Crustaceans such as shrimp and crabs tend to turn black after being caught, which significantly reduces their commercial value. Blackening occurs mainly in the head and feet of shrimp, and in the leg joints of crabs. This black discoloration is caused by the action of tyrosine in the body in the presence of oxygen, such as oxidizing enzyme tyrosinase, which ultimately produces black melanin polymers. The red color of red sea bream and other red sea bream comes from red carotenoid pigments, but these carotenoids are easily oxidized, causing their color to fade. In addition, the red color of fish meat, such as tuna meat, comes from oxymyoglobin, which also changes to brown metmyoglobin when oxidized. Some foods, such as sardines and mackerel, produce browning substances when their lipids are oxidized. In this way, discoloration of marine products is often due to oxidation caused by oxygen in the air. Of course, there are some products that are not caused by oxidation, but in order to prevent these changes in color or loss of freshness, they are generally transported or stored at low temperatures. Although freezing is the most preferable method, when distributing it in a raw state, it is often used in refrigerated trucks or packed with ice in Styrofoam boxes. In particular, at present, food is often transported in ice packs due to cost and convenience, but with this method it is difficult to prevent deterioration in freshness, especially discoloration, and an effective method is desired.

(Problems to be Solved by the Invention) As mentioned above, when marine products are distributed in a raw state, even if they are refrigerated by water cooling, etc., they are kept for only one or two days, and if more days pass, the product will discolor. . Therefore, if transportation is delayed, the value of the product will drop significantly. Of course, transportation from remote locations, which takes several days, is often impossible under the present circumstances. The present invention focuses on transportation or storage packed in ice from the viewpoint of cost and simplicity, and provides a method for suppressing deterioration in the freshness of marine products using this single transportation or storage form, and in particular, a method for preventing changes in body color. The purpose was to

(Means for Solving the Problem) When transporting or storing marine products packed in ice, containers such as styrofoam boxes and water-resistant cardboard boxes are used. At this time, to drain water from melted ice,
It is common practice to provide a hole in the bottom of the container. On the other hand, as mentioned above, discoloration of marine products is often caused by oxidation due to oxygen in the air. Therefore, in order to suppress the oxidation, it is possible to replace the oxygen in the container with another gas or deoxidize it, but in this case, air will flow in from the drainage hole mentioned above. Therefore, it becomes a hindrance. If you eliminate the holes and create a closed system, the seafood will get wet with the melted water, reducing its freshness.

Therefore, the present inventors conducted various studies on containers for transporting or storing marine products packed in ice that can drain water and prevent air from entering from outside. have found that this can be solved by covering the hole with a water-permeable material such as paper, cloth or non-woven fabric. This is because a water-permeable material allows water to pass through it, but once it gets wet, it becomes impermeable to gases such as air. When marine products were actually placed in this container with crushed ice and stored in a low-oxygen state using nitrogen replacement or an oxygen scavenger, the melted water escaped outside the container, and the low-oxygen state was maintained, maintaining the freshness of the seafood. The present inventors have discovered that the present invention is possible and have completed the present invention.

The container of the present invention is for storing marine products packed in ice in a low-oxygen condition, and when actually stored, the marine products are packed in the container with ice and gas replacement with an inert gas such as nitrogen or carbon dioxide is performed. Alternatively, seal the container in a low oxygen state by using an oxygen scavenger. Although there are no particular limitations on the method of creating a hypoxic state, a method using an oxygen absorber is preferred because it is simple. Oxygen scavengers include those whose main ingredients are iron powder and electrolytes, and those whose main ingredients are hydrozulfite, sulfite, dithionite, and ascorbate. Although any oxygen scavenger can be used, one containing iron powder and an electrolyte as the main ingredients is preferred, and the oxygen scavenger composition is used by placing it in an air-permeable packaging material. In order to further enhance the effect of the present invention, it is preferable that the oxygen concentration in the container is 0.5 to 5, and the amount of oxygen scavenger used may be adjusted accordingly.

Example Work As shown in Figure 1, drain holes (2) (one diameter) were made in the four corners of the bottom of a Styrofoam box (1) with a lid, measuring 34 mm long, 52 mm wide, and 13 mm high. Polyester non-woven fabric (3) (Gurley type air permeability 10 seconds/air 1)
00 ml) was applied to prepare a storage container. This was filled with crushed ice (4), an insole (5) was placed, and 612.5 kg of fresh sweet shrimp caught that day was placed on top of it. Furthermore, an insole (7) is placed on top of it, and a normal oxygen absorber [based on iron powder and sodium chloride] is placed on top of it.
8180 g was placed in a breathable packaging material, covered with a lid, and the whole was sealed and stored at 5°C. As a result, the oxygen concentration inside the box dropped to the 2nd level after 24 hours, and then gradually decreased to about 1st level after 4 days, making it possible to maintain a hypoxic state. Meanwhile, the melted water was removed from the system through the nonwoven fabric. After 4 days, no blackening of the head or tail of the sweet shrimp was observed, and the body color remained pink. On the other hand, the head and tail of the animals that were not treated with the oxygen absorber turned black after two days.
