Pulsed Electric Field-Assisted "Green" Extraction of Betalains and Phenolic Compounds from <i>Opuntia stricta</i> var. <i>dillenii</i> Prickly Pears: Process Optimization and Biological Activity of Green Extracts.

ABSTRACT: Opuntia stricta var. dillenii (OPD) fruits are rich in betalains and phenolic compounds, which are recognized for their potential health-promoting properties. This study focuses on the optimization of pulsed electric field (PEF)-assisted solid-liquid green extraction (SLE) from OPD whole fruit, using response surface methodology (RSM) experimental design to obtain green extracts rich in bioactive compounds. The optimal PEF pre-treatment conditions (electric field strength and energy input) were determined based on the cell disintegration index (Zp), followed by optimizing SLE conditions (temperature, time, and ethanol content). High-performance liquid chromatography (HPLC-DAD-ESI-Qtof) was used to characterize the individual bioactive compound profile of the obtained OPD gree
