Abstract


The effects of hen age, storage time and packaging with stretch film applications to the internal and external egg quality of table eggs were investigated. A total of 1680 table eggs were used and collected with two commercial layer stocks (Lohmann White ) 28 and 80 weeks old age. A half of the table eggs packaged with stretch film and all eggs were stored 0, 15, 30 and 45 days at 22 ºC ve 45 % RH . Egg weight, shape index, albumen index, fracture strength, albumen index, yolk index Hauhg unit, yolk color, shell weight, shell thickness, shell weight per unit surface of shell and shell density were examined in the study. Egg weight, egg weight loss, shell weight, albumen index, yolk index, Haugh unit, shape index, shell strength, shell thickness, shell density values were found as higher in the young hen flocks’ eggs. Egg weight loss, shell strength, shell thickness, egg weight, shell density increased and egg weight, albumen index, yolk index and Haugh Units and shell weigh decreased as storage time increased. Packaging eggs with stretch film reduced the internal quality losses resulted from prolonged storage.
