What is the main chemical cause of the bad taste and smell in oils and fats?
Answer and explanation
Correct answer: Oxidation
Oils and fats can react slowly with oxygen from the air, especially when exposed to heat, light, or air for a long time. This oxidation produces rancid substances responsible for the unpleasant taste and smell, so option B is correct. Freezing is a physical state change, precipitation forms an insoluble solid from a solution, and filtration only separates materials; none causes rancidity.
