Olive oil has earned its place as a staple in healthy diets, especially in Mediterranean cooking. But not every type of olive oil offers the same benefits. Extra virgin olive oil (EVOO) is often held up as the healthiest and most flavourful option, while pomace olive oil is typically found at the lower end of the quality scale. Though it’s cheaper and sometimes used in bulk by restaurants, pomace oil isn’t the best choice if you’re looking for real nutritional value.
What Is Pomace Olive Oil?
Pomace olive oil is the lowest grade of olive oil available for consumption. It is not obtained through the traditional cold pressing of the olives. Instead, pomace oil is extracted from the leftover olive pulp, skins, pits, and water after the initial pressing. Since very little oil remains in this byproduct, chemical solvents, typically hexane, are used to draw out the remaining oil. The result is a heavily refined product that lacks many of the natural nutrients found in higher-quality olive oils.
Nutritional Quality: Stripped of Health Benefits
One of the biggest drawbacks of pomace olive oil is its lack of beneficial compounds. , by contrast, is rich in monounsaturated fats, polyphenols, vitamin E, and antioxidants, all of which contribute to its anti-inflammatory and heart-healthy effects. However, the refining and chemical extraction methods used to produce pomace oil strip away most of these valuable nutrients.
As a result, pomace olive oil offers minimal antioxidant activity and lower nutritional value, making it a poor substitute for more natural, less processed options. If you’re looking for olive oil for cooking that also supports your health, pomace olive oil is not the best choice.
Potential Contaminants and Chemical Residues
Another concern with pomace olive oil is the potential for chemical residues. The hexane used in the extraction process is a petroleum byproduct, and while final products are typically refined to remove these chemicals, trace amounts may remain. Additionally, high heat and chemical processing can generate trans fats and other oxidised compounds that are considered harmful when consumed over time.
In some countries, pomace oil has faced scrutiny due to the risk of polycyclic aromatic hydrocarbons (PAHs), which are carcinogenic compounds that can form during the high-heat extraction process.
Culinary Use: Less Flavour, Lower Smoke Point
From a culinary standpoint, pomace olive oil is less flavourful than extra-virgin olive oil. The refining process strips away the characteristic taste and aroma of olives, leaving behind a neutral, bland oil. While it has a relatively high smoke point, which makes it suitable for high-heat frying, it lacks the richness and depth of flavour that quality olive oils typically offer.
The Bottom Line
While pomace olive oil may seem appealing due to its lower price, it compromises on quality, nutrition, and potential safety. For those seeking the full health and culinary benefits associated with olive oil, extra virgin olive oil is a far better choice. Spending a bit more on a product that preserves the natural integrity of the olive is a worthwhile investment in both flavour and well-being.
