Top Health Benefits, Uses, and Insights of Pomace Olive Oil
High smoke point and mild taste offer a versatile cooking choice for nutrient uptake.
Pomace Olive Oil: An Introduction
Pomace olive oil is a lesser-known variant extracted from the residual paste left after the mechanical pressing of olives. Unlike extra virgin olive oil, which is extracted directly from pressed olives, pomace olive oil involves further processing of olive skins, pits, stems, and pulp. Despite undergoing refining processes, it still retains valuable nutrients and offers a neutral flavor and high smoke point, making it suitable for various culinary purposes.

Nutritional Profile of Pomace Olive Oil
Pomace olive oil’s principal nutrient is oleic acid, a monounsaturated omega-9 fatty acid, which makes up around 75–85% of its total fat content. Research links oleic acid with improved heart health, reduced risk of metabolic disorders, and anti-inflammatory properties.
Source:
- Monounsaturated fats: Crucial for lowering LDL (“bad”) cholesterol.
- Minor bioactive components: Includes triterpenic acids, dialcohols, squalene, tocopherols, sterols, and phenolic compounds—these may aid heart health and antioxidant defenses.
- Polyphenols: While less than in extra virgin olive oil, pomace olive oil still retains some polyphenols, which are linked to reduced inflammation and potential protection from cardiovascular and neurodegenerative diseases.

How Pomace Olive Oil is Made
Extra virgin olive oil is produced by cold pressing olive flesh, but pomace olive oil is derived from “alperujo,” the solid by-product from pressing olives. This by-product includes skins, pulp, pits, and stones. The oil is then extracted using solvents and subjected to refining, which removes most impurities and some natural antioxidants. To enhance flavor and quality, it is often blended with small amounts of virgin or extra virgin olive oil.
Source:
- Step 1: Mechanical olive pressing leaves a residual paste.
- Step 2: Solvent extraction removes remaining oil from the paste.
- Step 3: Refining removes unwanted substances, making the oil more neutral in flavor and lighter in appearance.
- Step 4: Sometimes mixed with a bit of virgin olive oil for taste and nutritional boost.
Pomace Olive Oil vs. Extra Virgin Olive Oil
| Aspect | Pomace Olive Oil | Extra Virgin Olive Oil |
|---|---|---|
| Source | Olive pulp, skins, pits (post-pressing) | Freshly pressed olive flesh |
| Processing | Solvent extraction & refining | Cold-pressed, minimal refining |
| Antioxidants & Polyphenols | Low (some lost in refining) | High (preserved) |
| Flavor | Mild, neutral | Strong, fruity |
| Smoke Point | High (240°C) | Lower (about 190°C) |
| Price | Affordable | Premium |
| Uses | Baking, frying, sauteing | Salads, dressings, dips |
Key Health Benefits of Pomace Olive Oil
Though not as nutrient-dense as extra virgin olive oil, pomace olive oil offers unique health benefits, supported by research. Below are its top potential advantages:
1. Supports Heart Health
- Contains oleic acid, which can lower LDL cholesterol and support cardiovascular wellness.

2. May Reduce Visceral Fat and Improve Metabolic Markers
- Clinical trial data suggest regular intake of pomace olive oil (up to 45g per day) can reduce visceral fat, which is linked to diabetes and heart disease risk.
Source: - Increased leptin levels seen in people with high cholesterol, possibly helping control appetite and weight.
3. Blood Sugar Control and Lower Risk of Diabetes
- Pomace olive oil may improve insulin resistance and sensitivity, indicating a benefit for blood glucose control.
Source: - Potentially reduces parameters related to waist circumference and lipid oxidation.
4. Anti-Inflammatory Effects
- Monounsaturated fats help control inflammation, which underlies many chronic diseases.
- Polyphenols and other minor compounds can reduce inflammatory markers, although amounts are lower than in extra virgin olive oil.

5. Nutrient Absorption and Cell Health
- Supports absorption of fat-soluble vitamins (A, D, E, K).
- Plays a role in cell membrane formation, blood clotting, and muscle function.

6. Safety and Regulations
- Strict international standards limit the presence of harmful substances (PAHs, benzopyrenes) in pomace olive oil, particularly in the EU (2 parts per billion). Proper refining can remove unwanted chemicals.

Culinary Uses and Practical Advantages
Pomace olive oil’s high smoke point and mild flavor make it a favorite for commercial kitchens and home cooks alike. It’s especially suited for techniques where premium olive flavor isn’t necessary.
- Baking – keeps cakes and pastries moist without imparting a strong flavor.
- Frying – stable at high temperatures, does not break down easily.
- Sauteing & Stir-frying – neutral taste allows other flavors to shine.
- Mayonnaise, Marinades – blends well, does not overpower dishes.
- Affordable option for large-scale food preparation.
Environmental and Economic Impact
- Uses by-products: Pomace olive oil production utilizes what would otherwise be agricultural waste, contributing to sustainability.
- Lower cost: Making use of all parts of the olive helps reduce overall costs and makes olive oil products more accessible.
Potential Downsides and Concerns
- Lower antioxidant content: Like most refined oils, pomace olive oil is lower in polyphenols and natural antioxidants than cold-pressed oils.
- Possible blend with other oils: Some commercial pomace olive oils may be blended with seed oils. Always check the label for purity.
- Less flavor: If taste is a priority for your dish, extra virgin olive oil is generally preferred.
- Not suitable for raw applications: For dressings and dips, use extra virgin olive oil to maximize nutritional and flavor benefits.

How Does Pomace Olive Oil Compare to Other Oils?
| Oil Type | Smoke Point | Monounsaturated Fat | Polyphenol Content | Cost |
|---|---|---|---|---|
| Pomace Olive Oil | 240°C | High | Moderate | Low |
| Extra Virgin Olive Oil | 190°C | High | High | High |
| Sunflower Oil | 225°C | Low | Very Low | Medium |
| Algae Oil | 280°C | Very High | Variable | High |
Algae oil is an emerging alternative with more omega-9 fats and less saturated fat than both olive and pomace olive oils, and its smoke point makes it even better for high-heat cooking.
