Is the sterilization of tableware effective in boiling water?

Boiling water disinfection is high temperature disinfection. High temperature disinfection requires two conditions, one is that the temperature is high enough, and the other is that the time is long enough.

People who eat out generally worry that the tableware is not hygienic and will cause diarrhea. The bacteria that cause diarrhea are generally Escherichia coli, Salmonella, Vibrio cholerae, and Bacillus cereus.

These bacteria generally die in three minutes in water at 100 degrees Celsius, and it takes 10 minutes to die when the water temperature is 80 degrees Celsius. Some bacteria, such as Bacillus anthracis, require higher temperatures to die.

In view of the above situation, it is not difficult to conclude that simply ironing the tableware cannot effectively sterilize it. A simple ironing can not reach the sterilization conditions in terms of temperature and time. It can only remove some residual detergent and dust and stains on the tableware.

So if you want to sterilize, the tableware should be placed in boiling water or steam for 5-10 minutes. If it is placed in an infrared disinfection cupboard, you need to control the temperature at 120 degrees Celsius and place it for 15-20 minutes to achieve the sterilization effect.
