Iodine value - Wikipedia, the free encyclopedia
The iodine value (or "iodine adsorption value" or "iodine number" or "iodine index") in chemistry is the mass of iodine in grams that is consumed by 100 grams of a chemical substance. An iodine solu...

This is followed by a discussion of the most commonly used stability value, the "Iodine Value" (IV). Finally, alternative stability measurements "Oil Stability Index" (OSI), and bis-allylic/allylic position equivalents (APE / BAPE) are mentioned.

The iodine value (IV) gives a measure of the average degree of unsaturation of a lipid: the higher the iodine value, the greater the number of C=C double bonds. By definition the iodine value is expressed as the grams of iodine absorbed per 100g of lipid.

Common structure indices are the iodine value (IV), the saponification value, and the hydroxyl value. Al-though modern analytical methods yield more detailed and re-liable information, structure indices are still widely used.

Iodine Value in Milk Fat; Introduction; The iodine value is a measure of unsaturation in oils and fatty acids. Measuring the iodine value of milk fat is used for processing of dairy products and quality assurance as well as determining the effects of animal feeding regimes on the degree of milk fatty acid saturation.

The reaction is complete after approximately 30 min, at which time potassium iodide is added. The liberated iodine is then titrated with sodium thiosulfate, using a standard starch solution as the indicator. ... Bruker Optics offers a solution based on FT-NIR spectroscopy for the determination of Iodine Value of edible oil.
