Smart Cartons Warn You When Milk Has Been Out For Too Long!

Wondering if that milk on the counter had been spoiled for being out of the fridge for too long? Sure, you could sniff it to test its safety, but no one likes getting a nose full of sour milk smell. Tetra Pak now introduces its new smart cartons that would tell you at a glance whether the milk inside is still good or needs to be dumped. They change color when left out of the refrigerator for too long, making that exploratory smell test unnecessary.

Scannable chips embedded on the cartons’ exteriors will give all kinds of information about the contents, including how long the container has been out of the fridge and even which cow and which farm the milk came from. Tetra Pak plans to introduce the smart cartons in China, Brazil, Russia and India in 2013.
