Strip loins from two experiments were used to evaluate effects of feeding dry (DDG) or wet (WDG) distiller's grains on beef color, tenderness, and sensory traits of Holstein steers. In Exp. 1, conducted at the University of Illinois at Champaign-Urbana, dietary treatments consisted of a control whole corn-corn silage diet with soybean meal (SBM) or diets formulated with 12.5% DDG plus urea, 25%...

The objective of this study was to determine the effect of freezing and thawing or freezing and thawing with an additional aging period after frozen storage on the tenderness of longissimus lumborum (LL) and semitendinosus (ST) steaks relative to aged, fresh steaks. Left-side LL and ST (n = 35 each) were obtained from U.S. Select carcasses classified at the grading stand by the U.S. Meat Animal...

The objective of this study was to evaluate processing methods for frozen beef subprimals; the effects of freezing and thawing rates on tenderness, sensory properties, and retail display were evaluated. There were 6 treatments: fresh, never frozen 14 d wet aged (14D); fresh, never frozen 21 d wet aged (21D); blast frozen-fast thawed (BF); blast frozen-slow thawed (BS); conventionally frozen-fas...

Beef top loin steaks from Top Choice (Modest and Moderate marbling), (primarily Small Select (Slight marbling) beef strip loins Texas Non-Texas (Kansas, Nebraska, Colorado) processing establishments were obtained to determine the role of source USDA grade/brand category on consumer sensory panel Warner-Bratzler shear (WBS) evaluations. The number 58 Choice, 54 56 60 52 Select. There × interacti...

The influence of harvest method on proximate composition, protein oxidation, and texture profile beef from Nellore cattle were investigated. Longissimus lumborum (LL) muscles obtained twelve grain-fed carcasses. animals slaughtered after stunning (STU; n=6) or without (WST; 24 hours postmortem, the LL was sliced into 2.54-cm steaks, packed under aerobic conditions, stored at 4°C for nine days. ...

The objective of this study was to evaluate attributes in semitendinosus muscle (ST) associated with tenderness in divergent breeds--Wagyu (W; n = 12), Limousin (L; n = 12), and Wagyu x Limousin cross cattle (WxL; n = 12)--fed two dietary treatments (0 or 6% sunflower oil, DM basis). A randomized complete block repeated measures design with a 3 x 2 factorial arrangement of treatments was used t...

Sodium erythorbate and ascorbic acid were compared as a means to stabilize surface colour of bone-in beef steaks in high-oxygen modified atmosphere (80% oxygen and 20% carbon dioxide). Bone-in strip loins (n=8) were fabricated into 1.9-cm thick steaks, of which both the lumbar vertebrae and longissimus lumborum were topically treated with either ascorbic acid or sodium erythorbate (0, 0.05, 0.1...

Contributions of initial and retained levels of oxygen consumption and reducing capacity to animal variation in color stability were evaluated. Instrumental color values were determined on longissimus steaks (n=257) during 6 d of display. Oxygen consumption (OC), nitric oxide metmyoglobin reduction (NORA), initial metmyoglobin formation (IMF), and post-reduction metmyoglobin (PRM) were measured...

Experimental methods were used to examine consumer willingness-to-pay for steak tenderness in a grocery store setting. When relying on a taste test alone to determine product quality, the participants paid an average premium of $1.23/lb for a tender versus tough steak. Fifty-one percent of the participants were willing to pay an average of $1.84/lb when they had completed a taste test and were ...
