I was just wondering if there was a specific term to refer to fruits when they have undergone oxidation. That is, their flesh turns a yellowish-brown. This usually happens when the fruit has been left in the open air. I seem to remember that a few years ago, someone told me it was called "rust". However, I think "rust" usually refers to a plant disease that is fungal, isn't it? Or does rust refer to both? I've searched up the dictionaries, but it doesn't seem to be so.
Is there a single term for this?
