摘　　要：为了研究不同羽色(白羽、麻羽、黑羽)静原鸡鸡肉的营养成分及其存在的差异性,以第5世代核心群的3个羽色(白羽、麻羽、黑羽)静原鸡为研究对象,采用直接干燥法、索氏抽提法、微量凯氏定氮法和国家标准GB5009.124—2016中氨基酸的测定方法分别对其胸肌、腿肌的初水分、脂肪、蛋白质、氨基酸含量进行了测定,并对其结果进行比较及分析。结果表明,白羽、麻羽、黑羽3个群体的静原鸡胸肌、腿肌的初水分含量分别为71.10%、70.35%、70.69%和72.14%、70.13%、72.08%,差异均不显著(P>0.05)。黑羽静原鸡的胸肌、腿肌脂肪含量分别为2.19%和3.12%,为三组最高,白羽静原鸡为最低。3个群体间麻羽静原鸡胸肌蛋白质含量(24.30%)最高,白羽静原鸡次之,黑羽静原鸡最低;3个群体间腿肌蛋白质含量差异均不显著(P>0.05)。3个群体鸡肉中氨基酸含量差异均不显著(P>0.05)。胸肌和腿肌中谷氨酸含量最高,天冬氨酸、赖氨酸、亮氨酸、精氨酸等含量次之。胸肌必需氨基酸、总氨基酸含量均是麻羽最高;腿肌必需氨基酸麻羽最高、总氨基酸含量白羽最高。该试验结果可为消费者购买静原鸡时的不同消费倾向提供参考。The objective of this study was to assess the meat nutritional components between Jingyuan chickens with varied feather colors (white, linen and black) and to evaluate their differences. The core group of the fifth generation of the Jingyuan chickens with three different feather colors were used as experimental animals. The contents of initial moisture, fat, protein and amino acid of the chest muscles and leg muscles were determined by using direct drying method, Soxhlet extraction method, micro -Kjeldahl method and amino acid determination method recommended by national standard GB 5009.124 -2016. The results showed that the initial moisture content of the chest muscles and leg muscles of the three groups of Jingyuan chickens with different feather colors was 71.10%, 70.35%, 70.69% and 72.14%, 70.13%, 72.08%, respectively, and no significances were observed (P>0.05). The highest fat content in the chest muscles and leg muscles was observed in the black-feathered Jingyuan chickens, which was 2.19% and 3.12%, and the lowest was observed in the white-feathered ones. The highest protein content (24.30%) in the chest muscles was observed in the linen-feathered Jingyuan chickens, followed by the white-feathered ones and black-feathered ones. No significant difference in protein content of the leg muscles was found between the three groups (P> 0.05). There was no significant difference in meat amino acid content between the three groups (P >0.05). The content of glutamate in the chest muscles and leg muscles was the highest, followed by aspartic acid, lysine, leucine and arginine. The linen -feathered Jingyuan chickens had the highest contents of essential amino acid and total amino acid in chest muscles compared to the other two groups. While the highest content of essential amino acid in leg muscles was observed in the linen-feathered Jingyuan chickens, the highest content of total amino acid was found in the white-feathered ones. Our results may have referential value for consumers when purchasing Jingyuan chicken.
