What Is Pasteurized Prepared Cheese?

processed cheese is a blend of lots of other cheeses. It was invented by Canadian James Lewis Craft of Craft fame. He came up with the idea of shredding it and then adding this stuff, which makes it kind of cuttable. And they pasteurise it so it doesn't ripen. So there's no use by date on it, presumably? Maybe there is for safety as in maybe after a certain number of years it does go off. But I'm not sure.
