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.

Scientific Claim

Heating extra virgin olive oils at 200 °C increases triacylglycerol dimer formation by 2.5- to 6.5-fold compared to heating at 170 °C, with Armonia (70% Arbequina) showing the highest polymerization (5.17%) and Picual the lowest (1.14%), demonstrating that fatty acid composition influences thermal polymerization rates.

Original Statement

“At the lower heating temperature, these compounds were observed only in Armonia olive [0.79%]. The higher process temperature led to the formation of more of these compounds... their content ranged from 1.14% (Picual) to 5.17% (Armonia).”

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

The study heated different types of olive oil at two temperatures and found that hotter oil made more gummy stuff, especially in some types like Armonia and less in Picual — just like the claim says.

Similar Assertions

When olive oil gets super hot, it starts forming gummy, big molecules called dimers — and the amount depends on the type of olive oil: blends with more Arbequina make way more than those with more Picual.

When olive oil gets really hot, it starts forming sticky, gummy molecules — and some types (like Armonia) make way more of them than others (like Picual).

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.

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.
