Extra virgin olive oil lasts longer when frying than regular olive oil because it has more natural antioxidants built in.
Scientific Claim
Extra virgin olive oil exhibits greater resistance to oxidation during deep frying than regular olive oil, as evidenced by a 3.75-hour longer frying time (25.25 h vs. 21.5 h) and lower anisidine values, attributable to its higher initial phenolic content.
Original Statement
“EVOO was more resistant to oxidation than OO, as measured by the TPCs and TEAC, while the frying time rose from 21.5 to 25.25 h when EVOO replaced OO. The AV for EVOO was lower than OO and all tested blends, even those with EVOO.”

Assessment Explanation
The study directly measured and compared oxidation markers (TPCs, AV) and frying duration between two defined oil types under identical conditions. The differences are quantified and reproducible.

EVOO lasts longer in the fryer than regular olive oil because it has more natural antioxidants, which keep it from going bad as fast.
