Abstract
Palatability traits of ribeye, strip loin, andtenderloin steaks were evaluated in a bone-in versus boneless scenario. Eatingquality of these cuts was also evaluated in a high quality (upper 2/3 USDAChoice) and a lower quality (USDA Select) product to evaluate the interactionsof marbling level and bone state. Subprimals were collected from both sides of12 beef carcasses per quality grade and aged for 28-d. Product was fabricatedinto 2.5-cm thick steaks and designated for either trained sensory analysis,consumer sensory analysis, Warner-Bratzler Shear Force (WBSF), or fat andmoisture determination. Results from trainedsensory analysis showed bone-in tenderloins and bone-in ribeyes as moreflavorful (P < 0.05) than boneless cuts from the same muscle. Bonestate had no effect (P > 0.05) on trained sensory initial juiciness,myofibrillar tenderness, and overall tenderness scores, or WBSF for any cut.Furthermore, tenderloin samples were rated higher (P < 0.05) bytrained sensory panelists for myofibrillar and overall tenderness than striploin and ribeye steaks, which were similar (P > 0.05). Bone state hadno impact (P > 0.05) on consumer tenderness and flavor ratings forany of the three cuts. But, bone-in strip loin samples were rated juicier andhigher (P < 0.05) overall than boneless strip loin steaks byconsumers. Tenderloin steaks were juicier, more tender, more flavorful, andrated higher overall (P < 0.05) than ribeyes and boneless strip loinsteaks by consumers. Moreover, there were no differences (P > 0.05)between strip loins and ribeyes for flavor liking by consumers and nodifference (P > 0.05) in overall liking rating between ribeyes andboneless strip loin steaks. Overall, bone status had a minimal impact on beefpalatability traits, providing evidence that eating quality is not greatlyimpacted by bone status for any of the cuts evaluated.
