摘　　要：The emergence of safe and functional eggs for consumer acceptance has gained focus.The production of carotenoid-enriched eggs has received attention due to its multifunctional biological properties.Nutritional modification of laying hens’diet can be a strategy to produce such eggs.This review presents the chemistry of carotenoids in nature and eggs,the accumulation process of carotenoids into eggs,and the functions of carotenoids in eggs.Our findings showed that carotenoids can be deposited into the egg and contribute to improving its nutritive value.The biosynthesis,chemical structure,and metabolism pathways of carotenoids lead to the deposition of carotenoids into eggs in their original or metabolized forms.Also,some factors modulate the efficiency of carotenoids in fowls before accumulation into eggs.Carotenoid-enriched eggs may be promising,ensuring the availability of highly nutritive eggs.However,further studies are still needed to comprehend the full metabolism process and the extensive functions of carotenoids in eggs.
