Classification PDO olive oils on the basis of their sterol composition by multi...

The sterol compositions (GLC/FID/capillary column) of monovarietal olive oils (51 samples) from the most important cultivars of northeastern Portugal (Cvs. Cobranc¸osa, Madural and Verdeal Transmontana) and 27 commercial samples of olive oils with protected denomination of origin (PDO) from the same region and cultivars were evaluated. Δ-sitosterol, Δ5-avenasterol and campesterol were the most representative st...

Effect of olive fruit fly infestation on the quality of olive oil from cultivar...

Olives (Olea europaea L.) from cultivars Cobrançosa, Madural and Verdeal Transmontana were collected separately and divided into two different groups according to the presence or absence of infestation by the olive fruit fly (Bactrocera oleae Gmel.). These two groups were then mixed in varying percentages to create five groups of olives per cultivar with infestation levels: 0, 12.5, 25, 50 and 100%. Each group ...

Discrimination of varietal olive oils of the portuguese cultivars Cobrançosa, M...

The aim of the present study was to check the possible use of the fatty acid profile to differentiate varietal olive oils of the three most important cultivars in Northeast Portugal (Cobrançosa, Madural and Verdeal). Fifteen varietal olive oils from each of the three cultivars were...
