IODINE NUMBER Meaning and
Definition
-
The iodine number is a measurement used to quantify the degree of unsaturation or the level of double bonds in fats, oils, and other organic compounds. It indicates the capacity of a substance to react with iodine. Specifically, the iodine number represents the amount of iodine, in grams, that can be absorbed by 100 grams of a particular substance.
The process to determine the iodine number involves the addition of iodine in the presence of a non-aqueous solvent, usually carbon tetrachloride or chloroform, to the substance being analyzed. Through a chemical reaction, iodine molecules react with unsaturated bonds, forming a complex. The unreacted iodine is then determined by a titration method, with the end point being indicated by a color change.
The result of the iodine number test is frequently expressed as milligrams of iodine absorbed per gram of substance. The higher the iodine number, the greater the unsaturation present in the substance. This information is particularly important in determining the quality of oils and fats as it directly influences their physical properties and oxidative stability. Oils with higher iodine numbers are more prone to oxidation, while those with lower numbers are more stable and have a longer shelf life.
The iodine number analysis is widely utilized in the food industry to evaluate the quality and purity of edible oils, as well as in the cosmetic and pharmaceutical industries for assessing the characteristics of various substances.

Etymology of IODINE NUMBER
The term "iodine number" refers to the measurement of the amount of iodine that can be absorbed by a specific substance. The etymology of the word "iodine" originates from the French word "iode", which was derived from the Greek word "iodes", meaning "violet-colored". Iodine itself is a chemical element with a bluish-black color. The word "number" in this context simply refers to the quantitative measurement or value assigned to the absorption of iodine.
