How long can cooked food be kept in the refrigerator, and how long does cooked food generally last i

The emergence of the refrigerator greatly solves the problem of food preservation, because the temperature of the refrigerator is low, and it can also be adjusted, so that the temperature inside the refrigerator can be adjusted according to the preservation needs of food. With the improvement of living standards, most families will have refrigerators to meet their daily needs. Storing cooked food is the most commonly used function of the refrigerator, so let's take a look at how long cooked food can be frozen in the refrigerator?

I hope you can understand a little bit.

Store cooked meat for more than 4 days, eat leftover meals for 3 days, and eat fruits and vegetables for up to 1 week.

The common refrigeration temperature for food in the refrigerator is 4 to 8 °C, in which the growth rate of most bacteria slows down. However, some bacteria are cold-loving, such as Yersinia and Listeria can grow and multiply rapidly at this temperature, and if you eat food infected with these bacteria, it will cause intestinal diseases.

In the freezer of the refrigerator, the temperature is generally about minus 18, and at this temperature, bacteria will generally be inhibited or killed, so the food stored in it has a better preservation effect. However, freezing does not mean that it can completely kill bacteria, and there are still some bacteria with strong frost resistance that will survive.

So, from another point of view, if the refrigerator is not disinfected frequently, it will become a "breeding ground" for some bacteria.

Extended information on how long cooked food can be kept in the refrigerator:

Food refrigeration is not only beneficial to maintain the appearance, flavor and nutritional value of food, but also helps to reduce the loss caused by pests, parasites and rodent infestations, and improves its safety.

Now, with the continuous development of food processing technology, cooling and refrigeration technology is also used in the processing process, thus improving the quality of food processing. The reaction rate of certain chemicals and enzymes in the food production process, as well as the metabolism and growth rate of the required food microorganisms, such as cheese ripening, beef tenderization, meat curing, beverage and wine aging, etc., are also often controlled by refrigeration technology.

Cooked food in the refrigerator may look fresh on the outside, but it is likely to have gone bad. After the cooked food is ready, the temperature drops to room temperature and bacteria are easy to breed, and the number of bacteria is even more alarming when the cooked food is stored for more than three days, and if you continue to eat, it is easy to cause food poisoning. Because the temperature of the refrigerator is generally kept at minus 2 6, this temperature does not destroy bacteria.

Some Enterobacteria, Enteritidis bacilli, etc., are very cold-tolerant.

At the same time, the raw food stored in the refrigerator may be contaminated with various bacteria, and it is likely to be cross-infected with cooked food, which will greatly increase the probability of bacterial infection of cooked food, so try not to put raw and cooked food together.

Note: Fresh fruits and vegetables, except for juicy ones such as cucumbers and grapes, should be wrapped in plastic wrap before putting them in the refrigerator; When storing leftover meals, attention should be paid to separating raw and cooked meals to avoid cross-contamination, and there should be a gap between them and the refrigerator wall to facilitate air circulation. Cooked food in the refrigerator should be eaten after heat treatment, because high temperature heating is the best way to sterilize.

Of course, the best way to keep it fresh is not to buy too many things at one time, so as not to cause unnecessary waste, and every time you make food, arrange it reasonably according to the number of people to reduce the chance of leftovers.

If you put it in the refrigerator, it will be stored for up to 5 days, because the nutrients of cooked food will be slowly lost, and the taste will be lighter, and frozen food is not good for physical and mental health for a long time. It's best not to leave it for too long and be reluctant to eat it, and eat it on the same day or the next day. Nothing was wasted.

If you refrigerate, it is best to eat it the next day, if it takes longer, put it in the freezer, although the time can be put for a longer period of months, but it is not suitable to be left for a long time, and cooked food should be eaten as soon as possible.

Extended Information:1Cooked food should be cooled before entering the refrigerator. If the food is not sufficiently cooled and suddenly enters a low-temperature environment, the food center is prone to qualitative changes. The heat from the food causes water vapor to condense, which can encourage mold growth and lead to mold decogeneration throughout the refrigerator.

2.Cooked food taken out of the refrigerator must be returned to the pan. The temperature inside the refrigerator can only inhibit the growth of microorganisms, but not completely kill them. If it is not heated thoroughly before eating, it may cause illness after eating.

3.Food should not be re-frozen after thawing. Repeated freezing can lead to the loss of food tissue and nutrients.

Cooked food is kept inside the refrigerator and needs to be determined according to the time when the cooked food has spoiled. Cooked food that is easy to spoil should generally not exceed 12 hours, and even if it is heated before eating, it will affect the individual's body. And cooked food that is not easy to spoil, do not exceed 24 hours.

It is best not to refrigerate it in the refrigerator (refrigerator room) for more than three days, and the breeding conditions of bacteria in different cooked foods are not the same, so when you take it out to eat, you must check whether the cooked food has a peculiar smell, if there is a peculiar smell, then resolutely do not eat it, even if there is no peculiar smell, you must reheat it to a boiling state before eating cooked food, you must know that high-temperature heating is a very simple and effective method of home sterilization.

Don't use your refrigerator as a universal storage box.
