The internal and external quality parameters of the egg are indicators of the freshness state that it presents. The effect of time on the quality of the commercial egg stored on the shelf was evaluated. 120 eggs from the Isa Brown and HyN Brown Nick genetic lines were used, divided into two groups (group A and group B). The variables were measured every three days until day 28 of the egg’s age. Weight, haugh units, yolk pigmentation, shell thickness, yolk index, albumin and yolk pH and visual inspection were analyzed. Significant differences were observed in (p> 0.05) in most of the variables analyzed during the study time. Both groups showed a decrease in egg weight (-3.1 g group A and 3.8 g group B), haugh units (-26.2 g group A and -34.7 g group B), yolk index (-0.34% group A and -0.36% group B), visual inspection (-6 points group A and 3.7 points group B), yolk pigmentation (- 2.1 group A and -1.4 group B) and albumin pH (-1 group A and -0.5 group B); after 28 days of storage. As for the yolk pH, it did not show significant differences (p> 0.05), the values remained during the study. The environment influenced the quality parameters of the egg, reducing its freshness level, except for the yolk Ph, which had a lower degradation process.
