Adding sesame oil to extra virgin olive oil doesn’t make it last longer when frying because it’s already packed with natural antioxidants.

Scientific Claim

Adding sesame oil to extra virgin olive oil does not significantly extend its frying time, as EVOO blends maintain a consistent frying duration of approximately 25–26 hours regardless of sesame oil concentration, due to EVOO’s already high antioxidant capacity.

Original Statement

“The EVOO frying time was not increased by SO blending and was approximately the same (25–26 h) for all blends. This is due to the higher antioxidant content of EVOO, indicating the higher nutritional value and health benefits of EVOO in comparison to OO.”

Cross-Sectional Study

The study found that adding sesame oil to regular olive oil helps it last longer when frying, but it doesn’t help extra virgin olive oil last any longer—because EVOO is already super good at resisting heat damage.

Similar Assertions

Adding a little sesame oil to regular olive oil helps it last longer when frying food because it slows down the oil going bad.

80%

After frying for 12 hours, regular olive oil loses almost all its healthy compounds, but extra virgin olive oil still keeps about a third of them — adding sesame oil doesn’t help preserve them.

78%

At the start of frying, mixing sesame oil makes olive oil more antioxidant-rich, but after 12 hours, all oils lose their antioxidant power — extra virgin olive oil just starts higher and lasts a bit longer.
