  • Time-temperature indicator system I
    Patent number: 9689749
    Abstract: The present invention relates to a time-temperature indicator system useful for monitoring the time and temperature exposure of foods, nutraceuticals, pharmaceuticals, cosmetics, chemicals and other products. The system provides improved time-temperature sensitivity, time-temperature sensitivity control and a response which better reflects that of the reactions leading to quality loss of the monitored product. Further, the invention also relates to a combination comprising a time-temperature indicator system and a product storage container or a bag closure device. A method for producing said time-temperature indicator system is also part of the present invention.

  • Full history time-temperature indicator system
    Patent number: 7290925
    Abstract: 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 Fe3+, and a mobile reactant, such as Fe(CN)64-, 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.
