Abstract
The aim of this study was to evaluate the effect of storage temperature and storage period on the external and internal quality of commercial white eggs. A total of 375 extra eggs of commercial white laying hens of the Hy-line line were allocated in a completely randomized design in a 2 x 7 factorial scheme (temperature x storage period), totaling 14 treatments with five replicates of three eggs each. The treatments were room temperature (26.5oC) and refrigerated (11oC) and seven storage periods (0, 5, 10, 15, 20, 25, and 30 days). There was an interaction (P<0.05) between the factors evaluated for percentage of albumen and yolk, Haugh unit, yolk index and raw yolk color. A reduction in the internal quality of the eggs was observed throughout storage at room temperature compared to refrigerated eggs. Weight loss of the eggs increased in a quadratic manner (P<0.05) and specific gravity decreased linearly (P<0.05) with increasing storage period. The weight loss was intensified at room temperature. In conclusion, white eggs stored at room temperature show marked quality losses, mainly during storage for up to 30 days. Eggs kept under refrigeration can be stored for up to 20 days without changes in internal quality.
