Apparently, up to 70% of the olive oil sold in the USA is mixed with cheap bad oils like sunflower and canola. It’s been discovered that 7 of the biggest olive oil makers in USA practice mixing the olive oil with cheap ones.
Such was the case in Italy back in 2008 when 400 police officers were involved in the operation Golden oil, during which 85 oil farms that mixed some percentage chlorophyll with sunflower and canola to the olive oil were seized. Even the Australian government investigated their own oils after finding out that the Italian oil was mixed, colored, perfumed and flavored. The results they got were shocking.
After these scandals, not one brand named extra virgin olive oil got the 2012 certificate of approval.
They were also the reason why the California University imported 124 oils to investigate. The results showed that more than 70% of the samples failed the tests.
Among them were:
- Antica Badia
- Whole Foods
- Felippo Berio
The brands who passed the tests were:
- Corto olive
- McEvoy Ranch Organic
- California Olive Branch
- Bariani Olive oil
- Olea Estates
- Cobram Estate
- Kirkland Organic
You can also do a testing at home. Take a bottle of olive oil and put it in the fridge for 30 min. if it gets solid, it is pure and has monounsaturated fats. If it stays liquid it is fake. You should also check for label approvals like Australian Extra Virgin Certified, or California Olive Oil Council Certified Extra Virgin.
