Olive oil pouring from bottle

Olive oil, extracted from olives, is one of the most versatile ingredients in Mediterranean and global cuisine, known for its health benefits.

About this subject

Olive oil is produced by pressing olives, the fruit of the olive tree (Olea europaea). Extraction can be mechanical or chemical, with extra virgin olive oil obtained from the first cold press without solvents or excessive heat, preserving phenolic compounds and aroma. This grade has the highest quality and acidity below 0.8%. Virgin olive oil has acidity between 0.8% and 2%, while refined olive oil undergoes processes that remove impurities but also reduce flavor and nutrients.

The main producers are Spain, Italy, and Greece, accounting for roughly 70% of global output. In Brazil, olive oil consumption has grown significantly in recent decades, driven by Italian and Portuguese immigration and the adoption of the Mediterranean diet. The country also has its own production, especially in Rio Grande do Sul, with varieties such as Arbequina and Koroneiki adapted to the subtropical climate.

Beyond culinary uses in salads, pasta, and meats, olive oil is valued for cardiovascular benefits due to its high monounsaturated fat content and antioxidants like oleuropein. Studies link moderate consumption of extra virgin olive oil to reduced risk of heart disease and inflammation. Proper storage in a dark, cool place away from heat and light is essential to preserve its properties. The smoke point of extra virgin olive oil is between 190°C and 210°C, making it suitable for light sautéing but not prolonged deep frying.
