What Is The UWI Label?


A SCOTS inventor has developed a new labeling system which shows when food is unsafe to eat.

It’s hoped that the new technology, dubbed the UWI label, could help reduce the amount of wasted food, as well as help consumers save money and preventing them falling ill.

Pete Higgins came up with the idea after he almost served out-of-date mayonnaise to his young son and has spent the last 18 months developing it with scientists from Heriot-Watt University.

The label reacts as a soon as a food jar or packaging is opened then gives a clear and simple visual warning when the product is no longer safe to consume.

It is triggered as soon as packaging is opened and will then begin a countdown to show exactly when a product expires – with a display showing green while the product is safe to use or consume – replaced by a red warning.

Pete said:

“Everyone who sees the UWI Label instantly understands it and asks why something like this doesn’t already exist. “
