Resumo: | With the objective of characterizing the inner traits of red-winged tinamou (Rhynchotus rufescens) eggs at reproductive phase and evaluate the effects of the storage on quality indicators, a total of 50 eggs were distributed in a completely randomized design and kept at room temperature for 28 experimental days. Average egg weight, Haugh unit, yolk index, width and height of yolk, albumen height, pH of internal components and yolk color were evaluated. Yolk color scores were determined by direct method of chromatic traits (parameters of lightness (L) and chromaticity (a *) (b *)). Assessments were made on days 0, 10, 15, 21 and 28 after laying. During the experimental period there was a reduction (p<0.05) of the Haugh unit and albumen height, albumen pH elevation (p<0.05), reduction (p<0.05) of redness (a*) and increased (p<0.05) yellowness (b*) in the yolk. Throughout the storage time, the average Haugh unit value declined from 84.74 to 41.59, albumen reduced average size into 4.37 mm and became more alkaline (final pH 9.58). The yolk presented itself yellowish, with an increase of 11.51 b* index and a reduction of -1.01 a* index. The other parameters of yolk quality were not affected (p>0.05) by the storage time. It is concluded, therefore, that red-winged tinamous eggs have internal characteristics with great potential for commercial exploitation. However, 28 days of storage at room temperature is enough to affect the albumen quality and yolk color. |

Fueron evaluados peso del huevo, altura de albúmina, ancho y altura de yema, unidad Haugh, índice yema, pH de los componentes internos y color de yema. El color de la yema se determinó mediante el método de caracterización cromática directa [luminosidad (L) y cromaticidad (a*) (b*)]. Las evaluaciones se realizaron los días 0, 10, 15, 21 y 28 inmediatamente después de la puesta. Hubo reducción (p<0.05) en la altura de la albúmina y en la unidad Haugh, aumento (p<0.05) en el pH de la albúmina, disminución (p<0.05) en la intensidad del rojo (a*) y aumentar (p<0.05) en la intensidad del amarillo (b*) en la yema. El valor de la unidad Haugh disminuyó de 84.74 a 41.59, la albúmina disminuyó en 4.37 mm y se volvió más alcalina (pH final 9.58). La yema mostró un color más amarillento, con aumento de 11,51 índice b* y reducción de -1,01 índice a*. Los otros parámetros de calidad de la yema no fueron influenciados (p>0.05) por el tiempo. Se concluye, por tanto, que los huevos de perdiz brasileña tienen características internas con gran potencial de explotación comercial. Sin embargo, 28 días de almacenamiento a la temperatura ambiente son suficientes para afectar la calidad de la albúmina y el color de la yema.Com o objetivo de definir as características internas e verificar o efeito do armazenamento sobre os ovos de perdizes brasileiras (Rhynchotus rufescens), foram avaliados um total de 50 ovos, distribuídos em delineamento inteiramente casualizado e mantidos em temperatura ambiente por 28 dias. Foram avaliados o peso médio dos ovos, altura de albúmen, largura e altura de gema, unidade Haugh, índice de gema, pH dos componentes internos e coloração de gema crua. A coloração da gema foi determinada pelo método direto de caracterização cromática (parâmetros de luminosidade (L) e cromaticidade (a*) (b*)). As avaliações ocorreram nos dias 0, 10, 15, 21 e 28 após a postura. Ao longo do período experimental, houve redução (p<0,05) da altura de albúmen e da unidade Haugh, elevação (p<0,05) do pH de albúmen, diminuição (p<0,05) da intensidade de vermelho (a*) e aumento (p<0,05) da intensidade de amarelo (b*) na gema. O valor médio da unidade Haugh diminuiu de 84,74 para 41,59, o tamanho do albúmen reduziu em média 4,37 mm e tornou-se, ainda mais alcalino (pH final 9,58) e a gema apresentou uma coloração mais amarelada, com aumento de 11,51 índice b* e redução de -1,01 índice a*, ao final dos 28 dias de armazenamento. Os demais parâmetros de qualidade da gema não foram influenciados (p>0,05) pelo tempo. Conclui-se, portanto, que os ovos de perdizes brasileiras possuem características internas com grande potencial de exploração comercial.
