Tetra Pak to unveil new smart carton that changes color when milk is sour; imbedded chip will contain details, such as the time left out of the fridge, the farm and cow that produced the milk

LOS ANGELES , March 26, 2012 () – Lausanne, Switzerland-based Tetra Pak International SA is developing a smart carton that will alert consumers about when milk is inedible, reported The Telegraph on March 26.

The carton will change color when the milk is left out of the refrigerator for too long, according to an article in the Financial Times.

A chip is being developed by Tetra Pak that will be embedded in the carton and contain details such as the amount of time that the milk was not refrigerated, according to the Times, The Telegraph reported.

The chip could also be scanned by a mobile phone, allowing the consumer to see such information as the farm and cow that produced the milk.

This is being done in a partnership with Aurora, a Brazilian food cooperative, reported The Telegraph.

Tetra Pak President and CEO Dennis Jönsson said that with scarcer resources that are increasingly more expensive “it is important to … do more with less.”

In a March 26 statement, the company indicated that product shelf-life was one of many new challenges and demands it faces in “a changing market landscape.”

Among the other challenges and demands mentioned were legislation, producer/consumer demands, consumer needs, distribution requirements and environmental impact, The Telegraph reported.

Tetra Pak said it would participate in the Anuga FoodTec trade fair in Cologne. The event starts March 27.

It also announced that its sales for the latest financial year were up 5% to €10.36 billion (US$13.81 billion).

Last year, the company introduced the first aseptic milk carton, which was among the more than 76 billion liters (20.0 billion gallons) of packaging it supplied for milk, juice and other beverages, reported The Telegraph.
