Caracterização sensorial de ovos de codornas alimentadas com dietas modificadas

Abstract

The eggs are a reliable source of many compounds, such as vitamins, mineral, and proteins. That is the reason why their consumption has been increasing significantly, mainly quail eggs. Descriptive sensorial analysis, which has a pre-defined terminology for the description of the sensorial perceptions, can be considered the first step in the characterization of a nutritious product. Due to the lack of information on the sensorial characterization for quail eggs, the objective of this work was to evaluate the flavor and aroma of these eggs, whose birds were fed diets containing semi-purified oil of fish and the solid fraction of the chemical silage of fish residues. Firstly, the sensorial team was selected and trained, the terminology for quail eggs was surveyed, and the evaluation of different samples was carried out. 10 judges were selected for flavor evaluation and 10 for aroma analyses. Based on the survey of terms, four different groups were described: sweet, farinaceous, oleaginous, and penetrating. It was verified that the diet of the birds can influence in the sensorial characteristics of the quail eggs. Interference of some favors and aroma of higher intensity was observed. The solid fraction of the chemical silage of fish provides less sensorial modifications than the commercial semi-purified fish oil; when the silage has antioxidants, it does not affect the aroma and flavor of the eggs.
