According to the National Health and Family Planning Commission, the concentration of acetic acid contained in smoked vinegar is very low, and the disinfection effect cannot be achieved at all.

The acetic acid taste of smoked vinegar can stimulate respiratory mucosa, especially lead to the onset or aggravation of tracheitis, emphysema and asthma. Many people think that vinegar has the function of disinfection and sterilization, probably because there is acetic acid in vinegar.

The sterilization of vinegar mainly depends on acid. Fumigating vinegar has two advantages: changing air pH and increasing air humidity. The significance of the two is mainly to reduce the adhesion carriers of bacteria such as dust in the air and block their transmission routes. So in principle, the meaning of smoked vinegar is mainly to block the spread.
