I'm not an expert here, I just speed-read the paper, so I'm happy to be corrected! One probably dumb question: Does diacetyl (and the other chemicals) always have to be present in the original liquid, or is it that it can be formed through some reaction as the contents are heated up?

  It can also be produced by the heating process, even if it is not an ingredient. The levels are very small, however.
