Summary

The United States Food and Drug Administration (USFDA) considers any hermetically sealed package containing fresh seafood as a reduced oxygen package if the oxygen transmission rate of the package is less than 10 000 cm3/m2.d. USFDA's recent Import Alert No. 16-125 effectively bans the use of reduced oxygen package for fresh seafood in the USA unless adequate temperature control and thermal history monitoring is used. Time-temperature integrators (TTI) are a potential method to satisfy this thermal monitoring requirement. Evaluation and selection of appropriate TTIs remains a difficult process for seafood manufacturers. Three commercially available TTIs and 5 prototype TTIs were evaluated for performance against the Skinner and Larkin botulinum toxin lag-time relationship. Isothermal treatments at 0, 5, 10, and 15 °C were used to determine Arrhenius kinetic parameters of TTIs. Computer models were used to predict and compare actual TTI performance under dynamic thermal conditions.
