During the last 15 years, analytical methods (inmunological and enzymatic procedures) have been focused on the identification of meat species in raw, cooked and processed products. Near infrared reflectance (NIR) spectroscopy methods are attractive options due to the speed of analysis and minimal sample preparation. NIR spectroscopy has emerged in the last 30 years as a rapid method for testing the quality of intact samples from the light they reflect. One of the advantages of NIR technology is not only to assess chemical structures through the analysis of the molecular bonds in the near infrared spectrum, but also to build a characteristic spectrum that represents the “finger print” of the sample. The Pampa-Rocha breed of pig is originated from Uruguay and it has been a zootechnic resource related to medium to small farm production systems. The objective this study was to evaluate the potential use of visible (Vis) and near infrared reflectance (NIR) spectroscopy combined with chemometrics to identify and trace muscles from autochthonous breed of pig (Pampa-Rocha) and commercial cross (Pampa x Duroc) from Uruguay.
