How many degrees should the refrigerator keep fresh?

Adjust the temperature control knob to 2-3.

As we all know, in different seasons, the fresh-keeping temperature of the refrigerator should be adjusted to different grades, which not only saves electricity, but also better stores food and ensures that the fresh nutrition of food is not lost. However, many friends just adjust the temperature of the refrigerator in disorder, which eventually leads to the refrigerator not cooling or various failures.

The temperature of the freezer compartment is generally 4℃- 10℃. When food is taken out of the refrigerator, it needs a gradual heating process to be heated immediately. 4℃ to 40℃ is the suitable temperature for bacterial reproduction. Gradually warming up is equivalent to creating a good environment for bacterial reproduction. Once people eat leftovers that are not completely heated, they will not have diarrhea.

In fact, the principle of storing food at the fresh-keeping temperature of the refrigerator is to slow down the growth and reproduction of microorganisms, but it cannot kill microorganisms. The most suitable breeding temperature for most microorganisms is around 37℃, and some microorganisms can breed rapidly above 20℃. Although most microorganisms grow slowly below 10℃, some bacteria can survive and even reproduce at lower temperatures.

How to adjust the fresh-keeping temperature of refrigerator to save electricity: Generally speaking, the optional buttons of refrigerator temperature control are basically from 0 to 7, and the larger the number, the lower the temperature of refrigerator freezer. Generally speaking, we only need to adjust the refrigerator temperature to 3 in spring and autumn and to 1 or 2 in summer, which can achieve better energy-saving and electricity-saving effects.
