Question

The three microbial species shown in the graph where all treated at 70° C. When we have to sterilize a food product that contained 10⁷ bacteria, the time taken for each bacterial species would be:-

For species A :- 42 minutes

For species B :- 70 minutes

For species C :- 112 minutes

arrow_forward

Step 3

The D70 values for these three bacterial populations.

D70 for microbial species A= 42 minutes

B: D70 microbial species B= 70 minutes

C: D70 microbial species C =112 minutes

Please answer these questions below: please use drawings too (i learn best that way)

For the next three questions, assume D90 = 22 minutes.

At what temperature will you treat a food product?
How long does it take you to kill 90% of bacteria?
How long will it take you to sterilize a food product if it had 10⁹ bacteria on it?
