Olive Oil Refrigerator Test

Bragg Olive Oil

Dr. Oz advocated a “fridge test” as a way to authenticate the quality of extra virgin olive oil. He qualified that the fridge test was not 100% reliable in detecting either the purity or quality of olive oil. All olive oils contain a small amount of saturated fatty acids that solidify at room temperatures. The amount of solidification is directly proportional to the amount of saturated fatty acids in the oil which depends mostly on the varieties of olives used to make the oil and to a lesser extent where the olives were grown. Solidification does not indicate freshness, purity, flavor, extra virgin grade, or any other quality parameters. A study conducted by the University of California Davis Olive Oil Center, showed that after refrigerating 7 samples of different types of oil, including 2 samples of extra virgin olive oil, some showed minor congealing at the bottom of the bottles but none solidified completely. The study noted that although it is true that waxes and long chain fatty acids in extra virgin oil can lead to the oil solidifying in the cold, relative amounts of these compounds vary.

  3. I’m always happy with the quality of Bragg’s products. Is this olive oil USDA certified organic?
