Final answer:
The lowest temperature at which all microorganisms in a particular liquid will be killed within 10 minutes is called the thermal death point (TDP).
Step-by-step explanation:
The lowest temperature at which all microorganisms in a particular liquid will be killed within 10 minutes is called the thermal death point (TDP). It is the lowest temperature at which all microbes are killed in a 10-minute exposure.
For example, if the TDP of a microorganism is 70°C, then at temperatures below 70°C, all the microorganisms in the liquid will be killed within 10 minutes.
It is important to note that different microorganisms have different TDP values, and some heat-resistant microorganisms, like endospore-formers, may require higher temperatures to be effectively killed.
