There was no aging method effect (P>0.05) on WBSF (Table 1). Similarly, Oreskovich et al. (1988),and Parrish et al. (1991)found no effects of VAC and DRY aging on WBSF. Ahnström et al. (2006)and De Geer et al. (2009)studied the effects of DRY aging and SB aging on WBSF of strip loin steaks and reported no effect (P>0.05) of aging methodon WBSF. Inour study, WBSF increased (Pb0.0001) as endpoint temperature increased. George-Evins (1999), Pohlman, Dikeman, Zayas, and Unruh (1997); and Obuz et al. (2003)similarly reported higher WBSF with higher endpoint temperature for the Longissimus lumborum, which could be explained by increased myofibrillar and sarcoplasmic protein denaturation and/or coagulation at a higher temperature. Similarly, Obuz et al. (2004)reported a trend for Longissimus lumborum steaks from Choice and Select quality grade to have higher WBSF with higher end-point temperatures.
