It's In A Twinkie

There are reportings of Twinkie shortages from coast-to-coast.  Get your hands on some and give them out as Hostess shuts things down.  The game is called “It’s In a Twinkie”.  Grab the list of ingredients of a Twinkie here (there are 37 of them).  You name the preservative.  If the listener correctly guesses whether it’s in an actual Twinkie, they win one of the last ones available.
