BACKGROUND: Of the 18 043 bird species, the eggs of only hen and quail are generally available to consumers. Thus people are deprived of the opportunity to benefit from the huge diversity of eggs offered by nature. Poultry eggs can vary in their color of albumen and yolk, smell, taste and texture. In this study, sighted and blind people were employed for sensory evaluation with the aim of determining the preferences of consumers toward hard-boiled and scrambled eggs of different species of birds, and whether the appearance of these eggs has an effect on the perception of other sensory impressions.
RESULTS: Sighted people differently evaluated the texture of both boiled and scrambled eggs as compared with blind people. This was mainly because blind people largely used their sense of touch for evaluation. All other attributes of boiled eggs were evaluated similarly by both groups of panelists, whereas those of scrambled eggs were evaluated differently.
CONCLUSION: The obtained results unequivocally demonstrated that differences in taste of scrambled eggs when served hot are easier to evaluate than those of boiled eggs. On the basis of ranking by the sensory panel, it was established that eggs of birds belonging to the order Galliformes are more preferred by consumers than those of duck and goose. By contrast, eggs of ostrich and emu are characterized by unfavorable sensory profiles; moreover, the albumen of boiled ostrich eggs has an unsightly appearance. © 2019 Society of Chemical Industry.
