Question

Rancidity of oil is detected by:

• A. Saponification value
• B. Iodine value
• C. Peroxide value
• D. Acid value

Hint:

Peroxide value is an indicator of the early stages of oxidation in oils. A higher peroxide value signifies that the oil is more likely to be rancid.

Answer 1

The Correct Option is C

Peroxide value is used to detect rancidity in oils. It measures the amount of peroxides (primary oxidation products) present in the oil, which are formed during the oxidation process. The higher the peroxide value, the greater the extent of rancidity in the oil.
