The present invention relates to a method for modifying the flesh quality of sporozoite-parasitic fish. In recent years, as the supply and demand situation for fishery resources has worsened, attention has been focused on the use of fish species such as Pacific hake, hake, and halibut whose fleshy parts are infested with sporozoites (Myxosporidia) as food ingredients. However, due to the action of the sporozoites that parasitize these fish species, the tissue of the flesh collected from them changes over time into a porridge-like structure (meat-like formation).
These fish species have serious deficiencies in their use as food ingredients and raw materials for processed seafood foods, as they change into a sol-like state (jelly meat). For example, when making kamaboko using the meat of Pacific hake or hake as raw material, when salt is added to the surimi, crushed, and then heated, the structure of the fish meat is rapidly destroyed, resulting in a scallion-like structure. The elastic product unique to kamaboko cannot be obtained. In order to utilize sporozoite-parasitic fish as mentioned above as food materials and raw materials for processed marine products, the present inventors have investigated the causes of deterioration in the flesh quality of fish and measures to address the problem. The present invention was made based on the knowledge that proteolysis is caused by the action of an enzyme, and that the action of the proteolytic enzyme can be suppressed in the presence of a specific compound. Therefore, an object of the present invention is to provide a method for modifying the flesh quality of sporozoite-parasitic fish so that the flesh can be advantageously used as a food material and a raw material for processed seafood foods. The present invention will be explained in detail below. A feature of the present invention is that the flesh of a sporozoite-parasitic fish is brought into contact with potassium bromate or monoiodoacetic acid without undergoing any processing such as grinding. As mentioned above, the deterioration of the flesh quality of sporozoite parasitic fish is due to
This is caused by the action of a proteolytic enzyme derived from sporozoites, and more specifically, this enzyme decomposes actomyosin, which is involved in the binding and water retention properties of fish meat during cooking. In the present invention, the substance used to deactivate the protease is an oxysaccharide or protein that functions as an oxidizing agent, particularly an SH reagent that can specifically react with the SH group in the enzyme and sequester the group. An example of the former is potassium bromate, and an example of the latter is monoiodoacetic acid. In order to bring these substances into contact with the flesh of sporozoite-parasitic fish, it is preferable to add them to the flesh in the form of a powder and mix well, or to immerse the flesh in the form of a solution. In addition, the amount of these substances used is approximately 0.08% by weight or more based on the meat to be processed (in solution form,
If the concentration is 5mM or higher), the above proteolytic enzyme inactivation effect can be achieved. Generally 5 mmol to 20
It is appropriate to immerse the meat in an aqueous solution with a millimolar concentration. Next, we will discuss the deactivation effect on proteolytic enzymes in hake meat when potassium bromate is added in varying amounts to the meat, and the physical properties of processed foods prepared from the meat thus obtained. The results of the test are shown below. Test: 0.05, 0.08 for Peruvian hake meat
Table 1 shows the results of measuring the activity of proteolytic enzymes for each of the samples to which potassium bromate was added and mixed at a ratio of 0.167% by weight. The activity of the proteolytic enzyme is determined by using casein (PH7.5) as a substrate and adding the homogenate of each of the above meats to it at 50°C.
It was measured by allowing it to act over time.

[Table] From the above table, it is understood that the activity of proteolytic enzymes contained in hake meat can be substantially inactivated by adding 0.08% by weight or more of potassium bromate to the meat. . Test Fillets prepared from hake meat were added to potassium bromate aqueous solutions of various concentrations at 5°C.
After soaking for 18 hours, the fillets were heated with steam for 30 minutes and their texture was visually determined. The results are shown in Table 3.

[Table] Prepared from dress.
From the table above, it can be seen that by immersing hake fillets in a potassium bromate aqueous solution with a concentration of 5 mmol or more, the mattiness of the tissue is greatly suppressed, and when the concentration of the aqueous solution is increased to 10 mmol or more, the mattiness is completely inhibited. It is understood that this can be prevented. Test After immersing the fallen hake in potassium bromate aqueous solutions of various concentrations for 18 hours at 5°C, surimi was prepared using a conventional method, and the ability of each surimi to form fish cake was tested. The results are shown in Table 4. Incidentally, the ability to form kamaboko was expressed by the values obtained by preparing kamaboko from each surimi using a conventional method, and measuring the gel strength and bending test for each kamaboko obtained.

[Table] Adjusted from.
From the above table, it is understood that surimi prepared from hake fillets immersed in an aqueous solution of potassium bromate with a concentration of 10 mmol or more has an excellent ability to form kamaboko. As described above, according to the present invention, the flesh of sporozoite-parasitic fish, which could not be used as a raw material for seafood processing due to sporozoite parasitism, can now be effectively used as a raw material for food processing such as fillet and surimi. It is beneficial for the utilization of marine resources. Examples are illustrated below. Example 1 10kg of fillet prepared from Pacific hake was treated with a 10mM potassium bromate solution (pH adjusted with alkali).
7.0) Soak in 10Kg at 5℃ for 18 hours. After washing it with running water, it was frozen to obtain a frozen fillet. Example 2 10 kg of fallen meat collected from hake was
50mM potassium bromate solution (pH with alkali)
(adjusted to 7.0) 10Kg at 5℃ for 18 hours. After dehydrating the surimi by soaking it three times in three times the amount of water in a conventional manner, 300 g of sugar and 12 g of polymerized phosphate were added to obtain surimi. From the surimi prepared in this manner, kamaboko with a jelly strength of 500 g and bending test AA was obtained. Example 3 10 kg of fillet prepared from Pacific hake
Immerse in 10kg of 5mM monoiodoacetic acid solution (pH adjusted to 7.0 with alkali) at 5°C for 18 hours. After washing it with running water, it was frozen to obtain a frozen fillet. Example 4 10kg of fallen meat collected from hake was mixed with 30mM monoiodoacetic acid solution (pH adjusted to 7.0 with alkali)
Soak in 10Kg at 5℃ for 18 hours. After dehydrating the surimi by soaking it three times in three times the amount of water in a conventional manner, 300 g of sugar and 12 g of polymerized phosphate were added to obtain surimi. From the surimi thus prepared, kamaboko with a jelly strength of 450 g and a bending test of AA was obtained.
