Evaluating Consumer Acceptability And Willingness To Pay For Various Beef Chuck Muscles, A.C. Kukowski, R.J. Maddock, D.M. Wulf, G.L. Taylor Nov 2005

Evaluating Consumer Acceptability And Willingness To Pay For Various Beef Chuck Muscles, A.C. Kukowski, R.J. Maddock, D.M. Wulf, G.L. Taylor

Animal Science Faculty Publications

In-home consumer steak evaluations, followed by centralized laboratory-setting auctions, were used to determine consumer (n = 74 consumers) acceptability and willingness to pay for various beef chuck muscles. The infraspinatus (IF), serratus ventralis (SV), supraspinatus (SS), and triceps brachii (TB) from the beef chuck were evaluated against LM steaks from the rib to determine price and trait differentials. Muscles from USDA Choice, boneless, boxed-beef subprimals were aged 14 d, frozen, and cut into 2.5-cmthick steaks. Consumers received two steaks from each muscle for in-home evaluations of uncooked steak appearance and cooked steak palatability. After in-home evaluation of steaks, consumers participated ...


Evaluating Consumer Acceptability Of Various Muscles From The Beef Chuck And Rib, A.C. Kukowski, R.J. Maddock, D.M. Wulf Feb 2004

Evaluating Consumer Acceptability Of Various Muscles From The Beef Chuck And Rib, A.C. Kukowski, R.J. Maddock, D.M. Wulf

One hundred thirty-eight consumers evaluated steaks from the complexus (CX), infraspinatus (IF), serratus ventralis (SV), supraspinatus (SS), and triceps brachii (TB) from the wholesale beef chuck; the deep pectoral (DP) from the wholesale brisket; and the longissimus thoracis (LT) from the wholesale rib. The LT was used as a reference for comparison to the other muscles. Ten USDA Choice and ten USDA Select boneless boxed beef subprimals were used for each muscle. Subprimals were aged 14 d from box date, frozen, and cut into 2.5-cm-thick steaks. Consumers rated the IF highest (P < 0.05) for overall like, tenderness, juiciness, and flavor, and assigned it the highest (P < 0.05) price/0.45 kg. The TB also was rated higher (P < 0.05) than the LT for overall like, tenderness, juiciness, flavor, and price/0.45 kg. The SV and CX were rated as being similar (P < 0.05) to the LT for overall like, tenderness, juiciness, flavor, and price/0.45 kg. Consumers rated the SS lower (P < 0.05) than the LT for tenderness, juiciness, flavor, and price. The DP was rated as the toughest, driest, and blandest (P < 0.05), resulting in assignment of the lowest (P < 0.05) price/0.45 kg. Differences in palatability ratings due to quality grade were found for several muscles; USDA Choice SV and SS were rated higher (P < 0.05) for overall like, tenderness, and juiciness than USDA Select SV and SS. For the IF, USDA Choice was rated higher (P < 0.05) for tenderness and juiciness than USDA Select. The USDA Choice TB was rated higher (P < 0.05) for juiciness, and the USDA Choice DP was rated higher (P < 0.05) for overall like, than their USDA Select counterparts. Tenderness, juiciness, and flavor ratings were correlated with overall like ratings (r = 0.84, 0.77, and 0.76, respectively) and with price (r = 0.73, 0.70, and 0.68, respectively). These results indicate the IF, TB, SV, and CX were acceptable, whereas and the SS and DP were unacceptable as steaks.


Relationships Among Glycolytic Potential, Dark Cutting (Dark, Firm, And Dry) Beef, And Cooked Beef Palatability, D.M. Wulf, R.S. Emnett, J.M. Leheska, S.J. Moeller Jul 2002

Relationships Among Glycolytic Potential, Dark Cutting (Dark, Firm, And Dry) Beef, And Cooked Beef Palatability, D.M. Wulf, R.S. Emnett, J.M. Leheska, S.J. Moeller

One hundred beef carcasses were selected at three packing plants and were used to determine the relationship between glycolytic potential (GP) and dark, firm, and dry (DFD) beef and to determine the effects of DFD status and GP on cooked beef palatability. Eight individual muscles were excised from one hindquarter of each carcass at d 7 postmortem: longissimus lumborum, psoas major, gluteus medius, tensor fasciae latae, rectus femoris, semimembranosus, biceps femoris, and semitendinosus. Ultimate pH, colorimeter readings, and Warner-Bratzler shear force were determined for all eight muscles at d 7 postmortem. A ninemember trained sensory panel evaluated cooked longissimus lumborum ...
