The process is a trade secret, but experts speculate that the milk is partially lipolyzed (vomited into), producing butyric acid, which stabilizes the milk from further fermentation.

I toured the factory in Hershey Pennsylvania when I was a kid, and I didn't see anyone vomiting except customers in the parking lot.
I just remembered something that seemed insignificant at the time: men wearing Hershey's coveralls would come out with fresh vomit pails, and bring the full ones back inside, for disposal I assume. Perhaps I'm just being naive?

The dirty bastards. I wonder what creates the vomit - human or animal? Perhaps it's not so unusual, I've had coffee before that's either been through a cat or a weasel depending on the translation from the Chinese on the packet... It was surprisingly OK.
