Resumo: | The major challenge today for the application of PEF in the industry has interest to increase the production capacity and improve the quality of food products. PEF pre-treatment is a multifactorial process. In addition to the electric field intensity, pulses number and the capacitor value, the configuration of the treatment chamber now presents a significant parameter in this process.Cylindrical and square parallelipedic treatment chambers (TC) are compared and their effect is studied with variation of electric field, number of pulses and capacitor value at frequency of 1Hz. The results show that the cylindrical treatment chamber showed higher beet juice yield with all studied parameters. The quality of extracted juice estimated in terms of absorbance at 530 nm wavelength were determined for each sample and results show that using a cylindrical treatment chamber configuration in PFE technology  gives a  good juice quality compared with square parallelipedic treatment chamber. The energy consumption during PEF treatment is reduced in the cylindrical treatment chamber due to the low values of the electric field, pulses number and capacitor value compared with square parallelipedic treatment chamber.
