摘　　要：通过对三都柳源香鸡鸡肉质进行营养成分的分析,评价其营养价值。测定三都水族自治县柳源香鸡鸡肉的水分、灰分、蛋白质、粗脂肪、脂肪酸、氨基酸和维生素的含量。结果表明:三都柳源香鸡鸡肉营养成分(鲜质量百分比)为水分含量68.97%、蛋白质18.71%、脂肪8.75%、灰分1.125%。鸡肉中含有16种氨基酸,除色氨酸外其余7种人体必需氨基酸俱全,占总氨基酸的35.81%。苏氨酸、缬氨酸、蛋氨酸为限制性氨基酸。柳源香鸡肉中脂肪酸以不饱和脂肪酸为主,占总脂肪酸的65.7%,且油酸和亚油酸的含量最高,分别为32.99%和20.14%。VD和VB的含量较通常肌肉平均值高。说明柳源香鸡具有良好的营养价值,利于人体吸收,味美质高。In this paper, the nutritional composition of Liuyuan chicken, a local breed in Sandu Shui Autonomous County, was analyzed to evaluate its nutritional value. The contents of water, ash, protein, crude fat, fatty acids, amino acids and vitamin in the breast and thigh muscles of the chicken breed were measured. The results showed that Liuyuan chicken contained 68.97% water, 18.71% protein, 8.75% fat and 1.125% ash （all the values were on a fresh weight basis）. A total of 17 amino acids were found, including all the essential amino acids except Iryptophan, which accounted for 35.81% of the total amino acids, 4 kinds of tasty amino acids with a content of 641.46 mg/100 g of freeze-dried samples, and three limiting amino acids such as threonine, valine and methionine. Unsaturated fatty acids were prominent in Liuyuan chicken, accounting for 65.7% of the total fatty acids. Oleic acid and linoleic acid showed the highest content, reaching 32.99% and 20.14%, respectively. Liuyuan chicken exhibited higher average contents of VD and VB than other breeds. In conclusion, Liuyuan chicken has outstanding nutritional value, good ease of absorption by the human body and high palatability.
