摘要 |
A full-history time-temperature indicator system which is capable of exhibiting a time-temperature dependent and visually detectable chemical reaction, useful for monitoring the time and temperature exposure of food products. The system comprises an immobilised reactant, such as Fe<3+>, and a mobile reactant, such as Fe(CN)6<4->, initially contained in separate compartments, and separated by a sealing. The system is activated by removing a sealing between the compartments whereby the mobile reactant in a time-temperature dependent manner is brought into contact with the immobilised reactant resulting in a visually detectable reaction signal.
