A process that has long been commonly used to preserve sausage is canning or preserving. This type of sausage is packaged in closed containers (jars/cans). They are preserved in an autoclave to provide extended shelf life. Depending on the type of preservation involved, a specific temperature/time program must be followed to achieve the required F values. Measured values from the autoclave and the core temperature of the sausage are recorded and archived with the LOGOSCREEN nt for documentation.
