I dont think so.. The mandrian oranges and most fruits like that are all packed in water or in a light sugar syrup.

Much less acidic than anything tomato based..

Bzzzzzt! Oh no... And so close to the bonus round too.

Tomato based foods have a pH around 4.0 to 4.8. Fruits are citric acid compounds and run in the range of 2.0 ish even diluted.

The reason acidic compounds go bad faster is because hydrogen (pH is a measurement of the concentration of hydrogen ions, or hydronium, in the solution) is the ultimate electron swappin tool in chemistry. Let any mix of organic compounds sit enou and you are going to start seeing those little critters start swapping H's like wives at a swingers orgie. A year later... Goop.

Not all medications are good for an exuberant amount of time. Each medication is specific to it degradation capabilities and times. Some oxidize and die, some unravel all by themselves over time, some are very UV or IR sensitive. It all depends on the molecular structure of the medication and the packaging and storage. Hell, some can degrade into some really nasty stuff. So remember this about old meds, "hey kid, don't put that in your mouth. You don't know what in it or where it's been."
