Abstract

Dielectric properties of albumen and yolk of eggs were measured at 24degC over the frequency range from 10 MHz to 1800 MHz to monitor quality changes during a 5-week storage period at 15degC. Quality factors such as Haugh unit, yolk index, moisture content and egg weight were also measured during the same period. On average, the Haugh unit, yolk index and egg weight decreased with time indicating quality deterioration. Albumen moisture content increased at first and then decreased after the third week of storage. The opposite trend was observed for the yolk moisture content. Variations of the measured dielectric properties of albumen and yolk with frequency, moisture content, and quality indicators are presented.
