Full history time-temperature indicator system |
摘要 |
<p>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 immobilized reactant, such as Fe<SUP>3+</SUP>, and a mobile reactant, such as Fe(CN)<SUB>6</SUB><SUP>4-</SUP>, 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 immobilized reactant resulting in a visually detectable reaction signal.</p> |
