1. It is found that it takes a long time for the refrigerator to lower the food center temperature of a container. This process creates a comfortable growth environment for bacteria. Therefore, it is best to store hot food for a period of time and let it cool evenly. Or you can put hot food in a small container and then put it in the refrigerator-it will cool faster.
2, hot dishes in the refrigerator will destroy the cold room environment. Putting hot dishes in the refrigerator will really damage the refrigerator, but what we are talking about here is not the load of the refrigerator, but the environment of the freezer.
Psychrophilic bacteria can survive in extremely cold conditions, among which Listeria is the most common one. The optimum temperature of Listeria is 2-8 degrees. When hot food is put into the refrigerator, the overall temperature of the refrigerator will rise, which may lead to the proliferation of bacteria and increase the chances of contamination of other foods.
In addition to psychrophilic bacteria, ordinary bacteria in cold storage may also multiply because of rising temperature. Therefore, putting food in the refrigerator while it is hot is not the best way to keep healthy.
Extended data
There are three principles for storing food in the refrigerator:
① Prepackaging
If you feel that you can't finish eating, you'd better pack it in a fresh-keeping box in advance or wrap it in a fresh-keeping bag. At this time, the food contains the least bacteria.
(2) After cooling, put it in the refrigerator.
If it only needs to be placed for a short time, it does not need to be placed in the refrigerator; If it needs to be preserved for a long time, it can be put in the refrigerator when the food temperature is not too hot.
③ Disinfect the refrigerator.
Don't pile up too much food in the refrigerator, and don't store it for too long. Regular use of disinfectants can ensure the cleanliness of the refrigerator and greatly reduce the number of bacteria in the refrigerator.
