Milk is a kind of food that is consumed a lot due to its high nutrient content,
however, the kinds and quality vary a lot and is easily spoilt. Electrical impedance
spectroscopy (EIS) is a way to characterize a material by measuring the real and
imaginary impedance of that material. One readily available and economical IC
for EIS is AD5933. Experiments are conducted using AD5933-based system, on the
frequency range of 30 – 150 Hz, using parallel plate electrodes to observe the
impedance spectrum of UHT and pasteurized milk left in open air for a period of
time. Experiment results show that the AD5933 can produce different impedance
spectra for different kinds of milk, that fits the Randles and constant phase element
circuit model. On the other hand, system accuracy needs to be improved to detect
the impedance changes with time of the milk. |
