The dependence of the active and reactive impedance components of a three-element electrical circuit of substitution of a biological object on the change of the parameters of the electrode impedance is investigated.
The freshness of the meat is one of the indexes of its quality. However, it is often frozen to be transported and stored. After unfreezing, it is offered to a consumer as a fresh one. Quality of that meat is worse, but the price is, mainly, identical to the cost of meat that wasn’t frozen.
Vegetables’ pollution by mercury, copper, zinc and arsenic concerning the EU standards is not permitted, whereas in Ukraine it has to be within the limits of permissible concentrations. The urgent task is to develop an express method for controlling the concentrations of heavy metals in vegetable production. We have investigated the electrical characteristics of vegetable juices aiming the operative control of heavy metals concentrations in them.
