Does copper react with anything in a fruit juice?

Answer 1

Copper slowly reacts with air to form copper oxide. If you have a copper penny and see dark "dirty" patches on it, this is copper oxide.

Citric acid, found in some fruit juices, will dissolve copper oxide, which is why coin collectors wash copper coins in lemon juice.

Answer 2

Not a lot, but a little. Copper and zinc react with acid, and fruit juice can often be fairly acidic (especially citrus juices like orange, lemon, or grapefruit juice).
