Biosensor analysis for the kinetic study of polyphenols deterioration during the forced thermal oxidation of extra-virgin olive oil.

Computational/Algorithm Study

2008 Feb 15

Scientists heated olive oil at different high temperatures and measured how fast the healthy compounds (polyphenols) broke down. They found out exactly how long it took for half of them to disappear at each temperature — which is exactly what the claim was asking.

When you heat olive oil really hot, the healthy compounds called polyphenols break down faster the longer and hotter it gets.

When you heat olive oil at high temperatures for a long time, it makes more of two harmful chemicals—HNE and ONE—than the other oils, because olive oil is mostly made of oleic acid.

When you heat olive oil really hot (200°C), it loses all its protective antioxidants and turns into more gunk than when heated at a lower temperature (170°C).
