How Can Milk Be Unrefrigerated?

I was reading the ingredients on a Starbucks Doubleshot can, and what struck me as curious was how the cream and milk remained unspoiled while being in a can at room temperature. Bridget suggested it might be powdered milk, but I thought it would say that if that were the case.

So she called the 1-800 number on the can, and talked to a guy who answered the question.

Because the can is vacuum packed and milk pasteurized, it can remain unspoiled at room temp.
