The thermal death time is the time taken to kill a bacteria at a specific temperature. Here at 75 degrees Celsius, the bacteria is able to survive till 10 and 20min of exposure, but at 30min of exposure, the bacteria isn't showing any growth and hence the bacteria is being killed at this time for this temperature. Hence the thermal death time for the bacteria at 75 degrees Celsius is 30min.
If you have any query kindly comment before giving thumbs up. Thank you.
