Authenticating wild rabbit meat is crucial due to fraudulent labeling. A new elemental metabolomics method using ICP-MS effectively distinguishes wild rabbit meat from other meats using unique elemental signatures.

Area of Science:

  • Food Science
  • Analytical Chemistry
  • Metabolomics

Background:

  • Accurate meat labeling is vital for consumer information and product integrity.
  • Game meat, including wild rabbit, is susceptible to fraudulent labeling due to its higher commercial value.
  • Distinguishing wild game meat from farmed or domestic alternatives is a significant challenge.

Purpose of the Study:

  • To develop and validate a novel method for authenticating wild rabbit meat.
  • To identify reliable elemental markers for distinguishing wild rabbit from non-wild rabbit meat.
  • To assess the efficacy of elemental metabolomics in combating fraudulent meat labeling.

Main Methods:

  • Elemental analysis utilizing rapid ultra-trace multi-element measurement.
  • Inductively coupled plasma mass spectrometry (ICP-MS) for precise elemental quantification.
Keywords:

  • Application of elemental signatures as biomarkers for meat authentication.

    • Main Results:

    • The developed elemental metabolomics method demonstrated high accuracy in discriminating wild rabbit meat.
    • Specific elemental signatures, including rare earth elements and other trace elements, proved effective in differentiating meat types.
    • The method successfully identified unique elemental profiles characteristic of wild rabbit meat.

    Conclusions:

    • Elemental metabolomics offers a robust approach for the authentication of wild rabbit meat.
    • Trace element signatures, particularly rare earth elements, serve as reliable markers for game meat verification.
    • This method provides a valuable tool to combat fraudulent labeling in the meat industry and ensure product authenticity.
