Resumo
This study assessed the effect of the cold chain on egg quality in a model simulation of post-washing processing and consumer storage. Post-washed eggs were assigned to 12 groups that simulated the conditions of temporary storage after washing (step 1; 7°C or 25°C for 1 day), transportation (step 2; 7°C or 30°C for 8 h), and selling or storage (step 3; 7°C, 25°C or 30°C for 4 weeks). The freshness and microbial characteristics of the eggs were analyzed for 4 weeks. High-temperature conditions in steps 1 or 2 resulted in reduced quality and more bacteria on eggshells, and this egg quality deterioration worsened after storage for over 2 weeks. In step 3, the quality of the eggs stored at 7°C was maintained during the entire storage, whereas the eggs stored at 25°C had lower quality and broken vitelline membranes in week 4, and the eggs stored at 30°C were spoiled. Eggs should be stored from post-washing until storage by consumers in a cold environment without interruption of temperature control to maintain quality and safety. Consumers must be aware that eggs should be stored at refrigerator temperature.(AU)
