What Is Extra Virgin Olive Oil
Extra virgin olive oil represents the highest quality and least processed form of olive oil, extracted directly from olives through mechanical means without chemical processing. Its superior nutritional profile and rigorous production standards set it apart from other cooking oils.
Nutritional Profile
Extra virgin olive oil contains a dense concentration of beneficial nutrients. A single tablespoon (14 grams) provides:
| Nutrient | Amount |
|---|---|
| Calories | 119 |
| Total Fat | 14 grams |
| Saturated Fat | 2 grams |
| Monounsaturated Fat | 10 grams |
| Vitamin E | 13% Daily Value |
| Vitamin K | 7% Daily Value |
The oil’s primary components include powerful polyphenols, oleic acid and antioxidants like hydroxytyrosol. These compounds deliver significant anti-inflammatory and protective molecular benefits that support cellular health and metabolic function.
Production Process
Extra virgin olive oil production follows strict international standards that preserve its nutritional integrity. The extraction process involves:
- Harvesting ripe olives directly from trees
- Cleaning and sorting olive fruits
- Mechanical cold-pressing without heat or chemicals
