Abstract

The aims of this study were to contribute to the characterization of meat quality covered by the protected geographical indication "Agnello di Sardegna" and to provide guidelines for the official controls system. Thirty "Sarda" suckling lambs granted by the "Agnello di Sardegna PGI" fed with maternal milk were slaughtered according to specification. Afterward, on psoas major, quadriceps femoris and longissimus dorsi samples, pH, color parameters, chemical and fatty acid composition were determined. The type of muscle affected the pH 1h (P≤0.001) that was lowest (5.93) in psoas major and highest (6.75) in longissimus dorsi. Muscle-related differences were observed in color parameters and in chemical and fatty acid compositions. Psoas major showed higher fat and total saturated fatty acid content (P<0.05). Longissimus dorsi showed higher values (P<0.05) of polyunsaturated fatty acids. Anatomical location of muscle is an important source of variation in some physicochemical characteristics © 2013 Wiley Periodicals, Inc.
