TECHNICAL FIELD The present invention relates to a method for treating freshwater fish such as silverfish, forsythia, and grass carp. "Prior art and its problems" In general, many freshwater fish species have a so-called "mud-smelling" or "muddy-smelling" odor, and in particular, forsythia and grass carp have a strong odor, so consumers do not like them. It is shunned. Therefore, despite being a highly reproductive and economical fish species, demand has not increased. In response, many seafood processing companies have attempted various treatments to deodorize freshwater fish that have these odors, but have not yet achieved satisfactory results. "Object of the Invention" An object of the present invention is to provide an effective treatment method for deodorizing freshwater fish. ``Structure of the Invention'' That is, the present invention removes the inedible parts of freshwater fish such as silverfish, forsythia, grass carp, etc., then immerses them in a solution containing milk protein components, and then takes them out of the solution and heats them at a high temperature and pressure of 105°C or higher. This is a method of processing freshwater fish that is characterized by: In the processing method of the present invention, the inedible parts of the freshwater fish are first removed; in this case, the inedible parts include, for example, the head and internal organs of the fish;
Bones and skin may also be included. Further, bones, skin, etc. may be removed in a later step. In addition, in the present invention, the milk protein component is
For example, milk, skim milk, condensed milk, and other substances containing milk proteins. This milk protein component is dissolved in water, and freshwater fish from which inedible parts have been removed as described above are immersed in the solution. In this case, the content of the milk protein component in the solution is suitably 2 to 30% by weight, and the immersion time is suitably 2 to 20 hours.
In addition to milk protein components, this solution contains
Seasonings, spices and other ingredients may be added. Furthermore, in the present invention, high-pressure, high-temperature heating refers to treatment at a temperature of 105°C or higher using a pressure-resistant heater, preferably at 110 to 130°C for 10 to 30 minutes. This high-pressure, high-temperature heating may be performed directly after taking the freshwater fish out of the above solution, or may be performed by immersing it in water or an aqueous solution. In this case, the aqueous solution may be water to which spices or water-soluble calcium salts have been added. Freshwater fish treated in this way has no odor or taste such as so-called "muddy taste" or "muddy taste".
It is extremely delicious. Although this deodorizing mechanism is not clear, it is thought to be as follows. For example, in the production of sterilized milk, it is known that when milk is heat-treated at high temperature and pressure, milk protein components are denatured and browned, and a burnt odor is produced. (See “Food Processing Methods,” supervised by Junichi Ozaki, Asakura Shoten, p. 401). It is thought that when the milk protein component is denatured at high temperature and high pressure in this way, it reacts with the odor components of fish and is masked, resulting in an excellent deodorizing effect. Additionally, high-pressure, high-temperature heating softens the fine bones found in freshwater fish, making them edible whole. From a different perspective, it is thought that the softening effect of bones (including small bones) due to high-pressure, high-temperature heating is one of the factors that promotes the effect of milk protein components on the odor and flavor components of bone and meat. "Embodiments of the Invention" Example 1 The head and internal organs of 10 kg of forsythia were removed, washed with water for pretreatment, and then immersed in a mixture of 4 kg of milk and 5 kg of water for 24 hours. Thereafter, the forengyo was taken out and heated at 120°C for 20 minutes (sample). As control samples, 10 kg of forsythia was soaked in plain water for 24 hours, the head and internal organs were removed in the same manner as above, and then taken out and heated at 120°C for 20 minutes (sample), and the head was removed in the same manner as above. A specimen (sample) was prepared by immersing 10 kg of Forsythia with its internal organs removed in a mixture of 4 kg of milk and 5 kg of water for 24 hours, then taking it out and heating it at 100°C for 40 minutes. Furthermore, after soaking 10 kg of forengyo in water for 24 hours with the head and internal organs removed in the same manner as above,
A sample was prepared by boiling it in water for 40 minutes at ℃. Each sample treated in this way was evaluated for residual odor and taste by a panel of six people. The results are shown in the table below.

[Table] From the above table, it is recognized that the treatment method of the present invention is excellent in deodorizing and taste effects. Example 2 Cut 10kg of sougyo into three pieces, and add the fillet portion to 1kg of condensed milk, 1kg of salted mirin, and 0.01kg of koshiyo.
After being immersed for 15 hours in a mixed aqueous solution consisting of 7 kg of clove powder and water for 15 hours, it was taken out, immersed in a separately prepared aqueous dispersion of 0.1% by weight of clove powder, and heated in a retort at 115° C. for 20 minutes. Fish bodies treated in this way had almost no characteristic fishy odor, although a slight clove odor was detected. Example 3 5 kg of silver fillet was immersed in a liquid mixture consisting of 0.5 kg of skimmed milk powder, 2 kg of mirin, 0.2 kg of salt, 0.3 kg of seasoning (HAP), and 10 kg of water, which was taken out and divided into two samples. Then, the sample was heated at 115°C for 30 minutes with the water drained, and the sample contained 0.1% by weight of estragon, 0.1% by weight of calcium chloride,
It was placed in an aqueous solution containing 1% by weight of mirin and heated in a retort under the same conditions. As a result, almost no fish odor could be detected in either sample, but the sample had a better deodorizing effect. "Effects of the Invention" As explained above, according to the present invention, almost all of the fishy odor of freshwater fish can be removed, and fine bones can be softened so that the bones can be eaten together. Therefore, it is possible to effectively utilize economical freshwater fish with high reproductive capacity.
