ABSTRACT:
A time temperature indicator for indicating temperature change over time is provided, comprising an immobilized enzyme and a substrate of the enzyme, wherein the reaction of the substrate catalyzed by the enzyme produces a reaction product in a time and temperature dependent manner and wherein the formation of the reaction product can be detected by monitoring a physical characteristic of the substrate and/or the product which is linked to its concentration. Also provided is a method of time temperature indication comprising the step of an enzyme-catalyzed reaction, a method of printing the enzyme-based time temperature indicator on a packaging material or a label, a printing ink or printing ink concentrate comprising components of the enzyme-based time temperature indicator and a packaging material or a label comprising the enzyme-based time temperature indicator.
