The highest relative content (RC) of both lutein (121%) and β-
carotene (130%) were reached at 35 kV/cm and 2000 μs in bipolar
mode (Fig. 1). In agreement with the present research, Torregrosa,
Cortés, Esteve, and Frígola (2005) observed a RC up to 187% of lutein
and 117% of β-carotene in orange–carrot juice treated by HIPEF at
35 kV/cm for 200 μs
