AMSA Announces Symposium Speakers on ‘What is New in the Science of Meat Quality’

Jul 09, 2020

AmericanFoodsGroupThe American Meat Science Association (AMSA) is pleased to announce, Dr. JF Hocquette and Dr. Ranjith Ramanathan will be the featured speakers in the concurrent symposium entitled What is New in the Science of Meat Quality” on Tuesday, August 4, 2020 during the 66th International Congress of Meat Science and Technology (ICoMST) and the AMSA 73rd Reciprocal Meat Conference (RMC) exclusively virtual meeting. This session will be sponsored by American Foods Group.

The featured presentations include:

Jean-François HOCQUETTEResearch in beef tenderness and palatability in the era of big data: In recent years, research has focused on predicting the palatability of beef using muscle biochemical traits, their genetic markers, and other biomarkers. In these approaches, a precision definition of the variable to predict (tenderness assessed by panelists, untrained consumers, or shear force), as well as repeatability of the measurements are crucial to compare results across labs and for enabling consolidation of separate datasets, creating a significant data resource for the derivation of more robust predictive models, and more rigorous validation testing. Research was focused on tenderness, since flavour and other components of palatability are difficult to replicate through laboratory approaches. This “big data” approach would require careful definition of trait ontologies and transparent principles for data sharing, management, and contributor recognition. As in other scientific fields, meat science researchers should improve the Findability, Accessibility, Interoperability, and Reuse of data (known as the FAIR principles). Furthermore, with the rapid evolution of new measurement technologies, the traits that they measure must be consistently described, enhancing our ability to integrate these new measurements into existing description systems. For beef, strategic choices have to be made in order to consider real consumers’ expectations, not well estimated correctly by lab approaches. This strategy has been successfully developed in Australia, which set up the “Meat Standards Australia” grading scheme, now partly adopted by the local beef industry. In this session, Dr. JF Hocquette, Research Scientist for the French National Institute for Agricultural Research, will discuss the ambitions of the International Meat Research 3G Foundation is to develop beef ontology, to set up an international database with a huge number of consumers’ scores related to beef palatability and collected according to standard protocols. Another goal of the foundation is to support the beef industry by offering an international predictive model of beef palatability, flexible enough to take into account any local livestock characteristics or any regional consumer specificity. This approach is supported by the United Nations Economic Commission for Europe (UNECE), which is promoting development of regulations and norms, technical cooperation and exchange of best expertise and practices. This will substantially improve the transparency of data flow and price signaling between all participants of the value chain, from beef producers through to consumers at retail.

Ramanathan220Recent updates in meat color research: Integrating traditional and high-throughput approaches: Deviation from bright-cherry red color of meat results in less consumer acceptance and discounted in the value chain. In this presentation, Dr. Ranjith Ramanathan, Associate Professor of Meat Science and Leo and Kathy Endowed Research Professorship at Oklahoma State University, will focus on both fundamental and applied approaches to understand the effects of pH on biochemical changes, oxygen diffusion, and its impact on meat color. Recent updates utilizing high-throughput omics approaches to elucidate the biochemical changes with high-pH will be discussed. Further, emphasis will be given to improve the appearance of dark-cutting beef using active packaging and enhancement strategies.

The 66th ICoMST and AMSA 73rd RMC will be held August 3-6, 2020 online in the virtual format. For more information please visit: www.icomst2020.com or contact Deidrea Mabry 1-800-517-AMSA ext. 12.
