Abstract
  1. Carcass cuts, chemical composition, colour, textural parameters, fatty acid and amino acid profiles, macro- and micromineral content and sensory properties of breast and drumstick meat from 10 month old common pheasant produced in an extensive rearing system were analysed. 2. Breast muscle was characterised by a high concentration of protein (254 g/kg), low content of intramuscular fat (1.3 g/kg), considerable amount of Fe-haeme (4.9 mg/kg) low shear force (1.96 kg/cm(2)) and hardness (4.07 kg/cm(2)). 3. The main drumstick characteristics were 222 g of protein/kg, 4.0 g of intramuscular fat/g and a significant higher cholesterol concentration compared to that of breast (7.7 vs. 2.9 g/kg). 4. Saturated, monounsaturated and polyunsaturated fatty acid mean values for both muscle types were approximately 34.5%, 43.3% and 24.2% of total fatty acid methyl esters, respectively, and n-3 content in breast was significantly higher (3.21% vs. 1.65%). Significant differences were found between the three tissues (breast, drumstick and subcutaneous fat). 5. Large differences in the amino acid profile between breast and drumstick were detected, especially in the non-essential fraction. The main essential amino acids were lysine and leucine, whereas aspartic and glutamic acids were the most important non-essential amino acids. 6. There were significant differences between muscle types in the mineral content with regard to iron, magnesium, sodium and zinc. Pheasant meat is a good nutritional source of iron as 100 g of drumstick may provide 23.6% of the recommended daily amount.
摘要
  1. 对在大规模放养系统中生长的 10 月龄普通雉鸡的胸脯肉和鸡腿肉的屠体切块、化学成分、色泽、质构参数、脂肪酸和氨基酸组成、宏量和微量矿物质含量以及感官特性进行了分析。

  2. 胸脯肉的特点是蛋白质含量高(254 克/千克),肌内脂肪含量低(1.3 克/千克),铁原卟啉(4.9 毫克/千克)含量相当高,剪切力低(1.96 千克/厘米²),硬度低(4.07 千克/厘米²)。

  3. 鸡腿的主要特点是每千克含蛋白质 222 克,肌内脂肪 4.0 克,与胸脯肉相比,胆固醇浓度显著更高(7.7 克/千克对 2.9 克/千克)。

  4. 两种肌肉类型的饱和、单不饱和和多不饱和脂肪酸平均值分别约占总脂肪酸甲酯的 34.5%、43.3%和 24.2%,而胸脯肉中的 n-3 含量显著更高(3.21%对 1.65%)。三种组织(胸脯肉、鸡腿和皮下脂肪)之间存在显著差异。

  5. 胸脯肉和鸡腿的氨基酸组成存在很大差异,尤其是非必需氨基酸部分。主要的必需氨基酸是赖氨酸和亮氨酸,而天冬氨酸和谷氨酸是最重要的非必需氨基酸。

  6. 不同肌肉类型之间的矿物质含量存在显著差异,特别是铁、镁、钠和锌。100 克鸡腿肉可提供 23.6%的推荐日摄入量,是铁的良好营养来源。
