Rapid heating by microwave (MW) and radio frequency (RF) energy offers the possibility to reduce thermal treatment times in post-harvest pest control of mangoes. In order to understand interaction between the fruit and electromagnetic energy, dielectric properties (DPs) of mangoes were measured using an open-ended coaxial-line probe with an impedance analyzer. The influence of frequency (1–1800 MHz), temperature (20–60 °C) and ripening (16 days storage at 21 °C) on dielectric constant
