Sensorial characteristics of eggs stored at room temperature under different packing conditions

Abstract

This study evaluated the sensory characteristics of white-shelled eggs, sanitized or not, stored under different packaging conditions at room temperature. There were used 200 eggs, distributed in a completely randomized design in a 3×2×4+1 factorial arrangement, three packaging conditions (PVC film, partial vacuum, partial vacuum with oxygen gas absorber), storage period (7, 14, 21 and 28 days), sanitized or not, and control (fresh eggs), with four repetitions of two eggs, and ten judges. The eggs were visually and olfactorily evaluated in different periods of storage, by Quantitative Descriptive Analysis (QDA) by means of unstructured scales of 9 cm. Partial vacuum condition showed that the eggs were rejected by the external and internal appearance and external odor, especially if not sanitized. In this condition were observed sour smells and opaque egg yolks. In vacuum with O2 sachets absorbers were noted sour smells, especially if sanitized. It can be concluded that eggs packed in PVC film, sanitized or not, showed the best acceptances in all attributes.
