| The objective of this study was to examine the effects of coatings made from Moringa oleifera (MOC) and Gmelina aborea (GAC) seed oils on the internal quality parameters of eggs maintained at room temperature (28–30°C) for four weeks. The assessed egg quality metrics comprised yolk pH, albumen pH, Haugh unit, yolk index, weight loss, and total bacterial count of egg contents. The impact of applying a coating on the weight reduction became evident after a week of storage, with notable disparities (p < 0.05) seen between eggs without a coating (1.46%) and eggs with a coating (0.27-0.31%). For Haugh unit, eggs coated with MOC consistently maintained a grade of “AA” (HU > 72) for the entire storage period. On the other hand, eggs coated with GAC and uncoated eggs showed a decrease in grade quality, transitioning from “AA” to “A” and “B” correspondingly. The eggs covered with MOC showed the highest yolk index of 0.41, followed by the eggs coated with GAC with a yolk index of 0.34. Both values were substantially different (p < 0.05) from the yolk index of uncoated eggs, which was 0.18. The data on egg microbiological quality indicated that the total viable count (TVC) in control eggs was higher and exhibited a statistically significant difference (p < 0.05) compared to that in coated eggs. This study emphasises a sustainable method for maintaining the internal quality and extending the shelf life of eggs stored at room temperature. | |
