Apparently, even 70% of olive oil sold in the U.S. stores is fake, as they have been cut with cheaper, inferior oils like canola and sunflower oil! This is similar to the 2008 practice in Italy. This meant seizure for 85 oil farms that mixed some percentage chlorophyll with sunflower and canola to the olive oil.
The oil was mixed, colored, perfumed and flavored too, and these things made the Australian government investigate their oils. The results were awful. After that, not one brand named extra virgin olive oil got the 2012 certificate of approval.
These scams made the University of California to study 124 imported brands of extra virgin olive oil and discovered that more than 70% of the samples did not pass the test.
THESE ARE THE BRANDS THAT FAILED THE TEST:
ON THE OTHER HAND, THE FOLLOWING BRANDS ARE TRUSTWORTHY:
McEvoy Ranch Organic
Bariani Olive Oil
California Olive Ranch
HOW TO TEST OLIVE OIL:
Additionally, you can also test the olive oil you have at home. You should put the bottle in the fridge for half an hour, and if it starts to solidify, it means that the oil is pure, as it contains a large amount of monounsaturated fat.
On the other hand, if it does not solidify, it is fake. Yet, just to be sure, look for official governmental seals of approval on the label, like “Australian Extra Virgin Certified” and “California Olive Oil Council Certified Extra Virgin.”
