摘　　要：本研究分别检测安吉竹林鸡胸肌和腿肌中的肌苷酸、脂肪、水分和水解/游离氨基酸的含量并与白羽肉鸡进行比较分析。结果显示,安吉竹林鸡胸肌和腿肌的肌苷酸含量分别为1324.55和1578.23 mg·kg^(-1),脂肪含量分别为1.21%和2.38%,胸肌和腿肌的水解氨基酸总量分别为22.94%和19.06%,其中必需氨基酸总量分别为9.28%和7.40%,支链氨基酸总量分别为4.53%和3.59%,腿肌中牛磺酸含量为1.771 mg·kg^(-1),胸肌中鹅肌肽和肌肽含量分别为12518和3711 mg·kg^(-1)。以上氨基酸指标均为安吉竹林鸡高于白羽肉鸡,说明安吉竹林鸡的胸肌和腿肌比白羽肉鸡具有更为丰富的肌苷酸、肌内脂肪和氨基酸含量,风味更加鲜美、营养更为丰富。本研究为揭示安吉竹林鸡营养价值评价提供数据支持,同时为安吉竹林鸡高品质风味和营养水平提供理论依据。This study detected the contents of inosinic acid,fat,water and hydrolyzed amino acids/free amino acids in the chest and leg muscles of Anji Zhulin chicken and compared them with white feathered broiler chickens.The results showed that the inosinic acid content of the chest and leg muscles of Anji Zhulin chicken was 1324.55 and 1578.23 mg·kg^(-1),respectively,and the fat content was 1.21% and 2.38%,respectively.The total amount of hydrolyzed amino acids in the chest and leg muscles was 22.94% and 19.06%,respectively,of which the total amount of essential amino acids was 9.28% and 7.40%,and the total amount of branched-chain amino acids was 4.53% and 3.59%,respectively.The taurine content in the leg muscles was 1.771 mg·kg^(-1),and the anserine and carnosine content in the chest muscles were 12518 and 3711 mg·kg^(-1),respectively.The above amino acid indicators were higher in Anji Zhulin chickens than in the white feathered broiler chickens,indicating that the chest and leg muscles of Anji Zhulin chickens had richer contents of inosinic acid,intramuscular fat,and amino acids compared to white feathered broiler chickens,with a more delicious flavor and richer nutrition.This study provides data support for revealing the nutritional value evaluation of Anji Zhulin chicken,and also provides theoretical basis for high-quality flavor and nutritional level of Anji Zhulin chicken.
