Statement I: Peroxide value is a reliable measure of how rancid an old oil has become.

Statement II: Peroxides are the primary products of oxidation and break down as it proceeds.

In the light of the above statements, choose the correct answer.

  • A.Statement I is correct but Statement II is incorrect
  • B.Statement I is incorrect but Statement II is correct
  • C.Both Statement I and Statement II are correct
  • D.Both Statement I and Statement II are incorrect

Answer: B

The chemistry in the second statement is exactly why the first fails: a badly oxidised oil can show a low peroxide value because the peroxides have already decomposed. Anisidine value or a sensory panel is needed alongside it.
