Can tea extracts protect extra virgin olive oil from oxidation during microwave heating?

► Oxidative stability of olive oil with tea extracts under microwave heating was tested. ► White and green tea extracts were added to olive oil. ► Until 3 min of heating tea extracts were effective antioxidants. ► With higher exposition times tea extracts were pro-oxidants, mainly green tea. ► Microwave heating induced nutritional and quality losses in all olive oils studied.
