I guess I don't understand your question. Or rather, I don't understand your
statement that no individual veggie requires more than 50 minutes. Using the
same site (
http://www.uga.edu/nchfp/how/can_04/corn_kernel.html), you can
see that whole kernel corn, which is in the list of mixed veggies you
referenced, required 85 minutes for processing. The mixed veggies says 90
minutes. That's only a 5 min difference. That could simply be a 'safety'
addition or it could be to handle some other veggie (they say you can add
other veggies).
My best guess (please note I said 'guess') is that it is a density issue
because the corn can fill in spaces from other veggies and 'hide' from the
heat.
