Simultaneous extraction of oil- and water-soluble phase from sunflower seeds with subcritical water

Highest amount of oil was obtained at 130 °C at a material/solvent ratio of 1/20 g/mL after 30 min of extraction. For all obtained oils minimal degree of hydrothermal degradation could be identified. High antioxidant capacities of oil samples could be observed. Water soluble extracts were degraded at temperatures ⩾100 °C, producing various products of hydrothermal degradation.
