What are time-temperature integrators?
Time temperature integrators (TTIs) are food grade enzymes encapsulated in small tubes which mimic the thermal death
kinetics of specific target microorganisms, for example Listeria monocytogenes. Once prepared, TTIs brought to site are put through the thermal
process within a product. The resulting enzyme activity is measured in our labs to determine whether the thermal process is sufficiently robust.
TTIs can be used for validation of challenging thermal processes such as oven cooked products with low clearance, frying
processes where the environment is too harsh for temperature measurement equipment, or for hot fill processes where specific corners of packaging
