I’m really curious. How do you pasteurise an egg without cooking it?
They do heat them, and evidently it does affect the egg’s nature somewhat. There are recipes I’ve seen for things like eggnog that say you can use them but that they won’t froth as well.
Just a WAG, but radiation?
Quick heating, it seems: short article here .
There’s also this article (scroll down below the “apparent bottom”) that tells you how to pasteurize eggs yourself at home.
