In chemistry, the iodine value (IV; also iodine adsorption value, iodine number or iodine index) is the mass of iodine in grams that is consumed by 100 grams of a chemical substance. Iodine numbers are often used to determine the degree of unsaturation in fats, oils and waxes. In fatty acids, unsaturation occurs mainly as double bonds which are very reactive towards halogens, the iodine in this case. Thus, the higher the iodine value, the more unsaturations are present in the fat. It ca… WebbIn GO, for example, after 360min of heating at 180°C, oleic acid content increased by 26.83%, while linoleic and linolenic acids decreased by 9.81% and 66.48%, respectively.
