How long does orange juice in a carton stay fresh if its unrefrigerated?

I got a carton of orange juice (tropicana no pulp) last night and forgot to put it in the refrigerator. I put it away when I got up this morning, but it sat for 10-12 hours on the counter.





Is it still good or does OJ in cartons spoil that quickly? It was never opened. Is it still OK to drink?

The general rule of thumb for any food left out is about 3 hours. You could open it up and smell it. Chances are it will start to 'ferment' first and smell a little like wine. I generally don't find it worth the risk because the whole time I am drinking/eating the item left out I think it tastes 'funny'.
Reply:Well im not a scientist or anything, if it was overnight then im guessing it wasnt extremely hot, and i dont think it would expire as fast as milk or anything like that, id say try a small glass and if it tastes bad then its bad.
Reply:If it was never opened it should be fine, of course if it was really warm in your house last night It might not be. But normally, orange juice is stays good for a while if it is not opened.
Reply:Orange juice is very acidic and as a result, little will grow in it. I would say 2 days at ambient room temperature (68 degrees F). If it is hotter where you live, 1 day max.
