What is an Iodine Value?
In analytical chemistry, measure of the degree of unsaturation of an oil, fat, or wax; the amount of iodine, in grams, that is taken up by 100 grams of the oil, fat, or wax. Saturated oils, fats, and waxes take up no iodine; therefore their iodine value is zero. Unsaturated oils, fats, and waxes take up iodine (unsaturated compounds contain molecules with double or triple bonds).
