Some olive oils, like Picual and Cornicabra, handle high heat better than others—they keep more of their good stuff and make less gunk when cooked.

Scientific Claim

Picual and Cornicabra extra virgin olive oils exhibit greater thermal stability than Arbequina and Manzanilla under heating at 170–200 °C, as evidenced by lower losses in tocopherols, reduced triacylglycerol polymerization, and more favorable lipid nutritional indices, suggesting variety-specific differences in resistance to thermal degradation.

Original Statement

“The most stable olive oils were Cornicabra and Picual... The least triacylglycerol polymers were observed in Picual olive oil... The analyzed oils were characterized by high initial quality, but they varied and depended on the olive variety... The order of stability based on nutritional indices: Cornicabra > Picual > Sensation > Armonia > Arbequina > Manzanilla.”

Effect of Heating Temperature of High-Quality Arbequina, Picual, Manzanilla and Cornicabra Olive Oils on Changes in Nutritional Indices of Lipid, Tocopherol Content and Triacylglycerol Polymerization Process

Cross-Sectional Study
In Vitro
2023 May 22

Scientists heated different types of olive oil and found that Picual and Cornicabra oils stayed healthier and broke down less than Arbequina and Manzanilla when cooked at high heat, just like the claim said.

Similar Assertions

Some olive oils — like Picual and Cornicabra — hold up better when heated than others, like Arbequina and Manzanilla, because they lose fewer healthy compounds and form less gunk when cooked.

Some types of olive oil — especially Cornicabra and Picual — hold up better when heated than others like Arbequina, meaning they break down less and make less gunk when frying.

When olive oil gets super hot (200°C), it starts forming gummy, sticky molecules called dimers—some oils make way more than others, especially blends high in Arbequina, while Picual makes the least.

When you heat certain types of olive oil really hot, the healthy antioxidant called alpha-tocopherol disappears completely in some kinds, but not as much in others — Picual and Cornicabra oils hold up better.

When you heat olive oil really hot (200°C), the good antioxidants called tocopherols disappear—some oils lose them completely, while others like Picual and Cornicabra keep a little bit left.
