With EVOO there is at least a certification seal from the COOC for California-based olive oils. Not only does that certify oil quality and safe storage practices-- it certifies that it is actually olive oil. This is necessary because, according to various sources I've read, there's a better chance than a coin flip that the EVOO bought at the grocery store is a) some other oil (and dyed green), b) cut with other cheaper oils, or c) substandard non-virgin olive oil. So I guess my question is-- how do you know that the avocado oil isn't fake? Is there a certification body? Without one, it seems like the current popularity of it would push manufacturers to use the same tricks as with EVOO. But again, I'm not even talking about quality or storage-- just whether it is actually the oil claimed by the label on the bottle. I mean-- there's a oil manufacturer literally called "California Olive Ranch" that does an oil with a little graphic that says something like "Global Blend!" And apparently they used to be COOC certified manufacturer but got the cert revoked because there's rule that putting "California" on the label requires all the olives to be from California (obviously). Hell, there was even a story about a mysterious proposal to change some of the language in the certification guidelines to soften this rule, but a lot of the members petitioned against that. Given this weirdo shady oil environment I'm just assuming everything is either dyed vegetable oil or some other trick unless I can get my hands on a really good reason to believe otherwise.
