Question

In canning and retorting of foods, which of the following is the correct expression of Ball process time (B)?

• A. B = t\(_p\) + 0.42 t\(_c\)
• B. B = t\(_p\) + 0.30 t\(_c\)
• C. B = t\(_p\) + 0.50 t\(_c\)
• D. B = t\(_p\) + 0.25 t\(_c\)

Hint:

Ball’s process time is crucial for ensuring that food is adequately processed and safe for consumption. The come-up time is an important factor in calculating total processing time.

Answer 1

The Correct Option is A

In the canning and retorting process, Ball’s process time is the total time required to heat the food to the desired temperature and maintain it there for the necessary duration. The expression for Ball process time (B) combines the processor’s process time (t\(_p\)) and the come-up time (t\(_c\)), which is the time it takes for the food to reach the desired temperature before the process starts. The correct formula is: 
\[ B = t_p + 0.42 t_c \] where: 
- \( t_p \) is the processor’s process time, which is the actual time spent cooking or processing the food at the desired temperature, and 
- \( t_c \) is the come-up time, the time needed to heat the food to the desired temperature. 
Thus, the correct answer is (A) \( B = t_p + 0.42 t_c \).
