Description
Cold‑press oil extraction is a mechanical process that yields oil at low temperatures to preserve bioactive compounds.
Technical
Mechanical pressing disrupts oil‑bearing tissues, releasing oils rich in unsaturated fatty acids, tocopherols, and polyphenols. Minimal heat prevents oxidation of thermolabile compounds, maintaining antioxidant activity. The extracted oil is then separated by centrifugation or decantation.
