Notes:
 Import your own data and vary Z  and Tr to  model F values. More

 Use the"new data grid" and "start and end  time"  controls along with the "time interval"  control to  define your input requirements.

 The no of log cycles that a designated  microbial  population has been reduced can  be calculated by  dividing the F value by the  D value at Tr. A 12 log  cycle reduction is  required for spores of Clostridium  botulinium in 'commercially sterile' low acid canned  foods.

If you find this calculator difficult to use try a simplified version where you replace the 'dummy data' with your own.
