The temperature at the slowest heating location (coldest point) for a food in a can is as shown. Estimate the reference thermal death time (F0) for the thermal process. If the D value of a microorganism at 121C is 0.8 min and the initial microbial populations is 104 cells per container. Estimate the spoilage probability of the thermal process (compute "r"). Your spreadsheet should be designed to be able to take in different length of data (up to a maximum of 5,000 rows of data) and different time intervals. Killing tempeartuere starts at 75C (Or: No killing occurs when the tempearture < 75C, or F121 = 0 if temperatrue < 75C). The spreadsheet requires dynamic functionality, wherein you solely input the Temperature Vs. Time data (varying in length), and it automatically calculates F0 and r.
