abstract = {Orange peel by-product is a known source of bioactive compounds with several health benefits. This study focuses
on optimizing the conditions for pulsed electric field (PEF) technology as a pretreatment to obtain extracts
rich in phenolic compounds from the orange peel. A Box-Behnken design of 15 experiments with 3 independent
factors (field energy, number of pulses and pulse width) was performed. The phenolic content was extracted by
ultrasound technology and analyzed by HPLC-ESI-TOF-MS. Optimum conditions were 1.4 kV/cm and 30 pulses
of 110 μs achieving a recovery of 40.8 mg/g dry weight of phenolic compounds, 27.5% higher than obtained
without PEF. Besides, hesperidin and narirutin content increased by 29.4 and 38.9%, respectively. For the
antioxidant assays also significative increments (≥ 53%) were achieved. The combination of optimized PEF pretreatment
with ultrasound extraction has let to obtain orange peel enriched extracts in polyphenols with higher
antioxidant activity.},
