The interest in carotenoids results from their importance in human nutrition. Particularly, lutein and zeaxanthin play a vital role in the process of seeing, as well as in the lifestyle disease prophylaxis. The objective of the study was to compare the content of lutein in eggs laid by hens from a diversified raising system (cage, bedding, and free-range system) and to sensory assess the eggs under analysis. The highest content of lutein was determined in eggs laid by hens kept in a free-range system (over 50% on average compared to other groups). These eggs were also emphasised in the sensory panel as those with the best taste (4.9) and aroma (4.8). The eggs, laid by hens raised in a poultry farming system and enriched with polyunsaturated fatty acids and vitamins A+E, were characterized by the lowest content of lutein (0.21mg/egg). The standard material, obtained from laying hens raised in a commercial farm, was characterized by the highest egg yolk coloration (14.8) and, at the same time, by a high level of carotenoid determined (0.37mg/egg).
