Egg quality assessment at different storage conditions, seasons and laying hen strains

open access: yes, 2017
Eggs are one of nearly perfect protein foods, offering nutrients of great biological value. However, during storage, egg albumen and yolk components may alter and deteriorate egg quality. Therefore, the aim of this work was to assess egg quality during 9-
