Someone recently stated in an article that Vanillin is the
same as MSG (Monosodium glutamate), which most of us know
to be quite false.

I happen to work for Bayer.  There is a division within Bayer
called Haarmann & Reimer.  They make Vanillin (pronounced
VAN-ih-lin... similar to lanolin in rhythm).  I gave H&R a
call and talked to a few people before I was connected to
someone in Aroma Chemicals.  This person sent me a sheet of
information about Vanillin.  Now it turns out that Vanillin
is made at one of our German plants (Bayer is a German company,
headquartered in Leverkusen), so I don't have immediate access
to further information.

I know that a lot of the following information is pretty heavy
and technical, and mostly doesn't have a lot to do with cooking,
but I am including it rather than leave too much out and cause
even further confusion.
