Values are given as means±SD from triplicate determinations.
Different letters in the same column indicate significant differences (p<0.05).
CIE L*, lightness; CIE a*, redness; CIE b*, yellowness; (C), Chroma; (H°), hue angle; (ΔE), total color change; (B.I), Browning index; Control, fresh minced beef; Nitrite (100 mg/kg), fresh minced beef with nitrite; NO-Hb (10g/kg), fresh minced beef with nitroso-hemoglobin; LAB, lactic acid bacteria combined such as S. thermophilus, L. bulgaricus, L. casei, and M. enterococcus has five different groups includes; LAB (0:1)=in the absence of LAB and presence of other pathogenic; LAB (1:1)=in the presence of LAB and other pathogenic in the same ratio; LAB (2:1)=in the presence of LAB and other pathogenic, respectively; LAB (3:1)=in the presence of LAB and other pathogenic, respectively; (4:1)=in the presence of LAB and other pathogenic bacteria, respectively.
