Some Avocado “Oils” Are Not What They Seem

NEW STUDY: 89% of “Avocado Oil” Foods Use Fake or Adulterated Avocado Oil

The vast majority of chips, salad dressings, and mayonnaise labeled as containing avocado oil showed fatty-acid and sterol profiles inconsistent with authentic avocado oil.

newly published study out of UC Davis has uncovered a stunning problem hiding inside foods marketed as being made with avocado oil: 89% of avocado-oil-labeled products tested had chemical profiles inconsistent with authentic avocado oil. They analyzed oils extracted from 74 commercially sold chips, salad dressings, and mayonnaise products labeled as containing avocado or olive oil, using fatty-acid and sterol markers referenced against Codex Alimentarius standards.

The results were especially striking for avocado oil. Among avocado-oil-labeled products, 93% of chip samples failed authenticity criteria, 100% of salad dressings failed, and 71% of mayonnaise samples failed. In total, just 6 of 54 avocado-oil-labeled samples were classified as compositionally consistent with authentic avocado oil.

The product identities below come from the UC Davis-linked product list corresponding to the study’s numbered samples. Each product was represented by two separately purchased lots. For readability, I label lots that were compositionally consistent with authentic avocado oil as REAL AVOCADO OIL and lots that were compositionally inconsistent as ADULTERATED:

The study physically extracted the oils from the finished foods and analyzed their fatty-acid and sterol composition using gas chromatography with flame-ionization detection (GC-FID). Many avocado-oil products showed profiles inconsistent with authentic avocado oil, including low palmitic and palmitoleic acids and elevated sterol markers associated with other vegetable oils. The authors said these patterns were consistent with substitution or dilution with vegetable oils.

One sample was particularly remarkable: its fatty-acid profile contained 52.5% linoleic acid and 6.5% alpha-linolenic acid, while oleic acid was only 24.8%—a pattern investigators said was consistent with soybean oil composition. Many other avocado-oil-labeled samples clustered chemically near comparator products containing canola, corn, soybean, and/or sunflower oils rather than authentic avocado oil.

The contrast with olive oil was dramatic. 90% of olive-oil chip samples and 100% of the olive-oil salad dressings and mayonnaise samples were classified as consistent with authentic olive oil. The authors noted that olive oil has more established standards and considerably more developed regulatory oversight than avocado oil.

Those paying a premium for processed foods prominently marketed as containing avocado oil appear to have been seriously duped.
