Equipment for determination of dielectric properties of vegetable tissue during its mechanical loading

Original language description

The internal structures of agricultural products are changed substantially during the products deformation. One of the main changes in this process is loss of the water content and water solutions generally due to squeezing out of the cellular sap. The water content can be detected also by electric conductivity measured at different frequencies. The precise measurement of the electric conductivity during deformation of soft agricultural products can be used as a simple indicative method for study of theprocesses that control squeezing out of the cellular saps including the filtration abilities of the cellular walls. The paper contains description of the experimental equipment that is able to detect impedance of the vegetable tissue specimens during their compression between two plates. The equipment saves to determine the sample impedance from direct measurement of three voltages in the circuit that contains the tested specimen. The equipment is able to analyse the specimen properties
