Question Protein powder damaged when mixed with oatmeal?

I've been mixing my protein powder (muscle milk) with usually scolding hot oatmeal. Why not wait until the oatmeal has cooled down, you say? Whenever I mix them it significantly cools the concoction down (probably breaking some of protein's bonds). So IOW, I mix it scolding hot because if I waited for it to cool it would be too cool for my taste. The point/question: is this altering/negatively affecting the nutritional value from the protein power?

Another question, I have not done extensive internet searching but can someone recommend me to a good, cheap, low fat, keeps its integrity, homemade protein bar recipe. I 'ved been using a peanut butter/honey/oatmeal mix which is good but I'd like to switch to a healthier base. It does not have to taste good at all, it can be horrid for all I care. I just want something filling and nutritious to occupy my stomach during long school days. Thank you to everyone who responds.

Re: Protein powder damaged when mixed with oatmeal?

The protein powder mixed with oatmeal is fine. As for the protein bars, I've never made them homemade but that is probably the best way to go considering how expensive they are otherwise.

You're going to get a lot questions/comments/snipes about "low fat", just take it with a grain of salt.

Re: Protein powder damaged when mixed with oatmeal?

If using a natural peanut butter I'm not sure I would worry too much (unless you are eating a dozen bars a day). What is the recipe?

2 1/2 cups of peanut butter, microwave it for 1 minute to where its slightly melted... mix about 3/4 cup of honey mix them well then go anywhere from 3/4 to 1 1/2 cups of protein powder and mix well.... then add 3 cups of dry oatmeal, 1 cup at a time and keep mixing as it will be very thick... press everything down in a 9x13 pyrex pan and let cool for a few hours... quite delicious and they don't melt if you carry them around all day

Actually sounds pretty good. What powder are you using?

Re: Protein powder damaged when mixed with oatmeal?

Wow I can't believe that never crossed my mind!
Its called denaturization and this is the reason it mixes when it is hot .

I think you may very well be comprimising the quality of your protein.

Re: Protein powder damaged when mixed with oatmeal?

1. Coagulation of proteins actually probably increases absorptivity in humans.

For example, cooked eggs absorb in our bodies better than raw eggs.

Enzymes can work on denatured proteins just like they can work on non-denatured proteins.


2. Why low fat? If you need cals, especially if you're weight gaining, you need all the cals you can get.

Re: Protein powder damaged when mixed with oatmeal?

So your post suggests that a whey protein cooked will have a higher quality then when it is purchased?

Re: Protein powder damaged when mixed with oatmeal?

The protein may become denatured when exposed to heat but the primary structure--the order or sequence of the amino acids--will not change. Go go, Bio101.

Here's a decent lil' read on some protein questions from T-muscle: http://www.tmuscle.com/free_online_a..._about_protein (NWFS, except for some questionable images to the right of the article)

No, see the post above me.

Same structure. Just in a different shape.

Sometimes the structure affects absorptivity like in eggs. I don't think it will most of the time.

It also depends if the powder is in the form of amino acids or if it's in peptides.
