Composição físico-química de azeite extra virgem produzido no município de São Borja/RS

Abstract

The expansion of olive growing in Brazil is influenced by a growing demand for olive oil and favorable soil and climate conditions in some regions. The olive tree (Olea europaea L.), traditionally adapted to the Mediterranean climate, has been introduced in Brazilian subtropical areas, exploring new frontiers with high potential for quality olive oil production. This study was conducted in the municipality of São Borja, Rio Grande do Sul, aiming to analyze the quality of olives and the extra virgin olive oil extracted from the 'Koroneiki' cultivar. The physicochemical parameters of the harvested olives and the 'Koroneiki' olive oil were evaluated. The oil from this cultivar exhibited an acidity of 0.25%, a peroxide index of 11.76 mEqO₂/kg, and specific extinction values within the standards for extra virgin olive oil. These parameters classify the oil as high quality, in compliance with Brazilian regulations. This study highlights the importance of soil and climate zoning for adapting olive cultivation in Brazil, as well as the need for further research to optimize management and productivity in subtropical areas.
