Difference between olive and extra virgin oil: what is the difference between an extra virgin olive oil and a simple olive oil? Here are all the details.

Olive oil is an edible oil obtained by mechanical extraction from the fruit of the olive tree (Olea europaea). We often hear aboutvirgin oilextra virginor simply olive oil. Let's analyze the differences starting with the comparison between olive oil and extra virgin olive oil.

Difference between olive and extra virgin oil

To sanction thedifference between olive oilisextra virgin olive oilis the EC regulation 2568/91. The denomination "virgin olive oil" or "extra virgin olive oil" are commercial terms regulated by the European Union in Directive 136/66 / EEC.

By law, theextra virgin olive oilit is obtained by mechanical extraction and has an acidity of less than 0.8%. Olive oil or "virgin olive oil" is always obtained by mechanical extraction but has a higher acidity which by law cannot exceed 2%.

Why is the acidity of an olive oil important? Because it is a quality indicator. Acidity represents the concentration of free fatty acids and. a fundamental parameter to evaluate the quality of an oil.

  • Acidity of extra virgin olive oil: maximum limit of 0.8 grams per 100 grams of product.
  • Acidity of olive oil 2 grams per 100 grams of product.

It is advisable to read the label because among the products on the market there is a further distinction: that linked to oil blends. If this technical difference doesn't tell you much, there are some notions you absolutely need to know.

The acidity of olive oil and the difference between extra virgin oil, virgin oil and olive oil

The acidity of olive oil is a classification based on the percentage of oleic acid present. The more acidic the oil is, the lower its quality will be.

An extra virgin olive oil will have a low acidity as the mill will only have used it for its productionoliveshealthy, who have not suffered. If the olives are attacked by insects or damaged by atmospheric agents, they will return an oil with a higher acidity.

In addition, there are also "olive oils"Not virgins. That is, olive oil obtained by mixing an oil obtained from the pressing of the olives and a rectified oil, that is, which has undergone a "rectification" process (chemical or physical) aimed at eliminating chemical and organoleptic defects.

When it comes to "olive oil" and not "extra virgin olive oil", the legislature does not establish a minimum percentage of virgin oil to add to the oily mixture. This means that you don't know exactly how much virgin oil is in the bottle you buy.

Olive oil can be a mixture with unknown components, you have no way of knowing how much virgin oil there is nor how much rectified oil is present. You just know that it has an acidity of no more than 2%. Sometimes, in'olive oil a minimum amount of virgin oil is added, just enough to make the smell and color acceptable.

For this reason, we always recommend buying extra virgin olive oil, even better if you go to a small producer, thus bypassing the large food distribution chain.
