Aging effect on apples bio-impedance using AD5933

Abstract

In this paper, the effect of the fruits aging on bio-impedance is experimentally studied. Bio-impedance analysis, as accurate and fast method is used to investigate and monitor group of apples properties during aging. This method provides an alternative method for investigating apples physical properties that are highly related to chemical properties. AD5933 impedance analyzer chip within the frequency range (5 KHz-100 KHz) and NI-ELVIS board within the frequency range (300 Hz-5 KHz) are used to investigate the changes in apple's properties during aging. According to experimental results, the observed changes in apples properties during aging can be highly related to bio-impedance changes. Different parameters as weight, Cole-Cole plot, impedance, and phase are discussed to investigate the aging effect.
