Abstract

This study evaluated the concentrations of retinol in the yolks of quail and chicken boiled eggs, and they were correlated with the vitamin A intake recommendations for children aged from 1 to 8 years. The samples were analyzed by means of High Performance Liquid Chromatography. The mean values of retinol found in the yolks of the quail and chicken boiled eggs were 636.6 ± 32.7 and 379.1 ± 30.8 μg/100 g of yolk, respectively. The retinol concentration in quail egg was found to be significantly higher than that of chicken egg (p < 0.0001). In addition, it was found that the consumption of a 15 g-portion of egg corresponded to five quail egg yolks or to one chicken egg yolk; then, they supplement 32% and 19% of the daily retinol recommendations for children aged from 1 to 3 years, respectively, and 24% and 14% for children aged from 4 to 8 years, respectively. Therefore, both kinds of eggs are a good source of vitamin A.
