Тут тоже написано, что нельзя добавлять молочный белок в горячий кофе. Unfortunately, when you try to mix your whey protein in your coffee instead of creamer, you can find it clumpy and impossible to drink. There is a way to keep that from happening, though. Since whey protein is designed to mix in cold liquid, the trick is to mix the protein into some cold water first, and then add it to the coffee. Автор спрашивала об изоляте. Молочный белок и изолят - это разные белки.
