Pulsed electric field treatment of citrus fruits: Improvement of juice and polyphenols extraction

Citrus fruits are valuable sources of bioactive compounds (vitamins, antioxidants, carotenoids and flavonoids) and their processing represents an industrial importance. An application of PEF to whole fruits may be useful for improving the efficiency of juice extraction from different citrus fruits. The concentration of polyphenols in the extracted juice could be significantly enhanced by the treatment of citrus peels with PEF at high electric field strength.
