Well, not technically squeezed: I vitamixed (super blendered):
2 whole valen. oranges (just removed the orange outer part, but whole oranges went in the blender). 2 frozen banana, 3oz frozen blueberries. I added ice & water and blended into a nice juice for breakfast.
I really enjoyed it at breakfast. It tasted great!
I poured the rest into a plastic cup (tight lid) and put in fridge.
When I had some 8 hours later, it tasted kind of sour.
I had the rest 12 hours later and tasted even worse. I added another frozen banana, and blended in my little blender - magic bullet blender.
It still tasted 'off'.
So, what changed? (My taste buds or the juice)? For both breakfast & dinner I had baby back ribs which were cooked in V8 & molasses (not that much).
Is commercial juice & smoothies more stable because they add something too it? (like vit. c?) But heck: the fuit has vit. c.!!
Oh, wait: it wasn't until I typed this whole thing that I remember one potentially important thing:
I went out to lunch and had 13oz of commercial orange juice (not from concentrate).
Is it possible the 4X sweetness of the commercial OJ made my home made less sweet juice taste, well, less sweet?
Thanks for any thoughts or comments, Mike

This is a topic I got into a few weeks ago, it's pretty cool. I gotta start with a comparison so the differences are pointed out. And well, I find it super neat:
Juice from lemons and limes can sit for about 4 hours before the flavour begins to fade but will not become bitter. This is due to oxidized terpenes.
Now, fresh juice from an orange is delicious for only about an hour and then instead of mellowing, like the lemons/limes, it becomes bitter. Why? well, because it has limonin in it. That compound doesn???t form until fresh orange juice is squeezed and forms after it has sat for a while. When an orange is juiced, the juice sacks are broken, and the acidic juice and an enzyme promote the conversion of LARL into limonin.
Here - this is the piece I wrote about it with some really great sources to check out for general nerding out.

I'm going to guess that there's some oxidation going on, especially since you blended air into the juices.
