Hot food just cooked can't be put in the refrigerator for the following reasons. Some people think that hot food can't be put in the refrigerator, but others think that it can be put in, because cooked food must be thoroughly cooled in the refrigerator, so that it will deteriorate when it enters the low-temperature environment after being fully cooled, so the food will condense with hot air, leading to the growth of bacteria, which will lead to the whole refrigerator becoming a breeding ground for bacteria. Therefore, the food should be cooled and stored in the refrigerator. Others think that hot dishes can't be put into the refrigerator, because in a high temperature environment, bacteria will grow very fast, and when they are cooled, they will have a long chance, so when they are put into the refrigerator after being cooled, their bacteria will become a lot, which will be unsafe. When we put hot dishes in the refrigerator, the refrigerator will lose energy, even exceeding its capacity, causing the temperature of the refrigerator to rise and the food in the refrigerator to go bad. There are also containers that will burst. If hot food is put in, it may lead to this phenomenon. No matter what food is left at room temperature for a long time, bacteria will become very abundant and unsafe. Therefore, our general food should be put in the refrigerator for two hours, and it should not exceed one hour in summer. When the dish is hot, put the plastic wrap on it, package it and put it in the refrigerator for cold storage, so as to avoid water vapor from frosting, so as to prevent bacteria from entering it, and also to prevent odor. If the dish is hot, you can cool it with ice water, and then put it in the refrigerator, so as to cool it down and prevent bacteria from entering it quickly. Don't wait for it to cool down. Let it grow some bacteria, which will do harm to our health when we eat it. If the food is too hot, it can't be cooled quickly, so we should pack it into several servings in advance and put it in the refrigerator so that it won't go bad. We can't put too much food in the refrigerator when putting vegetables. If it is too crowded, its function will be reduced, and the cooling effect will not go bad easily in summer. The meat in the refrigerator should be heated, boiled and sterilized, so that it will be good for our health.
