    Denaturation of Whey Protein


    So, today, I decided to just have a quick lunch of oats and protein. I mixed in half a serving of ATW Cinn Bun Lean and Fit and Instant Oats (unflavored, 1 serving = 40g) added about 6 -7 ounces of water, mixed a bit and nuked it.

    After I was eating it, I am thinking about denaturation and breakdown of the protein while nuking it. Does anyone know the temperature required to begin denaturation of whey isolate protein? Did I just waste a scoop of protein? Thanks for feedback!

    According to this, the breakdown of the good stuff happens at 60 deg celsius which is ~ 145 deg F.

    I'd probably say... No, but I am not certain either.

    Here's an article from Paul Delia, CEO of AST:

    Yes, heat will severely damage whey protein and along with acid processing, heat is whey's worst enemy. I'm going to let you in on a dirty little secret other supplement companies sure wish I would keep tight lipped about. Most whey protein is heat damaged during processing and therefore heat damaged (cross linked) before it’s even put into the container to be sold. Processing whey protein without heat is a much lengthier and more costly process and therefore, the majority of the companies selling whey protein supplements do not use this more expensive whey protein. They may claim “cool processed” on their label, but the fact is, the protein is processed with heat, it's denatured (cross-linked), and it's very poorly utilized in the body. As a consumer, you have no way of knowing this. However, there is a big giveaway, if it’s cheep, it’s cross linked and far less effective.

    Understanding heat and its effect on whey should tell you that microwaving VP2 Whey Isolate with your oats is not a good idea. We go to great lengths and expense to ensure our undenatured whey isolate is produced in a cool environment from beginning to end. Don’t reduce the potent muscle building effects of VP2 Whey Isolate by subjecting it to heat.

    If you like to use VP2 with your oats, cook your oats, let them cool to a lukewarm temperature and then mix in your VP2 Whey isolate. This tastes great and provides you with the potent muscle-building effects of VP2 Whey Isolate with no compromise.

    Rick, I've read your thoughts about this elsewhere. I know I could have brought up an old thread but decided I am MORE important to have my own

    Still, I find that for every article that says YEP it's denatured, I find another that says it takes an incredible amount of heat to do so. I like the argument of the egg personally... I mean, it's obviously denatured (just look how the tertiary structure changes, no brainer there), but we still are able to use the protein from it within our bodies.

    So, the real question is... does denaturation even MATTER?

    It's hard for me to even imagine that it does matter THAT MUCH to the level that we are told ... I mean, look at many meats that we grill, fry, bake, broil, eat medium raw?
