Myth - The Olive Oil Fridge Test
MYTH - The Olive Oil Fridge Test
An often perpetuated myth related to olive oil is the “Fridge Test” - a supposedly simple home test for olive oil authenticity. The myth is so widespread that you may even see conflicting versions of the test – some say your oil should solidify if it’s real, and others say it should not solidify if it’s real. If only it were that easy! This “test” unfortunately, is completely false and misleading. Read on to see why even the rumour-mongers are confused on this one.
Almost all oils will become cloudy and eventually solidify at cold temperatures. Generally speaking, refined oils (such as regular olive oil or vegetable or seed oils) will solidify at a lower temperature than extra virgin olive oil. However, the time and the level of cold required to get to the solidification stage are greatly affected by the overall chemical compounds of the oil. These include the contents of the saturated fatty acid chains, like palmitic or stearic acid, that can change the melting-point of the triglycerides (the main constituent representing almost 98% of all oils and fats) and other compounds in oil, as well as the presence of natural waxes.
The profile of an olive oil, and especially Extra Virgin Olive Oil, is incredibly diverse because the oil’s makeup is affected by so many natural factors that vary by region, season, and type of olive. These include:
There is no simple magic home test to check for olive oil authenticity. Extra virgin olive oil will crystallize and/or solidify at a wide variety of time and temperature exposures. All this variance is what makes extra virgin olive oil truly special. Forget the fridge, and focus instead on enjoying the wide variety of flavours found amongst extra virgin olive oils.
