HMF?

Shouldn't have thought such a small dose would have mattered.

Anyhow, that mention of acid reminds me that Rob Currie, our Canadian 
researcher who has done HFCS work, said something in one of his 
presentations on the topic, about titratable acid.  His wife, apparently is 
a chemist and he got some special perspective from her.  It was over my 
head, but somehow, if I got it right, even in a neutral solution, there can 
be some acids remaining from the manufacturing in some HFCSs.

Maybe someone knows about this?
