摘要

In the present research, hemp seed oil extraction was optimized using pulsed electric field (PEF) technology under varied conditions, i.e., PEF strength (0.25, 3.25, and 6.25 kV/cm) and pulse numbers (10, 30, and 50). Extraction of hemp seed oil was performed through solvent extraction following PEF processing, using different hexane-to-isopropanol ratios (0:100, 50:50, and 100:0 v/v %). The research focused on maximizing extraction efficiency, phenolic content, and antioxidant potential, while reducing peroxide value and pigmentation, via response surface methodology (RSM) in conjunction with Box-Behnken experimental design (BBD). The variance analysis indicated that PEF treatment significantly affected all variables (p < 0.05), except for phenolic content (p > 0.05), with an R2 value of more than 0.96, confirming the model's appropriateness. The optimal conditions were identified as a solvent ratio of approximately 3:2 (hexane: isopropanol), a PEF intensity of 2.02 kV/cm, and 10 pulses. Under these conditions, the oil yield reached 23.5%, total phenolic content was 3.02 mg GAE/g, antioxidant activity (DPPH inhibition) was 81.3%, peroxide value was maintained at 5.7 meq O₂/kg, and the color index was 61.4. These results demonstrate that precise optimization of PEF pretreatment can enhance both the yield and quality of hemp seed oil.
