A time temperature indicator (TTI) is a device or smart label that shows the accumulated time-temperature history of a product.[1] Time temperature indicators are commonly used on food, pharmaceutical, and medical products to indicate exposure to excessive temperature (and time at temperature).
Technology
There are a large number of different time temperature indicators available in the market, based on different technologies. Some devices are based migration of dye through a filter paper, while others contain pouches with bacterial fluids that change color when certain time-temperature combinations have been reached. To the degree that these physical changes in the indicator match the degradation rate of the food, the indicator can help indicate probable food degradation.[2]
Digital Temperature data loggers are available to indicate the full temperature history of a shipment to help identify the time period that out-of-tolerance temperatures were encountered. This temperature history can be used to calculate the loss of shelf life or the likelihood of spoilage. These small recorders are also used to identify the time (and thus location) of a shipment when the problem occurred, which allows for corrective action.
TTI's food industry
Time-temperature indicators can be used on food products that are dependent on a controlled temperature environment. Certain technologies can also be used for frozen food and the cold chain.
Benefits
Surveys within the EU projects "Freshlabel" and "Chill-on" have shown a positive feedback by consumers to the use of TTIs on food products. As TTIs help assure the cool chain of food products, they are expected to reduce the amount of food waste,[3] as well as reducing the number of foodborne illnesses.[4]
Regulation
The World Health Organisation regulates the use of TTIs for certain medical products. There is extensive regulation by the FDA on the use of TTIs on US seafood products.[5]
