“…This is due to specific frequencies, including 915 MHz & 2.45 GHz, being set aside for use in microwave ovens & industrial microwave heating [160]. When water molecules are exposed to microwave radiation, the molecular dipoles try to align in the direction of the applied electromagnetic field [161]. As the applied field oscillates, the dipoles attempt to follow the oscillations, and the electromagnetic energy it transferred into thermal energy as a result of molecular friction and dielectric loss.…”

“…As the applied field oscillates, the dipoles attempt to follow the oscillations, and the electromagnetic energy it transferred into thermal energy as a result of molecular friction and dielectric loss. The alternating electric field causes the charged ions to oscillate back and forth, resulting in heating due to the agitation caused by the ions bumping into other molecules [161]. The dielectric properties of a food material are dependent on its composition, especially that of water and minerals.…”

“…Кроме того, частоты 433,92; 896 и 2375 МГц используются в основном за пределами США [9]. При этом коммерческое применение этих частот для пастеризации и стерилизации на сегодняшний день имеет малое распространение, хотя они используются при выпечке и других процессах пищевой промышленности [10,11].…”

“…A aplicação de micro-ondas na secagem de produtos alimentícios, quando controlada, acelera a cinética de secagem, como o observado por (BOTHA; OLIVEIRA; AHRNÉ, 2012;FENG;YIN;TANG, 2012;FIGIEL, 2009;KONÉ et al, 2013) sendo que o produto processado pode atingir qualidade superior àquela obtida pelos métodos convencionais. Em contrapartida, o fenômeno do encolhimento durante o processo de secagem ainda não está totalmente esclarecido.…”
