  • In order to investigate the nutritional quality of Bamei pig muscle,their amnio acid composition of dorsal muscle and abdominal muscle were determined and analyzed by automatic amnio acid analyzer,and evaluated by FAO/WHO model. The results showed that 17 kinds of amino acids were detected in the dorsal and abdominal muscles of Bamei pig. Except for the content,there were significant differences in the distribution,proportion,and composition of amino acids between the dorsal and abdominal muscles showed consistency. The values of EAA/TAA and EAA/NAA accorded with the requirements of the ideal protein by FAO/WHO. After scoring,Met+Cys was the first restricted amino acid,Lysine content was surplus. The amino acid composition was very close to the FAO/WHO mode and the standard protein model,indicating that Bamei pig had high nutritional value. The flavor amino acids were abundant in dorsal muscle and abdominal muscles,accounting for nearly 50% of the total amino acid content,and the abdominal muscles tasted more delicious than the dorsal muscle. As a result,Qinghai Bamei pig had a complete variety of amino acids,which had high nutritional value and delicious taste. As a local quality pig breed resource,it had the development potential.
