Inappropriate practices during the olive oil extraction process
and bad quality of the olive fruits promote the formation of hydrolytic
and oxidative deteriorations confirmedby the high quality indices
values, concentrations of FAAEs and sensory characteristics
defects. It is obvious that the fruits storage in open perforated plastic
boxes prevent the fast alteration that is produced in oils extracted
from fruits stored in closed plastic bags.
Indeed, the holes in the
boxes are very important to allow for ventilation of the olives, delaying
the fermentation processes in the stored fruit.
Moreover, the use of boxes for the storage of olives intended for oil would mean a significant
improvement in quality for the olive oil industry.
The determination of the total amount of methyl and ethyl
esters of fatty acids could be used as a parameter for the detection
of fraud of extra-virgin olive oil with 30% of mild deodorized lowquality
olive oil
