Abstract: Study on eggs
properties, based on electrical measurement (conductance and capacitance) was
carried out using alternating current signal on frequency variation from 10 Hz
to 100 kHz. The electrical properties correlated to physical properties of eggs
i.e haugh unit, pH and viscosity. The albumen and yolk of native eggs, which
were placed in the cell system from acrylic and electrode plate conductor of
cuprum, were used as samples. Hi LCR Tester Hioki with dual probe (modified
from four probes) was used to measure electrical properties of samples. This
equipment was provided with fixed current source but varies in frequency. The
conductance of yolk and albumen increased exponentially if frequency signal was
boosted up. The electrical conductance range of albumen was higher than yolk on
all frequencies. The capacitance property decreased if frequency signal was
boosted up. The decrease was exponential especially at frequency under 100Hz.
The albumen capacitance was lower than yolk. The viscosity of yolk and albumen
during storage was decreasing. The value of pH was not affected. The pH of
albumen was between 9 and 10, and yolk was about 6. Multiple regression method
was used to get empiric equation of electrical conductance, capacitance, HU and
viscosity. The best correlation between electrical parameter and physical
properties is conductance equation of HU and viscosity at 1 kHz.
