Methods of measuring electrical properties of biological tissue and their use for fully automated classification of beef carcasses

Original language description

The bioelectrical impedance analysis (BIA) was applied on 441 carcasses using an automatic measuring system with flat elastic electrodes with the surface area of 30 sq.cm located on the outside of the left half-carcass. The resistance and reactance at two frequencies, i.e. 1 kHz and 100 kHz were registered. A number of impedance values reveal significant correlations to the conformation of the carcass. Among all evaluated categories, the strongest correlation (r = 0.86) was found between conformation and the value D2/Xcp100k (relationship between the square of the distance between electrodes and the calculated parallel reactance at 100kHz). Significant relations were also identified for the fatness, particularly in the females. The calculated formulaefor the prediction of conformation show a considerable high positive index of determination of R2 = 0.85 for all categories.
