Estimate Pasteurization Operating Conditions Some new pasteurization equipment is to be installed to replace some existing equipment for the disinfection of an unknown strain of bacteria. The current equipment operates at a temperature of 65C (150F). The corresponding D and Z values for the bacteria are 10 s and 12C, respectively. The initial bacterial count is org/100 mL. If the new equipment is to operate at 77C (170F) for 4 s, what level of inactivation can be achieved? If the new equipment cannot be installed, what time would be required at a temperature of 65C (150F) to achieve 4 log removal?
