The results have shown that the oil quality of Chemlali
olives deteriorated more rapidly during fruit storage in closed plastic bags than in perforated plastic boxes.
Therefore, the use of perforated plastic boxes is recommended for keeping the olives for longer
periods of storage.
The repeated measures analysis of variance of all parameters analyzed indicated that
the olive oil quality is mainly affected by the olives storage conditions (containers type and storage periods).
Finally, blends of extra-virgin olive oil and mildly deodorized low-quality olive oils can be detected by their alkyl esters concentrations.
