Rancidity of oils and fats is the result of which chemical process?
Answer and explanation
Correct answer: Oxidation
Rancidity is mainly caused by oxidation of unsaturated oils and fats when they react with oxygen in air. The oxidation produces unpleasant-smelling and bad-tasting compounds, so the food becomes stale or rancid. Antioxidants, refrigeration, and airtight packaging slow this process by reducing oxidation. Therefore option A is correct; precipitation, electrolysis, and galvanisation are different processes and do not explain the spoilage of fats.
