Resumo: | The objective of this work was to characterize the chemical composition of olive (Olea europaea) oils produced in Southern of Brazil and correlate it with oxidative stability. Olive oils from the Arbequina, Coratina, Frantoio and Koroneiki cultivars were evaluated. A completely randomized experimental design was used, in a uniform arrangement, with three replicates. Acidity value, peroxide index, specific absorption, tocopherol content, phenolic compound content, carotenoid content, chlorophyll content, fatty acid profile, and oxidative stability were determined. The oils from the Coratina and Frantoio cultivars were classified as extra virgin-oils. The olive oil from the Coratina cultivar showed the highest levels of pigments, followed by the oil from Koroneiki. The oil from the Coratina cultivar also presents higher contents of phenolic compounds (1,725.5 mg kg-1) and tocopherols (437.8 mg kg-1). The major fatty acid in all samples is oleic acid. |

Foram avaliados azeites das cultivares Arbequina, Coratina, Frantoio e Koroneiki. Utilizou-se o delineamento experimental inteiramente casualizado, em arranjo unifatorial, com três repetições. Foram determinados índice de acidez, índice de peróxidos, absorção específica, teor de tocoferois, teor de compostos fenólicos, teor de carotenoides, teor de clorofilas, perfil de ácidos graxos e estabilidade oxidativa. Os azeites provenientes das cultivares Coratina e Frantoio foram classificados como extra virgens. O azeite da cultivar Coratina apresentou maiores teores de pigmentos, seguido pelo da cultivar Koroneiki. A cultivar Coratina ainda apresenta maiores conteúdos de compostos fenólicos (1.725,5 mg kg-1) e de tocoferois (437,8 mg kg-1). O ácido graxo majoritário em todas as amostras é o oleico.
