ii)Iodine Number

Iodine Number

• It is defined as the number of grams of iodine taken up by 100 grams of fat or oil
• Iodine number is a measure of the degree of unsaturation of the fatty acid
• Since the quantity of the iodine absorbed by the fat or oil can be measured accurately, it is possible to calculate the relative unsaturation of fats or oil
