Is avocado oil a seed oil?

Where the oil comes from

An avocado has a large stone in the middle and a thick, oily flesh around it. Avocado oil is pressed from that flesh, the same way olive oil is pressed from the flesh of an olive. The stone is not used. That is the whole botanical answer, and it is why avocado oil appears on every seed-oil-free list.

The fatty-acid profile follows the same pattern as other fruit oils: about 65-70% oleic acid (a monounsaturated fat), roughly 12% linoleic acid (the omega-6 the seed-oil argument is about), and around 12% saturated. Sunflower oil, for comparison, is near 68% linoleic.

The authenticity problem, which is the real one

Avocado oil has been a repeated subject of food-fraud testing. The most-cited work is a 2020 study from the UC Davis Olive Center, which chemically analysed 22 avocado oil samples bought in US shops and reported that the large majority were either oxidised before their best-before date or blended with cheaper oils — several samples were found to be substantially soybean oil, one of the oils a person buying avocado oil is usually trying to avoid.

The structural reason is dull and important: the United States has no standard of identity for avocado oil, so 'avocado oil' on a label is not a legally defined composition the way 'olive oil' grades are. Testing since then has continued to find adulterated product, though the picture varies by brand and batch and no single study should be read as the current state of every shelf.

Refined vs cold-pressed still matters

The seed-oil-free position rests on two arguments, not one: what the oil is pressed from, and how heavily it is refined. Avocado oil passes the first cleanly. The second depends on the bottle — refined avocado oil is bleached and deodorised to raise its smoke point for frying, the same process applied to industrial seed oils. Cold-pressed or virgin avocado oil is not.

Someone whose objection is to omega-6 content has little quarrel with either. Someone whose objection is to industrial refining should read the label rather than the fruit.

What Olive Detective does with it

Nothing negative. Avocado oil is not on the app's seed-oil flag list — scanning a product made with it will not raise a seed-oil warning, because it is not a seed oil. The app cannot tell you whether the avocado oil in a product is authentic; no barcode scanner can, because that is a laboratory question about a specific batch, not a question about an ingredient list.
