A recent study conducted by the University of California, Davis has shed light on the misleading practices surrounding avocado oil products. Astonishingly, the study found that only 31% of the tested avocado oil products were truly pure, while 36% met the quality standards as advertised. Interestingly, it was observed that low-cost products were more susceptible to adulteration. In response to these findings, researchers are now working towards establishing enforceable standards for avocado oil purity and quality. They have also identified chemical markers that can assist professional retail buyers in making more informed decisions, benefiting both consumers and fair producers in the industry.
Avocado oil has gained immense popularity in recent times due to its cardiovascular benefits and versatile culinary applications. However, the quality of avocado oil products available in the market varies significantly. Many products that claim to be “pure” avocado oil often contain other oils or additives. Unfortunately, there are currently no strict regulations in place that define the chemical and physical properties of avocado oil.
The research team at the University of California, Davis analyzed 36 privately branded avocado oil products to assess their purity and quality. These privately labeled products are typically manufactured by external companies but marketed under the brand label of grocery stores or retailers.
The findings of the study, published in the journal Food Control, revealed that only 31% of the tested samples were pure, and 36% met the advertised quality standards. Quality refers to whether the oil is fresh or has deteriorated due to factors such as aging, heat, or light exposure. To determine purity, the researchers measured fatty acids, sterols, and other components that distinguish avocado oil from other oils.
The study encompassed oils purchased from 19 retailers in the United States and Canada, covering a range of price points. The researchers discovered that lower-priced oils were more likely to be adulterated with other oils.
“While low-cost products showed a higher probability of adulteration, high cost did not guarantee purity or quality,” stated Selina Wang, associate professor of Cooperative Extension in the Department of Food Science and Technology at UC Davis. Wang co-authored the paper alongside Hilary Green, a postdoctoral researcher at UC Davis.
Furthermore, the researchers identified specific chemical markers in avocado oil that professional retail buyers can utilize to make more informed decisions when selecting suppliers. This knowledge empowers consumers to have confidence in the avocado oil products they purchase.
This study marks the second comprehensive investigation conducted by UC Davis researchers on the quality of avocado oil available in the United States. The initial study, released in 2020, revealed that many of the tested samples were of poor quality, mislabeled, or adulterated with other oils.
Selina Wang emphasized that since the first UC Davis study, there has been a collaborative effort between researchers, industry leaders, and government agencies to establish enforceable standards. To this end, the Avocado Oil Expert Group was established in partnership with the American Oil Chemists’ Society to explore potential standards and future research projects.
Wang’s research group has been investigating how natural factors such as different avocado varieties, harvest times, geographic origins, and processing methods can affect the chemical composition of avocado oil. They aim to develop standards that account for natural variations while detecting any adulterations.
Wang expressed optimism about the future of the avocado oil industry, drawing a parallel with the significant improvements seen in the quality and purity of olive oil over the past decade. She believes that establishing fair standards and eliminating fraudulent products will pave the way for avocado oil to follow a similar trajectory.

This is gr8 news! Now we can make smarter choices when buying avo oil. Gotta look out for those chemical markers. Let’s spread the word and demand better quality!
so if I buy cheap avo oil, there’s a bigger chance it’s not legit? Not cool! We need to be able 2 trust the products we buy, no matter the price!
Thx 4 the info! I luv avo oil, but now I’m worried abt what I’m buying. I hope they set up those fancy standards soon so we can be sure we’re getting the real deal!
Wow, I had no idea some avo oil products are so sketchy. I’m relieved to hear that researchers are working on enforceable standards. We deserve to know what we’re putting in our bodies!
omg this study is shocking! Only 31% of avo oil products rly pure? That’s cray cray! We need strict regulations ASAP!
