10-12 October 2007 A study has been carried out to evaluate the influence of integrated olive production on the
quality of Galega virgin olive oil. On three consecutive years, olive samples from two different groves
in integrated production were taken, and submitted to extraction in industrial mills. The analytical
determinations in olive oil were acidity, peroxide index, K232 and K270, sensory analysis, fatty acid
composition, total phenol compounds, tocopherols, oxidation stability and organophosphate pesticides.
Quality criteria were within the European Union limits for extra virgin olive oil, and the
organophosphate pesticides residues were always undetectable.
