Electric Field and Pressure Assisted Extraction of Mushkbudji Rice Bran Oil: Optimization, Structural and Antioxidant Characterization and Comparative Evaluation of Soxhlet Extraction

The present study investigates a novel electric field and pressure assisted extraction (EF PAE) technique for the recovery of rice bran oil (RBO) from the geographically indicated Mushkbudji rice (Oryza sativa L) compared to conventional Soxhlet extraction. Process variables like electric field strength (10–30 V/cm), positive pressure (0–10 kg/cm2), and temperature (10–20 ℃) were evaluated for their effect on the efficiency of extraction. The maximum oil recovery (16.01 g/100 g) was achieved at 30 V/cm, 10 kg/cm2, and 20 ℃, representing a 33.4
