The preparation of vegetable ghee involves
Correct answer: B. Hydrogenation
- A. Halogenation
- B. Hydrogenation
- C. Hydroxylation
- D. Dehydrogenation
Explanation
Vegetable ghee is prepared from vegetable oil which is a tri-ester of unsaturated fatty acids with glycerol. The unsaturation in vegetable oil can be eliminated by hydrogenation at high temperatures in the presence of nickel. This process converts unsaturated fats into saturated fats, making the oil solid at room temperature, resembling ghee. The other options are incorrect because they involve processes that are not relevant to the preparation of vegetable ghee.
