These foods are also not safe to put in the refrigerator, so be sure to take protective measures.

2. Yogurt.

As an organic food, yogurt can spoil in just a few hours if it is exposed to the air, so it should be sealed before putting it in the refrigerator.

3. Vegetables.

The shelf life of vegetables is also very short, generally only 2 3 days, when we put vegetables in the refrigerator preservation room, we must do a good job of disinfection and sterilization. This way, when you take it out, you won't spoil or even cause food poisoning.

When you put something hot in the fridge, the temperature in the fridge will rise. Then you don't meet the condition that "the inside of the refrigerator should be maintained at about 4 degrees".

In this way, the food stored in the refrigerator is prone to spoilage.

2 When you put something hot in the refrigerator, you bring some heat into the refrigerator, and the refrigerator needs to increase the workload to bring the temperature down, which requires electricity consumption and also increases the burden on the refrigerator.

3 Because the surface temperature of a hot object drops quickly, but the temperature inside drops more slowly, bacteria can grow in this process.

4 Hot food will raise the temperature around you, and the refrigerator will have to run at high power. Moreover, it will produce water vapor, which is easy to freeze when solidified on the cold plate, and the silver food will also inhale the peculiar smell in the refrigerator when it shrinks.
