Why does cows' milk expire faster than soy milk?

Lately, I picked up a carton of soy milk - last week, in fact, and it expires on May 09! Why does cows' milk, that's put out at the same time, last only half of that?

Thanks!

    From this site:

    (http://www.nbc4.com/answerstoaskliz2005/4494693/de...

    The expiration date on ANY type of milk depends upon how it was pasteurized. Organic milk AS WELL as conventional milk, can be pasteurized using Ultra High Temperature or High Temperature Short Time.

    If milk was processed using High Temperature Short Time that means it was heated to 161-point-5 degrees for 15 seconds which destroys 99-point-9 percent of bacteria. HTST is the federal standard for milk processors. Ultra High Temperature pasteurization involves superheating and cooling milk at extreme speeds, and extends the product's shelf life from 17 to 45 days.

    Because soy milk is a nasty un-natural substance. And like all evil things, they tend to hang around longer than you want them to.
