Kinetic parameter estimation of time-temperature integrators intended for use with packaged fresh seafood [electronic resource] /
ABSTRACT: The United States Food and Drug Administration (FDA) is concerned about the possibility of Clostridium botulinum toxin liberation before detectable spoilage of reduced-oxygen packaged (ROP) fresh fish. The FDA suggests that temperature conditions favorable to toxin formation are likely to occur within the distribution channel; therefore sufficient temperature monitoring is required in order to ensure safety. Time-Temperature Integrators (TTI) are proposed as one mean to control product safety. Six TTIs were tested for their suitability with ROP seafood. Three commercially available TTIs studied were Vitsab M2-10, Vitsab C2-10, and Lifelines Fresh Check TJ2. Three prototype TTIs evaluated were the Avery Dennison T126(1), T126(2), and T126(4). Methods to convert L*a*b* color readings to response rates were developed or adopted for monitoring thermal response of the respective TTIs.
