Micellar Casein

Does anyone have a good explanation on the difference between Membrane Micellar Casein and other micellar caseins, and for that matter the difference between micellar caseins and non-micellar caseins, if there is such a thing?

I'm trying to decide between:
Aussie Casein "ProteinFactory.com is proud to introduce their new product "AUSSIE" Caseinate. The highest grade caseinate ever created"
Heliogen Casein, which is a micellar casein that has been instantized with sunflower lecithin instead of soy lecithin
Membrane Micellar Casein "Exclusive to ProteinFactory.com ... MMC is the premier version ... Superior to calcium casein and microfiltration micellar casein"

How do I decide which one to use?

The easiest, BEST way would be to buy one pound of each and self-experiment. If you did that AND came back to the board with your observations, you would best educate yourself AND all of us here on the board!

I agree, but I would like to learn what the differences are.

Quick reference for you,

Micellar casein is un-denatured. Caseinates, such as sodium casienate and calcium caseinate, are first processed with acid and then processed with either sodium hydroxide (sodium caseinate), or calcium hydroxide (calcium caseinate).

So ... are the Aussie and Heliogen Caseinates denatured?

Answered my own question after perusing through Alex's site for a bit.

Both PF's Heliogen and Micellar caseins are undenatured; they are separated from milk's whey constituent via a membrane filtration method vice an "acid bath" process.

Thanks!

So what does the "membrane" part of membrane micellar casein mean?

I don't know n I really don't care because PF carries the best proteins n personally of all the caseins I still like MMC the best. even tho I always mix all 3 caseins n sometimes ipi together.

I digest whey a lot better than casien, I just feel like my body breaks down n absorbs whey better. I love the cfm cause it has good nutrition value n the sodium is not high but so is tri fx. it is just such a wonderful protein supplement.

That's great, but like I said I'm trying to understand which ones are the highest quality. I like to learn and understand these things.

And it's not always as easy as trying it and seeing which one works for you, for example one might be grass-fed organic and one might be from standard milk from a conventional dairy... it might not be obvious from trying them which one is better, but there are still benefits from using the grass-fed organic stuff. Again, this is just an example.

Put another way, let's say PF.com came out with an MMC that was instantized using sunlfower oil lecithin instead of soy oil lecithin. Which one would be the higher quality (more pure, less denatured, less oxidized, god knows what else) - the Heliogen Casein or this new version of MMC?

Why is it such a no-no to have a discussion about the technical merits of the proteins in terms of source and processing methods??

IIRC the MMC is actually made from milk that is grass fed, though I don't know if it is entirely made from grass fed milk. So, MMC probably has slightly higher quality milk. However, Heliogen has better texture/mouth feel.
