Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for producing raw materials for feed, food, medicine, etc. by extracting amino acids, proteins, etc. contained in fish bodies.

(Prior Art) Conventionally, the main methods of processing and processing of caught fish include salting, seasoning, canning, bottling, and edible processing such as dried bonito flakes.

On the other hand, methods that actively try to extract and utilize organic components such as amino acids and proteins that are abundantly contained in fish bodies include the use of fish solubles as feed, cod, macro, shark, etc. Cod liver oil and vitamin oil collected from the livers of sharks, and insulin collected from the pancreas of sharks are only used as raw materials for pharmaceuticals, and the number of such products is extremely small.

(Problem to be solved by the invention) This is mainly due to the fact that the proportion of the head, bones, etc. contained in the fish body is extremely large compared to the fish meat, internal organs, etc., and even in fish meat, internal organs, etc., amino acids are In order to collect proteins, etc., unnecessary components must be removed, and this process is extremely difficult.

Therefore, the object of this invention is to propose a method for efficiently increasing amino acids, proteins, etc. from fish bodies and using them as raw materials for feeds, foods, medicines, etc.

(Means for Solving the Problems) In view of the above-mentioned circumstances, the present invention has been developed as a result of intensive research, and has been developed based on one or two of the following: the whole fish body or a part thereof, or the residue, internal organs, broth, and stick water obtained in the fish processing process. Seeds and above are used as raw materials, of which the whole body or part of the fish, or the residue and internal organs obtained in the fish processing process are crushed as necessary.
In addition, the broth and stick water are sent as they are to a digestion tank, where they are digested, and the digested matter is further separated into solid and liquid, and then transferred to an ultrafiltration machine to be filtered to produce raw materials for feed, food, medicine, etc. This is what we propose.

Here, examples of fish used as raw materials include bonito, tuna, and sardines.

In addition, the raw materials include raw whole fish including the head, bones, etc. or canned fish, fresh residues or internal organs from processed bonito flakes, food processing, etc., the broth produced from the process of producing fishmeal, and Stick water etc. obtained by removing oil from the broth can be used.

These raw materials are subjected to pulverization such as coarse crushing or pulverization depending on the type of raw materials, but the pulverizing step can be omitted when broth, stick water, etc. are used as raw materials. Another head,
When the raw material is a fish body containing bones, etc., it is necessary to perform either coarse crushing or crushing depending on the size of the raw material, but when using only internal organs as the raw material, only coarse crushing may be sufficient.

In addition, in the digestion step, one or more types of proteolytic enzymes, lipolytic enzymes, etc. are added to the digestion tank to perform digestion. Examples of the digestive enzyme used here include bacterial proteolytic enzymes such as Neovitalase Super (trade name, manufactured by Noriwa Koso Co., Ltd.). According to this enzyme, gelatin and proteins in fish meat are rapidly decomposed and liquefied.
Separation operation in an ultrafilter can be easily performed.

Note that when the raw material contains a large amount of digestive enzymes, for example, fish internal organs, there is no need to add digestive enzymes from the outside.

Digestion in a digestion tank is carried out, for example, at approximately 50 to 60°C.
Digestion is carried out by raising the temperature to 30 minutes to 3 hours, preferably 1 hour to -2 hours, and after digestion, the temperature
The temperature is raised to C to stop digestion and deactivate the digested substances.

The digested material is separated into solid and liquid and transferred to an ultrafilter. Solid-liquid separation may be carried out using a vibrating sieve, centrifuge, oil separator, etc.Depending on the digestion situation, it may not be necessary to perform all of these solid-liquid separations, and one or more of these may be used. In some cases, a combination may be sufficient. Note that a salt removal step may be inserted before or after the ultrafilter in order to adjust the salt concentration of the final product.

In the ultrafilter, the digested material is passed through an ultrafiltration membrane to remove oil and the like contained therein.

The smallpox filtrate taken out from the ultrafilter can be used as feed,
It can be used as a raw material for foods, medicines, etc.
Further, a concentrated extract obtained by transferring to the concentration step and a dry product obtained by transferring to the concentration/drying step may be used as these raw materials.

In addition, if the discharged liquid foams considerably during the step of taking it out from the ultrafilter, an antifoaming agent may be added to the filtrate.

(Example) Examples of this invention will be shown below.

Raw materials include whole fish, canned fish, fresh residues processed through AM processing, food processing, etc., or their internal organs.

In the crushing process, a crusher 3 is provided via a crusher 1 and a pump 2, and the raw material is first crushed by the crusher 1 if necessary.Next, water is added to the crushed raw material. The raw material is sent to a crusher 3 using a pump 2, and is further crushed so that the active ingredients of the raw material are transferred to the liquid.

The raw material pulverized in the pulverization 413 is fed to the digestion tank 5 by the pump 4 with water added thereto as required, and is digested. In the digestion tank 5, depending on the raw material, if necessary, 20% to 20 oz of water is added and digestive enzymes are added for digestion, or the raw material itself undergoes self-digestion to decompose gelatin, etc., and prepare it for subsequent processing. The separation of active ingredients can be effectively promoted.

Incidentally, the broth produced in the process of producing fish meal or the stick water obtained by removing the oil from the broth can also be used as a stock solution by enzymatically decomposing it in the same way.

In addition, the digestion in the digestion tank 5 is carried out, for example, by approximately 50 to 50% of the raw material.
Raise the temperature to 00C for 730 minutes to 3 hours, preferably 1 hour to
Digested by holding for 2 hours.

After digestion, the temperature is raised to 70-95°C to deactivate the digestive enzymes and stop the digestion.

The raw material digested in the digestion tank 5 is transferred to a solid-liquid separation process. In this embodiment, the solid-liquid separation step is composed of a vibrating sieve 6, a centrifuge 7, an oil separator 8, a strainer 9, and a digestion tank 5.
The enzymatically decomposed or self-digested liquid passes through a vibrating sieve 6, a centrifugal separator 7, an oil separator 8, and a strainer 9 to separate and remove solids.

The stock solution from which the solid content has been removed is stored in the stock solution tank 10a.

10b. Raw solution tank 10a
, 10b is guided to an ultrafilter 11 equipped with an ultrafiltration IQ inside after undergoing a salt removal process as required.

Ultrafiltration 41311 separates high-molecular components such as oil and high-molecular proteins of the stock solution from low-molecular components such as amino acids and low-molecular proteins. Furthermore, the stock solution is passed through ultrafilter 1.
1 and stock solution tank 1. By circulating between Oa and ]Ob, a liquid rich in components such as amino acids and low-molecular proteins can be obtained.

Since the liquid thus produced is rich in amino acids, low-molecular proteins, etc., it can be used as is as raw material for feed, pharmaceuticals, foods, etc.; however, these concentrated liquids,
Alternatively, concentrated extracts obtained by vacuum concentrating these liquids at low temperatures, or even dried products obtained by drying the concentrated extracts, may be used as raw materials for feeds, medicines, foods, and the like.

Therefore, the filtrate rich in amino acids and low-molecular proteins that has passed through the ultrafilter 11 is sucked by the pump 12 and stored in the filtrate tank 14, and the liquid stored in the filtrate tank 14 is
They are sequentially transferred to a vacuum concentration step by a pump 15, where they are vacuum concentrated at a low temperature.

The vacuum concentration process consists of a concentrator main body 16, a vapor condenser 17, and a vacuum device 18, and the liquid transferred by the pump 15 as described above is heated by the heater part 16a of the line device main body 16 and concentrated. 16b.

The inside of the BIIrfJ section 16b is maintained in a vacuum state by a vacuum device 2118, so that the filtrate is separated from water and concentrated.

In the concentrator main body 16, for example, the inside of the concentrator 16b has a vacuum degree of fioOTorr ~50 Torr and a temperature of about 50 Torr! ] (1~
Low-temperature vacuum concentration is carried out under conditions such that the active ingredients on the sa'c level do not decompose, and the water content is reduced to 60 to 20%.

The mist entrained by the water separated in the concentration section 16b is sent to the vapor condenser 17, where it is separated by the mist separator 19 and returned to the concentration device main body 16.

Furthermore, the vapor condenser 17 is cooled to condense water, and the condensed liquid is transferred to a wastewater treatment process.

In addition, the e-condensed extract obtained from the concentrator body 16 is sequentially sent to a product tank 21 by a pump 20, and in the two-product tank 21, the concentrated extract is taken out as needed to become a product. 'a-condensed extract is concentrated in a low-temperature vacuum, so amino acids and low-molecular proteins do not decompose.
Therefore, it is possible to obtain feed, food, and pharmaceutical raw materials with higher concentrations.

Furthermore, in this example, a part of the concentrated extract is transferred to a drying device 22 such as a drum dryer, a spray dryer, or a vacuum dryer, where it is dried under conditions that do not decompose amino acids, proteins, etc. Dried products are stored in product tank 2.
3, and then taken out as needed and used as raw materials for feed, food, and medicine.

Next, after digesting and decomposing the fish broth as in this invention, the decomposition liquid (undiluted solution) is passed through an ultrafiltration machine, and the content of each amino acid in the undiluted solution and the filtrate and the permeability of each amino acid are determined. Also, the undigested liquid, i.e., the undecomposed liquid (undiluted solution), is the undiluted solution obtained by passing it through an ultrafilter, i! ! The content of each amino acid in the permeate and the permeability of each amino acid are shown in Table 1 below.

Table 1 Total amino acids A This was larger than when the undigested product was passed through the ultrafilter, and the processing speed was about three times higher than when it was passed through the ultrafilter without being digested.

In addition, after digesting fish internal organs, the digestive juice (undiluted solution)
The amino acid content in the stock solution and filtrate when passed through an ultrafilter is shown in Table 2, and the test results for the enzymatically decomposed liquid and permeated liquid of the frontal broth are shown in Table 3, both of which are the same as above. Good results were obtained.
