Abstract
Vitamin A deficiency has been characterized as a public health issue in developing countries. Otherwise, an intake of large doses of vitamin A may cause toxic and teratogenic effects. This study analyzed the effect of freezing procedure on the retinol contents in quail liver by means of high performance liquid chromatography (CLAE). It was also evaluated the contribution to dietary intake in children ranging from 1 to 8 years old, men and women. The average contents of retinol found in the fresh and frozen samples were 6145.7 μg/100g and 5105.5 μg/100g, respectively. The freezing process on the liver caused a significant reduction on retinol contents, with a loss of 17%. Concerning the retinol dietary reference intakes (DRI) for children from 1 to 3 years old and from 4 to 8 years old, one quail liver, which is equivalent to 6 g. provides 123% and 92% of retinol, respectively, showing that the consumption of one quail liver exceeds the limits of daily intake in children from 1 to 3 years old. In adults, the quail liver provides 41% of the required amount to men and 52% to women. This product shows to be a suitable source of vitamin A.
