Does hot food go bad when you put it in the fridge, and why does it go bad when you put it in the fr

Hot dishes should not be put in the refrigerator immediately.

Harm: 1. The food does not get the expected low temperature, so that the internal temperature of the food is suitable for the breeding and reproduction of bacteria, so that it is spoiled.

2. Affect the refrigeration operation of the refrigerator, thereby shortening the life of the refrigerator.

3. Make the refrigerator replenish the freezing and cold degree, so as to increase the power consumption.

4. In addition to increasing power consumption, the reason is that due to the low temperature in the refrigerator, the moisture contained in the hot food will evaporate sharply when it is cold, and then solidify on the inside, and a thick frost layer can be formed on the evaporator in a short time, which blocks the evaporator from the inside of the refrigerator to the outside, which affects the refrigeration effect.

5. At the same time, the temperature probe is also wrapped in the frost layer, which can not detect the temperature in the box, so that the compressor stops working, resulting in the inability to refrigerate, and the compressor can only work again after the frost layer is dissolved.

Refrigerators are available in every house, and everyone can use them, but there are some precautions that may not be known to everyone.

There are six taboos for storing and freezing food:

1.Hot food should never be put in a running refrigerator.

2.The storage of food should not be too full and too tight, and there should be a gap to facilitate the convection of cold air, reduce the load of the unit, prolong the service life, and save electricity.

3.Do not mix raw and cooked food to maintain hygiene. According to the food storage time and temperature requirements, make reasonable use of the space in the box, do not put the food directly on the surface of the evaporator, but put it in the utensil, so as not to freeze on the evaporator and inconvenient to take out.

4.Fresh fish, meat and other foods should not be put in the refrigerator without processing. Fresh fish and meat should be sealed in plastic bags and stored in the freezer. Vegetables and fruits should be wiped dry on the outer surface, put them at the bottom of the box, and store them at a temperature above zero.

5.Do not put bottled liquid beverages in the freezer to avoid freezing and cracking the bottle. It should be placed in the refrigerator or on the door stall, and it is best to store it at a temperature of about 4.

6.Refrigerators for food storage should not store chemicals at the same time.

Bananas: If the bananas are rotated below 12 to store, the bananas will turn black and rot.

Fresh lychee: If the fresh lychee is left in an environment of 0 for one day, the skin will turn black and the flesh will become flavorful.

Tomatoes: After tomatoes are frozen at low temperature, the flesh is blister-like, soft and rotten, or there are black spots on the surface, undercooked, no umami, and in severe cases, they are rancid and rotten.

Ham: If the ham is stored in the refrigerator at a low temperature, the moisture in it will freeze, the fat will precipitate, the leg meat will clump or loose, the meat will become tasteful, and it will be easy to spoil.

Chocolate: After chocolate is frozen in the refrigerator, once taken out, a layer of hoarfrost will form on its surface at room temperature, which is very easy to mold and deteriorate, and lose its original flavor.

Hot dishes in the refrigerator will not be rancid, but it will slightly increase the burden on the refrigerator and consume a little more electricity, but it is within the normal operating range of the refrigerator. To prevent bacteria from growing, the best thing to do is to keep it in the refrigerator while it is hot.

Putting it in while it's hot doesn't mean putting it in just out of the pot and it's very hot. It can be packed in a crisper or plastic bag in advance, let it sit at room temperature for a while, and put it in the refrigerator or freezer until it is not less than 60 (feeling hot but not burning).

Dietary Instructions. When the temperature of the food drops to 60, bacteria begin to grow; When the temperature drops to 30 to 40, the bacteria will be happy and multiply; Dropping to 4, most bacteria cease and go into a dormant state.

4 60 is also known as the "danger zone" for food. Prepared meals should be kept as soon as possible to cool down to below 4 to avoid bacterial blooms. The World Health Organization also recommends that food should not be stored at room temperature for more than 2 hours.

The above content reference: People's Daily Online - Meals should be kept in the refrigerator while they are hot.

The dish is a little hot, so it is not recommended to put it directly in the refrigerator.

Drying the food cold before putting it in the refrigerator is good for the maintenance of the refrigerator and other refrigerated foods in the refrigerator.

Psychrophiles are bacteria that can survive extreme cold conditions, and Listeria monocytogenes is the most common of these bacteria.

The optimum temperature for Listeria monocytogenes is 2-8 degrees. When hot food is placed in the refrigerator, the overall temperature of the refrigerator room rises, which may cause bacteria to multiply and increase the chance of contamination by other foods.

In addition to psychrophilic bacteria, common bacteria in the refrigerator room may also multiply due to the increase in temperature. Therefore, putting food in the refrigerator while it is hot is not the best solution to stay healthy.

Hot dishes will not be bad if they are placed directly in the refrigerator, but they will have the following hazards:

1. After putting hot food in the refrigerator, the temperature in the refrigerator will be raised, and the refrigerator will start to cool down, which will increase the electricity consumption.

2. After the hot food is put into the refrigerator, the compressor needs to work for a long time to reach the set temperature, which will reduce the service life of the compressor.

3. The frost layer in the refrigerator is caused by the moisture in the refrigerator, if you often put hot dishes into the refrigerator, a large amount of moisture emitted by the hot dishes will make the frost layer in the refrigerator thicker and thicker, affecting the refrigeration effect of the refrigerator.

4. Under the condition of normal use, the temperature of the refrigerator liner will be very low, all below zero, if the hot dishes with higher temperature are put into the refrigerator, the temperature of the refrigerator liner will rise, and the liner will be easy to rupture according to the principle of thermal expansion and cold contraction, and shorten the service life of the refrigerator.

Putting overheated food in the refrigerator will cause the internal temperature of the refrigerator to rise, so that the food inside cannot be kept fresh, and the food is prone to spoilage. In addition, if the hot food is placed in the refrigerator, the refrigerator will need to "work" twice as much to lower the temperature of the food, which will increase the power consumption of the refrigerator.

Hot dishes will evaporate a large amount of water vapor in the refrigerator, and the water vapor will condense into frost in the refrigerator, which will easily affect the normal operation of the refrigerator.

If you are afraid that bacteria will grow during the process of letting the food cool, you can use plastic wrap or a crisper to seal the food to prevent external bacteria from entering.

1. The inside of the refrigerator should be maintained for about 4, so that the food stored in the refrigerator can be stored for a long time. If you put hot things directly into the refrigerator, the temperature in the refrigerator will rise, and the condition that the inside of the refrigerator should be maintained about 4 is not reached, and the food stored in the refrigerator is easy to spoil.

2. When hot things are put into the refrigerator, some heat is brought into the refrigerator, and the refrigerator needs to work to lower the temperature, which requires electricity consumption and also increases the burden of the refrigerator, which will reduce the lifespan.

3. Due to the low temperature in the refrigerator, when the hot food is cold, the moisture contained in it will evaporate sharply and then solidify on the internal evaporator, and a thick frost layer can be formed on the evaporator in a short time, blocking the evaporator from transferring the heat in the refrigerator to the outside.

4.Do not neglect to clean the door seal, dilute the bleach with 10 times the water, moisten it with a toothbrush, and finally rinse the bleach with water. The rubber strip is dirty and easy to age, which will affect the sealing of the refrigerator and increase power consumption.

5.Check vibration, noise, and compressor temperature. When touching the compressor shell during operation, there should be no obvious vibration, and the sound of the compressor starting should not be heard during the day.

6.Pay attention to check whether there are cracks in the power cord to prevent leakage.

7.Wash and dry the inside and outside of the refrigerator with warm water or mild detergent, and leave the refrigerator door open to air and dry for a day.

The refrigerator should not be overfilled, and there should be room for cold air to penetrate the entire inventory. In addition, the refrigerator should be disinfected regularly. Wipe down with dilute bleach or potassium permanganate water every 3 to 4 weeks, and wash the refrigerator regularly, including the plates, especially the filter, which is often a place for dirt and germs to accumulate.

Regular and proper maintenance can extend the life of your refrigerator. Always unplug your refrigerator before servicing it.

1. Frequently clean the dust on the back or bottom of the refrigerator condenser and compressor. Dust can be removed using a vacuum cleaner or brush. Be careful not to use a damp cloth to wipe dust off the refrigerator and compressor.

2. When the refrigerator is out of use for a long time, the power should be cut off first, all the food in the box should be taken out, the inside and outside of the box should be cleaned up, and the door of the box should be opened for several days to fully dry the box and dissipate the odor in the refrigerator.

3. Check the drain pipe. If the drain is clogged, the water will leak into the refrigerator. Poke the drain pipe with wire to remove the build-up on the drain.

Hello, I'm glad to answer for you, hot dishes in the refrigerator will not be poisoned, but the food does not get the expected low temperature may make the internal temperature of the food suitable for the growth and reproduction of bacteria, so that it will spoil. Secondly, it may also affect the refrigeration operation of the refrigerator, thereby shortening the life of the refrigerator. The refrigerator is replenished with the freezing degree and thus the power consumption is increased.

In addition to increasing power consumption, the reason is that due to the low temperature in the refrigerator, the moisture contained in the hot food will evaporate sharply when it is cold, and then solidify on the inside, and a thick frost layer can be formed on the evaporator in a short time, blocking the evaporator from the inside of the refrigerator to the outside, affecting the refrigeration effect.

Putting hot food directly in the refrigerator does increase the burden on the operation of the refrigerator and consume more electricity. However, if you wait for it to cool before putting it in the refrigerator, it will also breed some bacteria, resulting in shorter storage time and worse taste of the food.

However, these issues are actually relative.

If you eat all the leftovers within a day or two, in fact, the number of bacteria growing during the cooling period will not exceed the normal range, so there is no need to worry about the safety of eating.

On the other hand, the refrigeration efficiency of the refrigerator is now greatly improved than before, as long as you don't put a lot of hot things into the refrigerator at one time, it will not have much impact on the refrigeration of the refrigerator, and it can still run smoothly.

And the extra amount of electricity, even if you do it every day, will spend an extra dollar a month on the electricity bill, which is simply negligible, and you don't need to care too much.

Therefore, if you need to store it for a longer time, it is recommended to put the hot dishes directly in it, which is completely fine. If you can eat it quickly, you can also let it cool before putting it in the refrigerator, and you can cover it with plastic wrap first to prevent the invasion of external bacteria and cause more problems.

In addition, there are some things that you habitually put in the refrigerator that are not suitable for the refrigerator environment.

Chocolate and honey, for example, should not be put in the refrigerator from a flavor point of view.

If you look closely at the chocolate in the refrigerator, you will often see some white build-up on the surface, which is the fat crystals that have precipitated from the chocolate due to the low temperature. Long-term storage will cause the flavor of the chocolate to change, and it will become less and less delicious.

In the same way with honey, low temperature will precipitate glucose in honey, and if you take it out of the refrigerator and eat it again, it will not have the original sweetness, which will have a great impact on the taste.

However, sometimes, putting them in the refrigerator is also a helpless move, and the taste is almost a little worse, at least the refrigerator can protect them from spoiling, and that's enough.

Hot dishes should not be placed in the refrigerator. Hot dishes bring a lot of heat, and putting them directly in the refrigerator requires the refrigerator to start refrigeration immediately, which brings the consumption of pad power. If you need to bring a boxed lunch, you can seal it with plastic wrap and put it in the refrigerator if it is slightly hot, so that it is better to protect and have fewer bacteria.

Do not put it in the refrigerator when it is hot.

1. The temperature of the hot dish will be very high, and the built-in temperature of the refrigerator must be reduced, after putting the hot food into the refrigerator, the temperature in the refrigerator will be increased, and the temperature in the refrigerator will start to cool down, and this cooling process will increase the electricity consumption, which will increase your electricity bill.

2. Putting hot dishes in the refrigerator will also increase the workload of the refrigerator compressor. After the hot food is put in the refrigerator, the compressor needs to work for a long time to reach the set temperature, which will reduce the life of the compressor.

3. There are many frost layers in the refrigerator, which are caused by the moisture in the refrigerator, if you often put hot dishes into the refrigerator, and the hot dishes will emit a lot of moisture, which will make the frost layer in the refrigerator thicker and thicker.

Hot dishes cannot be placed directly in the refrigerator, which will cause a great burden on the refrigerator, and the inside of the refrigerator is easy to frost and easy to break, and it also consumes electricity. Therefore, it is believed that the hot dishes should be cooled before being stored in the refrigerator.

Hot dishes should be put directly in the refrigerator, especially in the summer high temperature environment, the bacteria breed and multiply too quickly, and the process of waiting for it to cool provides time and environment for bacteria to grow, which will be more unsafe.

Only by quickly cooling the temperature of the food to below 5 degrees (generally the temperature of the refrigerator is about 4) can it help inhibit the growth and reproduction of bacteria and ensure the safety of food for consumption.

Therefore, food that needs to be refrigerated should not be stored at room temperature for more than 2 hours, and in summer, when the outdoor temperature is above 32, it should not be stored for more than 1 hour.

No, hot food should not be directly frozen in the refrigerator, because when hot things are put into the refrigerator, some heat will be brought into the refrigerator, the refrigerator needs to lower the temperature, which will increase the burden on the refrigerator, hot food will increase the temperature around it, the refrigerator has to operate at high power, the food will also suck into the refrigerator when it is cold and shrinking, and the food stored in the refrigerator is easy to spoil.

As for whether hot meals will damage the refrigerator if they are placed directly in the refrigerator, there is no need to worry about this at all. Modern refrigerators have high refrigeration efficiency, and putting hot meals in the refrigerator will only slightly increase the power consumption of the refrigerator, but this is within the normal operating range of the refrigerator.
