Why does storing food in airtight containers reduce rancidity?
Answer and explanation
Correct answer: The food has less contact with oxygen.
Rancidity is caused by the oxidation of fats and oils, producing an unpleasant smell and taste. An airtight container limits the food's contact with oxygen, so the rate of oxidation decreases and rancidity is reduced. Increased moisture does not prevent rancidity; it can instead spoil food in other ways.
