Microwave‐Assisted Extraction of Hemp Seed Oil: Process Optimization for Enhancing Oil Yield and Bioactive Compound Extractability

International Journal of Food Science, Journal Year: 2025, Volume and Issue: 2025(1)

Published: Jan. 1, 2025

Hemp seed oil is a valuable source of unsaturated fatty acids. However, its high degree unsaturation makes it highly susceptible to oxidation, which can compromise quality and nutritional value. Enhancing stability be achieved by incorporating antioxidant compounds naturally present in the seeds. A deeper understanding interactions between extraction process oil's composition would provide insights for optimizing both bioactive properties. In this context, study was aimed at investigating microwave-assisted hemp oil, enriched with compounds, using response surface methodology. Three factors were investigated: microwave power (600, 750, 900 W), cosolvent percentage (0%, 5%, 10% ethanol relative hexane), time (5, 10, 15 min). Several responses studied, including yield, total phenolic content (TPC), tocopherols, oxidative index (OSI), chlorophylls, carotenoids, indices (peroxide value conjugates [diene triene]), color (L∗, a∗, b∗, C∗⁣ab, h ab). The optimum conditions 800 W, 7.5% EtOH, 13.60 min, reaching maximum yield 30.69%. resulting showed OSI (28.60 h) richness TPC, chlorophylls (88.55, 510.64, 27.21, 99.68 mg/kg respectively) along an acceptable oxidation intense parameters (L∗ = 33.54, a∗ -4.01, b∗ 3.17).
