The aim of this study is to determine the content of total iron (TFe), heme iron (HeFe), zinc (Zn), and copper (Cu) in different cuts of meat and viscera from rabbit. Five young New Zealand rabbits were used in the study. Samples in triplicate were obtained from three meat cuts (foreleg, hind leg, and loin) and from main viscera. TFe, Zn, and Cu concentrations from samples were determined by wet acid digestion followed by atomic absorption spectrophotometry (AAS), while HeFe was determined by acid extraction followed by AAS. Mean TFe, HeFe, Zn, and Cu in meat was 0.83 ± 0.09, 0.56 ± 0.11, 0.95 ± 0.35, and 0.08 ± 0.01 mg/100 g, respectively. TFe content was less than 1 mg/100 g in all meat cuts. Sixty-seven percent of iron content was HeFe. The cut of meat with highest Zn concentrations was the foreleg with 1.33 ± 0.12 mg/100 g. Cu content was low for all meat cuts. TFe, HeFe, Zn, and Cu content in viscera varied greatly. The spleen was the organ with the highest TFe and Zn concentrations (82.79 ± 9.22 mg/100 g and 3.49 ± 0.63 mg/100 g, respectively). Nevertheless, the lungs had the highest concentration of HeFe (5.79 ± 0.90 mg/100 g), accounting for 91% of the total iron. The liver had the highest Cu content (3.89 ± 0.89 mg/100 g). Rabbit meat has low TFe concentration, similar to that of poultry, and most of the iron is HeFe. The amount of minerals in viscera closely depends on their function.
本研究旨在测定兔肉不同部位（前腿、后腿和里脊肉）和主要内脏中铁（TFe）、血红素铁（HeFe）、锌（Zn）和铜（Cu）的含量。研究使用了 5 只年轻的新西兰白兔。从 3 个肉部位（前腿、后腿和里脊肉）和主要内脏中获得了 3 份重复样本。采用湿法酸消解后原子吸收分光光度法（AAS）测定样品中 TFe、Zn 和 Cu 的浓度，采用酸提取后 AAS 法测定 HeFe 的浓度。肉中 TFe、HeFe、Zn 和 Cu 的平均含量分别为 0.83±0.09、0.56±0.11、0.95±0.35 和 0.08±0.01mg/100g。所有肉部位的 TFe 含量均低于 1mg/100g，铁含量的 67%为 HeFe。Zn 浓度最高的肉部位是前腿，为 1.33±0.12mg/100g。所有肉部位的 Cu 含量均较低。内脏的 TFe、HeFe、Zn 和 Cu 含量差异很大。脾脏是 TFe 和 Zn 浓度最高的器官（分别为 82.79±9.22mg/100g 和 3.49±0.63mg/100g）。然而，肺部的 HeFe 浓度最高（5.79±0.90mg/100g），占总铁的 91%。肝脏的 Cu 含量最高（3.89±0.89mg/100g）。兔肉的 TFe 浓度较低，与家禽相似，且大部分铁为 HeFe。内脏中矿物质的含量取决于其功能。
