The acetyl value is defined as the mg of potassium hydroxide (KOH) required to neutralize the acetic acid obtained by saponifying 1 g of an acetylated fat or wax. It is a measure of the hydroxyl content of the sample. In using the Andre-Cook formula the calculations are based on the weight of acetylated fat. The hydroxyl value is defined as the mg of KOH equivalent to the hydroxyl content of the sample based on the weight of unacetylated fat. Applicable to normal animal and vegetable fats and oils.
