Determination of Iodine Value in Palm Oil

The most important application of the iodine value is to determine the amount of unsaturation contained in fatty acids. This unsaturation is in the form of double bonds which react with iodine compounds. The higher the iodine value, the more unsaturated fatty acid bonds are present in a fat.
Iodine value is used as a parameter in process control as well as a quality parameter in traded palm oil products.

Thanks to its simplicity, the innovative CDR method for the determination of Iodine Value (IV) in Palm Oil is ideal to be used during every process stage to monitor the quality of oil in real time and during the acceptance of crude oil, as well as during trading of finished products.


Test Principle

Double bonds react with iodine in alcoholic solution determining a variation in the reagent’s absorbance. This amount measured at 420 nm is indirectly related with concentration of double bond in the sample, expressed as IV (Iodine Value).
