The University of California - Davis conducted a study to see whether or not those olive oils labelled "extra virgin" truly were. The startling results can be read here. To sum them up, up to 69% of imported extra virgin olive oils are fraudulently labelled.
When I found this out, I had to know if my Terra Delyssa extra virgin olive oil was true or not. On Crunchy Betty, she reveals a quick trick to find out for yourself at home. Pour a small amount of your oil into a container, and cover it. Place this in the fridge for 24-48 hours. When you remove it, you will have your results. Crystallization means it is extra virgin, a solidified lump means it is not.
My results:
The Terra Delyssa fraud has solidified while our new Kirkland organic has only crystallized.
Here is a concise list of the discovered truthful and fraudulent oils. See where your olive oil ranks. If it's not there, try the test at home.
Do you use extra virgin olive oil? Will this change what you purchase?

i'll test my No Name (superstore) evoo and report back! i have a bit left in the bottle, but need to get more soon so this is appropriately timed.
ReplyDelete24 hours in... it's looking more like the solidified cup in your picture. it's a really thick liquid, murky colored, and no crystals. see what it looks like tomorrow, but it's not promising. and i'm not really surprised...
DeleteYikes. Though I wouldn't have expected much from No Name either. I just can't believe so many companies get away with fraud.
DeleteI am almost out as well, but I will test my oil I bought at Sam's. I plan to buy some organic olive oil from Azure Standard next month so I will have to check and see if they carry the ones that passed the test. Thanks for posting this!
ReplyDeleteVery informative post. Thanks!
ReplyDeleteGood information to have, thank you.
ReplyDeleteVery informative post. Olive oil Thanks!
ReplyDeleteI just tested my napa valley naturals olive oil that I got my local co-op and it was a solid lump! So disappointing. I don't have a costco in my town and I haven't seen any of the "good" brands in the store. I'll have to try to find an olive oil that is actually extra-virgin.
ReplyDeleteOh no! Good luck!
Deletewow, I'm planning to test mine right now! thanks for this post.
ReplyDeleteYou got your test backwards. Pure olive oil will solidify in the fridge. Please correct this posting.
ReplyDeleteYes, this test is backwards... hopefully those who have read this have not tossed out their pricy extra virgin olive oils thinking they were duped!!!! Please correct this asap! http://consumers.californiaoliveranch.com/2013/02/19/checking-if-your-olive-oil-is-extra-virgin-1-tip-dont-use-the-fridge-test/
