Made in Norway: 'TimeTemp' for safer foods

Scientists at the Agricultural University of Norway (NLH) have developed a so-called smart indicator which will keep a running check on the quality of fresh foods.

Scientists at the Agricultural University of Norway (NLH) have developed a so-called smart indicator which will keep a running check on the quality of fresh foods.

In time this smart tag will replace today's "best before" or "use by" stamps.

The indicator contains a harmless chemical which continously records time and storage conditions, the result is registered by a strip which changes colour, and thus provides a continous status of the food item at any given time.

The smart tag is attached to the product, and it will tell both consumers and store keepers in detail how ripe the cheese or meat is, how they have been stored, and when it should no longer be consumed.

It will therefore also help reduce the amount of food which today has to be destroyed, because the "use-by date" has passed.
