What is the main chemical cause of oils and fats becoming rancid and developing a bad smell?
Answer and explanation
Correct answer: Oxidation
Oils and fats, especially unsaturated fats, react with oxygen in air and undergo oxidation. This oxidation produces foul-smelling substances and makes the oils or fats rancid; the process is called rancidity. Reduction is the opposite of oxidation, so it does not cause rancidity.
