Dalda is prepared from oils by

  • oxidation

  • reduction

  • hydrolysis

  • distillation


B.

reduction

Oils (liquid glycerides) react with hydrogen in the presence of metal catalyst (like nickel) to give saturated glycerides (semi-solid glycerides) ie, fats. Thus, vegetable ghee (Dalda) is obtained by the hydrogenation (reduction) of oils.

                                 Oils + H2 → Dalda
