Consumers tend to buy meat based on visual physical characteristics, which are affected by the chemical composition of the meat, and there is very little known about the chemical composition of the meat of giraffe. This study therefore aims to broaden the knowledge base on the chemical composition of giraffe meat, rib bone and liver. Eight different muscles from 15 giraffes were analyzed to determine the chemical composition, yielding an average moisture of 77.2 ± 0.09 g/100 g meat, an average protein of 20.8 ± 0.09 g/100 g meat, an average intramuscular fat (IMF) of 1.4 ± 0.03 g/100 g meat and an average ash of 1.1 ± 0.01 g/100 g meat. There was a significant interaction between sex and muscle for the moisture, protein and ash contents, while only muscle had an effect on the fat content. The mineral content of the bone, liver and muscle was also analyzed, and bone was found to be a rich source of calcium (highest concentration), whilst the liver had the highest concentration of iron. The chemical composition of the giraffe meat was such that it could be classified as lean meat.
消费者倾向于根据肉类的视觉物理特征来购买肉类,而这些特征会受到肉的化学成分影响,然而人们对长颈鹿肉的化学成分知之甚少。因此,本研究旨在拓宽关于长颈鹿肉、肋骨和肝脏化学成分的知识基础。对15只长颈鹿的8种不同肌肉进行了分析,以确定其化学成分,得出肉的平均水分含量为77.2±0.09克/100克肉,平均蛋白质含量为20.8±0.09克/100克肉,平均肌内脂肪(IMF)含量为1.4±0.03克/100克肉,平均灰分含量为1.1±0.01克/100克肉。水分、蛋白质和灰分含量在性别和肌肉之间存在显著交互作用,而只有肌肉对脂肪含量有影响。还分析了骨骼、肝脏和肌肉的矿物质含量,发现骨骼是钙的丰富来源(浓度最高),而肝脏中铁的浓度最高。长颈鹿肉的化学成分使其可被归类为瘦肉。
