- Mechanical Quiver: Tree are vibrated to drop fruit into internet, which is effective for large-scale operations.
- Whipping: A traditional method using poles to knock fruit down, though less common today due to likely tree damage.
Milling and Extraction
Once harvested, the olives must be process as quickly as possible - ideally within 24 hours - to prevent oxidation and fermentation. The operation of olive oil extraction has develop from heavy rock factory to sophisticated stainless blade systems that prioritise hygienics and temperature control.
The Key Steps in the Oil Mill
- Cleansing and Lavation: Olive are divest of leaf, twigs, and junk before being exhaustively wash in cold water.
- Crushing: The entire fruit, include the pit, is crushed into a thick, consistent paste.
- Malaxation: This is a all-important slow-mixing stage. The paste is stirred for 30 to 45 minutes to let oil droplets to cluster together, making extraction easier.
- Centrifugation: The paste undergoes high-speed spinning. Since oil is light than water and solid matter, the separator severalise these ingredient effectively.
⚠️ Tone: Conserve a low temperature, known as cold press, is life-sustaining during this point. Temperatures above 27°C (80.6°F) can cheapen the delicate flavors and reduce the nutritional value of the last product.
Comparison of Olive Oil Grades
| Course | Treat Method | Acidity Level |
|---|---|---|
| Extra Virgin | Mechanical/Cold Press | Below 0.8 % |
| Virgo | Mechanical/Cold Press | Below 2.0 % |
| Refined/Pomace | Chemical/Heat | Varies |
Filtration and Storage
After origin, the oil may comprise micro-particles of yield pulp. Many producer select to filter the oil straightaway to remove these sediment, which can otherwise make the oil to fluff prematurely.
