Whey protein stability

[Meg_s]

Hi there, I remember reading that once you mix whey protein into a liquid it should be used up within an hour because it becomes unstable or something.
Is there any truth to that?
I was hoping to mix up some shakes to drink throughout the day but don't want to have the liquid sitting there if if shouldn't be.

No, whey powder will be ok, some MRP's you might have trouble with depending on what its made of.
