¹Hedonic scale from 1 to 9, where 1 means dislike extremely and 9 means like extremely.

²Preference was estimate as a coefficient (0 to 1) of how frequently the eggs were selected as the best by the panelists. Values are reported as Least Square means in logit values ± SEM and the probability value in ().

³Abbreviations: BlF, blue-shell farm egg; BrF, brown-shell farm egg; FR, free-range or cage-free eggs; WC, white-shell egg cage system.

⁴Letters a, b, and c in a variable indicate significant differences (P ≤ 0.05), Letters x, y, and z indicate tendencies.
