- Olive ripening and harvest time in portuguese cultivars of “Beira Interior“ regionPublication . Ramos, António Santos; Peres, Maria de Fátima; Lopes, P. Simões; Alves, M.C. PinheiroPortuguese growers of “Beira Interior”, an inland region in the centre of Portugal, start harvesting olives only in late November or December and finish in January and sometimes February. Studies on olive ripening carried out in different groves showed that, in general, oil content (% d.w.) stabilises during November and ripening index rises regularly throughout the sampling period. However, there were some differences among cultivars. The results suggest that harvest can begin from mid- -October to the 1st fortnight of November, according to location, for ‘Galega’, in the 1st fortnight of December for ‘Bical’, in the 1st fortnight of November for ‘Carrasquinha‘ and in the 2nd fortnight of November for ‘Cornicabra’, therefore harvest time should begin long before the traditional time.
- Characterization of three monovariety olive oils of Beira Baixa (Portugal)Publication . Peres, Maria de Fátima; Henriques, Luís; Alves, M.C. Pinheiro; Lopes, P. SimõesBeira Baixa olive oil is mainly produced with Galega cv. Galega olive ouil is veryu stable and provides flavour and taste that are traditional for portuguese consumers. Bical and Cordovil de Castelo Branco cvs. are also important in the olive grove of the region. The goal of this study is to understand the role of the composition of the monovariety olive oils (mainly fatty acid composition and total phenol compounds) on the quality of Beira Baixa olive oil. Results for sterols are also shown.
- Oil content of three olive cultivars (Olea europaea L.) in Beira Baixa (Portugal)Publication . Alves, M.C. Pinheiro; Lopes, P. Simões; Henriques, Luís; Peres, Maria de FátimaThe three main cultivars of Olea europaea L. at Beira Baixa are Galega vulgar, Bical and Cordovil de Castelo Branco. Humidity and oil content, by NMR, for the monovariety olive pastes were studied for two years, 1998/99 and 1999/2000.The results showed that Galega vulgar had significantly lower oil content when compared with Bical and Cordovil de Castelo Branco; but Bical and Cordovil de Castelo Branco did not differ significantly from each other concerning this parameter.The humidity values observed for the three cultivars are significantly different: Cordovil presents similar values during the three harvests while Galega vulgar and Bical showed their maximum values at the second harvest.
