Freshness evaluation of Ezoshika meat based on bioelectrical impedance analysis (BIA) using LCR meter is carried out to estimate the quality of the meat. An arc is extracted from a locus of measured impedance to evaluate the condition of the meat. It is revealed that freshness of the meat may be estimated from the position of center of the arc. The arcs obtained by two types of equivalent-circuit models and a simple least squares method (LSQ) are compared. It is also found that the arc extracted by the LSQ explains the measured result well.
