Temperature monitoring device for food, comprises solidified medium which melts when threshold temperature of food is exceeded so that its initial shape is irreversibly lost

摘要

The device comprises a solidified medium specially chosen so that its melting point corresponds to the threshold temperature of the product being monitored. The initial shape of the device is selected so that if the melting point is exceeded over a given period then this shape is irreversibly lost, providing a visual indication that the threshold temperature has been exceeded. The device is secured or added to the product.
