The purpose of dry aging is to develop novel favors and other sensory characteristics different from wet aged meat. However, leaving meat exposed to air for an extended period of time can have negative effects on meat quality. As the meat is exposed to oxygen for an extended period of time, lipids are oxidized resulting in compounds that negatively affect favor. In this study, oxygen concentration was regulated along with time, temperature, humidity, and air flow. The purpose of oxygen regulation was to determine the effect of oxidation on the quality, specifically flavor preference, of dry aged meats. Sensory analysis via untrained panelists detected no flavor differences between traditionally dry aged meat and meat dry aged in anaerobic conditions, despite anaerobic dry aged samples having lower lipid oxidation values. Further sensory analysis via highly trained panelists is being conducted to determine if lipid oxidation affects dry aged beef flavor.
