problem1- Compute the processing times for achieving a process lethality (Fo) of 10 min (z=18F) for the following cases

a) fh = 30 min, jch = 1.40, RT = 260F, IT=150F, jcc = 1.6

b) fh = 55 min, jch = 1.55, RT = 260F, IT=200F, jcc = 1.8

problem2- find out the lethality achieved in the following process (z=18):

B= 60 min, fh = 50 min, jch = 1.68, RT = 250F, IT=150F, jcc = 1.2 B= 40 min, fh = 30 min, jch = 1.4, RT = 250F, IT=150F, jcc = 1.4

problem3- A meet industry want to know which of the following cooking time- temperatures could result a higher tenderness and juiciness
60 min at 80 oC, 40 min at 90 oC, and 30 min at 100 oC

Plan the experiment including materials needed, sample preparation, methodology and calculation.
