Fish is a very common type of seafood. The nutrition in fish is very rich. Fish tastes tender and tender, especially suitable for the elderly and children. Regular consumption of fish has many health benefits. Although fish has high nutritional value , but the preservation method of fish is something most people care about.
The seafood freezer is a cold storage for freezing seafood or seafood. Generally, the temperature is generally set at -18°C~-23°C. “There are also special circumstances that require special environmental settings. For example, the temperature of some deep-sea fish, such as tuna cold storage, may reach -40°C~-60°C.
1-Category specification storage
Compared with fruits and vegetables, aquatic fish has some less unacceptable tastes. Therefore, as a cold storage management operator, you should not be greedy for convenience. Because of the various microorganisms and bacteria carried by them, they will cause mutual infection.
2. Quality inspection before storage
Carefully check the aquatic products. When purchasing in large quantities, there will be some rotten fish mixed in them. Before entering the cold storage, the products with deterioration problems must be picked out to avoid pollution and damage to other products.
3. Pre-cooling and anti-odor
Aquatic fish should be fully pre-cooled before being frozen in storage, which can effectively reduce the special smell of frozen fish, so that the fish will not have a great smell when entering the cold storage, so as to better achieve the effect of low-temperature storage .
4. Strictly control the temperature of the cold storage
During the storage process, the temperature of the cold storage does not meet the requirements, and the center temperature of the frozen product does not reach the expected temperature, which will lead to spoilage of aquatic products. In this case, the temperature of the storage room should be adjusted in time, or the corresponding transfer should be done.
5. Regularly ventilate the frozen fish cold storage
Frozen fish cold storage is poorly ventilated for a long time, and the temperature and humidity are too high, which can easily cause bacteria to multiply rapidly, resulting in deterioration and odor of frozen fish. At the same time, the leakage of refrigerant (ammonia) in the refrigeration pipeline of the cold storage corrodes into the food, which not only causes food odor, but also causes various food safety problems.
(Precautions)Fish contain a large amount of unsaturated fatty acids, which are easily oxidized, especially fatty fish, whose stability is extremely low at low temperatures. Therefore, in addition to ice coats after freezing, frozen fish should also be regularly sprayed with low-temperature water on the outer surface of the stack during the cold storage process to thicken the ice coats.
