How to differentiate the real from the fake one

Extra virgin olive oil (EVOO)


EVOO is a high-quality, unrefined olive oil that is renowned for its exceptional taste and numerous health benefits. Here's a detailed look at how it is processed, its unique qualities, health benefits, reasons to choose it over other types of olive oil, and how to verify its authenticity.


Processing of Extra Virgin Olive Oil:


  • Harvesting: The process begins with the harvesting of ripe olives. Hand-picking or using mechanical equipment is common.

  • Milling: The harvested olives are then washed to remove any debris and dirt. They are crushed into a paste using large stone mills or stainless steel equipment.

  • Malaxation: The olive paste is gently mixed, allowing the oil droplets to combine, promoting the separation of oil from the paste.

  • Centrifugation: The paste is then subjected to a centrifuge, which separates the oil from the water and solids. This process is essential for maintaining the oil's purity.

  • Decantation: After centrifugation, the oil is decanted to remove any remaining water and impurities.

  • Filtration: Some EVOO producers choose to filter the oil to further remove impurities. However, filtering is not mandatory for extra virgin olive oil.

  • Bottling: The final EVOO is bottled in dark, opaque containers to protect it from light and air, which can cause degradation.

  • Why Extra Virgin Olive Oil (EVOO):

  • Exceptional Flavor: EVOO has a rich, robust, and fruity flavor, making it a prized ingredient in culinary applications.

  • Health Benefits: EVOO is loaded with antioxidants, monounsaturated fats, and various bioactive compounds that contribute to its numerous health benefits.

10 Health Benefits of Extra Virgin Olive Oil:


  1. Heart Health: EVOO is associated with reduced risk of heart disease due to its ability to lower bad cholesterol and improve overall cardiovascular health.

  2. Anti-Inflammatory Properties: The oil contains oleocanthal, a natural anti-inflammatory compound.

  3. Cancer Prevention: Some studies suggest that EVOO may have cancer-fighting properties, particularly against breast and colorectal cancer.

  4. Antioxidant Properties: Rich in antioxidants, EVOO can protect cells from oxidative damage.

  5. Brain Health: It may support brain health and reduce the risk of cognitive decline.

  6. Weight Management: EVOO can help with weight management due to its satiating effect and ability to regulate appetite.

  7. Digestive Health: It may improve digestion and help prevent gastric ulcers.

  8. Skin Health: Applied topically or consumed, EVOO can contribute to healthy skin.

  9. Anti-Aging: The antioxidants in EVOO may slow down the aging process.

  10. Diabetes Management: It can improve insulin sensitivity and help manage blood sugar levels.

Why Not to Use Other Types:


Extra virgin olive oil is the highest quality among olive oils because it is unrefined, meaning it is produced through mechanical processes without chemical treatments. Other types, like "light" or "pure" olive oils, are often refined, meaning they have been chemically processed and lack the same health benefits and flavor profile.


Verifying Authenticity:



To ensure you're getting genuine extra virgin olive oil, consider these steps:

Check for Certification: Look for seals of authenticity, such as the "COOC" (California Olive Oil Council) in the United States or the "DOP" (Protected Designation of Origin) in Europe.



Read Labels: Check the label for key information, including the harvest date, region of origin, and acidity level.


Taste and Smell: Authentic EVOO has a distinct flavor and aroma, often described as grassy, fruity, or peppery.


Avoid Clear Bottles: EVOO is sensitive to light, so choose bottles that are dark or opaque.


Buy from Reputable Sources: Purchase from trusted producers or retailers, especially those with a strong reputation for quality.


Third-Party Testing: Some organizations conduct independent testing and certification for olive oils. Look for their seals on the bottle.


By following these steps, you can increase your chances of getting genuine extra virgin olive oil, reaping its exceptional taste and health benefits.
