What is the main chemical process behind bad taste and smell of oils and fats?
Answer and explanation
Correct answer: Oxidation
The spoilage of oils and fats is called rancidity. When these substances remain exposed to air, oxygen reacts with their components and produces unpleasant-smelling and unpleasant-tasting substances. This chemical deterioration is oxidation, so option D is correct. Precipitation forms an insoluble solid, electrolysis uses electric current, and galvanisation protects iron with zinc; none explains rancidity.
