Fats are made from edible oils using the process of:
Options
Answer: (3) Catalytic hydrogenation
Explanation:
Edible oils (liquid fats, containing unsaturated fatty acids) are converted into solid fats (like vanaspati/vegetable ghee) through the process of catalytic hydrogenation. In this process, hydrogen gas is bubbled through the liquid oil at high temperature and pressure in the presence of a nickel catalyst. The hydrogen adds across the double bonds of unsaturated fatty acids, converting them to saturated fatty acids — making the oil solid at room temperature. Simple hydrogenation (option 4) without specifying the catalyst is incomplete; the industrial process specifically uses catalytic hydrogenation.
