Dielectric Characterization of Fruit Nectars at Low RF Frequencies

Abstract: Dielectric properties of apple, apricot, peach, and pear nectars were studied in the frequency range from 15 kHz to 30 MHz and the temperature range from 25 to 60°C. Both the relative dielectric constants and the dielectric loss factors decreased by increasing frequency and increased linearly with increasing temperature with values in the order 10 4 -10 2 and 10 5 -10 2 , respectively. The power dissipation densities and the power penetration depths were found to increase linearly with temperature. Power dissi… Show more

“….27 mm at 2450 MHz. The decreased d p as frequency increased was also reported on other foods and agricultural products, e.g., fruits (Lombardo et al, 2015), peanut kernels (Zhang et al, 2016) and milk (Muñoz et al, 2018). Since d p was influenced by the frequency and solids-not-fat content greatly, choosing an appropriate thickness is very important to offer accurate measurement results when detecting solidsnot-fat content in skim milk.…”

“…When the solids‐not‐fat content increased from 10.04% to 14.68%, d p decreased from 81.53 to 66.61 mm at 27.12 MHz, from 70.22 to 56.44 mm at 40.68 MHz, from 30.86 to 23.28 mm at 915 MHz and from 11.89 to 10.27 mm at 2450 MHz. The decreased d p as frequency increased was also reported on other foods and agricultural products, e.g., fruits (Lombardo et al ., ), peanut kernels (Zhang et al ., ) and milk (Muñoz et al ., ). Since d p was influenced by the frequency and solids‐not‐fat content greatly, choosing an appropriate thickness is very important to offer accurate measurement results when detecting solids‐not‐fat content in skim milk.…”
