On the contrary, HIPEF treatments in monopolar mode were found to
be more effective in keeping the broccoli juice vitamin C than those applied
in bipolar mode, except for treatments carried out at 15 kV/cm,
where bipolar mode led to higher or similar RC of vitamin C than
monopolar mode pulses (Fig. 2). For instance, at 35 kV/cm for 1250 μs
vitamin C RC of broccoli juice was almost 10% higher in monopolar
mode treatments than that observed in bipolar mode.
