Olive Pomace Oil: What It Is and Isn’t

Olive pomace oil sits at the bottom of the price ladder, and the label rarely explains what it is. It is a genuine product with genuine uses, but it is made in a completely different way from the oil in a green-tinted extra-virgin bottle. Knowing the difference saves both disappointment and money.

Extra virgin is fruit juice: olives crushed and the oil separated by purely mechanical means, nothing more. Olive pomace oil begins where that process ends — with the damp solid left in the mill. Everything that makes the two products different flows from that one fact. One is squeezed from fresh fruit; the other is chemically coaxed out of what the fresh pressing left behind, then refined until it is almost flavourless. Both are legal and both have their place, but they are not the same thing, and the price gap between them is honest.

How it is actually made

When olives are milled and the oil separated, a damp solid mass is left behind — skins, pulp and broken stones, called pomace. It still holds a little oil, but not enough to squeeze out economically. So that residual oil is extracted with heat and food-grade solvents (typically hexane), then refined to strip the harsh flavours and high acidity. The result is nearly tasteless and pale. To make it palatable, and to earn the word ‘olive’, a little virgin olive oil is blended back in. The finished product must be labelled ‘olive pomace oil’ — never simply ‘olive oil’ and never ‘extra virgin’.

What it is good for

None of this makes pomace oil fraudulent; it is legal, regulated and honestly named when the label is read properly. Its high smoke point and neutral taste make it a workable, cheap fat for deep-frying and high-heat cooking, which is why caterers and some restaurants buy it by the drum. What it is not is a substitute for extra virgin on a salad or a finished dish — the flavour and most of the antioxidants that make good oil worth having have been refined away. Buy it for the frying pan if you like, but read the tin, because the gap between ‘pomace’ and extra virgin is the whole story.

The word that gives it away

Here is the tell the trade relies on: the name itself. However rustic the leaves and groves printed around the label, if the front says ‘pomace’ you are buying refined, solvent-extracted oil. Some packaging leans hard on the olive imagery precisely because the honest words are unglamorous. That is fine — there is nothing to hide if you are frying at a low price — but it means you should never pay an extra-virgin price for it, and never expect it to taste of anything on bread.

Buying and using pomace oil

• Read the front of the tin: the word ‘pomace’ is the whole story.
• Use it for deep-frying and high heat, where its neutral taste and high smoke point suit.
• Never pay an extra-virgin price for it — it is the cheapest grade for a reason.
• Do not expect it to taste of anything raw; the flavour has been refined out.
• Keep a separate finishing oil for salads and bread — pomace cannot do that job.

Olive pomace oil: common questions

Is olive pomace oil real olive oil?

It comes from olives, but it is a separate, lower grade. It is solvent-extracted from spent paste and refined, then lightly blended with virgin oil — and must be labelled ‘pomace’, never ‘extra virgin’.

Is pomace oil safe to eat?

Yes. It is a legal, regulated food oil; the solvent is removed during refining. It is simply a refined, near-flavourless product rather than a fresh, unrefined one.

What is pomace oil good for?

Deep-frying and high-heat cooking. Its neutral taste and high smoke point make it a cheap, workable frying fat — which is why caterers buy it in bulk.

Why is it so cheap?

Because it is made from a by-product — the paste left after the real oil is pressed — and heavily refined. The low price is honest; it reflects what it is.

Can I use it on salads?

You can, but there is little point: refining has stripped the fruit and most antioxidants. For raw finishing, keep a fresh extra virgin instead.
