How Long Can I Store Protein Shakes???

[uknownnn]

I usually prepare my protein shake (bananas + strawberries + whey + soy milk) in the morning and then drink it about 6-7 hours later (it would be stored in a fridge). The main reason for this being I work out in the gym at my office.

I was told that this might have some negative effects? Is it true?

TIA for the responses.

Why Soy Milk?

If you can add the protein powder in at the time of cosumption, that would be best.

If it's going to be sitting around, the biologically active / immunological properties of the protein would probably be diminished, but the aminos won't just disappear.

This is what I'd be concerned about - better have a clean container ... From Designer Whey's FAQs...

Q. Why should I mix protein into a drink and consume it immediately?
Immediately does not mean instantly. However, drinking within 30 minutes of mixing is smart since pure protein in the liquid form is an extremely fertile environment for airborne bacteria growth. Leaving a protein drink (reconstituted from powder) in a refrigerator for two hours is probably okay, but not overnight.
