I photographed the Oregon Freeze Dry plant for the Bloomberg News wire service recently and learned all about how to make beef stroganoff last for 8-10 years. Oregon Freeze Dry is the largest food freeze dryer in the world, a process also known as lyophilization. They also cook all their food there, which I thought was pretty cool. One thing is for sure, if I ever need to survive some sort of end-of-days disaster, I'm heading here.
