The TGeDSC curves of the fat from the cheeses (Fig. 1) showed three steps of mass loss. It is suggested that the first step was associated with the loss of low residual solvent used in the extraction of the samples, which in the DSC curves was observed as a large endotherm phenomenom, with mass loss of 3.92, 2.73 and 1.21% of initial mass. The second step was due to the decomposition of monounsaturated and polyunsaturated fatty acids, and the third stepwas due to the decomposition of saturated fatty acids, which in the DSC curves were observed as two exothermic peaks.
