Steaks were thawed for 24 h in a 1°C cooler and then
broiled on Farberware Open Hearth electrical broilers
(Farberware, Bronx, NY). Steaks were turned every 4
min during broiling until an internal temperature of
71°C was reached. Internal temperature was monitored
by a digital thermometer placed in the approximate
geometric center of each steak. Cooked steaks were
cooled to room temperature (≈20°C) before four to eight
cores (1.27 cm) were removed parallel to the longtitudinal
orientation of the muscle fibers. Individual cores
were sheared once on a Warner-Bratzler shear machine.
An average shear force was calculated and recorded
for each steak.
