Abstract: | The effect of location of fruit in canopies of hedgerow olive trees (Olea europaea L., cv. ‘Arbequina’) on quality of virgin oil was tested by analyzing oils extracted from different height layers and faces
of nine olive hedgerows (6 North–South oriented and 3 East–West). Although sensory attributes were not different, other oil
quality parameters may be significantly modified by fruit position. Oils extracted from fruits harvested from higher layers
exhibited significantly higher stability against oxidation, along with higher palmitic acid, linoleic acid and phenol contents,
but lower oleic acid content. Oils extracted from fruits harvested from East and North facing hedgerows oriented North–South
and East–West, respectively, exhibited higher oleic contents and lower saturated and polyunsaturated fatty acid contents.
The mean phenol content of oils extracted from fruits from a North–South oriented hedgerow was significantly greater from
one of the East–West oriented hedgerows. These findings may be relevant for the design of future olive hedgerows destined
for olive oil production. |
