Does cooking soup produce oil fumes?

Actually, cooking soup or hot pot does produce oil fumes, but the amount is not as significant as quick stir-frying or deep frying.

During the process of cooking soup or hot pot, oil esters float on the surface of the water. When the soup boils, the oil esters evaporate into water vapor, and these aerosol particles of oil fumes disperse in the air.

Cooking Soup Also Produces Oil Fumes

We can also consider that after having hot pot, even if our clothes don't come into contact with the soup, the smell of hot pot still lingers on our clothes. This is caused by aerosol particles in the air settling on our clothes.
