Definition of Acid Value from the PharmacyDictionary.in

Acid Value

The “Acid Value” is a measure used to quantify the amount of free fatty acids present in a substance. It is defined as the number of milligrams of potassium hydroxide (KOH) required to neutralize the free fatty acids in one gram of the substance. This value is particularly important in the analysis of fats and oils, as a high acid value typically indicates a high level of degradation or rancidity. It’s a key parameter in quality control and assurance in industries dealing with fats, oils, and similar substances.
