Ben Odom asked. This is what the NOMSG group has to say:

Maltodextrin: Presently being researched. This is a hydrolyzed corn starch.
There is a possibility that it is either contaminated with MSG in its
manufacture process, or that MSG is added to it. We will keep you posted.
If, however, you've been unable to trace a suspicious MSG reaction, check
the product for maltodextrin.
