The best way to preserve fresh fish is to store it in a refrigerator or freezer, but some ice cubes need to be added during transportation, which will help transport the fish.

Therefore, it is recommended that you understand the preservation methods of frozen fish, especially those who cook seafood.

Chilled food refers to products whose temperature is reduced to around 0°C within a short period of time after the catch is brought ashore, and which are maintained within this temperature range during transportation and storage. At this time, the product is at the critical point of freezing, the meat remains soft, and the low temperature prevents bacteria from multiplying. The taste and nutrition are retained to the greatest extent, making it more delicious than frozen products.

This freezing method usually involves covering the seafood with layers of crushed ice to preserve its freshness. When we go to the supermarket to buy fish, we often see seafood displayed on piles of ice, which are usually chilled. The chilled preservation method is suitable for seafood with a short transportation distance. Chilled fish has been out of the water for a short time, and citizens tend to think that chilled fish is fresher. The market price is higher than that of frozen fish.
