The global egg market is experiencing significant growth, indicating a rising
consumer interest in eggs as a valuable source of high-quality protein, fats, essential
vitamins and minerals. Ensuring the quality of table eggs poses challenges for producers and
researchers seeking to standardize quality and explore functional food opportunities. The
study provides an overview of factors influencing table egg quality, focusing on pre- and
post-laying determinants. Egg weight, trait crucial for consumer choice, is influenced by
multigenerational breeding efforts and laying hen origin. It is also affected by the laying
management practices and environmental conditions, with varying effects reported in
scientific reports. The strength of eggshell, predominantly composed of calcium carbonate,
is essential for protection but decreases with hen age, necessitating additional mineral
supplementation. Shell cleanliness and colour (affected by genotype) influence consumer
preferences regionally. Albumen, constituting over 60% of an egg's weight, serves as
protection and hydration for the yolk and embryo. Its dense fraction indicates the egg
freshness. Yolk, rich in essential nutrients, varies in proportion and colour, influenced by
genotype, environmental factors, and dietary pigments. Consumer yolk colour preferences,
often influenced by stereotypical beliefs, contribute to regional differences in selection.
This drives research efforts aimed at improving egg quality, safety, and ethical production
standards, while also addressing welfare concerns. With a growing emphasis on health and
sustainability among consumers, future research is expected to prioritize meeting these
expectations while catering to diverse preferences.
