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

2- Calculate 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
3- 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

Tenderness is defined as the slope of force versus deformation as a result of a single compression test

Juiciness definition is the difference between weight of filter papers (e.g., Whatman #40 placed at top and bottom of meet cut) before and after a single compression

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