This work aimed to extract hemp seed oil using modified supercritical CO2 with ethanol, while optimizing the overall process through response surface methodology. The effects of extraction temperature (30-60 °C), pressure (10-20 MPa), and time (120-300 min) on yield, total phenols (TPC), tocopherols, oxidative stability index (OSI), chlorophylls, carotenoids, quality indices, color were assessed. For a maximum yield 28.83 g/100 g fresh seeds, was extracted at 50 °C 20 MPa for 244 min. In...
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...
