Determination of electric and dielectric conductivity of fruits and vegetables

Abstract

The article describes the research results to determine fruits and vegetables’ electrical and dielectric conductivity. The electrical conductivity is characterized, and the experimental method of its determination and the equipment used are given. Also, the topic’s relevance, keywords, methods of calculation in the experimental process, the electrical conductivity of crushed, cut varieties of fruits (apricots, apples, plums) and carrots, and the results of a study to determine the dielectric constant. MevaThe results of the dielectric properties of tula and cut varieties of different sizes (apricots, apples, plums) and vegetables (carrots, potatoes, beets, and onions) are presented. The curves of the dependence of the specific electrical conductivity of crushed fruits, plums, apples, and carrots on the EMF voltage are obtained. The specific electrical conductivity at cm is a maximum of 0.191 cm / m. Also, during the operation of the electrodes in the cell -30 s, the electrical conductivity first increases rapidly; after 10 seconds, the growth decreases, and at a certain maximum time - 18 s decreases, and the maximum size here is in the range of 0.209 to 0.230 cm/cm. The temperature dependence of the specific electrical conductivity of fruits and vegetables greatly affects their temperature on electrical conductivity.
