Mixing a high-PUFA olive oil (Arbequina) with a more stable one (Picual) makes the blend more heat-resistant—less gunk forms when you fry with it.

Scientific Claim

Blending Arbequina and Picual olive oils in a 70:30 ratio (Sensation) reduces triacylglycerol polymerization at 200 °C compared to pure Arbequina or Armonia (70% Arbequina), indicating that blending oils with lower PUFA content can mitigate thermal degradation.

Original Statement

“The samples analyzed, including the olive blends (Armonia and Sensation), were commercially purchased... The addition of refined coconut oil to olive oil allowed the frying sessions... to be extended... A similar effect can be observed for Sensation olive (a blend of Arbequina and Picual). Mixing them in the right proportion led to a decrease in the share of PUFA (Arbequina) and an increase in the share of MUFA (Picual). After heating at 200 °C, the level of TAG polymers was low (2.28%).”

Cross-Sectional Study

In Vitro

2023 May 22

The study looked at different olive oils when heated, and found that oils with more Picual (not Arbequina) held up better under heat — but the claim got the mix backwards, saying a 70% Arbequina blend works best, when the study actually tested a 70% Picual blend.

Similar Assertions

Mixing olive oil with more Picual (which has more monounsaturated fat) makes it less likely to form gummy polymers when heated, compared to mixing with more Arbequina.

84%

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.

78%

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.

78%

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.

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.
