Estudios de migración en aceites de oliva virgen extra envasados en PET

Resum

This research, related to the food safety, is focused on the migration from the food packaging materials to the food, which is actually an issue of concern. The study was developed with extra olive oil of different varieties (Picual, Arbequina and Hojiblanca) packaged in PET. The studies have been developed considering extreme conditions of temperature, time and exposure to light, simulating ways of conservation, storage or transport that could be carried out in warm climate countries. Within the substances susceptible to migrate, the research has focused on antimony (Sb), used as a catalyst in the manufacture of PET. Also, arsenic (As), cadmium (Cd) and lead (Pb), elements of legislative interest, have been analyzed. At the same time, the influence of the treatments on the degradation of the physical-chemical and organoleptic qualities of these oils, as well as the plastic material (PET) of the containers, has been analyzed.
