Q1. Saponification Value Is Used For The Determination Of?

A. Reducing Sugars
B. Pentose Sugars
C. Average Molecular Weight Of Fatty Acids
D. Rancidity Of Oil

Answer: Average Molecular Weight Of Fatty Acids

• Saponification Value = Milligrams Of Potassium Hydroxide (KOH) Required To Saponify One Gram Of Fat. When Fats Or Oils (Fatty Acids) Come Into Contact With Lye, A Base Produces Heat (Exothermic Reaction), And The Triglyceride Present In Fat Gets Converted To Fatty Acid And Glycerol.
  Sap Value = {(356.11000) / ([Mean MW * 3] + 92.09 – 54)}, Where MW Is The
  Molecular Weight Of Fatty Acids.
  Saponification Value Is Used For The Determination Of Average Molecular Weight Of Fatty Acids.
