I know that cooking with whey protein powder isn't the best idea because it can denature the protein. And that citrus juices (like lemon) can denature protein as well, since lemon can be used to "cook" seafood sometimes. I was planning on blending some orange juice and my vanilla whey protein to create an orange julius taste, and I'd like to make a large batch and leave it in the fridge to drink whenever. But would the citrus in the orange juice have a negative effect on the whey? Immediately or over time?
