Qualidade de ovos refrigerados sob diferentes locais de armazenamento

Abstract

The objective was to evaluate the quality of eggs from a commercial farm stored under different storage locations. After laying, 90 eggs were collected from ISA Brown laying hens. All eggs were identified and randomly distributed in cardboard trays, with 30 analyzed on the day of collection and at room temperature, 30 stored in the refrigerator door and 30 stored on the refrigerator shelf, analyzed after 15 days. The randomized design in a 3X1 factorial scheme, with 3 types of storage and 1 evaluation period. The variables analyzed were: Egg weight, Haugh Unit, % of shell, white and yolk, white and yolk index and shell thickness. The values of egg weight, % of white, % of shell and yolk index showed no significant difference (P>0.05) in relation to the treatment. The variables % of yolk, UH, shell thickness and yolk index showed a significant difference (P<0.05) in relation to the treatment. It was concluded that there was no difference between storing eggs in the refrigerator door or shelf for a period of 15 days, this result may have been observed by the storage time, changes may occur in longer storage periods.
