Food should be left on the ground for the night. Is it right or wrong to be more than 10cm away from the wall and the ground?

That's right. In many ordinary packaged foods and self-produced bulk foods in supermarkets, most of the marked preservation methods are: room temperature preservation. Normal temperature is not the weather temperature at that time, but generally refers to 20℃-25℃ to ensure food safety. Whether it is milk or drinks, most of them are marked with the words "stored at room temperature", but many people don't know how many degrees Celsius "room temperature" is.

Only the room temperature is marked, not the specific temperature, which really makes many people don't know how to keep drinks. The deterioration of milk should be the responsibility of the manufacturers, because their "normal temperature" label is too vague.

Extended data:

The room temperature in water treatment is slightly different, some are 15℃, some are 20℃, some are 25℃ (such as solubility and solubility product, different substances have different methods), and the ionization degree of water is calculated at 22℃.

There are several normal temperatures for HVAC, such as unmanned room 10℃ and occupied room 18℃.

In the chemical system, the design temperature of normal temperature is >: -20~200℃

In the pharmaceutical industry, normal temperature refers to 10-30℃, and imported products also refer to 15-25℃.
