In one study, researchers used several commercial oils for deep frying and took samples of each oil every three hours. The diagram below shows one example of a polyunsaturated fatty acid which, in this case, has two double bonds; Since olive oil is around 90% saturated and monounsaturated fat, it is fairly resistant to oxidation. You acknowledge that: Based solely on personal opinion, I expect ghee would display better oxidative stability, but those who worry about the effect on LDL etc may prefer to use olive oil.   Its savory flavor balances out the sweetness in olive oil cake and muffins or olive oil granola. We nevertheless reserve the right to update this information at any time. They reported that canola oil was the most unstable of all the oils tested, producing more than 2.5 times the amount of polar compounds of extra-virgin olive oil and about twice that in heated refined olive oil.   Amazing new research on the microbiome. This website may contain links to other websites (“linked websites”). This double bond can be broken, which makes monounsaturated fat slightly more prone to oxidation than saturated fat (11). According to the USDA Food Composition Database, extra virgin olive oil contains the following amounts of fatty acids per 100 grams (9); Firstly, there are three primary groups of fatty acids, and these are as follows; All three of these fats contain the elements carbon and hydrogen.

In one study, researchers deep-fried (160–190°C) and pan-fried (180°C) potatoes in 4 different refined oils – olive, corn, soybean, and sunflower – and used the same oil … (a)  prior to entering into these terms and conditions you have been given a reasonable opportunity to examine and satisfy yourself regarding all goods and services which are the subject of these terms and conditions and that prior to entering into these terms and conditions you have availed yourself of that opportunity; and The application of the United Nations Convention on Contracts for the International Sale of Goods (the Vienna Convention) to these terms and conditions (by virtue of any law relevant to these terms and conditions) is excluded. Either way, they are both fairly heat-stable cooking oils, and each has its own merits. Are there different types of coconut oil? Copyright Saturated fats are the most stable fatty acids, hence they are most resistant to oxidation (4). I would love to see a study like the one referenced that included all the different animal fats.

It's not about the smoke point Despite the fact that the smoke point of extra virgin olive oil exceeds home cooking temperatures, there is a persistent myth that it is unsuitable for cooking.   For example, a recent study compared the chemical and physical changes in ten commercial oils while heating them at a temperature of 180°C (356°F), among various other heat/time tests (15).

Yes, there are different types of coconut oil – refined coconut oil has a smoke point of around 450°F (232°C). As a result, they have different colors, tastes, and health properties.
