Parmalat

[insider]

What do they do to Parmalat so that it can remain unrefrigerated on store shelves? How long can it remain in that form before it goes bad?

Parmalat’s Milk contains 100% fresh dairy milk, with no chemicals or preservatives. In fact, Parmalat’s Milk Box contains the purest milk possible, because Parmalat pasteurizes the milk at Ultra-High Temperature (UHT), bringing the milk to 284° F and killing all the bacteria. Traditional refrigerated milk is only heated to 170° F, which means it needs refrigeration to prevent spoiling. After UHT pasteurization, Parmalat seals the milk in an aseptic, seven-layer box. It remains good to drink for six months without refrigeration (refrigeration is required only after opening).
