Question

Decimal reduction time is the time required at a given condition to

• A. Change the temperature of a process by \(10^\circ\text{C}\)
• B. Achieve one log reduction in relevant microorganism
• C. Change microbial inactivation rate by 90%
• D. Change microbial inactivation rate by 10%

Hint:

Remember the terms:
- D-value: Time needed for a 90% (1-log) reduction in the microbial population.
- z-value: Temperature change needed for a 90% (1-log) change in the D-value.

Answer 1

The Correct Option is B
