Certification of Grass-fed Quality Characteristics of Beef Based on Small Molecule Markers

  • Technology Readiness Level: 2


Researchers at Purdue University and the University of Sao Paulo have developed a method to determine the type of feed provided to the cattle. Grass-fed beef has been recognized as healthier than grain-fed beef. However, there has been no optimum way to independently validate the grass-fed claim. The Purdue and Sao Paulo researchers’ method uses a lipid panel coupled with mass spectrometry to identify the metabolized products of grass and grain, allowing determination of whether the cows were fed grass or grain in finishing. This technology allows for a fast and accurate approach to determine the beef quality and meet certification requirements, reducing costs and risk of adulteration.




  • Rapid (<2 minutes) and on-site analysis
  • Increases consumer confidence
  • Voids certification costs and adulteration

Potential Applications

  • Validation feed composition for cattle
  • Beef quality-control
  • Beef certification tool
