Color, lipid, and protein stability of beef strip loin steak treated with different antioxidants (tocopherol, tertiary butyl hydroquinone, rosemary, or combinations of two of the antioxidants) and packaged in low oxygen (2-5% O2) or high oxygen (80% O2) modified atmosphere packages were studied. The application of tertiary butyl hydroquinone on steaks prior packaging (either in low- or high-oxygen modified atmosphere packages) was significantly effective in minimizing color and lipid oxidation during retail display. Under modified atmosphere packaging (lowor high-oxygen modified atmosphere packaging), oxidation of myoglobin color pigments and lipids were unrelated to beef tenderness.
