“Can I use inexpensive pomace olive oil for frying?” asks Lucila D. on today's #AskWardee. I'm sharing my thoughts below!
Lucila D. asks:
“I am writing to ask you about the safety of using pomace olive oil for frying. Here in Ecuador, coconut oil is too expensive, and I'm looking for a healthier option. The pomace olive oil here is a little cheaper. Thank you very much for your help.”
Before I give my answer…
Ever heard of pomace olive oil?
It's the last bit of oil that can be extracted from olives, making it decidedly not extra-virgin (that's the first pressing)…
…yet also pleasantly inexpensive.
Can or should it be used in a healthy kitchen, though? And what about for frying?
Olive pomace oil is olive oil that is extracted from olive pulp after the first press. Once the mechanical oil extraction of olive oil is complete, approximately 5-8% of the oil remains in the pulp, which then needs to be extracted with the help of solvents, an industrial technique used in the production of most other edible oils including canola, peanut, sunflower, etc. (Source.)
So did you catch that? To get the rest of the 5% to 8% oil left in the pulp after mechanical extraction (pressing), they use a solvent (or chemicals) to get the rest out. It’s the same way that other veggie oils are produced.
According to my research, the extraction process may also involve heat. So the pomace olive oil is also not cold-pressed. And there are several grades of pomace oil, from crude (unfiltered) to filtered.
Because of the solvent that may be in the oil, pomace olive oil is not called simply “olive oil” because it isn’t pure olive oil.
Is pomace olive oil healthy?
Due to the use of solvents and heat, I wouldn’t recommend pomace olive oil for consumption at all, let alone frying.
In fact, I don’t recommend any kind of olive oil for frying. It doesn’t have a high smoke point and is denatured quickly with high heat. Olive oil is susceptible to rancidity — much more so than coconut oil which tends to be shelf-stable for months, if not years.
This doesn’t mean you can’t sauté or oven roast vegetables occasionally using olive oil. Keep in mind that the extra virgin olive oil (first pressing) has the highest smoke point (400 degrees F) and will perform best here. But it is the most expensive. Mostly, I would reserve olive oil (extra virgin, if possible) for fresh uses — like salad dressings and drizzling on hummus or as a condiment.
I have now and then used pomace olive oil for making soap. I feel it’s an inexpensive choice and makes a good castile soap.
What are other inexpensive options for frying?
What pastured animal fat do you have locally that you could render for frying? These tend to be the cheapest and BEST fats for frying.
You might also look for grapeseed or avocado oils (expeller or cold-pressed) — their smoke points are even better than extra-virgin olive oil at 485 degrees Fahrenheit and 480 degrees Fahrenheit, respectively. I’m not sure what they cost in your area. Here in the United States, grapeseed oil is reasonably priced while avocado oil is expensive.
