Time Temperature Indicators

Time Temperature Indicators (TTI’s)

Food waste is a global public policy issue. The Food and Agriculture Organisation of the United Nations (FAO) estimates that one-third of food produced for human consumption is lost or wasted globally, which amounts to approximately 1.3 billion tonnes per year.

This waste has a huge environmental impact.

In addition it is paramount that food safety is monitored from source, through transit, to shelves and into the home.

TTIs offer a visual indication of whether perishables, such as foodstuffs or pharmaceuticals have experienced any undesirable time-temperature histories that might cause them to spoil.

Integrated into packaging and operating over a broad spectrum of time and temperature, the indicators can deliver a step-change in the monitoring of perishable’s condition from source, through transit, into retail and the home.

Nano-materials integrated as polymeric crystals into packaging can be tuned to change colour through a drying cycle effected by time and temperature.

Food producers, retailers and consumers confidently judge the condition of food by the colour of an integrated packaging label.

Research Stage

Proof of concept devices have been produced. The team are now fine tuning for particular applications.
