Carbon stable isotopes, fatty acids and the use of NIRS to differentiate IBERIAN pigs

[EN] This study explores the viability of the application of Near Infrared Spectrometry (NIR) for the rapid prediction of the ratio of 13C/12C stable isotopes and fatty acid composition in Iberian pigs. The potential use of this technique for distinguishing samples according to the duration of the m...
