however those containing GSE500
remained slightly higher. Visual brown color of all samples ranged
from 8 to 8.5 at the initiation of the study (Fig. 4b). By month 3, it had
decreased (pb0.05) for all samples; however, samples containing
300 ppm or 500 ppm GSE were slightly more brown (7 to 8) than AAcontaining
samples (about 5). Rojas and Brewer (2007) reported no
differences in visual color due to addition of antioxidants to cooked,
refrigerated beef.
