Is Avocado Oil Fake? How to Spot Adulterated Brands

You switched from canola oil to avocado oil to avoid seed oils. Good move — except there is a problem. The avocado oil you bought might not actually be avocado oil.

Multiple university studies have found that a shocking percentage of avocado oils on store shelves are adulterated — cut with cheaper soybean, sunflower, or safflower oil, or so heavily oxidized that they have gone rancid before you even open the bottle. If you are paying a premium for avocado oil specifically to avoid seed oils, you need to know which brands you can actually trust.

The Studies That Exposed the Problem

In 2020, researchers at UC Davis published a study that sent shockwaves through the clean eating community. They tested 22 avocado oil brands sold in the United States and found:

• 82% of the samples were either adulterated or oxidized beyond acceptable levels
• Several brands labeled "pure" or "extra virgin" avocado oil contained significant amounts of soybean oil or sunflower oil
• Some brands that were technically pure avocado oil had gone rancid — meaning the oil had degraded before the consumer ever opened it
• Only 2 out of 22 brands were both pure and fresh

Follow-up studies in 2022 and 2024 found similar results. The avocado oil market remains one of the least regulated and most fraud-prone segments of the cooking oil industry.

Why This Happens

Avocado oil is expensive to produce. A liter of genuine extra virgin avocado oil costs significantly more to manufacture than the same amount of soybean or sunflower oil. That price difference creates a strong financial incentive for fraud.

Here is how it works:

1. Blending with cheap oils. A manufacturer mixes 70% soybean oil with 30% avocado oil, bottles it, and labels it as "pure avocado oil." The taste difference is subtle enough that most consumers cannot tell.

1. Rancidity at production. Some manufacturers use low-quality or damaged avocados. The resulting oil is technically avocado oil but has already begun to oxidize before bottling. It is "real" avocado oil — just bad avocado oil.

1. Weak labeling laws. Unlike olive oil, which has established international standards and testing protocols, avocado oil has no widely enforced purity standards in the United States. There is no regulatory body routinely testing avocado oil for authenticity.

Which Brands Passed the Tests

Based on the UC Davis study and subsequent independent testing, these brands have consistently tested as pure, fresh avocado oil:

Brands that passed:

• Chosen Foods — Consistently pure in multiple rounds of testing. Widely available at Costco, Walmart, Target, and Whole Foods. This is our top recommendation for everyday cooking.
• Marianne's — Passed UC Davis testing. Smaller brand, available online and at some specialty stores.
• CalPure — California-produced, tested pure. Limited availability.

Brands with mixed or poor results:

We are intentionally not naming the brands that failed, as formulations may change over time and we do not want to be inaccurate. Instead, use the verification methods below to check any brand yourself.

The safest approach is to stick with brands that have been independently tested and verified, and to buy from retailers with high product turnover so you are not getting bottles that have been sitting on shelves for months.

How to Spot Fake Avocado Oil Yourself

You cannot test oil purity at home with laboratory accuracy, but there are several practical checks that catch the worst offenders:

1. The Fridge Test

Put your avocado oil in the refrigerator for a few hours. Real avocado oil will become slightly cloudy and thicker (similar to olive oil). If it stays completely clear and liquid, it may contain a high percentage of refined seed oils that do not solidify at cold temperatures.

This is not a definitive test — refined avocado oil also stays relatively clear — but it can catch blatant fraud.

2. Check the Color

Genuine unrefined avocado oil has a distinct green color. Refined avocado oil is lighter but still has a slight golden-green tint. If your "avocado oil" is pale yellow with no green tint at all, it may be predominantly soybean or sunflower oil.

3. Smell and Taste

Real avocado oil has a mild, slightly buttery, slightly grassy flavor. It should not taste harsh, bitter, or like nothing at all. Rancid avocado oil tastes musty, stale, or like old crayons. If your oil has no discernible flavor, it is likely heavily refined or adulterated.

4. Check the Label Details

Look for:

• Single origin. "Product of Mexico" or "Product of USA" is better than "Packed in USA" (which means the oil came from somewhere else).
• Harvest date or best-by date. A best-by date means the company tracks freshness. No date at all is a red flag.
• "Extra virgin" or "cold-pressed." These terms suggest less processing, though they are not regulated for avocado oil the way they are for olive oil.
• Third-party testing claims. Some brands now advertise independent purity testing. This is the strongest signal of quality.

5. Price Check

Genuine avocado oil costs more to produce than seed oils. If a bottle of avocado oil costs roughly the same as canola oil, something is wrong. A 16oz bottle of quality avocado oil typically costs $8-14. If you are seeing it for $4-5, be skeptical.

What to Use Instead

If the avocado oil fraud problem makes you uneasy, there are other clean cooking oils that have much lower fraud rates:

• Extra virgin olive oil — Better regulated, widely tested, and far harder to fake at scale. Use for medium-heat cooking and dressings.
• Butter or ghee — Impossible to fake. Grass-fed versions like Kerrygold are clean and affordable.
• Coconut oil — Low fraud risk. Great for baking and medium-heat cooking.
• Animal fats (tallow, lard) — Zero fraud risk. Increasingly available from clean meat suppliers.

You do not have to give up avocado oil — just buy verified brands and use the checks above. But having alternatives in your rotation means you are not dependent on a single oil category with known integrity issues.

Key Takeaways

• Up to 82% of avocado oils tested were adulterated or rancid according to UC Davis research
• Chosen Foods is the most widely available brand that consistently passes purity testing
• Use the fridge test, color check, smell test, label review, and price check to evaluate any brand
• Stick with trusted retailers that have high product turnover
• Have alternative clean oils in rotation — EVOO, butter, ghee, coconut oil, tallow
• The avocado oil industry needs better regulation, but until then, informed consumers are their own best defense
