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.

Method
Test type: kinetic
Testing time: one test 2 minute – 40 Tests/hour.
Are possible test sessions with several samples, up to a maximum of 16.
The system is supplied pre-calibrated and ready for use.
It is also possible to standardize the system using samples with a known value.
Calibration Curve / Correlation Data
CDR PalmOilTester Iodine Value test shows a good correlation with AOCS Official Method Cd 1d-92. for refined and crude palm oil and palm kernel oil
Principle of the test
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).
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.
Reagent test Kits
The reagents are packaged in foil pouches containing 10 tubes useful to perform 10 analyses.
This is the minimum package that allows the use of CDR systems even to those who need to make a few analyses, thus not wasting reagents.
There are also boxes of 100 tests, however, packaged in 10 bags of 10 tubes containing the reagent.
Code *300561 suitable for 10 tests
Code *300560 suitable for 100 tests
The reagents have a shelf-life of 12 months.
Sample Handling and Usage of Curves
Crude or refined palm oil, and palm kernel oil. Solid samples at room temperature must just be heated
| Curve | Code | Meas. range I.V. (g/100g) |
