Seeing a lot of comments about how supposedly a lot of EVOO sold on store shelves isn't actually pure olive oil, and I'm curious where this belief comes from. Any data or studies you can point me to?

Here's an FDA report of 88 EVOO bottles purchased from supermarkets that were tested, three of which were identified as impure enough to possibly indicate they were adulterated: https://www.researchgate.net/publication/286479191_Authentic...

It's not "adulteration" so much as fraud by mixing it with cheaper oils or labeling oil as "extra-virgin" when it's not.

That's what "adulteration" means. From the study I referenced:

"Three of the 88 samples labeled as EVOO failed to meet purity criteria, indicating possible adulteration with commodity oil and/or solvent-extracted olive oil."

3 out of 88 is not that bad. If you read this thread everyone is thinking most EVOO is adultered. If you buy from a trustworthy company, you would most likely be ok.

We only use OO in our house and almost all of it from Cosco.. Refined + 15% EV for cooking and Organic cold press EV for salads and cold dishes.
