Qualidade interna de ovos comercializados na feira livre no município de Viçosa-AL

Abstract

Eggs are considered high nutritional quality foods, but exposure to high temperatures, solar radiation and storage time can affect their qualitative characteristics. The objective was to evaluate the internal quality of eggs sold at a street market in the municipality of Viçosa - AL. For the analyses, 48 eggs were collected from three stalls at the free fair in the municipality of Viçosa - AL. The eggs were identified, weighed and kept at room temperature. The design used was completely randomized in a 3x4 factorial scheme (3 stalls x four storage periods (zero, seven, 14 and 21 days)), with 4 replications per treatment, with the egg considered as the repetition. The analyzed variables were performed at the end of each storage period, that is, 0; 7; 14 and 21 days of storage, and consisted of: weight of eggs, albumen and yolk; Haugh unit; yolk color; yolk and albumen pH; and albumen and yolk index. Statistical analyzes of the variables studied were performed using the SAEG program - System for Statistical Analysis, version 9.1, and means were compared using the Scott- Knott test at 5% probability. There was a statistical difference for egg weight and yolk color of eggs sold at different stalls in the street market (p<0.05), but there was no significant effect (p>0.05) for Haugh unit, index and pH of yolk and albumen, egg, yolk and albumen weight and yolk color. The eggs sold at different stalls at the street market, stored for up to seven days, maintain a high quality standard, and when stored for seven to 21 days, maintain a low quality standard.
