The use of the extra virgin olive oil as covering in food preserves presents some problems and still today object of study. With this research it was investigate the changes of some analytical parameters that occur during the storage in the olive oils used as covering in eggplant preserves. It was ascertained that in the oils in presence of the eggplants a drastic decrease of the total phenols was verified immediately after the thermal treatment affecting the oxidative processes. Besides it was observed that in all the oils stored under light the values of the K-270. DeltaK, the total chlorophylls and the 1,2-DG36/1,3-DG36 ratio were significantly changed.

Abstract
The use of the extra virgin olive oil as covering in food preserves presents some problems and still today object of study. With this research it was investigate the changes of some analytical parameters that occur during the storage in the olive oils used as covering in eggplant preserves. It was ascertained that in the oils in presence of the eggplants a drastic decrease of the total phenols was verified immediately after the thermal treatment affecting the oxidative processes. Besides it was observed that in all the oils stored under light the values of the K-270. DeltaK, the total chlorophylls and the 1,2-DG36/1,3-DG36 ratio were significantly changed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
