The Food and Drug Administration requires the disclosure of total unsaturation of commercial products as an indication of nutritional value. This unsaturation is a guide to the expected stability of food additives, such as edible oils and foods in which they are used. Unsaturation is typically evaluated as an iodine number, calculated for these additives based on their consumption of iodine through addition across the carbon-carbon double bonds. This titration method can typically take 45 minutes.
The investigation presented develops an alternative method for determining iodine numbers of some common oils using a computerized infrared spectophotometer. The analysis time, as compared to the titration method, is reduced by 20 fold.
