Time temperature integrators

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 are targeted.
