<p>Natural biopolymer coatings developed to minimize quality deterioration during the storage of table eggs have recently emerged as sustainable and innovative preservation strategies in food technology. This study investigated the effects of an egg albumen-based biopolymer coating on the shell, albumen, and yolk color traits of table eggs stored under ambient conditions. A total of 600 medium-sized table eggs obtained from Bovans White laying hens were used. Eggs were randomly allocated into three experimental groups: an uncoated control group, a washed group coated with an albumen-based biopolymer (W), and a non-washed group directly coated (NW). The coating solution consisted of egg albumen plasticized with glycerol, and stored under ambient conditions (25 °C) for seven weeks. Shell color was determined using 20 eggs per treatment, whereas albumen and yolk color were evaluated in 10 eggs per treatment using a spectrocolorimeter. Data were analyzed by one-way analysis of variance</p><p>followed by Tukey’s multiple comparison test (P<0.05). Although statistically significant weekdependent effects were observed for the L*, a*, and b* color coordinates of the shell, albumen, and yolk, the absence of a consistent increasing or decreasing trend throughout the storage period suggests that these variations were primarily attributable to individual sample variability rather than to the coating treatments. At the beginning of storage, shell L* values were comparable between the Control and NW groups; however, this difference disappeared by the end of the storage period. No significant differences were detected among the experimental groups in albumen or yolk color traits. Overall, the findings indicate that the egg albumen-based biopolymer coating did not adversely affect the natural appearance of egg components or consumer perception and may therefore be considered a natural, sustainable, and environmentally friendly alternative coating material for the storage of table eggs.</p>
