These characteristics are directly related to diet and breeding style (free ranging in a particular Mediterranean ecosystem: the Dehesa). Given that current demand is not matched by the available resources, animal feed is increasingly used. GC-C-IRMS analysis of Palmitic, Stearic, Oleic and Linoleic Acid methyl esters allows for differentiating between pork raised in the traditional way and that fattened on animal feed. Although a value of δ<sup>13</sup>C<sub>C18:1</sub> = –25.9‰ is a good discriminator, exploratory analysis of principal canonical components is required to properly assign any unknown sample.}, number={2}, journal={Grasas y Aceites}, author={Recio, C. and Martín, Q. and Raposo, C.}, year={2013}, month={Jun.}, pages={181–190} }
