corrosion
Corrosion (from the Latin word corrodes, meaning "to gnaw") is the irreversible damage or destruction of living tissue or material due to a chemical or electrochemical reaction. Example: A prime example of corrosion is rusting of iron or steel.
rancidity
having a rank, unpleasant, stale smell or taste, as through decomposition, especially of fats or oils: rancid butter. (of an odor or taste) rank, unpleasant, and stale: a rancid smell.The condition produced by aerial oxidation of fats and oils in food marked by unpleasant smell and taste is called Rancidity. For Example, Potato Chips when kept in air for a long time gives unpleasant smell and bad taste. ... Rancidity can be prevented by adding anti-oxidants to foods containing fats and oils.
oxidation
Oxidation is the loss of electrons during a reaction by a molecule, atom or ion. Oxidation occurs when the oxidation state of a molecule, atom or ion is increased. The opposite process is called reduction, which occurs when there is a gain of electrons or the oxidation state of an atom, molecule, or ion decreases.
