This research explores green-technology alternatives to extract vegetable oils as alternatives to hexane, a non-renewable solvent, focussing on sunflower oil. It compares pressurized liquid extraction (PLE) with ethanol and supercritical fluid extraction (SFE) with CO. Both processes aim to maximize oil yield, tocopherol content (α, β, γ, and δ), fatty acid profile (FA), and triacylglycerol (TAG) composition.

The determination of the primary fatty acids responsible for product acidity can provide a higher quality product. Sunflower (scCO/PLE-ethanol) and soybean (PLE-ethanol/PLE-hexane) samples were evaluated.
