| description | The current study evaluates the Pulsed Electric Field (PEF) technique for the extraction of polyphenols from the plants <i>Rosa canina</i>, <i>Calendula</i><i>officinalis</i> and <i>Castanea sativa</i>. These plants are traditionally used both for the preparation of therapeutic decoctions and the aromatization of beverages (alcoholic or not). Pulses of 10 μs duration were used to apply electric field intensities ranging from 1.2 to 2.0 kV cm<sup>−1</sup>. The period of the phenomenon was set to 1 ms, with a total extraction time of 20 min. The total polyphenol content as well as the identified polyphenolic compounds of the extracts were determined for monitoring and evaluation. To estimate the PEF effect, control extracts were prepared using the same process as PEF extracts but without the application of electric field. For all the three plant materials studied, the PEF technique appeared to be successful in increasing polyphenols extraction. The application of a moderate to high electric field, up to 1.4 kV cm<sup>−1</sup>, resulted in increased total and individual polyphenols recovery, reaching 63.79% and 84%, respectively, in the case of <i>Rosa canina</i> fruits. |
