ISO 3961 Iodine Value Measurement in Fats and Oils
The measurement of iodine value is a critical analytical tool for the food & feed sector. The ISO 3961 standard provides a standardized method to determine the iodine value of fats, oils, and related materials. This parameter is essential as it indicates the unsaturation level in fatty acids, which affects the quality and shelf life of various products such as margarines, shortenings, and cooking oils.
The iodine value serves several purposes:
- Quality assurance: It helps ensure that fats and oils meet desired standards for purity and freshness.
- Process control: It aids in monitoring the refining process to optimize product quality.
- Product differentiation: It allows manufacturers to differentiate their products based on specific fatty acid profiles.
The test is particularly relevant when dealing with triglycerides, which are esters of glycerol and one or more fatty acids. The iodine value gives insights into the degree of unsaturation in these molecules, making it a key indicator for several applications:
- Determining the stability of fats and oils.
- Establishing the initial quality of raw materials before processing.
- Monitoring the effect of thermal treatment on fats and oils during production processes.
The methodology involves reacting a sample with iodine in the presence of an aqueous potassium iodide solution. The reaction is titrated against a standardized sodium thiosulfate solution, allowing for determination of the iodine value based on the amount of iodine absorbed by the fatty acids present in the sample.

Scope and Methodology
| Parameter | Description |
|---|---|
| Sample Preparation | The sample should be homogenized to a fine powder. Ensure the sample is representative of the batch or lot being tested. |
| Iodine Reactant | Pure iodine (I2) and potassium iodide (KI) solution are used in specific concentrations as per ISO 3961. |
| Titration Process | The titration is performed using a standard sodium thiosulfate solution, which reacts with the excess iodine. |
| Calculation of Iodine Value | The iodine value is calculated based on the stoichiometry of the reaction and the volume of titrant used. |
The process begins by dissolving a known quantity of sample in an appropriate solvent. The solution is then reacted with iodine, followed by potassium iodide to release free iodine. This iodine is subsequently titrated against sodium thiosulfate. From the volume of titrant used and the concentration of sodium thiosulfate, the iodine value can be calculated.
The precision and accuracy of this method depend on careful sample handling, accurate measurement techniques, and adherence to the standard procedures outlined in ISO 3961. This ensures that the results are reliable and comparable across different laboratories.
