Olive branches with green olives

Olive branches with green olives: a symbol of peace and essential ingredient of the Mediterranean diet, cultivated for millennia.

About this subject

The olive tree (Olea europaea) is one of the oldest cultivated fruit trees, with records dating back over 6,000 years in the Mediterranean region. Green olives are harvested before full ripeness, when they still have a green color and firm texture. Unlike black olives, which ripen completely on the tree, green ones undergo a curing process to remove oleuropein, a natural bitter compound. This process may involve immersion in brine, water, or lye, followed by fermentation. The result is a versatile fruit, eaten as an appetizer, in salads, pizzas, and pastes. Global table olive production exceeds 2.5 million tons annually, led by Spain, Italy, Greece, and Turkey. Beyond culinary use, the olive branch carries strong symbolism: in Greek mythology, Athena gifted the first olive tree to the city of Athens, and since then it represents peace, wisdom, and prosperity. The flag of the United Nations features two olive branches, reinforcing this universal meaning. In Brazil, olive cultivation is expanding in the South and Southeast regions, especially in Minas Gerais and Rio Grande do Sul, adapting to subtropical climates.
