This standard specifies the method for the determination of iodine content in food. The first method, inductively coupled plasma mass spectrometry, is suitable for the determination of iodine in food. The second redox titration method is suitable for the determination of iodine in algae and its products. The third method, arsenic and cerium catalytic spectrophotometry, is suitable for the determination of iodine in grains, vegetables, fruits, beans and their products, milk and their products, meat, fish and eggs. The fourth method of gas chromatography is suitable for the determination of iodine as a nutritional fortifier in infant formula and dairy products (except for infant formula for special medical purposes and formula for special medical purposes).
