^¹Data are expressed as means ± standard deviations. Information was collected in 12 eggs per treatment. Statistical models included the effects of treatments (P < 0.001), storage periods (P < 0.001), and interaction (treatments by storage periods, P < 0.001).

^a-dMeans in the same row with different lowercase letters are significantly different (P < 0.001).

^A-FMeans in the same column with different capital letters are significantly different (P < 0.001).
