Olive oil pouring from bottle

Olive oil, extracted from olives, is a cornerstone of the Mediterranean diet and a global symbol of culinary excellence.

About this subject

Olive oil is a vegetable oil obtained by pressing olives, the fruit of the olive tree (Olea europaea). Its production dates back thousands of years, with evidence of cultivation in the Eastern Mediterranean as early as 6000 BC. Today, Spain is the largest producer, followed by Italy and Greece. Brazil imports large quantities, mainly from Portugal and Spain, but also has emerging production in regions like Serra da Mantiqueira and the South.

Classification depends on extraction method and acidity. Extra virgin olive oil is the highest quality, with maximum acidity of 0.8%, obtained through mechanical processes without solvents. Virgin olive oil has acidity up to 2%, while refined olive oil undergoes chemical treatments. In Brazil, regulations require that products labeled as "azeite" be pure olive oil, with blending prohibited.

Culturally, olive oil is a staple in Mediterranean cuisine, used in salads, pasta, fish, and bread. Rich in monounsaturated fats and antioxidants like polyphenols, it is linked to reduced cardiovascular risk. Interestingly, color can range from green to golden, depending on harvest time and olive variety. The long exposure technique captures the oil's flow, highlighting its viscosity and characteristic sheen.
