Most Avocado Oil Is Impure or Rancid: What to Know
Avocado oil is widely utilized for its monounsaturated fat and antioxidant content, though market research indicates widespread issues regarding commercial purity and freshness. org, found that over 70 percent of tested private-label samples were either rancid prior to purchase or adulterated with other oils. Adulterants identified in products labeled as pure avocado oil frequently included soybean oil and sunflower oil.
Unadulterated avocado oil is typically green or pale yellow, with a mild, buttery, or grassy flavor profile. Rancidification or oxidation can alter the color to a dull brown and produce a bitter or musty odor. Additionally, oxidation diminishes the oil's fatty acid stability and antioxidant constituents. Storage in dark glass containers is recognized as a factor that slows photo-oxidation compared to storage in transparent or plastic packaging.
