2. What is TTI? TTI changes in color according to time-temperature history. This color change indicates the change in quality of the accompanied food. Temperature Label Film Air Space Product

Values of activation energy (E a ) for different processes occurring in fruits and vegetables Product Q Ea (KJ/mol) Carrots Shredded Sliced Whole Respiration rate 79 70 55 Onion Respiration rate 35 Mushrooms Color change 63 Lettuce Color change 37 Strawberry Firmness loss 39 Fresh apple Respiration rate 29
3. (FI) As a subclass of intelligent packaging, a food spoilage indicator is a packaging system (or material) which uses metabolites as information to monitor the status of food spoilage.
3. Comparisons of the respective advantages and disadvantages of TTIs and FQIs Time-temperature indicators Food quality indicators Advantages Disadvantages Advantages Disadvantages Easily read Accepted quality assurance method, commercially available, cheap unit cost science understoodmaturing technology Do not directly indicate actual Seafood quality Easily read Directly indicate quality/spoilage potentially cheap Affixed inside pack Restrictions on formulation Difficult to apply (Smart Packaging Technologies. 2008. pp. 75-92)
3. Postmortem changes in fish meat (Food Control. 2005. 16: 301 307)
