Color-Changing Labels Signal When Food Goes Bad [Video]

Insignia Technologies developed a label that tells people how long a package of food has been open.

Scotland-based startup Insignia Technologies developed a “smart” label that changes color over time to indicate how long a package of food has been open.

With the smart food label, the startup aims to help reduce unnecessary waste of food due to confusing or misinterpretation of food labels.

Insignia Technologies was founded in 2012 from a merger between Insigniapack, an ink printing service, and Novas Technologies, a spin-out company from the University of Strathclyde, where the patented technology used in the labels was initially developed.


The company recently raised almost £900,000 in a funding round led by investment group Equity Gap, along with Highland Venture Capital, the Scottish Investment Bank, the University of Strathclyde, and several private investors.

With the new funding, the company hopes to start commercial trials of the label in supermarkets and companies in the US, UK, and Europe.
