How long can milk last?

Ever wondered what's the difference between regular and extended shelf-life milk?

It's pasteurization.

Pasteurization is a method of preserving foods by heating them to destroy bacteria. The key to preserving flavor is to cool it quickly.

*Regular milk is treated at 161 degrees F. for 15 seconds. It keeps about two weeks.

*Extended shelf-life milk is treated at about 280 degrees F. for two seconds. It's good for 60 to 90 days.

*Ultrahigh pasteurized milk remains fresh for up to six months if it is packed in asceptic containers under sterile conditions.
