The antioxidant activity of two virgin olive oils, obtained from the same olive (Olea europaea sativa) batch but processed with different hammer crushing conditions, was evaluated by measuring their protective action towards linoleic acid peroxidation in a micellar system. The antioxidant efยฎciency

## Abstract In this work, the simultaneous separation of ten phenolic compounds (protocatechuic, __p__โcoumaric, __o__โcoumaric, vanillic, ferulic, caffeic, syringic acids, hydroxytyrosol, tyrosol and oleuropein) in extra virgin olive oils (EVOOs) by isocratic RP CEC is proposed. A CEC method was o
## Abstract A fast and automated method is proposed for determining the oxidative stability of virgin olive oil by using ultrasound. The ultrasound microprobe (3โmm in diameter) was directly immersed into the olive oil sample contained in a test tube. The most influential variables in the oxidation
