Olive oil quality is shaped during extraction. Key quality attributes are sensitive to:
Traditional extraction relies heavily on malaxation to release oil droplets. While effective, long malaxation times increase oxidation risk and can reduce the concentration of delicate compounds.
PEF addresses these challenges by enabling faster, gentler oil release.
Polyphenols are natural antioxidant compounds responsible for many of olive oil’s:
Higher polyphenol content is often associated with:
However, polyphenols are highly sensitive to oxidation and heat during processing.
Polyphenols are one of the defining elements of high-quality extra virgin olive oil. Their concentration depends not only on the olives themselves but also on how carefully the oil is extracted.
PEF improves polyphenol retention in several ways:
By opening olive cell membranes before malaxation, PEF allows oil to be released more quickly. This reduces the time the paste is exposed to oxygen.
PEF is a non-thermal process. It does not require elevated temperatures to improve extraction, helping preserve heat-sensitive polyphenols.
PEF helps release polyphenols stored inside olive cells that may otherwise remain trapped in pomace.
The result is often a higher polyphenol concentration in the final oil compared to conventional extraction.
Numerous studies and commercial installations have demonstrated that PEF can:
These results are not limited to laboratory trials; they are achieved in real production environments.
Furthermore, there are several real-world examples from customers who implemented the OPTICEPT® LO PEF-treatment in their operations.
Such as Atlas Olive Oils, which reported 5% more polyphenols. Or Moulin D’Olivette, who improved quality and reduced malaxation times by 50%.
Olive oil aroma is defined by volatile compounds that create notes such as:
These compounds are extremely fragile. Long malaxation times, oxygen exposure, and heat can cause them to evaporate or oxidize.
PEF enables:
This helps retain the natural aromatic profile of the olives, resulting in fresher and more expressive oils.
Flavor is a balance between:
PEF helps improve this balance by preserving the compounds that create these sensations, without introducing off-flavors.
Producers often report oils with:
Importantly, PEF does not create artificial flavors—it simply allows the natural characteristics of the olives to shine through.
Oxidation is one of the main causes of quality loss in olive oil.
By reducing:
PEF helps slow down oxidative reactions. This can result in oils with:
PEF does not replace traditional extraction equipment or methods. Crushers, malaxers, and centrifuges remain essential.
Instead, PEF enhances these steps by improving cell permeability before malaxation. This allows producers to achieve higher quality without altering their production philosophy.
High-quality olive oil depends on careful handling at every stage of production. While growers can control cultivation and harvest, extraction is where quality is either preserved or lost.
PEF technology improves olive oil quality by:
For producers focused on premium quality, consistency, and long-term value, PEF offers a powerful tool to protect and enhance what nature provides.
