p-values: Diet < 0.0001; Storage period < 0.001; Interaction (diet × storage period) = 0.002.

Standard error of the mean for TBARS = 0.045.

^{a, b, c}Means in the same row with different letters differ according to Tukey test (p < 0.05) and express the effect of the diet.

^{A, B, C, D, E}Means in same row with different capital letters differ by Tukey test (p < 0.05) and express the effect of the period of storage.
