Accurate labelling of meat (e.g. wild versus farmed, geographical and genetic origin, organic versus conventional, processing treatment) is important to inform the consumers about the products they buy. Meat and meat products declared as game have higher commercial value making them target to fraudulent labelling practices and replacement with non-game meat. We have developed and validated a new method for authentication of wild rabbit meat using elemental metabolomics approach. Elemental analysis was performed using rapid ultra-trace multi-element measurement by inductively coupled plasma mass spectrometry (ICP-MS). Elemental signatures showed excellent ability to discriminate the wild rabbit from non-wild rabbit meat. Our results demonstrate the usefulness of metabolic markers -rare earth signatures, as well as other trace element signatures for game meat authentication.

通过稀土元素指纹识别野味肉认证

肉类的准确标签（例如野生与养殖、地理和遗传来源、有机与常规、加工处理）对于告知消费者他们购买的产品很重要。被声明为野味的肉类和肉类产品具有更高的商业价值，使其成为欺诈标签行为和替代非野味肉类的目标。我们开发并验证了一种使用元素代谢组学方法鉴定野兔肉的新方法。通过电感耦合等离子体质谱法 (ICP-MS) 使用快速超痕量多元素测量进行元素分析。元素特征显示出极好的区分野兔和非野兔肉的能力。我们的结果证明了代谢标志物——稀土特征的有用性，
