Extra virgin olive oil (EVOO) is widely regarded as one of the healthiest and most flavorful oils in the world. It’s a staple in Mediterranean cuisine and has been touted for its numerous health benefits, from reducing inflammation to improving heart health. However, there’s a long-standing debate about whether extra virgin olive oil is suitable for cooking. Some argue that its delicate flavor and high polyphenol content make it too precious for high-heat cooking, while others claim that it’s perfectly fine to use it for sautéing, roasting, and even frying.
The Chemistry of Extra Virgin Olive Oil
To understand whether extra virgin olive oil is suitable for cooking, it’s essential to delve into its chemical composition. EVOO is primarily composed of monounsaturated fats, particularly oleic acid, which is responsible for its distinct flavor and aroma. It also contains a range of polyphenols, including hydroxytyrosol, tyrosol, and oleocanthal, which have been shown to have potent antioxidant and anti-inflammatory properties.
One of the primary concerns about using EVOO for cooking is its relatively low smoke point, which is the temperature at which an oil begins to break down and smoke. The smoke point of EVOO can range from 320°F (160°C) to 420°F (220°C), depending on the quality and production methods. This is lower than other oils, such as avocado oil or grapeseed oil, which have smoke points above 520°F (271°C).
The Impact of Heat on Extra Virgin Olive Oil
When EVOO is heated, its chemical composition changes. The polyphenols, which are responsible for its health benefits, can degrade or become damaged, reducing their potency. Additionally, the heat can cause the oil to become oxidized, leading to the formation of unhealthy compounds.
However, it’s essential to note that not all heat is created equal. Gentle heat, such as that used for low-temperature cooking or dressings, is unlikely to cause significant damage to the oil. On the other hand, high-heat cooking, such as frying or sautéing at extremely high temperatures, can cause more extensive damage.
