Usually, the packaging of quick-frozen food will have the requirements of food preservation environment, generally at - 18 ℃. For supermarket convenience stores, to achieve such a low-temperature preservation environment, it needs to use professional supermarket freezer equipment. Island Freezer is the commonly used quick-frozen food preservation freezer. There are two kinds of environment: cold storage and freezing. The temperature of cold storage is generally 0 ℃ ~ 8 ℃, and freezing can reach below - 18 ℃. Most household refrigerators can't reach this temperature, generally only - 10 ℃, which can't meet the storage temperature requirement of - 18 ℃ for quick-frozen food. Therefore, for quick-frozen food, you should eat it as soon as possible after opening, otherwise it is easy to deteriorate.
 
For quick-frozen food, do not store it together with other fresh food, because bacteria will spread among each other and cause food deterioration. It is better to freeze and store it separately
