How To Test The Purity Of Olive Oil?

The Fridge Test

Two Step Olive Oil Purity Test

1. Pour 2-4 tbsp of olive oil into a clean glass jar.  Seal the jar.

2. Put the jar in the refrigerator for 24 hours.

If the oil solidifies, it’s monounsaturated and is olive oil.

If the oil remains a liquid, it is polyunsaturated and is NOT olive oil.

The Debate

Flynn told Olive Oil Times that the results of the experiment, which were released today, showed that the Fridge Test is an unreliable indicator of olive oil quality.

Seven oil samples, including EVOO, lesser grade olive oils, olive oil blends and non-olive oils were placed in a refrigerator and checked at intervals up to 180 hours. Although no samples fully solidified, a sample of EVOO mixed with up to 50 percent lesser grade olive oil congealed in the bottles, meaning it could be interpreted as passing the refrigerator test even though it was not pure EVOO. The study concluded that the Fridge Test is not reliable for determining oil purity or quality.

So What Can I Do

The Taste Test

Good olive oil is often bitter, pungent, spicy, and slightly abrasive. It’s not always smooth and easy going. In fact, the “off-notes,” the intense flavors that make the uninitiated screw up their face actually indicate the presence of high levels of polyphenols, those antioxidant plant compounds which make olive oil so good for you. If the olive oil you taste burns the back of your throat and tastes funny to you, chances are you’ve been using and are used to adulterated (or at least non-virgin) oil.We provide premium extra virgin oil tasting event.We are encouraging participant to bring their home use olive oil to the event to do a comparison .Please visit http://evooingredient.blogspot.com/search/label/Our%20Service for more details.

Avoid clear bottles
First reason being, light exposure oxidizes olive oil and degrades the polyphenol content. Second reason, most quality olive oil producers care about their product enough to ship it in suitable vessels.
