Determination of Iodine Value in Palm Oil
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 production stage in refinery plant to monitor the quality of oil in real time and during the acceptance of crude oil, as well as during trading of finished products.
Features & Benefits
- Faster and easier method compared to official titration.
- Test results are available in just 2 minutes
- Correlated with AOCS reference methods
- Very easy sample preparation: melted palm oil
- It does not require costly equipment and technical staff
- It does not involve handling of highly toxic reagents
Definition and Scope
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.
Instruments to Use
PalmOilTester: designed to measure acidity (FFA), Iodine Value (IV), DOBI & carotene content, Peroxide Value (PV), Anisidine Value (AnV) in palm oil
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).
Crude or refined palm oil, and palm kernel oil. Solid samples at room temperature must just be heated
Correlated with AOCS reference methods
CDR Iodine Value test shows a good correlation with AOCS Official Method Cd 1d-92. for refined and crude palm oil and palm kernel oil
correlation CDR Iodine Value test - AOCS for Refined Palm Oil
correlation CDR Iodine Value test - AOCS for Palm Kernel Oil
correlation CDR Iodine Value test - AOCS for Crude Palm Oil
