There are many kinds of food that can be bought in the supermarket, including all kinds of vegetables and meat. With the progress of science and technology, the quick-frozen food which is convenient for people's life has become very common. The quick-frozen food is easy to eat and loved by people. Usually, after people buy them, they will put them in the refrigerator, eat them at any time and take them out at any time, and keep them in the refrigerator for a long time.

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
