid state and recovered.
It is an object of the present invention to provide a method for producing a fish and shellfish extract in which the content of the feed and fertilizer is less than the permissible level for use disposal and almost no shellfish poison is detected. The present application has been made in view of such problems of the conventional technology, and an object of the present application is to provide a device capable of solving the above problems.

The cadmium content of this extract is below the content allowed for the disposal of food products. The blending preparation ratio for producing the fermentation raw material in this treatment is not limited to the examples.

Cadmium in the midgut gland exists in the form of a salt such as a carbonate and a sulfide in addition to an organic bond in which it binds to a protein. Both fresh and boiled water-soluble proteins and organic bound and free cadmium can be eluted and transferred to washing water and bleached water in a considerable amount by washing with water and bleaching.
Cadmium in an organic state, which is present in the internal organs such as the midgut gland of fresh fish, can stabilize its binding form with the protein by heating to coagulate the protein. According to general literature and research announcements by public testing and research institutes, the cadmium content of shellfish is 8.31 to 5.09 ppm of scallop viscera and oyster shellfish of 0.1.
413ppm, scallop column 0.365-0.113pp
m, octopus 0.219ppm, blue clam 0.218〜
It is within the range of about 0.4 to 0.2 ppm at 0.072 ppm. The cadmium content of each part of the scallop used as a sample was 30 ppm for midgut gland, 7.4 ppm for internal organs excluding scallop,
The ovary had 3.2 to 2.8 ppm and the mantle had 0.54 ppm.

[0012] The cadmium content of the broth obtained in the most steaming step of raw shellfish at the time of manufacturing products such as dried scallops is 3.1 ppm,
The boiled guts excluding the scallops are 22 ppm, and this boiled gut 1
On the other hand, boiled broth 1 was added, enzyme-treated, and filtered with filter paper to obtain a protein digestion solution having a cadmium content of 2 ppm and a squeezing residue of 38 p.
pm. The cadmium content of the broth obtained by washing and steaming the fresh offal produced as a by-product during the production of frozen scallops is 1.7 ppm, and the boiled offal is 19 ppm. The cadmium content of the protein-digested solution that had been enzyme-treated and filtered through a filter paper was 1.8 ppm, and the squeezing residue was 30 ppm. Brix 4 for protein digestion
5, the cadmium content of the concentrated solution up to Brix 50 is 7.4 ppm, but a precipitate is generated by static sedimentation separation, and cadmium and an organically bound protein are also precipitated.
The cadmium content of this supernatant was 2.1 ppm.
Cadmium is reduced to 19 ppm by exposing boiled guts with a cadmium content of 22 ppm to water for approximately 2 hours. From this boiled viscera, the mantle, gill, and sperm / ovary of parts other than the midgut gland are crushed. For this crushed material, 1 brute liquid of live gut is mixed, treated with an enzyme, and digested with a filter paper. The cadmium content of the liquid was 0.94 ppm. The second cooked broth 1 obtained by separating the mantle from the boiled internal organs, washing it, exposing it to water, crushing the material, and boiling the scallops against this crushed material 1.
No cadmium was detected in the protein digested solution containing the enzyme, treated with enzyme, and filtered with filter paper.

From this example, both fresh and boiled offal can be washed with water and sufficiently exposed to water, and a considerable amount of water-soluble protein and organic-bonded and free cadmium can be eluted and transferred to washing water and bleached water. To obtain a protein digestive liquid that can be overwhelmingly left over in the squeezing residue of the digestion product produced by the fermentation operation and that is less than the content allowable for the disposal of foods, feeds, and fertilizers by preparing the materials that make up the fermentation raw material. You can Also,
After concentration, the cadmium content in the digestive fluid can be reduced by further precipitating the protein in an organically bound state with cadmium by stationary sedimentation separation. The content of cadmium in foods is based on the specifications of rice listed in Food D, Article 1 of the Food Hygiene Law, the acceptance standard of cadmium content, 1.0ppm of brown rice, and 0.9p of polished rice.
It is applied to all foods based on pm, and measures are taken to prevent those contained in excess of this from being distributed as foods.

[0014] Since shellfish poison causes food poisoning by ingesting a small amount of a mouse unit orally, it is a notification from the Ministry of Health and Fisheries and the Fisheries Agency that the shellfish, shelled meat, and processed products may be distributed in the distribution of scallops. Regardless of what is contained, more than 4 mouse units of paralytic shellfish poison edible portion and 0.05 mouse unit of fat-soluble shellfish poisonous portion are regulated not to be distributed as food, and all processed products are midgut glands. Are instructed to remove and ship. Paralytic shellfish poison, which appears in the water-soluble zone among shellfish poisons, is toxic by heat sterilization at 122 ° C for 22 minutes in ordinary ordinary Japanese canned food production.
% Of the fat disappeared and almost no toxicity was found in the juice, and the fat-soluble shellfish toxins appearing in the fat-soluble section were
It is reported that it is a heat-stable poison that is soluble in fat but insoluble in water, and that it does not disappear when cooked normally. In order to eliminate and remove shellfish poison, heat sterilization at the temperature and time necessary for disappearance and removal of oil and fat were required, and the fat-soluble shellfish poison in the protein digestive fluid from which oil and fat was removed was 0.025 mouse units or less.

The processing of scallops is mainly for the purpose of utilizing scallops, and depending on the product purpose, fresh and soft-boiled internal organs are by-produced. Fresh and soft-boiled ones have a strong self-digestion ability and are easily attacked by various bacteria, resulting in rapid protein denaturation and decay. Fresh internal organs are mechanically thoroughly washed to remove dirt and foreign matter such as sand and mud and shells attached with slime, and after sufficient water exposure, they are sterilized by steaming. Also, the semi-matured internal organs are steamed and heat-exposed to heat to prevent protein denaturation. As for scallops, damaged mussels are also generated from fishing methods, and a large amount of sand and mud pieces are held in the internal organs. Foreign matter such as dirt and sand and mud pieces that adhere to the viscera such as the midgut glands along with viscous slime has a strainer-like structure that has a sand reservoir in the casing as a primary cleaning and is equipped with blades for feeding raw materials. Using a washing machine with a built-in sieve, the material is passed through it with water washing in 7 to 8 minutes to remove dirt and foreign substances. Using a washing machine with a sand trap in the casing for secondary cleaning and a lattice-like structure of an endless track conveyor equipped with a vibration function, activate the vibration function, and compress with water washing from the back side of the conveyor on which the material is placed. Air is fed, and the material is passed through in water for about 8 to 10 minutes while operating so that dirt and foreign substances are removed.

The present invention is a boiled viscera obtained by steaming raw viscera produced as a by-product of scallop processing, a mantle separated from the boiled gut, a mantle of a part other than the midgut gland, gills, sperm Biochemistry using broth obtained by boiling a suitable amount of raw internal organs into the ovary, broth obtained in the most steaming process of raw oysters, second cooked broth obtained by ripening scallops, or water. The cadmium content of the extract of the protein digestion solution that recovers the protein by converting it to the amino acid state by the conventional fermentation operation is less than the content allowed for the disposal of food, feed and fertilizer, and shellfish poison is hardly detected. In the method for producing seafood extract, it is essential to wash and bleach materials, heat sterilize by steaming, produce fermented digestion products under aerobic conditions, heat digestion products, three-phase separation, concentration, static sedimentation separation. It is a processing condition.

The dirt, sand and mud attached to the slime, and the foreign matter of the shell pieces were removed. In this step, almost all dirt and foreign substances attached together with slime can be removed. 2nd step (secondary cleaning) The casing has a sand trap, and the washing machine with a built-in conveyor has a lattice-like endless track. The air was sent and the material was passed through it in about 10 minutes while operating so that it could dance in water, and sand mud and shell fragments were removed. In this step, a cleaning material that was more cleaned could be obtained. Third step (water exposure) The cleaning material was placed in a bleaching tank and exposed to running water for 2 hours or more. This step is a treatment for eluting and transferring fine dirt, water-soluble protein, organic bound and free cadmium to exposed water. Fourth step (steaming) The material that has been washed and exposed to water has a built-in net conveyor with an endless track, and is passed through a steaming pot with a structure capable of collecting broth in a temperature of 122 ° C or higher for about 25 minutes. I was able to get the offal and the broth. This step is a process for eliminating bacteria and paralytic shellfish toxins and stabilizing the binding form of cadmium with the protein that organically binds, and obtains about 60% or more boiled liquid and 40% or less boiled viscera. be able to. Fifth step (water exposure of boiled boiled offal) The boiled boiled offal was stored in a bleaching tank and heat-treated for 2 hours or more with running water to remove heat. In this step, heat of the material is removed to prevent protein denaturation, and water-soluble proteins and organic-bonded and free cadmium are transferred to the exposed water.

Step 6 (Material Crushing) The boiled visceral organs that had been heat-exposed to water were crushed with a meat chopper. This step is a treatment for facilitating the fermentation operation. 7th step (fermentation digestion) The fermented raw material made by mixing the broth 1 obtained in the 4th step with the crushed boiled viscera 1 stored in a constant temperature fermentation tank,

%, The digest was produced by continuous aerobic stirring fermentation at 48 to 50 ° C. for 6 hours or more. This step is a treatment for converting the protein into an amino acid substance without impairing the binding form in which cadmium organically bonds with the protein. Eighth step (heating of digestion product) The fermentation digestion product was heated to 95 ° C or higher. This step is a treatment for deactivating the enzyme by heating the digest and eliminating the viscosity to facilitate three-phase separation. Ninth step (three-phase separation) The heated fermentation digest was separated into three phases by a three-phase separator.
This step is a process for separating the solid content of the difficult-to-decompose substance, the extract of the protein digestive juice of the squeezed juice, and the fat and oil, and the fat-soluble shellfish poison is also removed by the separation of the fat and oil. The cadmium content of the extract obtained by this treatment is 0.94 ppm, and the juice residue is 3
At 0 ppm, the fat-soluble shellfish toxin was below 0.025 mouse units. Step 10 (concentration) The extract of the protein digestion solution obtained by the three-phase separation was concentrated to Brix 50. This step is a process for volume reduction and preservation of the extract. The cadmium content of the extract obtained by this treatment was 7.4 ppm. Eleventh step (static sedimentation) The extract concentrated to Brix 50 was statically sedimented. This step is a treatment for precipitating cadmium and an organically bound protein together with the hardly decomposable substance to be precipitated, and further reducing the cadmium content of the extract. The cadmium content of the extract obtained by this treatment was 2.1 ppm.
