“…In total, 5 g of the dry orange peel powder and 75 ml of deionized water were mixed, and then, they were transferred to the PEF chamber. The orange peel was treated with different parameters, including electric field intensity (2.0, 4.0, 6.0, 8.0, and 10.0 kV/cm), pulse number (10, 20, 30, 40, and 50), liquid-solid ratio (5:1, 10:1, 15:1, 20:1, 25:1, and 30:1), and the temperature (25,35,45,55,65, and 75 • C); meanwhile, the sample without PEF, i.e., 0.0 kV/cm and 0 pulses was used as the control. After the treatment, the mixture was filtered to obtain the SDF extract; then, it was separated by ethanol precipitation to detect the content of SDF.…”
