Abstract
AbstractThe intramuscular fat (IMF) in beef affects its flavor intensity and attributes, which have a significant impact on palatability. We conducted a sensory evaluation by descriptive analysis, Temporal Check‐All‐That‐Apply, and a chemical analysis of 40 ribeye steaks from Japanese Black cattle to determine the relationship among IMF% and sensory characteristics including dynamic flavor attributes. The increased IMF% of Japanese Black cattle beef had intensified sweet and grilled/roasted flavors and reduced off‐flavor, whereas excessive IMF% resulted in a decrease in water‐soluble precursors of volatile and taste compounds including free amino acid and reducing sugars and weakened the flavor intensities. Beef with IMF% of approximately 40% exhibited strong and long‐lasting sweet and grilled/roasted flavors represented by butter‐ and roasted nut‐like, respectively, and a low perception of off‐flavors represented by gamey, bloody, and grassy. These flavor attributes may be responsible for its high flavor intensity and overall evaluation score, whereas an IMF% of >55% lowered these scores. The excessive IMF% of beef may induce the less palatable sensory characteristics.
