The measurement of the impedance of the ice-cream mix is done by applying to the test tube a sinusoidal voltage signal. The measurement of the impedance of the analyzed sample is obtained by applying Ohm's law. The system applies a voltage signal at known frequency to one of the electrodes in direct contact with the ice-cream mix sample to be measured. On the other electrode the current is then measured. In this study it has been verified that the measurement of the impedance angle phase shift Φ is a reliable tool to determine the microbial charge of an ice cream mix.
