Whey - 'Cross flow ultra filtration CONCENTRATE'??

[cunninglinguist]

I use Dymatize's "Elite Whey Protein Isolate", which is mostly Ion-exchange whey - but lists 'Cross flow ultra filtration concentrate' as it's second protein ingredient...

Does this even exist?? I thought "cross flow micro/ultra filtration" techniques always yielded whey ISOLATES, not concentrate?

And to add to the confusion I can't find ANY other brand or even any web-based articles that mention the 'concentrate' version of this cross-flow-filtration whey.


Anybody have the necessarry info or backround to enlighten me here? Thanks :-D
