Fingerprinting of Oils and Fats Using GC-MS in Combination with Chemometrics

Oils and fats are widely used in the commercial manufacturing of food, preparation of fast food and domestic cooking as they enhance flavor and aroma of food. Thus the authentication of oils and fats is of paramount importance not only to consumers but also to manufacturers and local regulatory authorities. In view of the great demand for reliable techniques for the identification of various types of oils and fats, the feasibility of GC/MS with the combination of chemometrics in the differentiation of oils and fats was evaluated.
