Study Finds 89% of Products Claiming Avocado Oil Use Cheaper Alternatives
University of California, Davis researchers discovered widespread adulteration in snacks, mayonnaises, and salad dressings.
A significant majority of food products marketed as containing avocado oil are adulterated with cheaper alternatives, according to a study by scientists at the University of California, Davis. The research, which tested 54 products claiming to be made with avocado oil, found that 89% were bulked out with less expensive oils, contradicting consumer expectations and potentially misrepresenting product quality and health claims.
Avocado oil has gained popularity among health-conscious consumers, who often pay a premium for products featuring it. "Consumers are increasingly paying a premium for products made with avocado oil or olive oil," said lead author Selina Wang, Professor of Cooperative Extension in the UC Davis Department of Food Science and Technology. "They deserve to get what they pay for and food manufacturers deserve confidence that the ingredients they purchase from suppliers are authentic."
The study revealed specific rates of adulteration across different product types. Among chips labeled with avocado oil, 93% contained other oils. For mayonnaises, the figure was 71%, and 100% of salad dressings claiming to be made with avocado oil were found to contain other oils. In contrast, purity tests on 20 olive oil-labeled products showed only one failure.
Researchers suggest that blame may not lie with the brands producing these items. Many food companies rely on third-party brokers for their oil supply and may be unaware that the oil they procure is compromised. "If consumers are buying potato chips that say they're made with 100% avocado oil, that should be the product that they're getting," Professor Wang stated. "I don't think there is enough accountability throughout the supply chain. Suppliers of adulterated oil may be hiding behind a couple of layers of supply chain, making it difficult to identify where the problem originated."
This finding highlights a lack of transparency and accountability within the food supply chain, where the authenticity of premium ingredients can be compromised before reaching the end consumer.
