Seems like that should be an ordinary processed food. Maybe a little bit of Googleing will lead you to the original food stuff, or maybe someone figured out the process.
Every year, when I was in college, my parents would by the alumni assoc. care package of snacks. I always ate the corn nuts last, because they weren't my favorite ... but hey, free snacks are free snacks. When you're young, that is.
I also remember some annoying guy who'd post on every GC board he could find, "What was the Colonel's secret recipe." Wish I had this image back then.
