Question

______ is the better way of stating thermal death time.

(a) F0 value

(b) F value

(c) D value

(d) Z value

I have been asked this question by my college professor while I was bunking the class.

My enquiry is from Heat Transfer Applications topic in portion Heat Transfer Applications of Food Processing Unit Operations

Answer 1

The correct choice is (b) F value

To explain: Thermal death time which is also known as TDT is defined as the time taken to destroy a specific microbe at a particular temperature. F value is defined as the time required killing all spores or vegetative cells at 1210^oC. Therefore F value is the better way of stating thermal death time.
