235 Animal Production and Carcass Traits Affect Meat Quality and Flavor Through Metabolomics

Abstract Untargeted metabolomics focuses on the detection of as many groups metabolites possible to obtain patterns or fingerprints biological phenomena. Hundreds even thousands can be measured, utilizing advanced chemistry techniques such high-performance liquid chromatography – quadrupole time flight (HPLC-qTOF). Statistical analyses are utilized narrow number from just those that statistically impactful applied treatments. This smaller compounds (100 200) may then analyzed using various multivariate approaches identify influenced by When analyzing serum either Angus Brahman cattle were segregated into three temperament treatments based chute scores, differential upregulation was found between two breed types and scores. It appears in cattle, most temperamental had significantly upregulated according heatmap, while showed downregulated individual animals both Intermediate Temperamental In a separate study illustrate impact meat quality, 18 USDA Select Choice strip loins collected aged for 10 20 d post-processing. Furthermore, steaks each quality grade aging treatment cooked 63, 71, 80oC internal temperature. Samples interior steak excluded exterior seared surface analyzed. Principal Components Discriminant Analysis significant metabolites, all combinations within evenly split side vertical centerline with Component 1 (50.5%) pulling apart. particular, higher temperatures pulled furthest Metabolomics is relatively new but effective technology determining cause effect commonly-known factors quality.
