I usually eat a yogurt as part of one of my meals during the day, so I added 2 scoops of whey protein isolate powder to nonfat vanilla yogurt and mix it up real good. I did that this morning and put the container in my bag for work at 8AM. At 10AM I went to get it and when I opened it, it had completely liquified. I tasted it and it was absolutely vile. It tasted like medicine.

Not sure what chemicals they had that didn't mix, but I figured I'd share in case someone else was considering it.

Presumably because you left it for 2 hours unrefridgerated. Didn't your tub of whey say anything about consuming within a certain amount of time? :P

I mix protein powder with yogurt all the time... it tastes great. But I mix mine fresh, right before I eat it. I never let it sit... you might try that next time.

I used to do this a lot, too. I did at times pack it for meals later in the day (mixed hours before), and never had a problem. So it's something about the combo the OP used, not the the generic yogurt/protein powder combo.

This might be similar to the reaction that happens when you put a saliva coated spoon in a baby food jar, then store it for later use. We've had a couple of those liquify as well. It might not matter whether the yogurt is in a cooler, fridge, or whatever.

Some of the less yogurt-y yogurts actually have added whey as an ingredient. So it's something probably with additives in this particular combo here I suspect.

Lots of stuff that is found in a yogurt container is not really that close to real yogurt these days, so who knows?

I have also started doing this, often mixing it up to 8 hours before consuming it and I have never had an issue with it. I always keep mine in the fridge or in a cooler with ice packs though so if you kept it at room temperature I don't know.

No, it was refrigerated for all but my 20 minute drive to work.
