Description
Oil‑seed expeller roasting and extraction combines controlled thermal roasting with high‑pressure pressing to inactivate enzymes and increase oil yield.
Technical
The process uses heat (120–180 °C) to denature lipases, reducing free fatty acids, while mechanical pressure (4–6 kN) breaks down cell walls and removes moisture. The resulting oil has lower oxidation potential and a distinct roasted flavor profile.
