Thermophysical properties were directly measured by the KD2 Pro multimeter (Decagon, USA), a fully portable thermal properties analyzer that uses the transient line heat source method to measure thermal conductivity, resistivity, diffusivity and specific heat,using the SH-1 (Dual Needle Sensor) inserted in the preconditioned slices. The thermal conductivity was provided directly by the properties analyzer, while specific heat was obtained by multiplying the volumetric specific heat given by the device, by the unripe banana apparent density.
