Project Description


    TTI labels show whether a product’s temperature and storage have been managed correctly.Inappropriate temperature fluctuations are known to be the major cause of food spoilage and illness associated with it. A Time-Temperature-Indicator (TTI) is a simple device (label) that displays a visual summary of the elapsed time-temperature history of the product to which it is attached. A TTI can be used on any product that is sensitive to temperature.

TTIs allow the customer to recognise whether products have been handled and stored correctly. Originally developed for highly sensitive and high-priced goods, TTIs have strong application potential in the food industry. Commercially available intelligent packaging concepts are usually based on labels showing a visible change in response to time and temperature of the product or the presence of certain chemical compounds. The basic principle of TTIs is a time-temperature dependent irreversible colour change that reflects the full or partial temperature history of a single product.

TTIs can be used to monitor the temperature exposure of food products during distribution, from production until they are displayed at the supermarket. They allow targeting of responsibility and serve as a proof of compliance to contractual requirements by the producer and distributor.

TTIs also help determine “sell-by-dates”. Without information on how the product has been stored, it is impossible for the industry to accurately determine by when a product should be sold and consumed. Suppliers are therefore obligated to reduce the shelf life of products, reducing possible revenue. Thus TTIs have strong potential use for both industry and consumers.
