The total lutein content was 3385.1 lg/100 g in n-3/lutein enriched eggs, whereas ranged from 1096 to 1347.0 lg/100 g in other eggs .
Storage did not affect the content of lutein. Information on the stability of yolk carotenoids in raw eggs during storage either refrigerated or at room temperature is limited.
Reported that the total carotenoid content in omega-3 fatty acids enriched eggs decreased significantly after 14 days of storage at refrigeration temperature.
Cooking of eggs significantly reduced the quantity of carotenoids and there were no differences between boiling and frying, except for the HW eggs stored for 6 weeks.
