Fig. 2.

Changes in glycogen content (A), lactate content (B), glycolytic potential (C), and pH (D) of bovine muscle when stored at 4 °C for 0.5, 2, 6, 12, 24, 36, and 48 h after treatment with 200 μM H₂O₂ (H₂O₂ group) and saline (control group). Data were expressed as mean ± standard error (n = 6). The capital letters and lowercase letters represent the significant difference (P < 0.01) in the same group at different times, respectively. * (P < 0.05) and ** (P < 0.01) represent the difference between the two groups at the same time point, respectively.
