Q. Which one of the following statements is true?
A) Saponification of oil yields a diol
B) Drying of oil involves hydrolysis
C) Addition of antioxidant to oil minimizes rancidity
D) Refining of oil involves hydrogenation
Explanation
(c)
Saponification of oils yields a triol (glycerol). Drying (hardening) of oils involves hydrogenation. Refining of oil is done by distillation or other such processes but not by hydrogenation.
Antioxidant are added to prevent the oxidation of oil, thus they minimizes rancidity.
