Conclusions
The results obtained in the present study showed that the rosemary extract is a promising source of natural antioxidants for vegetable oils, being able to protect the oils against oxidative processes, even at high temperatures, once its efficiency measured by the PDSC technique was better than the one of the synthetic antioxidant TBHQ. Another parameter to be taken into account deals with the thermal stability of the rosemary extract, which, by means of thermogravimetric analyses was shown to be stable at the frying temperature of the oils, a property that is not found in the majority of the antioxidants commonly used in edible oils.
