Iodine value test. Nut and sunflower oils with a dropping bottle of ethanolic iodine. This test determines the degree of unsaturation of a fatty acid. The more unsaturated an oil is the more double bonds there are between carbon atoms. The double bonds react with iodine,which can be seen by a dilution in the iodine's colour. Measuring the amount of iodine needed to make the iodine and oil solution retain the colour of the iodine,allows you to determine the degree of unsaturation | |
