In dairy products free fatty acids (FFAs) with fewer than ten carbon atoms can impart both desirable and undesirable (rancid) flavor notes, while long-chain FFAs are responsible for a soapy taste. The determination of FFAs in milk, cheese and other dairy products is particularly complicated owing to two main factors, i.e. FFAs (2 to 20 carbon atoms) represent
