Why do apples turn brown? I mean, I know that it's to do with the air... but what is apple made of? Which part of it turns brown after reacting with oxygen... or is it oxygen? Is it something else in the air? I can't imagine it to be nitrogen as it doesn't do much, but still..... What in them turns them from creamy-white to brown?Â
I know if you leave them long enough then they shrink - dry out, so maybe they're made mainly of water (like us in that respect, although we're about 61% Oxygen and only 14 or so % Hydrogen... it's cause they're so titchy!). Which makes sense. But is it something to do with water that makes them brown or something else? Parsnips do it too, though to a slower and lesser extent. And they're less juicy, therefore have less water. Hmmm...
Wow, I'm a barrel of fun! Although all this speculation is in the stead of revision for large scale structures (ie Galaxies nad the Universe... I mean, how much larger can you get?!?). Did you know that we're "falling" towards the Virgo Supercluster (of Galaxies), which in turn is falling towards the Hydra-Centaurias Supercluster and that Andromeda is going to collide with us? Poor old Earth! Of course, that last won't be for another billion years so we'll all be dead anyway. And the sun will probably have incinerated the Earth by the time any of the others happen so we'll definitely be dead by then! And, hey, maybe we'll even be starting up again as a new star (nice to know your death is useful!).
But why do apples go brown?!?!?!?
