Abstract The extra-virgin olive oil (EVOO) consumption provides several health benefits and it is increasing in many countries, including in Brazil. Considering that the importation of all the EVOO commercialized in the country is very expensive, the interest in cultivating olives in Brazil has arisen, in such a way of producing a Brazilian olive oil. Previous works performed at our laboratory analyzing these first Brazilian EVOOs showed that there is a significant variation in the phenolic compound contents among different crops, which could be originated from the olive cultivation or from the olive oil extraction procedures. The aim of this work is to evaluate the effect of ripening on the phenolic compounds content of the olives and of the EVOOs produced from them, evaluating different varieties cultivated in the Southeast region of Brazil. Six olive varieties will be studied, which will be cultivated in 4 distinct locations (Campos do Jordão/SP; Maria da Fé/MG; Consolação/MG; and Três Corações/MG) and collected in 3 different maturity stages, as well as the corresponding olive oils, all of this in two successive crops. Separation and identification of the phenolic compounds will be accomplished by reversed-phase high-performance liquid chromatography coupled to mass spectrometry. As a result of this study it is expected to obtain a better understanding about the effect of edaphoclimatic conditions on de olives ripening and how it affects the phenolic compound contents of the olives as well as of the olive oils extracted from these fruits, in order to obtain a high-quality Brazilian olive oil that also presents a significant content of phenolic compounds. | |
