Whether food can be eaten depends on the storage conditions. In fact, it's not what foods can't be eaten overnight, but how to store them overnight. It is better not to eat leftovers, leftovers, soup and pot-stewed food than staying at room temperature for the night, because it is easy for bacteria to multiply and cause diseases such as diarrhea.

The general advice of the scientific community is that leftovers and leftovers should be stored at room temperature for no more than 4 hours, and not more than 2 hours when the temperature is high. Leftovers and leftovers are boxed and put in the refrigerator when there is still residual heat. Although it costs a little more electricity, it is safer. This is because bacteria reproduce fastest at 20-30℃, so it should be cooled to cold storage conditions as soon as possible. In addition, leftovers and leftovers need to be thoroughly heated before eating, and they should not be stored in the refrigerator for too long.

Main points of leftovers storage

1 Leftovers should be thoroughly cooled before being put into the refrigerator. This is because hot food suddenly enters a low-temperature environment, and the food center is prone to qualitative change. Moreover, the hot air brought by food will cause the condensation of water vapor and promote the growth of mold, which will lead to the mildew of food in the whole refrigerator.

2, meat dishes are prone to bacteria for 2 hours

Harmful bacteria in the air will attach to some high-protein and high-fat leftovers and multiply within 2 hours. Under the action of bacteria, protein and fat will produce harmful substances, such as hydrogen sulfide, amines and phenol, which are harmful to human body. Therefore, the leftovers should be put into the refrigerator within two hours after cooking, and put in shallow containers to facilitate cooling.

3. Don't leave leftovers for more than 6 hours. It is advisable to store leftovers without meals. The leftovers in the morning should be eaten at noon, and the leftovers at noon should be eaten at night. It is best to eat them within 5 to 6 hours. If the food is stored for too long, the bacteria in the food will release chemical toxins, and there is nothing you can do to heat these toxins.
