    Being dependent on temperature and frequency, dielectric properties are related to various types of food. Predicting multiple physical characteristics of agri-food products has been the main objective of non-destructive assessment possibilities executed in many studies on horticultural products and food materials.

There has been much less concentration on studies of low-frequency properties of biological materials. However, the behavior of materials exposed to low-frequency electromagnetic fields, and a better understanding of these phenomena, may open up new applications and potentially useful measurements.
