Process Evaluation Techniques

Process evaluation, also called process determination, is the science of determining the F-value for a given process time or the process time required for a given F-value. If the heat penetration curve has been determined, then the fh- and j - values will be known and the appropriate methods can be used. The methods can also be used to determine the effect of altering the can size or the temperatures on the F-value. The importance of these methods for maintaining the safety of sterilized canned and packaged products cannot be overstated.
